Compare text versions, cherry-pick the best parts, and compose a final draft in a row-aware Mac workspace with Source Shelf, save slots, and snapshots.
DiffDraft is a Mac-first workspace for comparing text versions and composing a final draft from the best parts.
It is for writers, editors, lawyers, developers, prompt designers, localization reviewers, documentation authors, and anyone who needs more than a normal two-pane diff view.
Instead of opening several text files side by side, keep multiple versions in a Source Shelf, focus on two sources at a time, and write the final draft in a pinned Compose Draft lane between them.
Compare, compose, and continue later:
• Add multiple plain-text sources to a Source Shelf
• Focus on two active source versions at once
• Keep the Compose Draft pinned in the center
• Cherry-pick from the left source, right source, or both
• Edit the draft directly with normal writing flow
• Switch active sources without clearing the draft
• Save work in resumable session slots
• Create manual snapshots before major edits
• Restore, duplicate, and manage saved sessions
• Copy or save the final draft as plain text
• Export a session package with embedded source snapshots
Row-aware composition:
• DiffDraft is careful about row structure while you work
• Source rows, draft rows, manual rows, and intentional gaps stay visually aligned
• Manual rows you add to the draft remain draft-only instead of being forced into a source lane
• Source lanes show the missing-source context instead of pretending every draft row came from a source
• Editing the Compose Draft is designed to avoid the row collapse and reshuffling that can make long text reviews hard to trust
• The final exported text stays clean, without row labels, UI markers, or provenance badges inserted into your draft
Built for real text workflows:
• Marketing copy and landing page revisions
• Contract clauses and policy text
• Documentation edits and release notes
• Prompt drafts and generated text review
• Markdown, JSON, YAML, CSV, XML, and code-like text treated as plain text
• Localization-safe review and wording comparison
• Personal notes, essays, scripts, proposals, and research drafts
Why DiffDraft is different:
• The Source Shelf keeps more than two versions close without turning the canvas into a cluttered N-way merge screen
• The Focus Canvas shows only Active Left Source | Compose Draft | Active Right Source
• The center draft is always the main object of value
• Source lanes are read-only in the Focus Canvas
• Taking a hunk changes only the Compose Draft
• Switching active sources does not reset the draft
• Source snapshots stay embedded in saved sessions so work can continue even if an original file moves
Local-first and plain-text first:
• Your text workflow stays centered on your Mac
• No account is needed to compare, compose, save, and export
• Source files are not silently modified by comparison or compose actions
• Final draft export uses the Compose Draft text, not UI markers or provenance labels
• Session packages make unfinished work portable when you choose to export them
DiffDraft is made for the moment when comparing changes is not enough. Use it to create the final version deliberately: review alternatives, choose strong passages, rewrite weak ones, save checkpoints, and export a clean final draft.
Compare versions. Cherry-pick the best parts. Compose the final text. Save the session and continue later.
