The record

Product: Lastslate is a screenplay editor for Mac and Windows with an AI collaborator that reads scripts and does not write dialogue.
Formatting: The editor detects screenplay elements such as sluglines, character cues, and dialogue as the writer types and saves automatically.
File formats: Lastslate supports Final Draft FDX, Fountain, plain text, and PDF, including reconstructing editable scenes from PDF screenplays.
Companion Mode: Companion Mode watches a script file written in another editor, rereads it when saved, and operates read-only; asking it questions requires Pro or a user-provided model key.
Review links: Review links let recipients comment on script lines in a browser without an account, with threaded replies tied to a specific draft.
Co-writing: Pro supports live co-writing with up to 10 writers in one script at once.
Story planning: The Beat Board links story beats to script scenes and is included on every plan; Pro adds reference images on beats.
Script tools: Built-in skills include cast lists, location and prop breakdowns, loglines, and one-sheets derived from the script.
Privacy: Scripts are stored locally by default, cloud backup is opt-in and encrypted in transit and at rest, and the company says it does not use scripts, prompts, or completions to train AI models.
AI data sharing: When a user invokes an AI action, the relevant script excerpt, prompt, and session conversation context are sent to the AI provider for that request.
AI account options: Paid plan users can connect their own Claude, OpenAI, or Gemini account or a model running on their computer, with the key stored in the computer's keychain.
Windows support: The Windows app supports Windows 10 and 11 (64-bit), uses a code-signed installer, and updates automatically.
Mac support: The macOS app requires macOS 12 or later, supports Apple Silicon and Intel, and is notarized by Apple.
Maker: The privacy policy identifies Uniqlabs LLC as the publisher of the Lastslate application.
