# Tweak > Structured feedback for live websites. Chrome extension, on-site embed, and web review surface. Tweak is a Chrome extension that lets you draw, comment, and mark up any live website, then share a single link so anyone can see your annotations instantly. There is no account, no email, no sign-up, no payment, and no trial period. ## Pricing Free. There is no paid plan. There is no trial. There is no per-seat pricing. Everything is included. See https://tweak.page/pricing or https://tweak.page/pricing.md for the machine-readable version. ## Anonymous by design - No sign-up, no email verification, no login - No personal data collected - Random local display name and color generated in your browser - Annotations stay on your device until you choose to share ## Features - Drawing tools: Freehand drawing, shapes, arrows, and lines on any webpage - Threaded comments: Pin comments to any spot on the page - Inspector: Point at any element to capture its CSS selector and an AI-ready prompt for handoff to coding agents - Multi-inspect: Select multiple elements in one pass for bulk handoff - Measure: Pixel-precise distance and dimension measurement on any page - Area: Capture a rectangular region with a note attached - Quick grab: Hold Alt to arm element capture without switching tools - **Autosave:** Shared reviews persist to the server over HTTPS; open the same link again to pick up the latest snapshot - Shareable links: Recipients don't need the extension or an account to view - Works on any website: Production, staging, internal tools, third-party sites - Open source and self-hostable ## For AI coding agents (MCP) Tweak ships an MCP (Model Context Protocol) server, tweak-mcp, that turns annotations into a structured work queue for AI coding agents like Claude Code. Connect an agent to a share link and it can acknowledge, resolve, dismiss, or reply to each comment; updates persist via the same HTTPS API the web app uses.

Install the Tweak Chrome extension (free, no account) 2. Navigate to any webpage and click the Tweak icon 3. Draw, comment, or highlight anything on the page 4. Click "Share" to get a link anyone can open. No extension needed on their end 5. Optional: open the same link while a call is happening — changes sync live for everyone on the page ## FAQ Q: Is Tweak really free? A: Yes. 100% free. No paid plan, no trial, no per-seat pricing, no usage cap. Q: Is Tweak anonymous? A: Yes. No sign-up, no email, no profile, no login. No personal data is collected. Q: Does the other person need the extension installed? A: No. Anyone can view annotations via the share link. No install required. Q: Does it work on any website? A: Yes, Tweak works on any webpage. Q: Can multiple people annotate at the same time? A: Reviews persist over HTTPS — reopen the share link or embed to load the latest snapshot. Most teams hand off feedback asynchronously via the link or MCP. Q: What is the inspector tool? A: Point at any element on a page and Tweak captures its CSS selector and a copy-ready prompt for AI coding agents. Paste it into Claude Code or another agent and it has enough context to make the edit. Q: Can I send annotations to an AI coding agent? A: Yes. Tweak ships an MCP server (tweak-mcp) that lets agents like Claude Code watch a share link and process comments as a work queue. ## Contact Email: rusinvadym@gmail.com ## Optional - [Full details](/llms-full.txt)
