Lastslate vs ScriptDraft

Lastslate is a screenplay editor for macOS and Windows with an AI collaborator that reads scripts but does not write dialogue. As a writer types, the editor identifies elements such as sluglines, character cues and dialogue, and saves automatically. It supports Final Draft FDX, Fountain, plain text and PDF, and can turn PDF screenplays into editable scenes. The Beat Board links story beats to script scenes and is included on every plan; Pro adds reference images to beats. Built-in tools derive cast lists, location and prop breakdowns, loglines and one-sheets from a script. Browser review links let recipients comment on script lines without an account, while Pro allows up to 10 writers to co-write one script live. Scripts are stored locally by default, and optional cloud backup is 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, Beat Board, PDF and FDX export, 10 cloud projects and limited AI collaboration. Pro costs $15 a month; Pro+ costs $45 a month.

ScriptDraft is screenplay software for writing, formatting, and exporting scripts on Android and iOS phones. Its cloud AI can turn a scene description into formatted Fountain screenplay text and organize spoken or typed ideas into scene headings, action lines, and dialogue. Writing, editing, and formatting work offline, while AI scene improvement and cloud translation require an internet connection. The app supports writing and voice recording in more than 100 languages, plus offline Romanized-to-native transliteration for 15 Indic abugidas. Export formats are PDF, Fountain, and Final Draft FDX. Free PDF and FDX exports carry a small ScriptDraft watermark; Fountain exports do not. The site says phone speech recognition processes audio on-device and does not upload audio to its servers. The free plan is listed at free, with no trial or expiry, and no account is needed to start. Pro is listed at $3.99 a month or $29.99 a year and includes 30 voice takes and 300 AI credits per month, cross-device sync, tablet layouts, and iCloud and Google Drive backup. One-time voice packs are also listed, from $2.99, paid once.
