Best Free LLM Rank Tracker Tools in 2026

TL;DR: the best free LLM rank tracker in 2026

The best free LLM rank tracker depends on what you need: Listable Labs and LLMrefs both let you start free without a card, HubSpot's AI Search Grader gives a free one-off brand score, and Profound, ZipTie and Rankscale offer 7-day trials. None gives unlimited free tracking, because every run of a prompt costs money. Use free tools to test, then pay for trends.

Here is the honest summary. A free LLM rank tracker is good for one question: do ChatGPT, Gemini and Perplexity mention my brand at all? It is not good for tracking change over time. Terms below were checked on vendor pages in October 2026.

Why free LLM tracking is limited

A free LLM rank tracker has to pay for every answer it collects. Each tracked prompt means a fresh query to ChatGPT, Gemini or Perplexity on every run, and a useful baseline needs the same prompt repeated across days because AI answers vary. That is why vendors cap free use by days, prompts or engines, and why the free options below fall into three types: free accounts, time-limited trials, and one-off graders.

How we judged "free"

This guide is for marketers, founders and SEOs who want to measure AI visibility before committing budget. We looked at five things:

• What is actually free: a permanent free account, a time-limited trial, or a one-off grader.
• Limits you hit first: prompts, days, engines and brands.
• Citation data: whether free usage shows the source URLs behind answers.
• Card required: whether you must enter payment details.
• Upgrade path: what the cheapest paid plan costs when the free period ends.

Listable Labs is our product and is listed first for that reason; where its free route is limited, we say so.

1. Listable Labs: best free start that leads to action

Verdict: the best choice if you expect to act on what you find, not just look.

Listable Labs is an AI search visibility and AEO platform built in Bengaluru. You can get started free with no credit card and see how your brand appears in AI answers before choosing a paid plan. Its Insights, Actions, Impact loop covers visibility, mentions, citations and share of voice, then the Prompt Explorer, a knowledge base and AI-optimised article generation with review steps, then Google Analytics, Search Console, Bing Webmaster Tools and Cloudflare integrations to tie it to traffic.

Listable Labs also offers free tools: the AI Crawlability Checker shows whether AI crawlers can read your site, and the LLMs.txt Generator builds the file for you.

Limitations: ChatGPT, Google Gemini and Google AI Mode are included, while Perplexity, Google AI Overviews and Microsoft Copilot are paid add-ons. Claude, Grok, Meta AI and DeepSeek are not tracked. The free start is for trying the platform; ongoing tracking runs on a paid plan.

Best for: teams that want a free start now and a workflow to improve results later.

Starting at: free to start; paid plans from $89/month (Growth: 50 prompts, 4,500 analysed answers).

2. LLMrefs: best free account for keyword-based tracking

Verdict: the most generous way to explore many engines at low cost.

LLMrefs offers a free account with no credit card and a 7-day trial. It tracks keywords and auto-generates the fan-out prompts, covering ChatGPT, ChatGPT Search, AI Overviews, AI Mode, Gemini, Perplexity, Claude, Grok, Copilot, Meta AI and DeepSeek. The paid plan is a single $79/month tier with 500 prompts, unlimited projects and team members, a CSV export and an API.

Results refresh weekly, not daily, so it is a trend tool rather than an alert tool.

Best for: SEOs who think in keywords and want broad engine coverage.

Starting at: free account, then $79/month.

3. HubSpot AI Search Grader: best free one-off check

Verdict: a fast, no-account snapshot of how AI models perceive your brand.

HubSpot's AI Search Grader gives a one-time brand perception score out of 100 across five dimensions, using ChatGPT, Perplexity and Gemini. It needs no account. The catch is method: it reflects how models perceive your brand from their training, not a live retrieval test across buyer prompts, so it will not tell you whether you win a specific "best X for Y" question.

HubSpot AEO, the paid follow-on, costs $50/month for continuous prompt tracking on a weekly basis, across the same three engines.

Best for: founders who want a five-minute reality check.

Starting at: free for the grader; $50/month for continuous monitoring.

4. Profound: best trial for testing an enterprise tool

Verdict: powerful, but the free trial is a demo, not a workflow.

Profound's free Trial plan runs 50 prompts a day for 7 days across ChatGPT, Gemini and Google AI Overviews, in one language and region. The prompts cannot be customised, so you cannot test your own buyer questions. Beyond the trial, pricing is custom enterprise.

Use it to see the interface and the style of reporting, not to judge your own visibility.

Best for: enterprise teams evaluating vendors.

Starting at: free 7-day trial, then custom pricing.

5. ZipTie: best trial with your own prompts and no card

Verdict: a useful 7-day test, then pay only for what you run.

ZipTie's trial gives 25 daily prompts on ChatGPT, Google AI Overviews and Copilot, with no card required. After that, pricing is usage-based at about $0.01 per prompt per engine per daily check, so 100 prompts tracked daily on one engine comes to roughly $30 a month. It also offers an API and MCP access.

The metered model is cheap for small tests but harder to budget for at scale.

Best for: teams that want to pay per check rather than per plan.

Starting at: free 7-day trial, then usage-based.

6. Cairrot: best free first report with an AI-readiness audit

Verdict: low-cost tracking with a free first report to try it.

Cairrot invites you to run your first AEO report for free. Paid plans start at $39/month for 15 prompts on 2 LLMs (ChatGPT and Perplexity), rising to Pro at $99/month for 40 prompts across 5 LLMs. It also scores your site's AI readiness and has a WordPress plugin. It does not list Google AI Overviews or AI Mode coverage, and the Enterprise tier is capped at 100 prompts.

The free allowance beyond the first report is not stated on the pricing page, so treat it as a taster.

Best for: small WordPress sites that want an audit and cheap tracking.

Starting at: free first report, then $39/month.

7. Knowatoa: best for small B2B teams on a weekly cadence

Verdict: a solid trial, but weekly refresh only.

Knowatoa offers a free trial; its site does not state the length. The $59/month Starter plan covers ChatGPT, AI Overviews and AI Mode, and the $199/month Growth plan extends to all 7 AI services, including Claude, Gemini, Meta AI and Perplexity. It refreshes weekly, which is fine for monthly reporting but slow for fast-moving categories.

Best for: small B2B SaaS teams.

Starting at: free trial, then $59/month.

8. Rankscale AI: best 7-day trial for credit-based tracking

Verdict: broad engine coverage, with usage set by credits.

Rankscale's Pro plan at $99/month includes a 7-day free trial and 1,200 credits, where roughly a quarter of a credit buys one AI-engine query. It covers 10 engines, including ChatGPT, Perplexity, Gemini, Claude, Copilot, Grok and DeepSeek. Credits make costs harder to predict once the trial ends.

Best for: analysts who want many terms and engines.

Starting at: 7-day trial, then $99/month.

9. SE Ranking: best 14-day trial inside an SEO suite

Verdict: the longest trial here, useful if you also need classic SEO.

SE Ranking's 14-day trial includes 20 AI prompts a day plus AI competitive research for up to 3 domains. Its Core plan is $129/month with 100 AI prompts a day across five engines (AI Overviews, AI Mode, ChatGPT, Perplexity and Gemini). Nightwatch also offers a 14-day trial with no card, and plans from EUR 79/month.

Best for: teams that also want rank tracking and site audits.

Starting at: 14-day trial, then $129/month.

What free LLM rank trackers cannot do

Free access hides four limits worth knowing before you rely on the numbers:

• Small prompt caps. Fewer than 15 prompts swings too much to guide decisions. A reliable baseline needs 40 to 50.
• Short windows. A 7-day trial cannot show a trend, only a snapshot.
• Few engines. Free tiers rarely include every engine your buyers use.
• Thin citation data. Knowing you were mentioned is less useful than knowing which pages the answer cited.

Ahrefs is a good example of the other side: it does not run free trials, and its Brand Radar tracking is paid.

How to get a useful baseline without paying

1. Write 40 to 50 prompts a buyer would type, covering category, comparison and use-case questions.
2. Load them into the trial of a tool that accepts custom prompts, such as ZipTie, LLMrefs or Rankscale.
3. Record mention rate, citation rate and the top competitors named.
4. Run the AI Crawlability Checker to rule out a technical block.
5. Decide on day 6 whether the data justifies a paid plan.

Final verdict

Free LLM rank tracking is a starting point, not a system. Start free with Listable Labs or LLMrefs, take the HubSpot grader for a quick snapshot, use a 7-day trial with your own prompts to confirm the data, and pay once you need trends. When you are ready, start free on Listable Labs with no credit card, or connect it to your AI tools through the Listable Labs MCP.
