How to annotate a ChatGPT conversation
Updated May 27, 2026
Quick answer
ChatGPT provides no annotation layer. The thread title is the only label you can add, and useful context disappears once you step away. Most people keep a separate notes doc open and copy-paste passages over, which breaks the link back to the source. GPT Master adds free-form notes to any ChatGPT conversation, with the option to anchor a note to a specific passage you select. The selected text is highlighted in the conversation on every reload. Notes live in the right-panel Notes tab, stored locally, and nothing about them is written back to ChatGPT.
Annotating a conversation means capturing what a specific exchange means for you, not just what it says. A useful reply in a planning thread might need a note about which decision it validated, or which person needs to see it. ChatGPT gives you no place to put that context. GPT Master adds a Notes layer so the annotation lives next to the source, not in a separate app.

Open the Notes tab in the GPT Master right panel
Click the GPT Master right panel icon while any ChatGPT conversation is open. Switch to the Notes tab. This is where annotations for the current conversation are stored and where new ones are created.

Select a passage and attach a note to it
Highlight any text in a ChatGPT reply. A popover appears with the option to attach a note. Type your annotation and save it. The selected passage is stored and will be highlighted in the conversation the next time you reload.

Return to the annotation later
Reopen the conversation and GPT Master finds the noted passage and highlights it in place. Click the note in the Notes tab to jump to the highlighted text. The annotation stays anchored to the passage you selected.

Frequently asked questions
- Can I annotate a conversation without selecting a specific passage?
- Yes. You can add a conversation-level note from the Notes tab without highlighting any text first. That note attaches to the conversation but does not anchor to a specific message or passage.
- Does annotating a conversation change what ChatGPT sees?
- No. Notes are stored inside the extension against the conversation id. ChatGPT never sees the annotation text, and it does not affect the model context or conversation history.
- What happens to the passage highlight if the conversation is long?
- GPT Master searches for the first occurrence of the noted text in the message you selected it from and re-highlights it on reload. The highlight works in long conversations the same way it does in short ones.
- Are notes free?
- Yes, with a cap on the number of notes you can keep on the free tier. GPT Master Pro removes the cap.
