# AI-Visibility Tools With a Real, Ongoing Free Tier

A "free tier" checkbox on a comparison page can mean four different things: a self-hosted tool you run forever on your own API key, a standing hosted plan with real (if capped) capacity, a single one-time check with no account required, or a trial clock that starts the moment you sign up and eventually runs out. These 16 tools clear the higher bar: an ongoing free option, usable indefinitely, with no card and no expiry. Six put no vendor-imposed ceiling on use at all because the cost sits with your own API key; the other ten host the free plan themselves and cap it, but never take it away. Open any entry for its exact limits. Engine coverage, prompt caps, workspace and seat counts vary by an order of magnitude between the most generous plan here and the smallest, and two tools that both say "free tier" on their homepage can mean very different things once you read the fine print.

| Name | What it is | Why it's here | Pricing | API |
| --- | --- | --- | --- | --- |
| [geoSurge](https://citedindex.com/geosurge.md) | Tracks how ChatGPT, Claude and Gemini describe your brand, free on your own AI subscriptions. | Unlimited tracked prompts across ChatGPT, Claude and Gemini on its free "Free (BYOK)" plan, plus a full REST API, CSV/JSON export and MCP access; you pay only your own OpenAI/Anthropic/Google API usage. The most generous unlimited-use free plan in the index; only logit-level probability analysis and real-time crawler classification sit behind a paid Enterprise tier. | — | Yes |
| [auto-geo](https://citedindex.com/auto-geo.md) | Open-source CLI that audits, generates and rewrites pages for AI-search citation, then measures engine citations. | MIT-licensed and free forever with no hosted plan at all: a command-line tool that audits, generates, fixes and measures citation-readiness against five engines via your own API key. No dashboard, and it does not monitor Google AI Overviews. | — | Yes |
| [Archytas AISpy](https://citedindex.com/archytas-aispy.md) | Free desktop AI visibility tracker that runs locally on your own LLM API keys. | A free Windows/macOS desktop download, bring-your-own OpenAI/Anthropic/Google/Perplexity API keys, with no seat or prompt limit. | — | Yes |
| [Canonry](https://citedindex.com/canonry.md) | AI search visibility tracking plus AEO delivery, as an open-source platform, agency products and managed service. | Its self-hosted tier ships the full CLI, dashboard and API on local SQLite with your own model API key, under an FSL-1.1-ALv2 license that converts to Apache 2.0 two years after each release. | — | Yes |
| [AI Visibility Audit](https://citedindex.com/syntropic-ai-visibility-audit.md) | Self-hosted open-source audit of how ChatGPT, Gemini and Google AI answer buyer questions about your store. | A self-hosted Docker Compose stack under AGPL-3.0, using your own Gemini/Exa/DataForSEO keys, with a built-in sample dataset so you can explore before adding a key at all. | — | Yes |
| [GEORankHub](https://citedindex.com/georank.md) | Free GEO workbench: page diagnostics, JSON-LD and llms.txt generators, keyword expansion and 30/60/90-day plans. | Apache-2.0 licensed and self-hosted via Docker Compose, plus a separate hosted "GEORankHub" demo with company-directory and generator tools free to browse. Sign-up for the deeper diagnostic tools requires a Chinese mobile number. | — | Yes |
| [AthenaHQ](https://citedindex.com/athenahq.md) | AEO/GEO platform tracking brand visibility across 11 AI models, with content and technical actions. | A standing "Essential" plan with $25 of free credit (~300 credits) across five engines (ChatGPT, Perplexity, AI Overviews, Gemini and Claude), with no time limit stated. | — | Yes |
| [CiteLens](https://citedindex.com/citelens.md) | Tracks brand mentions and domain citations inside ChatGPT, Perplexity and Claude answers. | A genuine $0 "Free" plan: 10 tracked prompts, 3 AI engines, 100 engine calls/month, 1 workspace and 2 seats, though no API access at this tier. | — | Yes |
| [RankLens](https://citedindex.com/ranklens.md) | AI brand visibility tracker measuring how LLMs mention and rank a brand, with a Visibility Index. | A standing Free plan with standard-sampling entity probes and one free API key, plus a "PRO (Beta)" tier that is also free for the duration of its beta. Read that second one as temporary, not a permanent price point. | — | Yes |
| [Promptwatch](https://citedindex.com/promptwatch.md) | AI search visibility tracking with crawler logs and content agents that publish to your CMS. | An "Explore" plan at $0/month, described on its own pricing page as free forever, though the exact tracked-prompt and website caps are not published. Confirm the real ceiling before relying on it. | — | Yes |
| [Ubersuggest](https://citedindex.com/ubersuggest.md) | Neil Patel's SEO suite with an AI Search Visibility report that tracks brand mentions in AI answers. | A free $0 plan, but built around Ubersuggest's classic SEO toolset; the AI-search-visibility feature specifically is marketed on the free plan without a documented prompt allocation, and the paid Personal tier ($29/mo) is the first to state an AI-visibility number (10 prompts/project). | — | No |
| [Amplitude AI Visibility](https://citedindex.com/amplitude-ai-visibility.md) | AI search visibility, sentiment and competitor tracking built into the Amplitude analytics platform. | A $0 "Free" plan with 500 active AI Visibility prompts and 2M analytics events a month, no credit card, though AI Visibility carries no separate price at all, so the real ceiling is Amplitude's own analytics free tier rather than a GEO-specific allowance. | — | Yes |
| [SEORCE](https://citedindex.com/seorce.md) | AI answer-engine visibility tracking, rank tracking, content generation and one-click technical fixes in one platform. | A $0 "Free" plan, forever, no time limit stated: 1 website, 10 prompts/month, 20 keywords, 500 pages crawled/month, 50 AutoFix repairs and Google Search Console connected. | — | Yes |
| [AI Sightline](https://citedindex.com/ai-sightline.md) | AI visibility monitoring and AI traffic analytics across six answer engines, with ranked fix recommendations. | A genuine $0 "Free" plan, forever, no card required: 2 platforms (ChatGPT, Google AI Overviews), 3 prompts scanned every 7 days, and 100 API calls/month. Unusually, API access ships even at $0, where most rivals in this index gate it behind a paid plan entirely. | — | Yes |
| [EdenRank](https://citedindex.com/edenrank.md) | AI citation monitoring with an approval-first execution and verification loop across eight answer engines. | A genuine $0 "Free" plan, forever, no card required: 1 workspace, 5 active prompts, and 3 engines (Google AI Overviews, Google AI Mode, Microsoft Copilot; notably not ChatGPT or Perplexity). Unlike AI Sightline, there is no API at this tier; the read-only API is gated all the way to the $299/mo Concierge plan. | — | Yes |
| [CheckThat.ai](https://citedindex.com/checkthat-ai.md) | AI visibility index and brand tracker for B2B software, built by the AEO agency GrowthX. | A genuine $0 free workspace, forever, no card required: 50 custom prompts tracked daily across ChatGPT, Claude, Perplexity and Google AI Mode, plus 100,000+ pre-built industry prompts and browsing access to the full open benchmark index. | — | Yes |

