# Laper

> Laper is script-first AI screenwriting software. It combines automatic screenplay formatting, explicit AI reading and editing tools, Loro CRDT project synchronization, story planning views, and optional visual development while the screenwriter keeps creative authority.

## Verified facts

- The screenplay editor is the source of truth. Scene headings determine scene order and feed location entities; character cues feed character entities.
- AI reads explicit cursor, outline, scene, range, node, or full scopes. Full mode is bounded to 800 screenplay nodes and reports truncation; longer drafts use outline plus targeted scene reads.
- Approved AI screenplay edits execute through the active Plate editor and enter the normal Loro document path.
- Collaboration uses Loro plus a dedicated lorosync service. Screenplay blocks are the conflict boundary; this is not marketed as character-by-character merging inside one paragraph.
- Existing projects require an online server-first initial sync. An already-open project can retain pending updates during a transient disconnect and synchronize after reconnect.
- Supabase Realtime never synchronizes screenplay or CRDT data.
- AI media uses durable task and asset records. The API backend owns authorization, credits, status, retries, refunds, and persistence; the generation worker performs model calls and uploads.
- Public community discovery includes only intentionally published public projects. Authenticated members can comment, like, and copy when permissions allow; copying does not edit the original.
