Import

HAEVN can import conversations from external sources — useful for seeding your archive with existing exports before you start using the sync extension, or for restoring from a backup.

Supported import formats

Source	Format	How to get it
ChatGPT	ZIP file	Settings → Data controls → Export data
HAEVN backup	ZIP or JSON	From a previous HAEVN export

How to import

Open the archive (click Archive in the HAEVN popup, or right-click the extension icon → Options).
Click the IMPORT button in the archive toolbar.
In the import dialog, click Choose file and select your ZIP or JSON export file.
Click Import. HAEVN processes the file and adds the conversations to your archive.
The search index rebuilds automatically once the import completes.

Importing from ChatGPT

ChatGPT’s native export format is a ZIP file containing your full conversation history. To export from ChatGPT:

Go to chatgpt.com and open Settings.
Navigate to Data controls → Export data.
Click Export and wait for the email with your download link (this can take several minutes to hours depending on your history size).
Download the ZIP file from the link in the email.
Import the ZIP file into HAEVN using the steps above.

What happens during import

Each conversation is added to your archive with its original timestamps and metadata
Attachments and images are extracted and stored in OPFS
Duplicate conversations (matching source ID) are skipped by default
The search index is rebuilt after all conversations are imported