## How this list is built

A tool earns a place here only if its own CitedIndex listing documents an ongoing free option usable indefinitely without a credit card: either a self-hosted or bring-your-own-key tier with no vendor-imposed usage ceiling, or a standing $0 hosted plan with a published (or vendor-stated "forever") cap. Excluded: a one-time check or a periodic audit (once every 90 days, for example), and a time-limited trial with no ongoing free plan beneath it. Both are covered separately in [What 'Free' Actually Means Across 70 AI-Visibility Tools](/blog/free-tier-vs-free-trial-ai-visibility-tools-2026/), the data report this list is drawn from. Every fact below is transcribed from that report's own sourced, vendor-page-verified figures, current as of the report's 2026-08-11 update. Re-verified against the live 92-listing corpus on 2026-08-18: membership unchanged at 16; checked and excluded GetCito (a genuinely self-hosted, BYOK Self-Host tier, but capped to a single domain on a weekly refresh, which is a vendor-imposed ceiling this page's bar excludes) and reconfirmed LLMrefs, Local Dominator AI Tracker, Rankshift and ZipTie remain time-boxed trials with no standing free tier beneath them. Pricing changes; re-verify against the vendor's live pricing page before relying on any single figure for a purchase decision, and see each tool's own listing for its full pricing table and sources.
