Free ChatGPT visibility tools: every genuinely-free option in 2026, compared

Most "free ChatGPT visibility tools" in 2026 are one-time lead-gen scans dressed up as monitoring. A few are genuinely free, and exactly one gives you free ongoing tracking. This guide compares every real free option — free-forever trackers, free one-time graders, free trials on the paid platforms, the SolCrys free audit, and DIY scripts — and is honest about the measurement-fidelity traps (mini-models, snapshot under-counting, single-run noise) that make some "free checks" misleading.

Direct answer

There are real free ways to check your brand's visibility in ChatGPT in 2026, but they split into three groups that do genuinely different jobs — and most articles blur them together. Sort by the job first, pick the tool second.

Disclosure up front: SolCrys publishes this guide and our own free audit is one of the options below. We are not a neutral source. We have written it the way we wish other "free tools" lists were written — honest about which tools are free-forever, which are one-time lead-gen scans, and which are trials with a meter running — and honest about where the numbers are trustworthy and where they aren't. Pricing and coverage are drawn from each vendor's public 2026 pages and dated third-party reviews; treat them as orientation, not quotes.

Free-forever ongoing tracking — exactly one tool does this today: Trakkr has a free tier that tracks one brand across eight engines on a daily cadence. Everything else "free" is a one-shot.
Free one-time graders and checkers — HubSpot's AEO Grader, Ahrefs and Semrush AI-visibility checkers, Mangools' grader, Omnia, and the SolCrys free audit. One scan, one report, no recurring monitoring.
Free trials on paid platforms — Peec AI, Otterly, Knowatoa, Rankscale, Scrunch all offer time-boxed trials. Functional for evaluation; they expire by design.
Manual spot-checks and DIY scripts — open ChatGPT and prompt it yourself, or script the OpenAI API. Free in license cost; expensive in time and easy to get wrong.

The one distinction that decides everything: tracker vs grader vs trial

"Free ChatGPT visibility tool" is three products wearing one label. Get this right and the rest of the page is easy.

A tracker runs a fixed prompt set on a schedule and shows you a line moving over time. A grader runs once and hands you a snapshot score. A trial is a full paid tracker with an expiry date attached. The mistake teams make is treating a grader's one-time score as if it were a tracker's baseline — then wondering why they can't see whether anything changed. A single ChatGPT check is one sample of a moving target, not a measurement.

If you only remember one thing: a one-time grade tells you whether AI visibility is a problem worth caring about; only a tracker tells you whether your work is fixing it.

Every genuinely-free option, compared

These are the tools with a real free path (not just a trial). The last column is the one most listicles omit — what the free tier actually does under the hood, and where that limits the number you get back.

Coverage and mechanism are from each vendor's public 2026 product pages, observed 2026-06-03. Engine lists change often; re-check before you rely on one.

Tool	What's genuinely free	Engines (free tier)	How it gets ChatGPT data	Signup	Honest caveat
Trakkr	Free-forever — ongoing daily tracking	ChatGPT + 7 others (Claude, Gemini, Perplexity, Grok, DeepSeek, Copilot, Meta AI)	Live multi-model querying, daily	Account, no card	One brand only; history depth and competitor sets are paid (plans from $79/mo)
SolCrys free audit	One-time structured audit	ChatGPT	10 buyer prompts run through ChatGPT; parsed for mention rate, share of voice, cited sources, sentiment	Email-verify, no card	One-shot snapshot, ChatGPT only; daily and multi-engine tracking are paid
HubSpot AEO Grader	One-time grade, unlimited runs	ChatGPT, Perplexity, Gemini	Queries a smaller model tier and characterizes from training data, not live ChatGPT Search	None	A mini-model, training-data view is not the live ChatGPT answer a buyer actually sees
Ahrefs AI Visibility Checker	One-time preview	ChatGPT, Perplexity, Gemini, Copilot, AI Overviews, AI Mode	Search-backed prompt snapshots — not live ChatGPT querying	None	Strong for Google AI Overviews; the snapshot method can badly under-count live ChatGPT mentions (see below)
Semrush AI Visibility Checker	One-time scan	ChatGPT, AI Overviews, Gemini	Runs industry-relevant prompts across LLMs for a 0–100 score	None	One-time; funnels to the $99/mo AI Visibility Toolkit for tracking
Mangools AI Search Grader	One-time grade	3 engines without an account; 8 with a free account	Runs each prompt about 5 times for an averaged score	Free account for full coverage	Grader is one-time; ongoing watcher starts around $15.60/mo (annual)
Omnia AI Visibility Checker	One-time report	ChatGPT, Perplexity, AI Overviews, AI Mode	Domain scan, results emailed	Email	Report-by-email, not an interactive dashboard

