Client-side PDF-to-M4B pipeline using OpenAI APIs and vendored Mediabunny for encoding.

Strengths
  • •Vendored Mediabunny enables AAC to M4B conversion entirely within the browser.
  • •Client-side retry logic handles API rate limits without backend infrastructure.
  • •Bring-your-own-key model avoids SaaS markup and data retention risks.
Weaknesses
  • •UI is admittedly atrocious, requiring manual CSS work for better usability.
  • •Requires OpenAI API key, creating a barrier for non-technical users.

Post Description

Used openai API to build a couple of serverless frontend webapps for making audio books for my pals over a weekend, and I thought I'd share. PDF to M4B- https://mstsirkin.github.io/bookworm-whisper/pdf.html Epub to M4B - https://mstsirkin.github.io/bookworm-whisper/epub.html

Japanese ma is the most underrated design system in front end

The visual concept is strong: generous negative space, a micro-typographic centerline and restrained UI that actually sells the idea of 'ma'. Unfortunately the page reads like a demo/theme — repeated copy blocks and zeroed stats suggest placeholder content rather than a finished system or component library. Useful as a quiet starting point for designers who like minimalism, but it needs real docs, components and examples to move beyond a pretty landing.
