The short answer
The API and the MCP server are open on the free plan, so your own agent can drive it.
2PassciteThis is us
Three engines and a named competitor on every prompt, free on an account with no card. One report, on one brand.
The only score here that shows its working — four components, each traceable to a check you can look at.
Zero friction — the only check here you can run without giving anything at all.
On this page
Six criteria, fixed before scoring
- 01
What it asks for first
The difference between a tool you can run on a prospect mid-call and one you cannot. An account is more friction than an email, an email is more than nothing, and a card disqualifies a thing from being called free.
- 02
Engines it queries
One engine is one engine's mood. Assistants disagree with each other constantly on exactly the comparative questions buyers ask, so a single-engine check can tell you the opposite of what a second one would.
- 03
How many questions
Five probes can tell you a site is invisible. They cannot tell you which of your client's services is the one losing, which is the answer that makes anybody act.
- 04
A score, or a named competitor
A number out of 100 is easy to put in a deck and impossible to act on. Naming the competitor that won a specific question, and the page of theirs that got cited, is the part an agency argues with a client about and then fixes. Scores are genuinely better for watching movement over months — these free checks are not that.
- 05
Can you run it again
One run on one domain is a demo. An agency looking at a roster needs to run the same check on the next prospect next week.
- 06
What the free run is selling
Every one of these exists to sell something, ours included. What matters is whether the free output is useful on its own if you never buy anything.

The order is a judgement on the question this page asks, not a count of the marks; the questions at the end argue it.
Each tool, checked and dated
- 1
Rank Prompt
One free report on a new account (10 credits). Account required, no card.
The first report on their tracking product, free with an account: up to three brands, with the API and MCP server open on the free plan.
Partly01What it asks for first
An account, no card. More friction than an email, less than their paid trial, which takes a card.
Meets it02Engines it queries
ChatGPT, Google AI Mode and Claude on the free report, by their pricing page; another of their pages says all six. The paid tiers reach six.
Meets it03How many questions
Ten credits, which their pricing page says is exactly one report; their quickstart starts with nine prompts.
Meets it04A score, or a named competitor
Per prompt, whether you were named, which brands were named instead and the sources, with a Prompts they win tab — and a visibility score on top.
Partly05Can you run it again
One report's worth of credits. Scheduling it weekly is free to set up, but every run draws credits, which the free plan can buy as top-ups — $18 for 50.
Partly06What the free run is selling
The first run of a credit-metered tracker; the next step is a paid plan's seven-day trial, which takes a card. The report is still a real reading on its own.
Wins
- The API and the MCP server are open on the free plan, so your own agent can drive it.
- Three brands set up on the free account, ready for the day you pay.
- No card for the free report; the card only comes with a paid plan's trial.
- Six engines once you pay, as many as anything on this page.
Pick it for
Trying a credit-metered tracker on one prospect before buying a plan, especially if you want to drive it from your own agent over MCP.

Passcite
This is usFree account: 10 credits, once. Google or an emailed code, no card.
The first report on a free account: 10 prompts across ChatGPT, Claude and Google AI Mode on one brand, who was named on each, and the tasks it suggests.
Partly01What it asks for first
An account — Google or an emailed code — and no card, the same as Rank Prompt's. overrank's checker asks for nothing at all.
Meets it02Engines it queries
Three — ChatGPT, Claude and Google AI Mode — on the free report, and Gemini, Perplexity and Grok for two credits a prompt.
Meets it03How many questions
10 prompts suggested from the site, of the kinds a buyer types — the best one for a need, one against another, what it costs — which you can change before the report runs.
Meets it04A score, or a named competitor
Every prompt comes back with who was named on each engine and the pages the engines cited, and the report suggests tasks from what the site does not answer.
Misses it05Can you run it again
One report's worth of credits. Running it again, or on a second brand, takes a plan — 7 days free with 50 credits, card required — and top-ups come only with a plan.
Partly06What the free run is selling
The first run of a credit-metered tracker, as on Rank Prompt; the next step is a plan's seven-day trial, which takes a card. The report and its tasks are a real reading on their own.
Wins
- Three engines on the free report, where most free checks query one.
- Named competitors per prompt, with the pages cited, instead of a number out of 100.
- The tasks come with the free report: the pages to write, and the listings and site files to fix.
- 11 free tools alongside it that need no email whatsoever.
Loses
- What the free account holds: Rank Prompt's holds three brands, opens its API and MCP server to your own agent, and sells top-ups. Ours holds one brand, opens its MCP server but has no API, and sells top-ups only with a plan.
- Friction: overrank's checker asks for nothing, not even an email. Ours asks you to sign in.
- Running it again: overrank's checker runs five times a day, and Rank Prompt's free plan can buy more credits. Ours is one report until you start a plan.
- Deliverables: Rank Prompt exports PDF and PowerPoint on its paid plans. Ours is a shared link, printed to PDF from the browser; there is no export file.
Pick it for
One business you are about to work on, where you want to see which prompts it loses and to whom before choosing a plan.

