Description

I was frustated by having to draw system design diagrams by hand when discussing it with my team mates or in an interview. So I thought "Wouldn't it be great if someone draws it for me, while I think out loud?".That is when I came up with VoiceDraw. You can just think out loud or discuss your system architecture with a friend/interviewer, the diagrams are automatically drawn along with your reasoning, open questions and tradeoffs beautifully written on to the side.Demo Video: https://youtu.be/36PgHKSuccE

Could you build this?

No Despite the description focusing on voice system design, the actual product described is a full browser-based After Effects competitor with bezier graph editors, 3D layer engines, expressions, and video compositing pipelines.

What it would actually take: Requires a high-performance graphics engine in WebGL2/WebGPU and WebAssembly (C++/Rust), implementing custom keyframe interpolation algorithms, expression sandboxes, custom font rendering, and multi-format client-side video encoding (WebCodecs/FFmpeg WASM). The hard part is building an interactive 60fps timeline and compositor with complex nesting and expression graph evaluation.

Concerns raised: No guarantee that prompts/transcripts stay local despite claims, Browser sandbox enforcement unclear for data privacy, Diagram output descriptions not useful for accessibility, Mobile response visibility issues, Connection/loading errors preventing tool from working

Feature requests: Typing interface in addition to voice input, Richer, screen-reader-friendly diagram descriptions, More visible privacy policy and local processing information, Better mobile response toast visibility
