Lastslate
Summary
Lastslate is a screenplay editor for Mac and Windows with an AI collaborator that reads scripts but does not write dialogue. It identifies screenplay elements such as sluglines, character cues, and dialogue as the writer types, and saves work automatically. The editor supports Final Draft FDX, Fountain, plain text, and PDF, including turning PDF screenplays into editable scenes. Its Beat Board links story beats to scenes and is included on every plan. Built-in tools can produce cast lists, location and prop breakdowns, loglines, and one-sheets from a script. Browser review links let recipients comment on lines without an account, and Pro allows live co-writing with up to 10 writers. Scripts stay local by default; cloud backup is optional and encrypted in transit and at rest. AI actions send the relevant excerpt, prompt, and session context to the AI provider for that request. The free plan includes the full editor, PDF and FDX export, 10 cloud projects, and limited AI collaboration. Pro is $15.00 USD per month; Pro+ is $45.00 USD per month.
Who it is for
Lastslate suits screenplay writers who want screenplay-specific formatting, planning tools, and optional collaboration on Mac or Windows. Writers considering AI features should note that relevant script context is sent to the AI provider when an action is invoked.
What is good
- Detects screenplay elements while typing.
- Supports FDX, Fountain, text, and PDF.
- Beat Board is included on every plan.
- Review links allow browser comments without accounts.
- Scripts are stored locally by default.
What to know first
- AI collaborator does not write dialogue.
- AI actions send relevant context to the provider.
- macOS requires version 12 or later.
- Windows support is limited to 10 and 11, 64-bit.
Verdict
Lastslate combines screenplay formatting with planning, review, and collaboration tools, including a free plan with core editing features. Its local-first default does not prevent AI requests from sending relevant script context to the provider.
