Laper

Laper is an AI screenplay editor that auto-formats scripts, turns scenes and characters into a visual outline, lets an AI Script Doctor flag structural weak points, and keeps a whole writers' room synced on one draft — all without an AI ever deciding what a character says.

Core Features

• Automatic screenplay formatting — industry-standard margins, Courier 12pt, and all six script elements, with both Hollywood and Asian layout modes handled automatically.
• AI script workspace — ask the AI to inspect the current focus, outline, a selected scene or range, or the full draft; its tool calls operate on screenplay nodes and storyboard context instead of raw text.
• Script structure visualization — scenes, characters, and locations are parsed directly out of the script and shown as outline, cards, tables, and production canvases.
• Real-time team collaboration — Loro CRDT keeps writers, directors, and producers on one synced script state, with saved version history.
• AI production assets — character portraits, location references, prop images, and scene stills are generated and stay attached to the entities that requested them, instead of floating as loose files.
• AI automatic storyboard — select a scene and Laper drafts shot structure, prompts, and storyboard frames, using the scene's own script text as context.
• AI Script Doctor — maps the full outline, flags the scenes the story structurally depends on, and returns notes prioritized by scene, character, conflict, and theme, rather than rewriting dialogue directly.

Who It's For

• Solo screenwriters who want formatting and structure help without handing over their own voice.
• Writers' rooms and showrunners who need one shared script state instead of emailing drafts back and forth before a sync meeting.
• Script editors who need to spot a structurally weak stretch of a draft quickly, before a full rewrite pass.
• Writer-directors and writer-producers who want scene, character, and production references to carry forward past the script stage.

What Users Say

"Finally, AI screenwriting software our whole writers' room can use without asking which draft is real. One script, live comments, the same AI diagnosis. Monday sync got forty minutes shorter." — @zero_draft.exe, Showrunner, Static Eden

"Most AI screenwriting software is in a hurry to write for me. Laper reads the full draft, tracks character pressure, and points to the beat that stopped working. It still leaves the pen in my hand." — @violet_cut, Writer-producer, Ghost Radio Kowloon

"The structure view exposed my dead middle in five minutes. I knew exactly which scene to cut." — @proxy_muse, Script editor, Midnight Rail 404

What Makes Laper Different

Most "AI screenwriting" tools try to write the story for you. Laper's own tagline — "AI Screenwriting Software, Without the AI Aftertaste" — draws the opposite line: AI handles formatting, structure, and diagnosis, never the story or dialogue itself, a boundary grounded in the founder's own screenwriting background. Laper also publishes its own screenwriting-craft guides — on script format, three-act structure, and the Save the Cat beat sheet — rather than only product marketing, which fits the same "assist the craft, don't replace it" stance.

Screenplay Community

• A project only appears in the public library after the author explicitly publishes it; private and invite-only projects are excluded by default.
• Signed-in readers can comment on and like published scripts.
• A public script can be remixed into a private copy, but remixing never grants edit access to the original project.

Founder Story

CEO Zhao ChunXiang describes himself as a screenwriter who didn't make it, before becoming a developer who built "many projects, big and small — still unsuccessful," until an AI app finally did well enough to fund Laper. He has said that if one of his own scripts is ever produced, Laper will become free forever — a specific promise, not just a mission statement.
