Lastslate vs SenEDIT

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.

SenEDIT is cloud-based web software for writing screenplays and organizing filmmaking workflows. Writers can choose International (Hollywood) or French templates, then work with fields for location, setting, time, action, character, dialogue, parentheticals, and sound. SenEDIT Basic also includes treatment notes and screenplay statistics. Scene cards come from the first six lines of each scene and can be copied or reordered. Screenplays can be filtered by location, time, setting, character, and sound; scripts written elsewhere can be pasted into the workspace. Users can exchange screenplays with other SenEDIT users and export them as PDFs. The service describes AI help for synopses, stories, scenes, dialogue, and storyboards, in limited form for SenEDIT-A users. Turkish and English are available, while screenplay development is independent of interface language. Basic costs nothing, allowing 10 screenplays and 50 MB total storage.
