Description
I’ve spent the last year getting back into film and testing a bunch of screenwriting software. After a while I realized I wanted something different, so I started building it myself.The core text engine is written in Rust/wasm-bindgen.

Could you build this?
Partial A web-based screenwriting UI can be built with AI, but maintaining a real-time collaborative text engine compiled from Rust to WebAssembly with exact pagination and industry formatting standards is complex.
What it would actually take: The architecture requires a Rust-based core compiled to WASM handling industry-standard Fountain/Final Draft pagination and layout rules, coupled with a CRDT engine (e.g., Yjs or Automerge) for real-time multiplayer collaboration. The challenge is ensuring pixel-perfect dynamic script pagination across varying devices without UI reflow lag while maintaining concurrent editing state. It demands expertise in Rust/WASM toolchains and distributed state synchronization.

Competitors mentioned: Final Draft, Tauri
Concerns raised: wasm-bindgen overhead for keystroke-level interactions in text-heavy apps, existing screenwriting tools are clunky

Nobody's really built a vertical saas tool for Insurance yet.
