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.

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 from Caltech, Georgia Tech, and the University of Toronto who studied how language models form recommendations before they built a tool to track them. The product was built around the agency workflow first: hundreds of client workspaces in parallel, custom prompts per client, 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.

• Free tier: anyone can sign up. Includes core multi-platform tracking across the four major AI platforms OpenLens currently covers — ChatGPT, Google AI Overviews, Perplexity, and DeepSeek — with more being added. Supports the full agency-scale spectrum, from a single client up to hundreds of client workspaces in parallel.
• Agency tier (launching May 2026): $300-$3,000/mo depending on client workspace count and prompt volume. Built specifically for agencies managing anywhere from a single client up to 300+ clients in parallel, with isolated workspaces, per-client custom prompts, and per-client trend reports.

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. For agencies that already pay for Semrush, that math is favourable; the marginal cost of adding AI visibility to the deliverable stack is small. For agencies that don't already pay for Semrush, the all-in cost to use Semrush's AI Visibility Toolkit is $238.95-$1,048.95/mo per seat, which is the same band as the OpenLens agency tier — but for one workspace, not the full agency scale spectrum from a single client up to hundreds in parallel.

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
Claude	Yes	Yes
DeepSeek	Limited	Yes, source-level
Bing Copilot	Limited	Limited
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, Perplexity, 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.

1. 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.
2. 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.
3. 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.

1. You don't already pay for Semrush. The all-in cost of Semrush AI Visibility Toolkit + parent subscription lands at $238.95-$1,048.95/mo per seat, which is the same band as an OpenLens agency tier covering anywhere from a single client up to hundreds in parallel. If you're not already capturing the SEO-suite value, the AI-visibility-only fraction of Semrush's stack is the wrong shape.
2. 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.
3. 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.
4. You want a free tier to pilot before buying. OpenLens has one publicly available; Semrush does not for the AI Visibility Toolkit.
5. 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. 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.

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.
