# GapCite > GapCite is a GEO/AEO AI-visibility tracking platform. It measures whether AI assistants (ChatGPT, Claude, Perplexity, Gemini, Grok, Mistral) surface a brand when answering real, unbranded, buying-intent questions, reporting a measured percentage, not an opaque score. ## What it does - Generates and validates buyer questions against real AI engines before trusting them as measurement (round-trip validation). A question that cannot reliably surface a known real brand is flagged, not silently scored as a confident zero. - Tracks competitors as real entities in the same queries used to measure the brand, rather than a separate assumed list. - Reports a visibility percentage with per-engine breakdowns and a plain-language Actions tab for what to fix next. ## Plans - Starter ($29/mo): 15 tracked prompts, 4 engines (ChatGPT, Claude, Perplexity, Gemini). - Growth ($69/mo): 50 tracked prompts, 7 engines (adds Grok, Mistral, DeepSeek). - Pro ($119/mo): 100 tracked prompts, 8 engines (adds Google's AI Overview). - Scale ($259/mo): the same 100 tracked prompts and 8 engines as Pro, per project, across 3 tracked projects/brands. ## Pages - [Homepage](https://gapcite.com/): product overview and signup. - [Pricing](https://gapcite.com/pricing): plans and a competitor pricing comparison. - [FAQ](https://gapcite.com/faq): measurement methodology, engine coverage, and plan details. - [Free scanner](https://gapcite.com/aivisibility/): a free single-page AI visibility scan, no signup or credit card, testing Perplexity and Gemini. - [Contact](https://gapcite.com/contact)
