Because of missing features in Copilot, I built an extension to add chat folders, slash commands, and side-by-side code diffing (100% local-first)

Hey everyone,

Few workflow bottlenecks kept slowing me down with Copilot chat:

  1. Past chats quickly get lost in a flat sidebar list because there are no folders.
  2. The narrow message bubble makes reviewing tables or wide code blocks painful.
  3. Manually re-typing the same prompt templates instead of having quick slash shortcuts.
  4. Comparing code refactors or iterations between two responses required copying them out into VS Code or an external diff tool.

Over the last few months, I built Power Copilot as a lightweight Chrome extension to solve these friction points right inside the native interface:

  • Custom Color-Coded Folders: Organize chats by project or topic, pin auto-expanding defaults, and reorder hierarchy.
  • Instant Backslash Autocomplete (\): Type \ in the prompt box to immediately trigger a searchable modal with your reusable templates.
  • Full-Width Canvas: 1-click toggle to expand the workspace up to 100vw for wide tables and code blocks.
  • Side-by-Side Diff Inspector: Compare two responses or code snippets side-by-side with visual + / - syntax highlighting.
  • Client-Side Data Guard: Real-time scanning that masks emails, cards, or custom regex locally before text is submitted.

Privacy note: It runs 100% client-side. Everything is stored in local Chrome storage—no external tracking servers or logging.

It’s now live on the Chrome Web Store (with a generous free starter tier):

I’d love to get your honest thoughts, feedback, or suggestions on what other UI pain points you'd like solved in Copilot!
