Laper
From first draft to final cut. The only platform where screenwriters and AI collaborate on scripts, breakdowns, storyboards, and production.
On Laper
Laper is a browser-based AI screenwriting assistant that keeps the script at the center of every task. It formats Hollywood-standard screenplays automatically, visualizes structure as cards and tables, and lets writers, directors, and producers collaborate on one live draft. Character, location, and beat data are derived from the script and reused across outlines, storyboards, and production boards without duplication. AI tools operate on explicit screenplay nodes rather than raw text, and generated assets like character portraits or storyboard frames are stored as project entities with built-in credits and refunds.
Laper is the rare AI screenwriting tool that actually respects the craft. Instead of an open-ended chat that rewrites your dialogue, it gives you structured AI that works on screenplay nodes and keeps formatting correct. The real-time collaboration and script-derived production assets are genuinely useful for indie filmmakers and writers’ rooms. The catch is that the good stuff is behind a paywall, and the free tier is quite limited. If you’re serious about screenwriting and willing to pay, it’s a focused, thoughtful alternative to generic AI writing tools.