Free-forever ongoing tracking — the category of one

If you want a free line that moves over time, not a one-off score, there is currently a single credible option.

Trakkr offers a free-forever tier that tracks one brand across eight engines — ChatGPT, Claude, Gemini, Perplexity, Grok, DeepSeek, Copilot, and Meta AI — on a daily cadence, with the first scan in a couple of minutes. It is genuinely useful as a permanent "are we in the conversation?" monitor for a single brand. The limits are deliberate: one brand, shallow history, and competitor sets gated behind the paid plans (from $79/mo, as listed on trakkr.ai, observed 2026-06-03). For a solo founder or a one-product startup, the free tier is a legitimate standing instrument — not a trial countdown.

Free one-time graders and checkers — useful, with sharp edges

These are the "paste your domain, get a score" tools. They are real and they are free, but each one is a lead magnet for a paid product, and the free number carries a fidelity caveat you should know before you quote it in a deck.

SolCrys free audit — the structured ChatGPT one

Our free audit runs 10 buyer-intent prompts through ChatGPT, parses each answer for brand mentions (yours and competitors) and the cited source URLs, and returns one report with mention rate, competitor share of voice, the top citation sources, and sentiment — in about five minutes, email-verified, no card. It is designed as an honest first read on whether AI search is a real channel for your category, not a stripped-down demo. What it does not do for free: Gemini, Perplexity, and Google AI Overviews, custom prompts, daily tracking, alerts, or the action layer. Run it →

HubSpot AEO Grader — the best truly-free one-time check

HubSpot's AEO Grader is the most generous free one-time tool: unlimited runs, no signup, no card, and it actually queries the models rather than guessing. The honest caveat is the mechanism — it queries a smaller, cheaper model tier and characterizes your brand from training-time knowledge, not from a live ChatGPT Search answer with web citations. That makes it a good read on your base-model footprint and a poor read on what a buyer using ChatGPT Search sees today. HubSpot's continuously-monitoring AEO product is paid (around $50/mo, no HubSpot subscription required, as listed 2026-06-03).

Ahrefs and Semrush free checkers — watch the method

Both SEO incumbents ship a free AI-visibility checker as a funnel into their paid AI modules. Ahrefs' free checker (and its paid Brand Radar) are best-in-class for Google AI Overviews and AI Mode because they use real search-backed prompts — but that same snapshot method is the weak link for ChatGPT specifically. An independent 2026 comparison reported Brand Radar surfacing only 3 ChatGPT mentions for a brand that a manual count put at 123. Treat that as a single data point, not a verdict — but it is a sharp reminder that marketed coverage and actual capture rate diverge. Semrush's free AI Search Visibility Checker runs industry prompts across LLMs for a 0–100 score and funnels to its $99/mo Toolkit for ongoing tracking.

Mangools and Omnia — the lightweight options

Mangools' AI Search Grader covers three engines with no account and eight with a free account, and runs each prompt roughly five times for an averaged score — a small but real nod to the sampling problem most one-shot tools ignore. Its ongoing watcher is among the cheapest paid options in the category (from about $15.60/mo annual). Omnia's checker is a free domain scan that emails you a report; fine for a one-off, not built for repeat measurement.

