One-line prompt turns Opus 5.5 into an App Icon designer via JS Canvas
dotey · x · 2026-09-27
dotey shares a practical trick for designing App Icons with Claude Opus 5.5: earlier attempts with Fable and ChatGPT fell short, and ChatGPT output wasn't vector. Inspired by Opus 5.5 drawing videos frame by frame with JavaScript + Canvas, he asked it to draw icons the same way — a single one-line prompt produced results beyond expectations. The key is requesting "draw with JS canvas" instead of SVG, which yields noticeably worse results. Iterating on a chosen version works like giving client feedback.
The linked page also introduces BaoCut 2.1, his Mac app for subtitles and video: an AI agent that runs real workflows (fetch, transcribe, translate, align, verify) via Claude Code or Codex, on-device speech recognition with no AI account needed, bilingual subtitles with per-line timing and reading-speed checks, and same-voice dubbing into other languages, with SRT/VTT/ASS export.
