Key takeaways
- Almost every "free" ChatGPT rank tracker is one of three things: a one-shot checker with no history, a time-boxed trial, or a tiny capped free tier.
- ChatGPT answers vary from run to run, so a single manual check is an anecdote, not data. Real tracking means running the same prompts repeatedly and averaging.
- The best free starting points in 2026 are one-off checkers (HubSpot AEO Grader, Semrush, Profound's report) for a baseline, and no-card trials (Otterly.AI, Morningscore, ProRankTracker) for trend data.
- Free runs out fast. ChatGPT cites roughly 5 sources per web-search answer, so the pool you are measuring is small and noisy.
- Vendor "best of" lists rank themselves first. Treat accuracy claims and rankings from tracker vendors as unverified, and check trial lengths and prices on the vendor's own page.
What "free" actually means in ChatGPT rank tracking
I have looked at a lot of these tools, and the word "free" is doing heavy lifting. A ChatGPT rank tracker is not like a Google rank tracker. There is no position 1 to 10. ChatGPT builds one answer, names a few brands, and cites a handful of sources. So these tools run your prompts through ChatGPT on a schedule and log mentions, citations, position within the answer, sentiment, and share of voice.
Running that on a schedule costs real money, because every check is a live query. That is why free offers fall into three buckets:
- One-shot checkers. Type your brand, get a snapshot. No history, often no custom prompts.
- Free trials. Full features for 7 to 14 days, sometimes with a card, sometimes without.
- Tiny free tiers. A few prompts, rarely daily, rarely across many engines.
A QuickSEO review that scraped six tools' live pricing pages in June 2026 reached the same verdict: there is no perfect free tracker. I agree, and the rest of this guide is about getting the most out of what exists.
Why a single free check can mislead you
ChatGPT is non-deterministic. Ask the same question twice and you can get different brands in a different order. One free snapshot that says "you are mentioned" or "you are invisible" tells you very little.
Two data points from Promptwatch Data help explain why the pool is so noisy:
- In Promptwatch's average sources per response report, ChatGPT cites about 5 sources per web-search answer, while Google AI Overviews and Perplexity cite about 10. With so few citation slots, small shifts change your results a lot.
- In Promptwatch's ChatGPT query fanouts data, average fanouts per response fell from 2.15 in early December 2025 to about 1.84 by early March 2026, and query length dropped from roughly 117 characters to the high 80s. ChatGPT's behaviour shifts, so a tracker that only ran once last month is stale.
The practical rule: judge any free tool by whether it can repeat the same prompts over time. If it cannot, it is a snapshot tool, and you should treat it that way.
Free ChatGPT rank trackers compared
Prices and trial terms below come from the sources I could check (QuickSEO, Searchable, and vendor pages as of mid to late 2026). They change often. Confirm on each vendor's site before you commit.
| Tool | What you get free | Card needed | Paid entry point | Best for |
|---|---|---|---|---|
| HubSpot AEO Grader | One-time scored report (ChatGPT, Perplexity, Gemini) | No, but full report is email-gated | $50/mo for ongoing monitoring | A first baseline |
| Semrush AI Visibility Checker | Free one-off check | No | Toolkit from $99/mo | Existing Semrush users |
| Profound | Free one-off AEO report | No | Demo-led pricing | Enterprise curiosity |
| Otterly.AI | 14-day trial | No | Lite $29/mo, 15 prompts | Cheap trend tracking |
| Morningscore | 14-day trial, limited usage | No | From $49/mo | Beginners, small teams |
| ProRankTracker | 7-day trial, 100 terms | No | About $0.20 per prompt per month | Budget volume |
| Searchable | 14-day trial on Pro and Scale | Yes | About $1.25 per prompt per model per month | Fan-out visibility |
| Peec AI | Free trial | Check vendor | From $95/mo, 50 prompts, 3 models | Marketing teams |
| Writesonic | 7-day trial | No | From $79/mo annual, ChatGPT only | Existing Writesonic users |
| AI Rank Lab | 100 free credits on signup | No | Credit-based | One audit plus one prompt run |
A note on sourcing: I did not verify Otterly, Peec, Writesonic, or HubSpot pricing on their own sites. Those figures come from QuickSEO's June 2026 scrape.
One-shot free checkers
These are the right first step. They cost nothing, take a few minutes, and tell you whether you are in the conversation at all.
HubSpot AEO Grader
HubSpot's grader queries ChatGPT (GPT-5.4 mini at the time of QuickSEO's scrape), Perplexity, and Gemini, then scores you out of 100. The weighting is sentiment 40, presence quality 20, brand recognition 20, share of voice 10, and market competition 10. That is a sentiment-heavy score, which is worth knowing before you panic over a low number. You cannot define your own prompts, and it is one-time only.
Semrush and Profound free reports
Semrush has a free one-off AI Visibility Checker, but the full toolkit starts at $99/month with no standalone trial. Profound offers a free one-off AEO report, with paid plans handled through a demo. Both are fine for a snapshot. Neither gives you trend data without paying.
