Save named versions of every scene. Compare any two side by side with word-level diff highlighting. Never wonder what you changed — or lose a draft you wish you had kept.

Try ProseEngine FreeEvery time you revise a scene, you lose the previous version. The paragraph you cut might have been better. The dialogue you rewrote might have had more energy in the original. The pacing you tightened might have lost something important. Without a way to compare, you are editing blind.
Version diff gives you named snapshots of any scene that you can compare at any time. Save a version before a major edit. Save another after beta feedback. Save one more after your final polish. Then compare any two — word by word — to see exactly what changed.
Additions appear in green. Deletions appear in red. You see every word that was added, removed, or moved. No guessing, no re-reading both versions and trying to spot differences. The diff does the work for you.
This is the same concept that software developers have relied on for decades — version control — adapted for fiction writers who need to track how their prose evolves across multiple revisions.
Save versions with meaningful names like "First Draft", "After Beta Feedback", or "Final Polish." Every snapshot is labelled and dated so you always know which revision you are looking at.
Not just line-by-line — word-by-word. See the exact words that were added, removed, or changed between any two versions. Green highlights for additions, red for deletions. Precision down to the single word.
Compare any two versions in a clean side-by-side layout. Pick the "before" and "after" from your saved versions. The differences are highlighted instantly so you can scan changes at a glance.
No version is ever deleted automatically. Your complete revision history is preserved for every scene. Go back to your very first draft at any time, even months later.
Watch your writing improve over time. See how each round of edits shaped the scene — from rough first draft to polished final version. Understand your own editing patterns and tendencies.
Save a version before running any AI improvement tool. Save another after. The diff shows you every change the AI made, so you decide what stays and what gets reverted. Full transparency, full control.
Three steps. No configuration. Save, compare, and see every change.
At any point while editing a scene, save a named snapshot. Give it a label that makes sense to you — "Before restructure", "Post-workshop feedback", "Submitted draft." The full scene text is preserved exactly as it was.
Open the version diff panel and select any two saved versions to compare. It does not matter how far apart they are — compare your first draft against your final polish, or two adjacent revisions.
Instantly see a word-level comparison. Additions are highlighted in green, deletions in red. Scan the entire scene to understand what changed, or focus on specific paragraphs. Every difference is visible at a glance.
Revision is where good writing becomes great writing. But revision without visibility is dangerous. You make changes, lose the original, and can never compare. You tighten a paragraph and lose the rhythm it had. You cut a line of dialogue and forget the subtext it carried. You accept an AI suggestion and cannot remember what your original said.
Version diff makes revision reversible. Every change is visible, every original is preserved, and every comparison is instant. You edit with confidence because you know you can always look back.
Writers who track their revisions also learn faster. When you can see how a scene evolved from first draft to final — every word that was cut, added, and rewritten — you start to understand your own editing instincts. You see which changes made the scene better and which ones were lateral moves. Over time, this builds a deep awareness of your craft that no writing course can teach.
AI writing tools can improve your prose — but only if you stay in control. The risk with any AI edit is that it changes something you did not intend. A character's voice shifts. A deliberate stylistic choice gets smoothed away. A nuance gets lost in the optimization.
Version diff solves this completely. Save a version before running any AI improvement. Save another after. Then compare them word by word. You see every single change the AI made — not a summary, not a vague description, but the actual words that were added, removed, and altered.
Keep what works. Revert what doesn't. This is how professional writers use AI: as a tool you oversee, not a black box you trust blindly.
See every word the AI touched. No hidden changes, no surprises. You approve or reject each modification with complete awareness of what was altered and why it matters.
Compare the AI version against your original. Keep the improvements that make the scene stronger. Revert the changes that lost your voice or intent. The diff makes selective editing effortless.
Version diff is a tool that lets you save named snapshots of any scene and compare any two versions side by side with word-level highlighting. Additions appear in green, deletions in red, so you can see exactly what changed between drafts without reading both versions line by line.
There is no limit to the number of versions you can save. Every snapshot is preserved permanently, so you can save as many named versions as you need — first draft, after beta feedback, post-edit, final, and anything in between.
Yes. Save a version before running any AI improvement, then save another version after. The diff view shows you every word the AI changed, so you stay in full control of what makes it into your final manuscript.
Version diff is available on all paid tiers — Writer, Author, and Studio. It is a core editing tool designed for any writer who wants to track their revision history and compare drafts with precision.
Every revision tracked. Every version preserved. Every change visible at a glance.
