Show HN: VoiceBrainDump – voice-first idea capture, single HTML file, offline

I built VoiceBrainDump because I kept losing ideas. By the time I opened a notes app and started typing, the thought was gone.

This lets you tap, speak, and move on. No folders, no tags, no organizing upfront.

How it works: - Voice-to-text using Web Speech API - Ideas are saved to localStorage (no server, no account) - Keywords are extracted automatically and used to connect related ideas - After 7 days, old ideas resurface so you can keep or archive them

The whole thing is one HTML file (~2000 lines). No build step, no npm, no frameworks.

Built it in a weekend. Intentionally minimal — meant for people who think faster than they type.

Works on mobile too. Just open it in your browser.

Happy to hear why this is a terrible idea.
