A new draft.
A clear record.

Compare two screenplay drafts. Read exact line changes, review scene by scene, and keep your notes with the original files.

Actual Reviser iPad screen with scene sidebar and baseline and revised script columns

Changes you can hand to production.

Local Fountain and UTF-8 text comparison, insertion and deletion-aware source lines, added/removed/modified/moved scenes, review notes and a source order map.

Precise scope.

Scene identity uses normalized heading and occurrence. Repeated headings require manual checking. Renamed headings are added/removed. Classification is a limited Fountain heuristic; Reviser is not a screenplay editor or full Fountain renderer. PDF and FDX import are not supported.

Up to 1 MiB, 3,000 lines, 2,000 characters per line and 500 headings per draft; 40 saved comparisons, each with a 4 MB JSON backup limit including notes. Export JSON or ZIP for external backup. No cloud sync.
