Scrubble in action





Who it's for
Built for anyone who needs AI to understand exactly which part of an image they mean.
Precise AI image-editing instructions
Mark the exact part of an image to change, replace or remove, and attach a note, so ChatGPT, Claude, Gemini or Grok knows which area you mean. Scrubble does not edit or generate images; your AI assistant does.
Screenshot feedback for AI app-building
Point Lovable, Claude or ChatGPT to the exact button, spacing issue or broken layout on a screenshot, with a numbered note for each fix.
Design and mockup reviews
Annotate mockups, wireframes and UI designs so each piece of feedback stays attached to the element it refers to.
Numbered notes: A1, A2, A3
Each mark gets its own numbered instruction, so multi-part requests stay clear and organised in the AI composer.

Scrubble is growing
Scrubble currently works with ChatGPT, Claude, Google Gemini, Grok.com, Perplexity and Lovable, plus Grok inside X in its expanded/full-page experience only. Supported interfaces and features vary by platform.
In Development — Scrubble MCP Integration
We're building an MCP integration so AI tools can open the same Scrubble annotation surface and receive the marked image with structured instructions. An early prototype is being tested. It is not part of the Chrome extension and is not publicly available yet.
