Lastslate review
A capable screenplay workspace for teams that want multiple AI providers and co-writing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Lastslate is a desktop screenplay editor for Windows and macOS, built for screenwriters, development teams, and professional co-writers. It combines format-as-you-type editing with Final Draft-compatible pagination, screenplay analysis, beat planning, named parallel drafts, version history, review links, and optional cloud backup. Its AI collaborator analyzes scripts, tracks story elements, and provides notes without writing dialogue, while extraction skills cover cast, locations, props, loglines, and one-sheets.
The free plan costs $0 per user per month and includes the full editor, screenplay pagination, PDF and FDX export, Beat Board, 10 cloud projects, 30-day version history, and a limited AI collaborator. Pro costs $15 per user per month when billed monthly or $150 per user per year when billed annually. It adds extended AI collaborator limits, advanced models, AI scaffolding, review links, unlimited cloud projects and version history, and real-time co-writing. Pro+ costs $45 per user per month or $450 per user per year and includes three times the included AI of Pro alongside the same paid features. A 14-day free trial is also listed.
Its strongest fit is collaborative screenplay development across multiple AI ecosystems: Claude, OpenAI, and Gemini are supported, and paid plans add browser review links with line comments and threaded replies. The Beat Board links to scenes, while parallel drafts and version history support structured iteration. The product remains focused on screenplay work rather than general script types, and its AI role is analysis and scaffolding rather than dialogue rewriting. Choose Lastslate if screenplay formatting, portable workflows, version control, and multi-writer collaboration matter. Choose another tool if direct AI dialogue rewriting is central to the workflow.
