Worth knowing
Celtx
- The Free plan allows 1 project, with read-only script history and no commenting or collaboration.
- Production planning tools cost extra on Writer and Writer Pro and are only included from the Team plan.
- Team is priced for a group of 3 to 15 members rather than as a single seat.
- The download page links the mobile Celtx Screenplay app on Google Play and the Microsoft Store only, with no iOS App Store link.
WriterDuet
- The Free plan is limited to three projects of one document each, and free users can add only read-only collaborators.
- The desktop app and offline writing with auto-sync are listed from the Plus plan up.
- Revision tracking and production tools start at Pro, and full line and document history is Premium-only.
- Cards cannot be edited or rearranged in the mobile app or in phone and tablet browsers; WriterDuet recommends a computer for them.
Key features
Celtx
- Script editors
- Auto-formatting editors for film and TV screenplays, stage plays and two-column A/V scripts are included on every plan, including Free.
- Story development tools
- A Beat Sheet, a Storyboard, shot lists and talent sides help plan a script. They are included from Writer Pro and sold as an add-on to Writer.
- Production planning
- Script breakdown, catalog, scheduling, cast and crew, budget, call sheets and production reports are included on Team and are an add-on for the writer plans.
- Collaboration and approvals
- Comments are anchored to script text with @mentions, presence awareness shows co-writers' cursors and edits in real time, and scripts can be sent for review and approval.
- Script history, drafts and read-through
- Restore earlier saves from a dated history, keep editable draft copies of a script, and play lines back with text-to-speech voices.
- Revision Mode and episodic projects
- Revision Mode locks a script for production so scene numbers are preserved through changes. Episodic projects link scripts across the installments of a series.
WriterDuet
- Real-time co-writing
- Paid subscribers can invite any number of WriterDuet users, free or paid, to edit a script live, with comments, mentions and text and video chat.
- Script formats and templates
- Keyboard-driven formatting follows industry conventions for screenplays, stage plays, sitcoms and A/V scripts. Pro adds custom margins, line types and title pages.
- Cards, outlining and mind map
- Each scene can be viewed as a card and dragged into a new order, and a mind map view lets cards be placed freely and linked.
- Revisions and production tools
- Pro tracks revisions with accept and reject, shows deleted text, and adds colored revisions, locked pages and scene omission for scripts in production.
- Saving, history and backups
- Work saves to the cloud as it is typed, with automatic backups to a computer, email, Dropbox, Google Drive or iCloud. Premium can rewind a document or a line to any earlier point.
- Import, export and narration
- Imports and exports PDF, Final Draft, Fountain, Celtx, docx and other formats. Premium's ReadAloud voices each character, and AutoTranslate covers more than 80 languages.
