Notebook for ChatGPT — Highlight, Notes & PDF Export

About

Your ChatGPT history is where good ideas go to be forgotten.

You finish a long, useful conversation—full of explanations, code, references, and small breakthroughs. Two weeks later, you can't remember which chat had the answer you needed.

**Notebook for ChatGPT** fixes that. It treats every conversation like a document worth keeping.

What you can do:
  • Highlight passages: select any sentence in any reply and tap a color (yellow, orange, pink, blue). Highlights stick to the message even if you reload, switch chats, and come back days later.
  • Add notes: Your own annotations attached to highlighted text. Useful for capturing why an answer mattered, or what to do next. 
  • Ask follow-ups on a specific passage: Select something unclear, type a quick clarifying question, and the prompt gets composed for you with the quoted excerpt and your question.
  • Clean exports: Save your entire conversation to a beautifully themed PDF or plain Markdown. Your highlights and notes are included automatically, making it easy to turn chats into organized documentation.
  • Save and reuse prompts — type # in the composer to insert any of your saved prompts. Build your own library, stop retyping "Rewrite this in plain English…" for the hundredth time.
  • Tag and bookmark: Organize chats by topic (research/work/project X), bookmark important messages, and find them again instantly from the side panel.
  • Edit AI responses: Trim long-winded explanations, remove irrelevant tangents, or redact sensitive info before you export. Keep only the signal, lose the noise.
  • Backup and restore — export everything you've saved as a single JSON file, import it back after a reinstall or on a new machine.
  • Side panel — every highlight and note from every conversation, searchable, in one place.

Built for:
  • Researchers and analysts who run long fact-finding sessions
  • Students extracting study notes from explanations
  • Writers and consultants archiving briefing chats
  • Engineers turning debugging conversations into docs
  • Anyone who treats ChatGPT as a thinking partner, not a disposable search box

Your privacy:
Highlights, notes, prompts, tags, and bookmarks live in your browser. They never leave your machine.
