Chat Export Cleanup Reference
Copied AI chats often contain repeated labels, divider lines, and UI text. Clean the scaffolding, not the conversation meaning.
Common cleanup targets
| Export pattern | Cleanup rule | Keep when |
|---|---|---|
| User:, Assistant:, System: | Remove repeated line-start speaker labels. | Role identity changes the meaning of the prompt. |
| ChatGPT said: | Remove as copied UI scaffolding. | You are documenting the exact export source. |
| --- or *** divider lines | Delete divider-only lines. | The divider marks meaningful sections you will reference. |
| 00:00 or [00:00:04] | Remove when pasted from a mixed chat/transcript source. | You need time-aligned notes. |
| Repeated blank lines | Collapse to one blank line between turns. | Poetry, code, or layout-sensitive text depends on spacing. |
Cleanup is not redactionRemoving labels and spacing does not remove secrets, names, account data, or private business context. Review sensitive content separately.

Questions
What should a chat export cleaner remove?
It should remove export scaffolding such as common line-start labels, divider lines, timestamps, and excess blank lines while preserving the actual conversation.
Should I remove system messages?
Remove system labels only when they are scaffolding. Keep system instructions when they explain why the conversation behaved a certain way.
