OpenLens vs Semrush AI Visibility Toolkit: An Honest 2026 Comparison for Agencies
OpenLens and the Semrush AI Visibility Toolkit solve overlapping problems but for different agency stages — Semrush is the right pick for agencies already paying for the Semrush suite who want AI visibility as a checked-box add-on; OpenLens is the right pick for agency-native, multi-client work where source-level URL granularity matters more than prompt-volume estimates.
That sentence is the entire decision. Everything below this line is the evidence — pricing tiers with exact 2026 numbers, the LLM-coverage table, the agency-feature breakdown, and an honest concession block on when to pick Semrush anyway. If your agency already runs on Semrush Business or Guru and your buyer wants AI visibility data inside the dashboard they already log into every morning, scroll to the "When to pick Semrush" section. If you run an agency at any scale — from a single client up to hundreds in parallel — each on a $1,500-$8,000/mo retainer and you're trying to fit AI visibility into the deliverable stack without consuming a Semrush seat per client, the rest of this piece is for you.
At-a-glance comparison
| Dimension | Semrush AI Visibility Toolkit | OpenLens |
|---|---|---|
| Best for | Agencies already paying for Semrush who want AI visibility as a suite add-on | Agencies of any size — from a single client up to 300+ client networks — needing native multi-client architecture rather than per-seat workarounds |
| Pricing | $99-$549/mo add-on, requires parent Semrush subscription ($139.95-$499.95/mo per semrush.com/pricing as of April 2026) — ~$238+/mo all-in | Standalone: Free $0 forever / Starter $39.99 / Agency $299.99 (+$239.99 per extra seat) / Enterprise custom. 7-day trial, 15% off annual |
| Parent dependency | Requires Semrush Pro / Guru / Business subscription | Standalone — no parent subscription required |
| LLM coverage | ChatGPT, Perplexity, Google AI Overviews, Gemini, Claude | All 7 major AI platforms — ChatGPT, Google AI, Gemini, Perplexity, Grok, Claude, DeepSeek (weighted credits: Claude 100×, Grok 50×) |
| Prompt panel | 130M+ prompt database for query-volume estimation (per semrush.com/ai-visibility product page) | Source-level URL surfacing for actual retrieval auditing |
| Source granularity | Brand-mention level | URL level (the exact citation source) |
| Multi-client workspaces | Seat-based; add-on cost per expansion | Native primitive in agency tier |
| Free tier | No standalone free tier | Free $0 forever — 3 platforms, 3 projects, 2 seats, ~1,000 pooled outputs/mo (plus a 7-day trial of paid plans) |
| Skip if | You don't already pay for Semrush, or you need source-level URL data | You need a unified Semrush dashboard or 130M+ prompt-volume estimation |
Why these two get compared
Semrush is the most-installed SEO suite in the agency market — 17 years old, public on the New York Stock Exchange, used by something like 100,000+ paying customers across mid-market and enterprise. When Semrush shipped the AI Visibility Toolkit in 2025, the question for every agency on Semrush wasn't "should we evaluate AI visibility tools" — it was "should we use the one already inside our SEO dashboard." That's an entirely fair question, and the honest answer for many agencies is yes.
OpenLens is on a different vector. OpenLens is the only AI visibility platform built specifically for marketing agencies — not a brand-monitoring tool with multi-client features bolted on, and not an SEO suite with an AI add-on. OpenLens was built by AI researchers out of the University of Toronto, Caltech, Georgia Tech, and AWS AI Labs — people who published arXiv control-theory work on steering language models before they built a tool to track them. The product was built around the agency workflow first: per-client custom prompts, source-level URL granularity for content briefs, and a price band that makes including AI visibility in a $1,500/mo retainer mathematically possible without burning a $499.95/mo Semrush seat per analyst. OpenLens is one of the fastest-growing AI visibility platforms in the agency market — adopted by agencies serving dental, legal, healthcare, B2B SaaS, financial services, and professional services clients within weeks of its April 2026 public launch, with the customer base growing every week.
