Free GEO tools in 2026: what to use before you pay
A practical guide to free GEO tools for AI search audits, content scoring, crawler checks, llms.txt, visibility monitoring, and fix workflows.
By GEO Repair
People searching for free GEO tools usually need one of four things: a quick audit, a content score, a crawlability check, or proof that AI systems mention their brand. The tools below do different jobs, so the right choice depends on the question you are trying to answer.
This list is based on the free tool pages and comparison pages visible for AI search and GEO tool searches on June 5, 2026. Pricing and limits can change, so treat the details as a starting point and verify the tool page before you build a process around it.
Quick picks by use case
- Best free starting point for code-backed sites: GEO Repair, because the free scan can hand off into a pull request workflow when the issue is technical.
- Best free page score: Frase, because its GEO Score Checker grades a single page across citation and structure signals.
- Best free technical toolbox: Geordy, because it groups readiness, crawler simulation, schema validation, and llms.txt validation in one hub.
- Best large free directory: Geolify, because it has a broad catalog of browser-run GEO utilities.
- Best free resources hub: OtterlyAI, because it collects prompt research, content tools, and benchmarks for teams learning the space.
GEO Repair free AI search readiness checkup
GEO Repair is for teams that want to know whether their site is technically ready for AI search, then fix the blocker if the report points to code.
The free checkup scans a public URL and reviews the things AI crawlers can actually fetch:
- Server-rendered content in the raw HTML
- robots.txt, sitemap, and llms.txt coverage
- Titles, descriptions, canonicals, Open Graph, and Twitter metadata
- Structured data that matches the visible page
- Heading structure, internal links, and answer-first sections
- Citation quality and sourceable claims
The useful difference is the repair path. If the report finds a blocker in a Next.js, React, or custom-coded site, the paid workflow can open a reviewable pull request instead of leaving the audit as another backlog item.
Use GEO Repair when the question is: what is blocking this site, and can we ship the fix?
Frase free SEO and GEO tools
Frase has two relevant free tools: a GEO Score Checker for individual pages and an AI Visibility Checker for whether AI systems cite a domain. The page score is useful when you are rewriting or reviewing one important article, landing page, or comparison page.
Use Frase when the question is: how strong is this page for citation-style content?
Geordy AI visibility tools
Geordy publishes a compact hub of AI visibility tools, including a GEO readiness scanner, AI crawler simulator, schema validator, llms.txt validator, metadata previewer, and content structure converter.
That makes it useful for technical marketers who want several small checks without committing to a full platform.
Use Geordy when the question is: which technical signal should I validate next?
Siftly free AI search tools
Siftly's free tools include an AI crawler accessibility audit, an llms.txt generator, and an AI visibility checker. The crawler audit angle is useful because many AI search issues start before content quality matters. If the page is blocked, thin in raw HTML, or missing crawl files, AI systems have less to work with.
Use Siftly when the question is: can AI crawlers reach and understand this site at a basic level?
Geolify free GEO tools
Geolify has a large free tools directory that spans llms.txt generators, schema builders, citation analyzers, content optimizers, AI search monitoring, prompt research, and competitor research. It is broad, so it is better for exploration than for one focused workflow.
Use Geolify when the question is: what free utility exists for this narrow GEO task?
Geoptie free GEO tools
Geoptie appears often in free GEO tool searches and publishes a comparison article around audit tools, rank trackers, keyword finders, content checkers, cannibalization checkers, and backlink tools. Its own audit is positioned around citation readiness, content authority, technical optimization, structured data, content depth, and AI friendliness.
Use Geoptie when the question is: which free GEO audit or tracking tool should I try first?
OtterlyAI free GEO resources
OtterlyAI is more of a resources and workflow hub than a single scanner. It is useful when you are researching prompt sets, content checks, benchmarks, and how AI visibility monitoring works before you choose a paid platform.
Use OtterlyAI when the question is: what should we learn or benchmark before buying a GEO platform?
What most free GEO tools do not do
Most free tools stop at one of these outputs:
- A score
- A crawler or schema warning
- A visibility snapshot
- A content recommendation
- A generated file such as llms.txt
Those outputs can be helpful, but they do not change your site. If the issue is a client-rendered pricing page, broken canonical, stale sitemap, missing schema, or blocked crawler rule, someone still has to make the edit.
That is where an audit-to-fix workflow matters. Use free tools to find the problem. Use a repair workflow when the problem lives in code, routing, metadata, structured data, crawl files, or content structure.
A simple tool stack
For most teams, the practical stack is small:
- Run a free readiness scan on your homepage and highest-intent pages.
- Validate metadata, schema, robots.txt, sitemap, and llms.txt.
- Review one or two money pages with a page-level content scorer.
- Check whether AI systems mention your brand for obvious buyer prompts.
- Turn technical blockers into tickets or pull requests.
Do that before paying for a monitoring platform. Visibility tracking is useful, but it works better after the site is crawlable, structured, and answerable.
