Best Free GEO Checkers and Audit Tools in 2026
The free GEO checkers, scanners, and audit tools worth running in 2026, ranked by what the free pass actually shows you.
The first question most teams ask about AI visibility is the cheapest one: where do we stand, for free, before we buy anything? The honest answer is that a free checker is a mirror, not a meter. It shows you a snapshot, sometimes a score, and almost never the trend, the crawl, or the conversion. The tools below are the free passes worth running in 2026, ranked by what the free tier actually shows you rather than what the marketing page promises.
The rule for this list: a tool only appears if its catalog entry states a real free offering, whether that is a free tier, a free scan, a free audit, or a free report. Free trials that take a card are not the same thing and are noted as trials, not free tiers. Everything here is sourced from each tool's published entry.
1. Promptwatch
Promptwatch opens this list because its free Explore tier is a real working tier, not a teaser. Explore is free, with 10 prompts, ChatGPT only, 1 project, and 1 seat. That is enough to run a small set of buyer prompts against ChatGPT on a daily cadence and see how the answers cite your brand, which is more than most free checkers let you do. The wider platform is what you move to when the free pass stops being enough: Essential at $95 a month with a 7-day trial covers 50 prompts and 6,000 responses across the full engine set, and the agency tiers start at Kick-off $199 a month with unlimited projects and prompts.
What makes the free tier worth ranking first is the stack behind it. Even on Explore you are looking at the same data model that, on paid plans, adds citation analytics down to the page and Reddit and YouTube level, Agent Analytics crawler logs with a crawl-to-citation path, visitor analytics that tie AI-referred traffic to conversions, and Content Agents that publish to Webflow or Framer. The free pass is a real entry point into a measurement platform, not a one-shot score. The limit is honest: ChatGPT only and 10 prompts means you outgrow it fast if you are serious.
2. HubSpot AI Search Grader
HubSpot AI Search Grader is the zero-cost starting point the category defaults to, and it earns the second slot for sheer accessibility. It is free, needs no account, and returns an instant score across ChatGPT, Perplexity, and Gemini with a brand sentiment snapshot and a share-of-voice estimate. If you need a conversation starter for a budget meeting, this is the tool to run before buying anything else.
The limitations are the ones its own entry is blunt about. It is a one-shot snapshot with no history, no trends, no alerts, and no custom prompts. It covers only three engines, with no Claude, Copilot, Grok, AI Overviews, or AI Mode. The scores are stochastic and vary between runs, and HubSpot's own disclaimer says results are not guaranteed. Mention counts appear derived from indexed content rather than real query volume, and the methodology is unpublished. Treat the number as a mirror, then move to a tracker if it surprises you.
3. VisiScan
VisiScan is the free pick for local service businesses. Its free scan costs nothing and asks 5 questions with 2 samples per engine across ChatGPT, Claude, Perplexity, and Gemini, up to 40 answers, one scan per URL. It scores visibility, whether you are named in the answer, and readiness, whether AI can find and cite you. For a plumber or a dentist who has never run a GEO check, that free pass is worth a minute.
The paid steps above it are a full report at $49 one-time, with 12 questions and up to 144 answers plus schema and llms.txt files to paste, and a Monitor plan at $29 a month for weekly re-scans and an AI-traffic beacon. The cons are honest about scope: four engines only, no Grok, Copilot, AI Overviews, or AI Mode, and the AI-traffic beacon counts AI-referred visits without the conversion attribution a full platform gives you. The free scan is the useful part. Do not confuse the $29 Monitor with a Promptwatch plan, because Promptwatch has no $29 SKU.
4. AthenaHQ
AthenaHQ makes the list because its free Essential tier is a real trial, roughly 300 credits, which its entry describes as working as a real trial rather than a teaser. That is enough to run the Action Center across nine engines on a small prompt set and see how visibility data becomes assignable optimization tasks like schema generation and content reformatting. For a team evaluating whether an action-queue workflow fits them, the free credits are a genuine test.
The catch is everything above free. Starter is $295 a month and single-country, and the features reviewers praise, the ACE Citation Engine, personas, and multi-region, sit in an Enterprise tier reported at roughly $2,000 a month and up. Credit-based usage is unpredictable, with reviewers reporting a month of credits burned in the first week. The free tier is the best part of the offer. The paid tiers are where the math gets hostile.
5. SEO MCP
SEO MCP is the free pick for teams who want their coding agent to do real SEO work without a subscription. Its free tier is $0, with 50 calls a month and 36 of the 39 tools, covering site auditing, Search Console, GA4, Google Indexing, IndexNow, Core Web Vitals, schema, and sitemaps. It works with Claude, Cursor, Windsurf, and any MCP-compatible client. For a developer running a quick audit and an indexing pass on a side project, the free tier is genuinely usable.
