I do a lot of long research sessions in ChatGPT, sometimes 40–60+ messages deep. The problem was always retrieval: useful answers and code snippets got buried, and finding them meant endlessly scrolling back through everything.
So I built a simple highlight system into my Chrome extension.
How it works:
You select any text and press Ctrl+Shift+H. It gets highlighted, saved, and stays there even after refreshes or restarts. There’s also a small navigation bar at the bottom with Previous / Next and a counter, so you can jump between highlights instantly.
Why this is better than just copying things:
Highlights stay in context, so you can still see the surrounding conversation instead of losing where it came from. You can keep working without breaking your flow to copy things out. Then at the end, you can just review everything you marked.
Where I actually use it:
- Marking action items during planning conversations
- Flagging useful code snippets while debugging without losing the thread
- Highlighting the best outputs during brainstorming so I end up with a clear shortlist
It’s free and works on ChatGPT, Claude, and Grok:
