# Unvibe

> Unvibe checks how well ChatGPT, Claude, Perplexity and AI agents can understand and use your app, then gives you each fix ready to paste into your coding agent. Made for apps built with AI coding tools like Claude Code, Codex, Cursor, Lovable, Bolt, Replit, v0 and Windsurf.

A checkup reads a live website the way AI crawlers do (raw HTML, robots.txt and sitemap, no JavaScript), visits it as GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot and Googlebot to catch CDN or firewall blocks, and asks an AI what the app is. It scores 17 checks in three areas (Understood by AI, Readable by crawlers, Usable by agents) and turns every gap into a ranked fix with an instruction for your coding agent. After you deploy, Unvibe checks again and shows what improved.

Once AI can read the site, Unvibe tracks whether AI recommends it: AI mentions asks AI your buyer questions and records your position and who is named instead, weekly AI rank tracking repeats this every week, and the AI visibility score combines recommendations, position, fact accuracy and visitors from AI into one number. Also: fact check, a page audit, competitor benchmarks and head-to-head comparisons, buyer question research with search demand, answer pages written by AI, AI traffic tracking (visitors from ChatGPT, Perplexity and Claude), and an assistant that answers questions about your report.

Coding agents connect through Unvibe's MCP server at https://unvibe.app/api/mcp (sign in with your Unvibe account over OAuth) to read the report, fetch fixes, mark them done and re-run checkups.
