Point at any element in your web app and write what should change. TweakThis keeps the note with the element’s selectors, a DOM excerpt and a screenshot. Claude Code or Codex fetches it over MCP, makes the change in your code, and hands it back for your review.

Resolution from Claude Code
Made button.pay-now full width below the sm breakpoint in components/Checkout.tsx and kept the fixed width on larger screens. Checked at 390 px.
Context used: note, selectors, outerHTML, screenshot.
AcceptedClaude Code or Codex fetches the item over MCP, claims it, changes your code and reports back. Read the agent’s summary and any commit or pull request it linked in your dashboard, then accept it or reopen it with a note.
Hover and click to pick an element, step to its parent or child, or draw a box around anything without a usable DOM node.
Page URL, viewport, selector candidates, a bounded DOM excerpt and key computed styles arrive with every note. Input values are never read.
Every item carries a page screenshot and an element crop. Point with an arrow and black out anything that should not leave your screen.
Record clicks and navigation across pages with checkpoint screenshots. Fields are named, never their values.
Your agent lists, claims and fetches items at /mcp, asks you when something is unclear, and links its commit or pull request.
Projects match your localhost, preview and production URLs. Every fix waits in your dashboard until you accept or reopen it.
Start free. Point at the first thing you want changed and let your agent take it from there.