Free trials on the paid platforms

Most paid AI-visibility platforms offer a trial. Trials are functional but calibrated to convert — usually a small prompt set, a subset of engines, or a time box. Use them when you are already in a buying cycle, not as an ongoing free tier. For the full paid comparison, see Best Tools to Track Brand Visibility in ChatGPT and Perplexity.

Platform	Free path	What to expect	Honest note
Peec AI	7-day trial, no card	Limited prompts on the full mid-market dashboard	EU-built, citation-URL extraction; from €89/mo after (as reported, 2026)
Otterly	Free trial, then cheap Lite tier	Per-prompt monitoring across ChatGPT, AI Mode, Perplexity, Gemini, Copilot	Cheapest paid entry (from $29/mo); per-prompt-per-engine quota burns fast
Knowatoa	7-day trial, no card	Daily question tracking with competitor benchmarking	From $59/mo; entry tier is ChatGPT + Google AI only, no Perplexity/Gemini
Rankscale	Free Pro trial	Credit-based multi-engine tracking (17+ engines)	From $20/mo; credit model makes real monthly cost hard to predict
Scrunch	7-day trial, no card	Multi-engine tracking, audits, persona prompts	Acquired by Sitecore (announced June 2026) — standalone pricing and roadmap may change
Profound	Sales-led demo only	Walkthrough of the enterprise platform	No self-serve free tier; enterprise-priced

Why "free" can mean "misleading" — the fidelity problem

The reason this page spends so long on mechanism is that a free number is only worth as much as the method behind it. Four traps make some free ChatGPT checks actively misleading, and almost no listicle names them.

None of these make the free tools useless. They make the free number something to read with the method in mind — which is exactly what a one-time grade can't tell you and a scheduled tracker can.

One run is a screenshot, not a measurement. ChatGPT answers are non-deterministic by design — sampling, periodic model updates, account personalization, and (in ChatGPT Search) a live-changing web all move the answer run to run. Ask the same question 20 times and your brand might appear in 12. A one-shot grader lands you on one point of that distribution and tells you it's the whole picture.
"Which ChatGPT?" matters. A brand can be visible in the base model (parametric memory, no citations) and invisible in ChatGPT Search (live retrieval over Bing's index plus OpenAI's own crawl, with cited URLs) — or the reverse. A free tool that quietly queries a mini-model or a base model is measuring a different thing than the ChatGPT Search answer your buyer sees.
Snapshot methods under-count live mentions. Tools built on static, search-backed prompt libraries (great for Google AI Overviews) can miss live ChatGPT mentions — the reported 3-vs-123 gap above is the cautionary case.
A single blended "AI visibility score" hides four different signals. Mention rate (are you named), citation rate (are your URLs the source), share of voice (your slice vs competitors), and sentiment (how you're described) are independent measurements with different fixes. Any tool — free or paid — that collapses them into one number is hiding where your actual problem is.

DIY: scripting your own check against the OpenAI API

Engineering-led teams can build a minimum tracker in under 100 lines. The OpenAI API call is the easy part; prompt-set curation, response parsing, and storage are the work. Two tradeoffs are worth stating plainly:

What you save: the license (roughly $300–$1,500/mo at the entry plans of the paid platforms).
What you absorb: API tokens (fractions of a cent per prompt), build time, ongoing prompt-set curation, and the parsing edge cases — ChatGPT names competitors with inconsistent spelling and embeds links in varied formats.
The non-obvious catch: the base OpenAI API is not the ChatGPT app. The app surfaces web citations and search behavior the default API call may not return, so a naive API script measures base-model mentions and misses the live ChatGPT Search citations that matter most.
Right use: engineering teams that want full control of prompts and storage and have an internal owner for maintenance. Wrong use: a marketing team that needs something live this quarter.

Which free path matches which job

The fastest way to your starting point: match the job to the path, not the other way round.

