# PinAppAI > The change-request layer for AI-built sites. Reviewers drop a pin on any element of a live site and say what should change in text or voice; the AI dev agent (Claude Code, Codex, Cursor, or a custom pipeline) receives a structured, locator-precise change request instead of a Slack screenshot. PinAppAI is MCP-first: an AI coding agent connects over the Model Context Protocol and drives the whole review loop: collect change requests into an Inbox, apply them one command at a time, and generate an AI-diff review page reviewers approve or reject item by item. Every surface shares the same #N change-request identity. There is nothing to install to try it: share a review link and reviewers annotate your live site through review.pinappai.com, or review it in their own logged-in tab with the reviewer Chrome extension. There are four ways to capture intent (free-form pins, element pins, screenshot-region pins, and text-selection pins), each with optional voice dictation. Free for solo builders (3 projects); paid tiers add unlimited projects, multi-seat roles, and enterprise controls. ## Documentation - [Getting started](https://pinappai.com/docs/getting-started/): Sign up, connect your AI agent over MCP, and let one workflow, setup-project, take you from zero to collecting structured feedback in about 5 minutes. - [The review link (no-install reviews)](https://pinappai.com/docs/review-link/): Share one URL and reviewers annotate your live site with zero setup. The review tools load automatically, no widget embed, no account gymnastics. - [The reviewer Chrome extension](https://pinappai.com/docs/extension/): Review the real site in your own tab: pages behind logins, in-app flows, and strict security policies included. Sign in once; no email codes on any page. - [Site-wide feedback widget](https://pinappai.com/docs/widget/): Embed a single script tag and reviewers can pin a comment, pick an element, or capture a region from any page of your site. - [The iteration loop](https://pinappai.com/docs/iteration-loop/): How PinAppAI organizes review rounds: an Inbox of change requests, one Apply command that hands them to your AI agent, and per-item reviewer verdicts. - [AI-diff review (the /changes/ workflow)](https://pinappai.com/docs/changes-review/): Generate a /changes/ page from your latest changes and let reviewers approve, reject, or rewrite each one, on the review page or the page where it lives. - [MCP server for AI agents](https://pinappai.com/docs/mcp/): Drive the PinAppAI iteration loop from Claude Code, Codex, Cursor, Continue, or any MCP agent: install, drain the Inbox with apply, and generate /changes/. - [Reviewer access & permissions](https://pinappai.com/docs/reviewers/): Who can leave feedback on your project: open access vs allowlist, inviting reviewers, removing them, and what 403 errors mean. ## Product - [Homepage](https://pinappai.com/): What PinAppAI is, the four ways to capture intent, and the review loop. - [Pricing](https://pinappai.com/pricing/): Free for solo (3 projects, 14-day pin history), Pro ($9/mo: unlimited projects, no branding), Team ($15/seat: roles + custom AI prompt). - [MCP server](https://pinappai.com/mcp/): Connect any MCP-aware AI agent and run the loop from your editor.
