Hi Product Hunt, I kept sitting in English meetings where a word I didn't know would go past, and I'd tell myself I'd look it up later. I never did. The meeting ended, the word was gone, and the next call had its own. So I built CallVocab. Your call already generates live captions — CallVocab mirrors them into a side panel where every single word is clickable. Tap one and you get its meaning and pronunciation, and it's saved automatically together with the sentence it appeared in. A word without its context is a word you forget twice. After the call you review everything as flashcards, grouped by meeting, and you can export it all to Anki, Notion, Markdown or plain text. Two decisions I care about: It's free with no account, no sign-up and no API key to paste. Your words and transcripts are stored in your own browser, never on a server of mine — because a transcript of your work meetings is not something I want to be responsible for. And it doesn't do speech recognition. It reads the captions the platform already provides, which is why it's light and why live captions need to be on. Google Meet and Microsoft Teams work. Zoom doesn't, because Zoom only shows captions in its desktop app and no browser extension can read a desktop application. I'd genuinely like to know where it falls short. If you try it in a real call and something breaks or feels wrong, tell me here — I'm around all day.
