Bring your chat history with you
Switching to Krater doesn’t mean starting over. Import your conversations from ChatGPT, Claude, or Gemini and they land in your sidebar — titles, full message history, images, and original timestamps included.
The import runs entirely on Krater’s servers, so you can close the tab and come back later. Re-uploading the same export is safe: already-imported chats are skipped, and interrupted imports resume where they stopped.
How to import
- Export your data from the provider (instructions below).
- In Krater, open Settings (profile menu, or
Cmd+,/Ctrl+,) and go to the Data & Privacy tab. - Under Import conversations, pick your provider — ChatGPT, Claude, or Gemini.
- Drop the export file onto the drop zone, or click Choose file.
- Watch the live progress bar. When it finishes, your chats appear in the sidebar.
Step 1 — get your export
| Provider | Where to export | File you get |
|---|---|---|
| ChatGPT | ChatGPT → Settings → Data controls → Export data | .zip sent by email |
| Claude | Claude → Settings → Privacy → Export data | .zip from Anthropic’s email link |
| Gemini | takeout.google.com → deselect all → My Activity → Gemini Apps → set format to JSON | .zip (or MyActivity.json / MyActivity.html alone) |
Exports are generated by the provider, not instantly — ChatGPT and Claude email you a download link, Takeout can take minutes to hours for large accounts. You don’t need to unzip anything; upload the archive as-is.
Step 2 — upload
The file uploads straight from your browser to private Krater storage — it never passes through a third party. Accepted files:
- ChatGPT:
.zip - Claude:
.zip - Gemini:
.zip,.json, or.html
Maximum export size: 2 GB.
Step 3 — let it run
Progress shows live (Importing X of Y conversations…). You can safely close Settings, refresh the page, or sign out and back in — Krater reconnects to the running job automatically. A background watchdog resumes any import that stalls, so large exports keep moving even if a worker restarts.
What gets imported
| Item | Imported? |
|---|---|
| Conversation titles | Yes — original titles preserved |
| Message history (your messages + AI replies) | Yes — full text, in order |
| Images in chats (uploads, DALL·E generations, Claude file images) | Yes — restored into your chats |
| Original timestamps | Yes — chats sort into your history by their real dates |
| Source label | Yes — each chat is tagged with the provider it came from |
| Non-image file attachments | No — file contents other than images don’t transfer |
| Provider-side memory, custom instructions, GPTs/Gems/Projects | No — these are platform features, not part of your chats |
Imported conversations are read like normal Krater chats. You can search them, organize them into Projects, share them, or keep chatting in them — replies continue on Krater’s 500+ AI models.
Re-imports, retries, and canceling
- Re-upload the same export any time. Each conversation is deduplicated by its source ID, so chats already imported are skipped — you’ll see them counted under “Skipped (already imported)” in the summary.
- A stopped import resumes. If a job was interrupted mid-conversation, the next run repairs the partial chat instead of duplicating it.
- Cancel any running import from the progress card — already-imported chats stay.
- Retry a failed, canceled, or stalled import with one click. It continues from where it stopped, not from zero.
- One import runs at a time per account.
If something fails
The summary at the end shows exactly what happened: imported, skipped, failed, and images restored counts. A whole-job failure tells you why:
| Message | Meaning |
|---|---|
| “The export could not be read correctly” | The file parsed but hit a format error — retry once, then re-download the export |
| “The export did not contain a supported conversation format” | Wrong file — check you picked the right provider and the right export type |
| “The import stopped responding” / “took too long” | Transient worker issue — click Retry; it resumes where it left off |
| “Some messages could not be saved” | A few conversations failed individually — the rest imported fine |
A single corrupt conversation never sinks the job — it’s counted as failed and the import moves on.
Privacy
- Your export file goes to a private storage bucket only you can access, and it’s deleted automatically when the import completes.
- Imported chats are exactly as private as chats you create in Krater — visible only to you, covered by the same data controls under Settings → Data & Privacy.