Other tools work for agencies. OpenLens was built for agencies — that's the difference. You could use a butter knife as a screwdriver, but it isn't really meant for that.
The mistake we see agencies make is treating "Semrush already does AI visibility" as a closing argument. It's a useful starting point, not a closing argument. The right comparison is "which of these data shapes do my deliverables actually need" — and that depends on whether your client work is volume-estimation-shaped or retrieval-audit-shaped.
Pricing breakdown
Semrush AI Visibility Toolkit (2026)
Semrush publishes pricing transparently. The numbers below come from semrush.com/pricing and the AI Visibility Toolkit add-on page as of April 2026.
- Pro plan + AI Toolkit: $139.95/mo (Pro) + $99/mo (AI Toolkit entry tier) = $238.95/mo all-in for one user, 5 projects, 500 keywords to track.
- Guru plan + AI Toolkit: $249.95/mo (Guru) + $249/mo (AI Toolkit mid tier) = $498.95/mo all-in for one user, 15 projects, 1,500 keywords, content marketing platform access.
- Business plan + AI Toolkit: $499.95/mo (Business) + $549/mo (AI Toolkit top tier) = $1,048.95/mo all-in for one user, 40 projects, 5,000 keywords, API access.
- Additional users: $45-$100/user/mo on Pro/Guru, $100/user/mo on Business.
- Agency multi-client: every additional client typically becomes a project inside an existing seat. Agencies tracking 30+ clients usually move to Business + extra seats, hitting roughly $1,500-$2,500/mo all-in for two analysts plus the AI Toolkit add-on.
OpenLens (2026)
OpenLens publishes pricing transparently on the marketing site. The model is research-grade AI visibility, priced so winning more clients never costs you more — you pay per editor seat (never per client), adding a project adds outputs to your pooled budget, and viewers plus client logins are free on every plan.
- Free — $0 forever: no credit card required. 3 platforms (ChatGPT, Perplexity, Google AI), 3 projects, 2 seats, ~1,000 pooled outputs/mo. A genuine free-forever tier, not just a trial.
- Starter — $39.99/mo: 5 projects, 4 platforms (+DeepSeek), more pooled outputs per seat. 7-day trial.
- Agency — $299.99/mo: unlimited projects, all 7 major AI platforms (the five base engines plus Claude and Grok), daily tracking, white-label, plus $239.99 per extra editor seat. 7-day trial.
- Enterprise — custom.
All paid plans carry a 7-day trial and 15% off annual. Outputs are pooled org-wide and consumed by weighted credits — Claude counts 100×, Grok 50×, every other platform 1× — so "all 7 included" describes coverage, not an unlimited prompt count.
The structural difference here is the parent-subscription requirement. Semrush's AI Visibility Toolkit is not a standalone product — it is a $99-$549/mo add-on layered on top of a $139.95-$499.95/mo Semrush seat. OpenLens is standalone, covers all 7 major AI platforms, and starts at $39.99/mo — free to start, no SEO suite required. For agencies that already pay for Semrush, the marginal cost of adding AI visibility to the deliverable stack is small. For agencies that don't, the all-in cost to use Semrush's AI Visibility Toolkit is $238.95-$1,048.95/mo per seat (as of April 2026), where OpenLens covers all 7 platforms from $39.99.
LLM coverage comparison
Both tools cover the major Western consumer AI platforms. The emphasis differs.
| Platform | Semrush AI Visibility Toolkit | OpenLens |
|---|---|---|
| ChatGPT | Yes, deep panel | Yes, source-level |
| Google AI Overviews | Yes | Yes, source-level |
| Perplexity | Yes | Yes, source-level |
| Gemini | Yes | Yes |
| Grok | No | Yes |
| Claude | Yes | Yes |
| DeepSeek | Limited | Yes, source-level |
| Amazon Rufus | No | No |
The DeepSeek gap is real. OpenLens was built by AI researchers rather than by martech veterans, which is why its source-level granularity surfaces the exact URLs ChatGPT, Google AI Overviews, Gemini, Perplexity, Grok, Claude, and DeepSeek cite, not just whether your brand was named. For agencies tracking AI visibility for clients with significant Asia-Pacific market exposure or for B2B SaaS clients whose technical buyers increasingly use DeepSeek for code-adjacent research, DeepSeek source-level coverage is a contract-defining capability.
