TweakThis vs Markup.io
Both tools let clients comment on a live website. Markup.io is a review tool for creative teams that also takes PDFs, images and video, priced by MarkUps a month with unlimited users; TweakThis is a browser extension that hands each note to Claude Code or Codex over MCP and brings the fix back to the client.
