It assists artists instead of replacing their creative judgment. **Is Laper free?** Yes. The Junior plan makes Laper free screenplay writing software for getting started: 60 daily refresh credits plus 2 script projects. Signup grants 300 bonus credits, no credit card required. **How does Laper's AI work?** Laper's AI reads your entire screenplay (200K+ tokens) as context. From that whole-script understanding, it supports AI script generation and production-ready assets on demand: character bios, relationship graphs, casting and film posters, character portraits, props, scene stills and storyboards, every artifact grounded in the full script. **Can teams collaborate in real-time?** Yes. Multiple writers can edit the same screenplay simultaneously. Conflict resolution is automatic via Loro CRDT (character-level merge), so changes never overwrite each other, online or offline. **How is Laper different from Final Draft, WriterDuet, or Celtx?** - vs. **Final Draft**: Final Draft is a local-file desktop standard for screenplay formatting. Laper is cloud-native with real-time CRDT collaboration, full-script AI context, and one-click AI asset generation that Final Draft does not offer. - vs. **WriterDuet**: WriterDuet offers cloud collaboration via session sync. Laper uses character-level CRDT merge (offline-tolerant) and adds full-script AI context plus a one-click AI generation suite (character bios, relationship graphs, posters, portraits, storyboards). - vs. **Celtx**: Celtx focuses on production scheduling and pre-production breakdown. Laper covers the screenplay editor side plus AI-derived production assets in one document model. **What screenwriting AI does Laper actually use?** Large language models fine-tuned for screenplay structure and dialogue. The AI consumes the whole script as context and understands story architecture (Save the Cat beats, Hero's Journey, three-act structure), enabling cross-scene judgment on character arcs, foreshadowing and beat continuity. **Does Laper support Mac and Windows?** Yes. Native Electron desktop apps for both, plus full functionality in any modern browser. --- ## Contact - Website: https://laper.ai - Email: support@laper.ai - Twitter / X: https://x.com/liangshizhi - Discord: https://discord.gg/UgUNCawXkW - GitHub Discussions: (community) --- ## Comparison Pages (Laper vs Competitors) (6) Detailed comparisons between Laper and major competitors.
