How to mark key decisions in a ChatGPT planning thread
Updated May 27, 2026
Quick answer
Planning threads in ChatGPT accumulate decisions, options, and rationale in a single stream with no structure to separate what was decided from what was considered. Going back to verify a decision means reading the whole thread or keeping a parallel decision log in another doc that quickly falls behind. GPT Master notes let you mark the specific exchange where a decision was made, attach a note to that passage, and return to it directly. The highlighted text stays visible in the conversation so the decision point stands out the next time you open the thread.
A planning conversation in ChatGPT can run long before settling on a direction. The decision itself might be buried in the middle of the thread, surrounded by the alternatives that were ruled out. Annotating the decision in place means future sessions start from a clear reference point rather than a re-read.
- 1
Locate the message where the decision was made
Find the reply or exchange in the planning thread that records the decision, the point where direction was set, an option was chosen, or a constraint was accepted. This is the passage to annotate.

Select the decision text and attach a note
Drag to select the key sentence or phrase in the message. Write a note with the decision summary, the date, and any relevant owner or follow-up. Save it. GPT Master highlights that passage and stores the note against it.

Jump to the decision point on future visits
Reopen the planning thread and the highlighted passage is visible in the conversation. Click the note in the Notes tab to jump directly to it. The annotation is an index of the decisions made.

Frequently asked questions
- Can I annotate multiple decisions in the same planning thread?
- Yes. Each decision gets its own note, anchored to its own passage. All of them appear in the Notes tab for the conversation, making the thread readable as a record of decisions.
- What if the decision spans multiple messages?
- Annotate the message that contains the clearest statement of the decision. For a decision that built across several exchanges, a conversation-level note summarizing the outcome is a good complement to passage-level annotations.
- Are annotated decisions visible to other people?
- No. Notes are stored locally in the extension on your machine. If you share the ChatGPT conversation link with someone, they see the thread without the annotations.
- Do planning thread notes work inside ChatGPT Projects?
- Yes. GPT Master notes work in standard chats, Projects, and Custom GPTs on chatgpt.com.
