Free · private browser tool
Compare screenplay drafts — free script diff
Compare two screenplay drafts by scene, dialogue, character, exact text, and production impact. Load a rewrite example or paste Fountain and FDX privately in the browser.
Local screenplay comparison
What changed between these drafts?
Compare scenes, dialogue, cast footprint, word deltas, and production impact. The built-in rewrite example targets one concrete goal: Give Mara an active choice, make Jonah part of the mystery, and let the choice create the next complication. Both drafts stay in this browser.

Questions writers ask
Are either of my screenplay drafts uploaded?
No. Fountain and FDX parsing, scene matching, exact-text comparison, and memo generation run locally in your browser.
Can I compare Fountain with Final Draft FDX?
Yes. You can compare Fountain with Fountain, FDX with FDX, or one of each. Both formats normalize through Inkwell's production parsers before scene matching.
How does the tool know which scenes correspond?
It weighs scene numbers, headings, neighboring scenes, opening action, speaking characters, and relative position. Weak matches remain visibly marked for your confirmation instead of being forced.
Does the tool judge whether my revision improved the screenplay?
No. It reports observable facts such as a scene moving, dialogue-word changes, a new location, or a night exterior. It does not claim that pacing, character arcs, or note satisfaction improved.
What appears in the downloadable change memo?
The memo includes counts, scene headings, movement, word deltas, character additions, and production-impact inventory. It intentionally excludes action and dialogue body text.
Defined in the glossary
Revision colors
The industry color sequence (white, blue, pink, yellow, and onward) used to mark each revision pass on a locked shooting script so the set knows which pages are current.
Semantic changes
Differences between two versions shown at story structure level — this dialogue line rewritten, that scene moved — instead of a noisy character-by-character redline.
Page-one rewrite
A ground-up rewrite that rebuilds the script from a new structural plan while keeping what still serves the story — not a line edit.
