All processing for core tools runs locally in your browser. Privacy policy

How to use

  1. Edit a prompt in the Editor (draft autosaves).
  2. Here, set a title and label (Draft / Slim / Release), then Save editor draft.
  3. Select two versions to see a line-level diff (+ / −).
  4. Open in Editor to restore a snapshot into the live draft.

FAQ

Are versions uploaded?

No. Snapshots stay in browser localStorage under this site’s storage prefix.

What do labels mean?

Draft = early, Slim = compressed/trimmed, Release = ready to ship. Custom is free-form tagging.

How is the token count computed?

At save time we count with the editor’s current target model (same stack as the Editor).