Job-to-be-done	Right free path	Why
I want a free line that keeps moving over time	Trakkr free-forever (1 brand)	The only genuinely free ongoing tracker today
I want a structured one-shot read on ChatGPT specifically	SolCrys free audit	10 prompts, mention + share of voice + citations + sentiment, 5 minutes
I want the most generous no-signup grade	HubSpot AEO Grader	Unlimited free runs — just remember it's a mini-model, training-data view
My priority is Google AI Overviews, ChatGPT second	Ahrefs free checker	Search-backed method is strong on Google AI, weaker on live ChatGPT
I'm already evaluating a paid platform to buy	That platform's trial	Trials are built for exactly this
I have engineering and want full prompt + storage control	DIY script	Maximum flexibility, real maintenance cost

When free stops being enough

Free tools answer one question well: "is AI visibility a real channel for my category?" They cannot answer the four that come next.

Is my mention rate trending up or down over the last 30 days, across engines?
Do Gemini and Perplexity rank a different competitor set than ChatGPT?
Which prompts am I losing share of voice on this week?
Which content investment would actually move the answer — and did it?

What paid tracking adds

The SolCrys Pro plan ($399/mo, as listed 2026-06-10) adds daily scans across ChatGPT, Gemini, Perplexity, Google AI Overviews, and Claude (any 4 of the 5) on prompts you control, alerting on drops, and the action layer that drafts content briefs against the prompts you're losing. That is the part free tools structurally can't reach: SolCrys closes the loop — Measure, Diagnose, Execute, Verify — by re-testing the same frozen prompt set after a fix and reporting whether the answer actually moved. Most tools, free and paid, stop at Measure. For the full paid field including SolCrys, Profound, Peec, Otterly, and Scrunch, see Best Tools to Track Brand Visibility in ChatGPT and Perplexity.

FAQ

Is there a genuinely free ongoing ChatGPT visibility tracker?

Yes, but only one as of mid-2026: Trakkr's free-forever tier tracks a single brand across eight engines (including ChatGPT) on a daily cadence, with no card required. Everything else marketed as a "free ChatGPT tool" is a one-time grade or a time-boxed trial. If you need more than one brand, history depth, or competitor sets, every platform — including Trakkr — moves you to paid.

What is the best free one-time ChatGPT visibility check?

Two stand out for different reasons. HubSpot's AEO Grader is the most generous — unlimited runs, no signup — but it queries a smaller model tier and characterizes from training data, so it reads your base-model footprint, not the live ChatGPT Search answer. The SolCrys free audit is the most structured for ChatGPT specifically: 10 buyer prompts returning mention rate, competitor share of voice, cited sources, and sentiment in about five minutes.

Do free ChatGPT visibility checkers actually query ChatGPT?

Some do, some approximate. Tools like the SolCrys audit and Trakkr send prompts to the model and read the answer. Others use a cheaper mini-model (HubSpot's grader), characterize from training data, or rely on static search-backed snapshots (Ahrefs) that can under-count live ChatGPT mentions. The mechanism matters: a base-model or snapshot view is not the same as the live ChatGPT Search answer a buyer sees, so always check what the free number is actually measuring.

Can I track my brand in Gemini and Perplexity for free too?

Partly. Trakkr's free tier and several free graders (Ahrefs, Mangools with a free account) include Gemini and Perplexity in their one-time or single-brand checks. But genuinely free, ongoing, multi-engine tracking on a custom prompt set does not really exist in 2026 — running daily scans across five engines has real API and infrastructure cost, which is the structural reason the paid plans exist.

Are manual ChatGPT spot-checks a substitute for a tracker?

For a one-off qualitative gut-check, yes. For measurement, no. Manual checks can't average cross-session variance, miss roughly half the competitor mentions on a careful human reading, and don't aggregate over time. The structured part of a real tracker — a fixed prompt set, consistent timing, and mention parsing — is what makes the numbers comparable enough to act on.

Can I just script this against the OpenAI API myself?

If you have engineering capacity and an owner for maintenance, yes. The hard parts are curating a buyer-intent prompt set, parsing inconsistent brand mentions and link formats out of responses, and storage. One catch trips most teams: the base OpenAI API is not the ChatGPT app — it may not return the web citations and search behavior that make ChatGPT Search visibility meaningful — so a naive script measures the base model and misses the surface buyers actually use.
