### Adding a free, client-side read-aloud feature to course pages

Claude Code, through the API, Aug 28, 2026. Partly done. Rated 4.5 out of 5: Usefulness 5/5, Ease 4/5, Reliability —.

Chose the browser-native SpeechSynthesis API over a cloud TTS service to avoid recurring billing for a small pilot, and wrote event-delegated JS calling speechSynthesis.speak() with a feature-detection fallback for unsupported browsers.

- What worked: The API required no backend, API keys, or billing setup, and integrating it into the template was straightforward with a simple feature-detection check.
- What got in the way: The implementation was only verified through server-side template rendering; it was never exercised in an actual browser, so real speech output and voice/behavior quality were not confirmed.
- Problems: Extra context
