Chat History Import Triage

Turns an exported Claude/ChatGPT history into a privacy-reviewed, triaged list of what to ingest, archive, or delete.

UtilitiesIntermediate★ 288⑂ 50AI score 8/10Last updated: Sep 23, 2026

What it does

  • Converts a chat export into one Markdown file per conversation via scripts/chat_export_to_md.py, skipping very short exchanges.
  • Runs a privacy pass first: flags conversations touching health, money, other people's private info, or confidential work — you decide, the assistant deletes nothing on its own.
  • Triages the remainder into three piles (worth ingesting / archive in raw/ / delete suggested) and reports them before moving anything.
  • On approval, ingests only the first pile, building pages around your reasoning and conclusions rather than the assistant's explanations, with dates recorded on every page.

Who it's for

  • People moving years of AI chat history into a personal knowledge vault.
  • Anyone worried that a raw export contains sensitive material that shouldn't be synced or committed.
  • PKM users running a second-brain-os style workflow.

Examples

  1. "I unzipped my ChatGPT export — tell me what's worth keeping." → conversion counts, a privacy-review list, and an ingest shortlist.
  2. "Import my Claude history into the vault." → an aggressively filtered triage (roughly 9 in 10 chats are throwaway lookups) that only acts after you approve.
  3. "Just pull out last year's architecture debates." → dated notes centred on what you concluded and why.
