Real-time collaboration
WriterSolo never syncs to a server, so writing together means moving the project into WriterDuet. Inkwell co-writes live on the same project.

Inkwell vs WriterSolo
One writer and files on one device, or a screenplay with history and co-writers.
WriterSolo is WriterDuet's free app for one writer: no sync and no co-writing, with scripts saved as files on your own device, in the browser or a desktop app. Plot is for the script that picks up co-writers and versions. Every draft keeps named save points and parallel draft lines in one project, and writing together happens live in the browser.
WriterSoloStrengths
- Free for one writer on one device.
- A desktop app that writes with no connection.
- Scripts stay as WriterDuet or Final Draft files on your own device.
Where WriterSolo is strongest
InkwellInkwell edge
- Co-writers work live on the same project in the browser, and every change lands in one shared history. No files to email, nothing to merge by hand.
- Named save points and parallel draft lines keep every version of the script in one project, with the changes between any two shown scene by scene and line by line.
- A production pipeline on the same history: locked scripts, WGA revision colors, A-pages, breakdown reports and a submission preflight.
- Screenplay and genre expert skills: a dialogue pass, a continuity check, coverage, a horror pass, a romance arc, a fair-play check for mysteries and more, each proposing edits you accept or reject on the page.
- Inline AI on any line with Cmd+K, and Agent Mode for a whole scene or act, always starting from your screenplay and ending with your decision.

Version history
Inkwell names every save point and keeps it in one project history that co-writers share. WriterSolo never syncs, so whatever history it keeps stays on the device it was written on.

Semantic change tracking (scene/dialogue-level diffs)
Inkwell compares any two save points scene by scene and line by line, across everyone's work. WriterSolo has no shared history to compare.

Production revisions
Inkwell ties locked scripts, revision colors and A-pages to the save-point history the whole production shares. WriterSolo never syncs, so nothing it marks reaches anyone else on the production.
