Feature request: Highlight text and revisit saved highlights

ChatGPT Feature requests

I’d love to select and highlight text in ChatGPT conversations, with the option to attach a short personal note.

A “Highlights” view could bring together saved passages from an individual chat or across a Project, with links back to the original messages.

This would be especially useful for studying, interview preparation, research, or ongoing work—letting users revisit the points they’ve marked as important without scrolling through entire conversations.

I’d love to build on this idea with a lightweight, user-controlled annotation system for ChatGPT answers.

When I select a passage, I could highlight it in a color or assign one or more categories, then attach a personal note or question. A searchable Highlights view could collect saved passages across chats, while each Project would have its own view. Selecting a highlight should take me back to the exact passage in its original conversation, with the surrounding context.

Two actions would make this especially useful:

  • Start a new chat from a highlight, carrying over the selected passage and relevant context from its original conversation.
  • Combine highlights from different conversations and ask ChatGPT to compare or synthesize them—for example, to find themes, connections, or open questions.

The user should be able to choose which passages and context are carried into a new chat or synthesis. That would make saved highlights a personal, navigable knowledge base while keeping each passage connected to its source.

Thanks for considering this. It would be especially helpful for research, learning, and long-running projects.