The limit is scope. SEO MCP is MCP for SEO, not MCP for AI visibility. Its cons note no published AI crawler log tracking, citation analytics, or visitor conversions, and no prompt tracking with volumes, difficulty, or fan-outs across AI engines. The free tier also omits 3 of the 39 tools and caps at 50 calls. Pro is $29 a month for 5,000 calls and all 39 tools. Use the free tier for technical SEO and indexing, then reach for an AI visibility platform when the question becomes why ChatGPT does or does not cite you.
6. Qwairy
Qwairy earns a row for its no-card free start: 120 credits with no card, plus a no-account audit across ChatGPT, Gemini, and Copilot. That is enough to spend an afternoon seeing how a credit-metered GEO suite feels across 10-plus engines on a paid plan. MCP is on all paid plans, and the REST API starts at Growth.
The free credits are also the warning. Its cons note that the module list is a Promptwatch-shaped checkbox pile, that 1,300 Starter credits vanish in days if you query many models daily, and that analyses pause when credits hit zero. The homepage and the pricing FAQ disagree on whether the trial is 120 or 100 credits. Spend the free credits once. Do not build a program on a meter that stops the product when it runs out.
7. Okara
Okara makes the list for its free AI CMO plan at $0, which covers analysis and strategy: a website analysis, a product info document, positioning, and a 30-day marketing strategy. For a founder who wants a structured read on their GEO and SEO posture without a card, the free plan is a real deliverable.
The Coding Agent, the part that ships JSON-LD schema, llms.txt, canonicals, and meta tags as GitHub pull requests, is gated behind AI CMO Lite at $129 a month and Pro at $249. The cons note no published AI crawler log tracking, citation analytics, or visitor conversions, and no CMS publishing to Webflow or Framer for GEO articles. The free plan is strategy. The execution loop is paid.
8. Seology
Seology is the free pick for technical SEO and GEO audits shipped as code. Its Starter plan is free, covering 1 site with weekly scans and 50 auto-fixes per month, with a SEO score dashboard and community support. The agent runs 200-plus checks across technical SEO, on-page, structured data, Core Web Vitals, indexation, and GEO visibility for ChatGPT, Perplexity, Claude, and Gemini, and classifies each issue as auto-fixable or flagged.
The free tier is real but bounded. Pro is $49 a month for 5 sites, daily scans, unlimited fixes, GEO optimization, and API access. The cons note no published AI crawler log tracking, citation analytics, or visitor conversions, and Autopilot mode opens PRs automatically, which needs a real review habit. For a single site that wants deterministic fixes shipped to a repo for free, Starter is a strong entry.
9. Atlas for AI
Atlas for AI earns a row for its free visibility report plus a free trial, with no card. The free report gives a daily scorecard across ChatGPT, Claude, Perplexity, Gemini, and Grok, with visibility, mention, citation, and recommendation rates, average list position, citation URL tracking, and competitor share of voice, plus a site health scanner for llms.txt, structured data, markdown, and crawlability.
The honest caveat is money. Its entry notes that public dollar amounts were not on the homepage when fetched, and the pricing URL timed out. Starter is one brand, 25 prompts, any three of five platforms, and Copilot is listed as soon rather than shipping. Do not budget it until the trial screen shows a number.
10. Gumshoe AI
Gumshoe AI rounds out the list with a free audit priced at roughly $0.10 to $0.20 per conversation on the paid side. The free audit is enough to see how the product frames AI visibility for a single brand before committing to a metered plan.
Its entry is thin on the free tier's exact scope, so treat it as a free look rather than a working tier. The broader platform's depth, crawler logs, visitor conversions, and CMS publishing, is not on the listing. Run the free audit, then decide.

Who should pick which
If you want a free tier that is a real entry into a measurement platform, Promptwatch Explore is the one to start with, because the same data model extends to citation analytics, crawler logs, and content publishing when you outgrow 10 ChatGPT prompts. If you need a no-signup score for a budget meeting, HubSpot AI Search Grader is the fastest. If you run a local service business, VisiScan's free scan is built for you. If you want to test an action-queue workflow, AthenaHQ's free credits are a real trial. If your free use is technical SEO through a coding agent, SEO MCP or Seology Starter ship fixes as code for nothing. If you just want a free look at a credit-metered suite, Qwairy or Okara give you that without a card.
The recommendation
A free checker answers where you stand today. It does not answer why, and it does not answer what to do next. That gap is the whole reason a platform exists. Promptwatch's Agent Analytics crawler logs show which AI bots hit your site and which crawls preceded a citation, and the Content Agents turn the resulting content gap into published pages you review before they go live.