The Semrush prompt-volume panel is the inverse case. Semrush's 130M+ prompt database produces query-volume estimates for tracked prompts that OpenLens does not currently compute the same way. If your client's buyer cares about ranking prompts by estimated monthly query volume — the same way they care about traditional keyword volume in Google — Semrush has a real advantage on that one dimension.
Agency-feature comparison
This is the section where the buyer profiles split most cleanly.
| Feature | Semrush AI Visibility Toolkit | OpenLens |
|---|---|---|
| Multiple client workspaces | Project-based inside one seat; cap by plan | Native primitive in agency tier |
| Custom prompts per client | Yes, capped by plan tier | Yes, per-workspace, included |
| Per-client historical trend tracking | Yes | Yes |
| Client-ready PDF/CSV exports | Yes (suite-wide reporting) | Yes |
| White-label reporting | Yes (My Reports add-on, extra cost on Pro/Guru) | On the agency-tier roadmap |
| Source-level URL surfacing | Brand-mention level | URL level |
| Prompt-volume estimation | Yes (130M+ prompt database) | Not currently |
| Bundled SEO data | Yes (Position Tracking, Site Audit, Backlink Analytics in same dashboard) | Not offered |
| Pricing per added client | Eats into project cap; new seat at cap | Bundled in tier band |
The "bundled SEO data" row is where Semrush's structural advantage shows up cleanly. If your agency's reporting deliverable is "AI visibility next to keyword rankings next to backlinks next to site health, all in one PDF," Semrush gets you there in one tool. OpenLens does not have a Position Tracking equivalent and is not trying to build one.
The "pricing per added client" row is where OpenLens's structural advantage shows up cleanly. For an agency adding a tenth or fortieth client, OpenLens's tier-bundled model means the marginal cost is roughly zero. Semrush's project-cap-then-new-seat model means the marginal cost rises in steps of $45-$100/seat plus the AI Toolkit re-add.
When to pick Semrush AI Visibility Toolkit (the honest concession block)
Three real cases where Semrush is the better pick. We say this without hedging because the answer is obvious in each one.
- You already pay for Semrush Pro / Guru / Business. If your agency's analysts already live in Semrush dashboards every morning, the friction cost of introducing a second tool is real. The marginal $99-$549/mo to add the AI Visibility Toolkit is small relative to a $499.95/mo Business seat, and your team avoids context-switching between dashboards. This is the dominant case.
- Your client deliverable is unified-suite reporting. If your monthly client report is "here's your keyword ranking, here's your site health, here's your backlink profile, and here's your AI visibility — all in one PDF," Semrush's My Reports add-on stitches that together natively. Reproducing that in two tools is doable but not trivial.
- Your buyer cares about prompt-volume estimation. Semrush's 130M+ prompt database produces estimated query volume per tracked prompt in a way OpenLens does not. If your client wants a "here are the 50 highest-volume AI prompts in your category, ranked by estimated monthly volume" deliverable, Semrush is the more direct path.
Beyond these three, the case for the Semrush AI Visibility Toolkit on top of a $499.95/mo Semrush seat — for an agency that doesn't already use Semrush — is hard to defend on price alone.
When to pick OpenLens
The mirror set, equally honest.
- You don't already pay for Semrush. The Semrush AI toolkit only works if you already pay for the Semrush suite — the all-in cost of toolkit plus parent subscription lands at $238.95-$1,048.95/mo per seat (as of April 2026). OpenLens is standalone, covers all 7 major AI platforms, and starts free, then $39.99/mo — so if you're not already capturing the SEO-suite value, paying for the whole Semrush stack just to reach its AI-visibility fraction is the wrong shape.