Foliora
Free. Email, no card. One run on one domain.
A findability score out of 100 built from four readings, two sampled from outside and two read off your own pages.
Partly01What it asks for first
Email confirmation before the full snapshot runs. No card, no sales call — stated plainly on the page.
Partly02Engines it queries
ChatGPT and Gemini.
Partly03How many questions
A fixed question panel plus your category phrases against Google. The count is not published.
Partly04A score, or a named competitor
A score out of 100 — but an unusually honest one: 30 points found in Google, 30 cited by AI, 20 offer-page strength, 20 buyer coverage, every point traceable to a dated check, and it names who is cited in your place.
Misses it05Can you run it again
One free run on one domain. It is a preview of the paid loop, and says so.
Partly06What the free run is selling
It is the front door to a $49.99-per-site product, and the score is designed to make the gap visible. That is fair, and it is still a real reading.
Wins
- The only score here that shows its working — four components, each traceable to a check you can look at.
- Names who is being cited instead of you, which most scored checks do not.
- "Unsampled ≠ absent" is printed on their own page, which is a more careful claim than anything else in this category makes.
- Reads only public pages and never signs in, stated up front.
Pick it for
One store or site you are about to work on, when a single defensible number is what the person paying wants to see.

overrank
Free. Nothing asked at all. Five checks a day per browser.
A 0-100 visibility score from five representative queries, with three suggested actions.
Meets it01What it asks for first
Nothing. No email, no account, no card — five checks per day per browser. The lowest friction on this page by a clear margin.
Misses it02Engines it queries
Claude only. The page names ChatGPT, Claude, Perplexity and AI Overviews in its pitch, then says it probes Claude with five questions.
Partly03How many questions
Five queries, generated from your brand context. Enough to tell you that you are invisible, not which service is losing.
Misses it04A score, or a named competitor
A 0-100 score plus three actions. No named competitor and no cited page.
Meets it05Can you run it again
Five a day per browser, no sign-in. You can run it on a list of prospects in one sitting.
Misses it06What the free run is selling
The page labels the tool "1 of 30+ things overrank automates" and the next call to action is a free SEO audit of your site. The check is the top of a funnel more than a deliverable.
Wins
- Zero friction — the only check here you can run without giving anything at all.
- Five a day, so a whole prospect list can be swept in one sitting.
- Fast, and honest about what it does: five queries, one engine, a score.
- Sits inside a 16-tool free matrix that is genuinely useful on its own.
Pick it for
A quick triage sweep across a list of prospects, to find which ones are worth running a real check on.

What this page leaves out, and why
Semrush's free AI search visibility checker
It exists at semrush.com/free-tools/ai-search-visibility-checker and we did not run it on 15 Sept 2026, so it is not scored here. Semrush's paid AI visibility is ranked on the Semrush and Ahrefs page instead.

Geoa's free scan
Five questions with no commitment, per their pricing page. The terms around it are published only in Danish and we did not want to score a free tier off a translation.
Checked 15 Sept 2026
ChatSEO
Five free prompts with no card, but they go to an SEO agent that works from Search Console; nothing we read on chatseo.app says it checks what an AI assistant answers about a site.
Checked 1 Oct 2026
Profound, Peec, Scrunch
Enterprise trackers. Where a free look exists at all it is a demo booked through a sales call, which is a different thing from a check you can run yourself.

Questions
- Why is Rank Prompt first, when its free report looks like yours?
- Because the free reports are the same shape — an account, no card, ten credits, three engines — and Rank Prompt's account gives more around it: three brands, its API, and top-ups without a plan. Ours holds one brand with the MCP server open, and the next run takes a plan.
- What is wrong with a visibility score?
- Nothing, for watching movement over months, which is what the tools that sell scores are actually for. It is the wrong output for a one-off free check, because a client cannot act on 41/100 and can act on knowing that their competitor's comparison page won the prompt their buyers ask most.
- Why does yours need an account when overrank's needs nothing?
- Because a report that asks three engines 10 prompts costs us real money per run, and the free credits are given once per account. It is a genuine cost of the depth, but it is still more friction than asking for nothing.
- Can I run a free check on a client before pitching them?
- Yes, on every tool here, and none of them requires the client's permission because all of them read only public pages. Whether to tell the client you did is a question about your relationship, not about the tool.
- One-to-one comparisonsSemrush, Ahrefs, Surfer SEO, Foliora, overrank, Rank Prompt and Otterly.AI, one at a time, with where each is stronger first.
