Lastslate vs Plotwell

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.

Plotwell is a browser-based platform connecting screenplay development with storyboarding, production planning and budgeting. Its studio includes logline, synopsis, treatment, character breakdown and pitch-deck documents, plus a development agent. The screenplay editor formats script elements and supports Final Draft and Fountain import and export, along with PDF export. AI tools can generate scenes, brainstorm, rewrite dialogue and insert text using project context; Script Doctor analyzes pacing, act breaks, structure, character consistency and dialogue patterns. Storyboards can generate AI panel images from scene descriptions, while production tools extract cast, props and other elements, assign shoot dates and locations, and generate call sheets. Budgeting covers category and line-item costs, over-budget alerts, calculations and PDF or CSV export. The free plan is free and includes one project, one collaborator, 10 AI credits, all features and version history for the last five saves. Additional projects and collaborators each cost $3 a month. AI credit packs cost $5 as a one-time purchase for 200 credits, $10, paid once for 500 credits, or $20, paid once for 1,400 credits.