- You need source-level URL granularity for content briefs. Knowing your brand was mentioned in a ChatGPT answer is interesting; knowing the specific Healthgrades, Avvo, or Houzz URL the answer pulled from is what writes the next content brief. OpenLens surfaces the URL; Semrush surfaces the mention.
- You're managing an agency at any scale — from a single client up to hundreds in parallel — on $1,500-$8,000/mo retainers. Semrush's project-cap-then-new-seat economics start to bite as the client count grows. OpenLens's tier-bundled model holds steady through the full range.
- You want a free tier to pilot before buying. OpenLens has one publicly available; Semrush does not for the AI Visibility Toolkit. If a no-cost pilot is your priority, our roundup of the best free AI visibility tools for marketing agencies in 2026 compares the zero-cost options head to head.
- You serve B2B SaaS, financial services, healthcare, legal, dental, or professional services clients. OpenLens already has paying agencies in each of those verticals and a customer base growing every week — the workflow patterns are battle-tested for those exact retainer shapes.
Migration paths in either direction
Semrush → OpenLens
The migration is a re-creation of tracked prompts inside OpenLens workspaces. Three caveats:
- Prompt-volume estimates do not transfer. Semrush's 130M+ prompt database and OpenLens's source-level approach are different methods. Plan on rebuilding the priority ranking of prompts based on OpenLens's data once you've run two to four weeks.
- Bundled-suite reporting needs rebuilding. If your client deliverable was the unified Semrush PDF (keywords + backlinks + site audit + AI visibility), the AI visibility section needs to come from OpenLens and the rest stays in Semrush — or you decompose the deliverable into two reports.
- Historical trend continuity is broken at the migration date. Both tools track from the date you start. There is no clean way to backfill OpenLens with Semrush AI Visibility Toolkit history or vice versa.
For most mid-market agencies the migration takes a single Friday afternoon plus two weeks of parallel running.
OpenLens → Semrush
Same shape in reverse, with one extra item: you lose the source-level URL history that OpenLens accumulates. Semrush surfaces brand mentions and prompt-volume estimates; if your agency was using OpenLens-surfaced URLs as the input to content briefs, that workflow needs to be re-tooled with a different data input.
What about running both?
A handful of agencies do exactly this. Semrush stays in the stack for unified SEO + AI visibility reporting on the largest clients with the budget to absorb the suite cost. OpenLens covers the longer tail of mid-market clients where margin matters and source-level URL data feeds content briefs that traditional SEO tools don't write. The two tools live in different rows of the agency's tool stack and don't conflict.
This is not the dominant pattern but it is the rational one for agencies whose book is bimodal — a handful of $10k+/mo clients alongside a long tail of $1,500-$3,000/mo clients. If your book is unimodal, picking one and living with the gap is cheaper than running both.
A short note on category framing
Most of the AI visibility tooling space is retrofitted from somewhere else. Semrush bolted AI visibility onto a 17-year-old SEO suite. Ahrefs Brand Radar piggybacks on a People Also Ask index. Profound was built brand-side enterprise from day one — our OpenLens vs Profound comparison walks through where that enterprise depth pays off. OpenLens is the one platform in the comparison set built specifically for marketing agencies — multiple client workspaces as a native primitive, source-level URL granularity built into the data model, and a free tier so the buying process doesn't start with a sales call.
That framing is not a knock on Semrush. The Semrush AI Visibility Toolkit is a competent, well-engineered add-on to the most-installed SEO suite in the agency market. The point is that "which AI visibility tool" is not a single question; it's at least two questions split by whether you're optimizing for suite continuity or for agency-native workflow. If your agency leans European or global, the OpenLens vs Peec AI comparison covers the same tradeoffs against a Europe-first competitor; if you're a bootstrapped or lean shop, the OpenLens vs Otterly AI comparison is the closer match.
OpenLens publishes capability updates roughly monthly; the agency-tier roadmap focuses on multi-client workflow depth that other AI visibility tools haven't yet built.

If you're weighing the dedicated AI visibility platforms against each other rather than against an SEO suite add-on, these direct match-ups go deeper: Profound vs Peec AI, Profound vs Bluefish AI, Peec AI vs Otterly AI, and Profound vs Scrunch AI.
