1. On Character.AI web, open Profile > Profile Settings > Account > Manage Account & Data > Export data. On mobile, open Profile > settings > Export my data.
2. Download the export when it arrives and check for both speakers. If its format is not accepted, copy visible messages from the conversation into a .txt file using the plain-text example below. Do not upload account-only data.
Prepare a file
user: ...
assistant: ...3. Open Upload to HeyAck, sign in if asked, and choose a .json, .txt or .csv export, a PNG or JPG screenshot, or a ZIP with files of the same kind. Name screenshots in a ZIP so they sort into chat order. Check the detected conversations and both speakers before continuing.
Gotcha: check that exported files contain both sides of the conversation before uploading.
Can I upload more than one file?
Upload one file at a time. Put several .json, .txt or .csv exports in a ZIP. Put screenshots in a separate ZIP and name them so they sort into chat order. Check the detected conversations in the upload review.
What if my export is short?
A short export may not contain enough usable messages for training. Read the upload review, add more real conversation history if available, or keep using the character without claiming a trained version.
Can I delete it later?
Open Me > Settings > Export or close account at /app/me/privacy/data to delete an uploaded chat or source file. Saved memories remain; review and remove them at /app/me/memory.
