Delete a source

Sources are easy to add and easy to delete. Deleting frees up storage quota and removes the source's PoKs from your library.

How

1. Open Sources → click the source
2. Top-right menu → Delete source
3. Confirm. The source is queued for deletion within a minute.

What gets deleted

• The uploaded file or transcript
• All embeddings (the source disappears from /search results)
• All Points of Knowledge auto-extracted from the source
• The source's processing history

What survives

• Your saved decks. Decks live independently from sources; deleting a source doesn't delete decks made from it. They show up in Saved decks with a small "(source removed)" tag.
• Your quiz history. Same logic. You can still see what scores you got, even if the underlying source is gone.
• Your /clear-ed chats. Already gone, not affected.

What you can't recover

Deletion is permanent. There's no soft-delete, no trash, no 30-day grace. If you need the source back, re-upload it (Ritsu will reprocess from scratch — no PoK matching against the old data because the old data is gone).

Free up storage faster

The Sources page footer shows your current storage usage and limit. To stay under the cap:

• Delete sources you've finished studying (their decks survive)
• Delete uploaded files where you only needed a single chapter
• On Pro, you have 50 GB — basically unlimited for normal use; on Free, 1 GB fills up at ~20 textbook PDFs

Tips

• Delete vs. archive. Ritsu doesn't have an archive concept yet. If you want to "set aside" a source without losing access, leave it. There's no benefit to deleting unless you're hitting storage limits.
• Bulk delete. Hold Shift on the Sources page to select multiple, then click Delete. Confirmation is per-source for safety.
• Source delete in the API. Coming when the API ships publicly. For now, only the UI deletes.

Trouble

• "Delete failed" — usually transient. Refresh and retry. If it persists, contact support@ritsu.ai with the source ID (visible in the source's URL).