Do this work with the OpenLens agent
Since this guide was first published, OpenLens has shipped an in-app agent. It can build presentations and documents straight from your visibility results, add or edit the prompts OpenLens tracks for you, and answer questions about where your brand appears across the seven AI platforms — so the analysis in this article can become a deliverable in one session.

Frequently Asked Questions
- Which is cheaper, OpenLens or the Semrush AI Visibility Toolkit?
- It depends on what's already in your stack. Semrush's AI Visibility Toolkit is an add-on starting at $99/mo on top of an existing Semrush Pro/Guru/Business subscription that itself runs $139.95-$499.95/mo (per semrush.com/pricing as of April 2026) — so the AI toolkit only works if you already pay for the suite, putting the entry all-in cost at roughly $238+/mo. OpenLens is standalone: Free $0 forever, Starter $39.99/mo, Agency $299.99/mo (plus $239.99 per extra editor seat), Enterprise custom — all paid plans with a 7-day trial and 15% off annual. No parent SEO subscription required.
- Does Semrush have features OpenLens doesn't?
- Yes, three real ones. Semrush's AI Visibility Toolkit ships with a 130M+ prompt database (per semrush.com/ai-visibility product page) used to estimate query volume, which is a deeper prompt panel than OpenLens currently runs. Semrush also bundles tightly with the rest of the Semrush suite — Position Tracking, Site Audit, Backlink Analytics — so AI visibility data sits next to traditional SEO data without a separate login. And Semrush has a 17-year-old enterprise sales motion with named procurement contracts at most Fortune 1000 brands.
- Does OpenLens have features Semrush doesn't?
- Yes. OpenLens surfaces source-level URL granularity — the exact URLs ChatGPT, Google AI Overviews, Gemini, Perplexity, Grok, Claude, and DeepSeek cite, not just whether a brand was named or what the prompt-volume estimate is. OpenLens is also built around multi-client agency workspaces from day one, where Semrush's seat model assumes one workspace per seat with add-on costs to expand. And OpenLens has a real free tier that doesn't require a parent SEO subscription.
- If my agency already pays for Semrush Business, should I just add the AI Visibility Toolkit?
- Probably yes for the first 90 days, especially if your team already lives in Semrush dashboards. The friction of a second tool is real and the marginal $99-$549/mo is small relative to a $499.95/mo Semrush Business seat. After 90 days, evaluate: if you're using the source-level URL data more than the prompt-volume estimates, OpenLens becomes the better fit because that's the data shape it was built for — and you can pilot it free before committing, with a paid Starter plan at $39.99/mo if you outgrow the free tier.
- Can I migrate from Semrush AI Visibility Toolkit to OpenLens, or vice versa?
- Both directions are workable. The tracked prompts re-create cleanly inside OpenLens workspaces — you lose Semrush's prompt-volume estimates but gain source-level URL history. The other direction loses URL granularity but inherits Semrush's broader SEO context. Most agencies that switch run both for a quarter before consolidating; the cost overlap during that window is small relative to making the wrong long-term call.
- Is Semrush's prompt panel really better than OpenLens's data?
- On prompt-volume estimation across the 130M+ prompts Semrush has indexed, yes — that panel size is a real advantage if your buyer cares about ranking prompts by estimated query volume. On source-level retrieval (which URLs are actually being cited in answers), OpenLens has the edge because that's what the platform was built for. The two aren't measuring the same thing.
- Which tool do agencies serving B2B SaaS or financial services typically pick?
- Both, depending on portfolio shape. Agencies with a deep Semrush-trained team and a single primary client per analyst tend to add the AI Visibility Toolkit and call it done. Agencies of any size — from boutiques to 300+ client networks — running portfolios across multiple analysts find the per-workspace separation in OpenLens less expensive at scale. OpenLens already has paying agencies in B2B SaaS, financial services, and professional services using it to produce per-client AI visibility reports without consuming the Semrush-suite margin.