Profound
Promptwatch free AI visibility report
Promptwatch also has a no-login scan. Promptwatch's free AI visibility report checks how ChatGPT, Gemini, and Perplexity talk about your brand, gives a visibility score, and runs a crawler access check so you know what to fix. That crawler check matters more than people expect. Plenty of sites block GPTBot or other AI crawlers without knowing it, and no amount of tracking fixes that.
AI Rank Lab
AI Rank Lab has no free plan, but signup gives 100 free credits with no card. That is enough for roughly one site audit and one brand visibility prompt run across ChatGPT and several other engines. Its own article claims accuracy figures for competing tools, and since it ranks itself first, I would not lean on those numbers.
Free trials that give you real trend data
If you want to see movement over time, a trial beats a checker. The best ones need no credit card.
Otterly.AI
A 14-day trial with no card, covering ChatGPT, Google AI Overviews, Perplexity, and Copilot. The Lite plan is $29/month for 15 prompts. It is the cheapest sensible step up from a free check, and QuickSEO notes it was named a Gartner Cool Vendor in AI in Marketing in 2025.
Otterly.AI
Morningscore
Morningscore gives a 14-day trial with limited usage and no card. The interface is gamified, with XP-style progress and screenshots as brand mention proof. That sounds gimmicky, but for non-technical teams it keeps people looking at the data. Searchable's pricing comparison puts it at the expensive end per prompt ($6.90), so it is a friendly trial more than a bargain long-term.
ProRankTracker
Seven days, 100 terms, no card. At about $0.20 per prompt per month it is the cheapest per-prompt option in Searchable's comparison. The tradeoff: it does not show fan-out queries.
Searchable and Peec AI
Searchable offers 14-day trials of its Pro and Scale plans but asks for a card. It covers model-only answers, ChatGPT Search, ChatGPT Shopping, and fan-out queries. Peec AI has a free trial and paid plans from $95/month for 50 prompts across 3 models.
Pay as you go
AI Rank Checker charges about $0.13 per ChatGPT keyword check with no subscription. For a consultant doing one audit, that is effectively cheaper than any monthly plan.
Where free stops being enough
QuickSEO describes thresholds where free stops working, though the scraped copy cut off before listing them. Here are the ones I would use myself:
- You need history. The moment someone asks "are we up or down?", a one-shot checker cannot answer.
- You need your own prompts. Generic category prompts do not match how your buyers ask.
- You need more than one engine. ChatGPT and Google AI Overviews behave differently. In Promptwatch's social media citations data for Sep 28 to Oct 4, 2026, ChatGPT got 0.46% of its citations from social platforms while Google AI Overviews got 12.2%. Tracking one engine and assuming the rest match is a mistake.
- You need to know why. A mention count without citations or crawler data does not tell you what to change.
- You need to act. Dashboards report. They do not fix.
That last point is where tools split. Monitoring-only trackers stop at the score. Promptwatch goes further: it traces which of your pages get cited, shows IP-verified AI crawler logs so you can tell an access problem from a content problem, and uses a Content Agent and Action Board to write and prioritise fixes. It has no free plan, but it does have a 7-day free trial on monthly billing for Essential ($95/mo), Professional ($245/mo), and Business ($579/mo). Confirm current pricing at promptwatch.com/pricing.
How to run a useful free test in a week
You can learn a lot without paying if you are disciplined.
- Write 10 to 15 prompts your buyers would actually type. Mix category questions ("best X for Y"), comparisons, and branded queries.
- Run a free checker first to get a baseline score and spot obvious problems like blocked crawlers.
- Start one no-card trial (Otterly.AI or Morningscore are easy picks) and load the same prompts.
- Let it run for the full trial. Daily samples over 7 to 14 days beat any single check.
- Record four things: mention rate, position in the answer, which URLs get cited, and who shows up instead of you.
- Export before the trial ends. Some tools lock data when the trial expires.
Do not obsess over exact positions. Mention rate and citation share across many runs are the numbers worth trusting.
Which free option should you pick?
| Your situation | Start with | Then |
|---|---|---|
| Just curious if ChatGPT knows you exist | HubSpot AEO Grader or Promptwatch's free report | Decide if it is worth tracking |
| Small team, tiny budget | Otterly.AI trial | Lite at $29/mo |
| Non-technical, want friendly UI | Morningscore trial | Watch per-prompt cost |
| Lots of keywords, tight budget | ProRankTracker trial | Scale by prompt count |
| One-off client audit | AI Rank Checker pay-as-you-go | No subscription needed |
| Need to fix visibility, not just watch it | A trial of an end-to-end platform like Promptwatch | Content and crawler data |
| Existing SEO suite user | Semrush or SE Ranking AI add-ons | Check prompt limits |

Common mistakes with free trackers
- Treating a single check as a trend.
- Tracking only branded prompts. Everyone is visible for their own name.
- Ignoring crawler access. If GPTBot is blocked, your score will not move.
- Trusting vendor rankings. Leapd, KIME, Searchable, and AI Rank Lab each put themselves first in their own lists.
- Forgetting that trial prices and lengths change. Several sources I read disagreed with each other.
Final thoughts
Free gets you a snapshot or a short trial, not a monitoring programme. Use the checkers to find out whether you have a problem, use one or two no-card trials to see whether it moves, and only pay when you need history, multiple engines, or help fixing what you find.
