LinguaVox is a Chrome extension that removes the language tax from your daily work. Speak naturally in your native language — LinguaVox transcribes via OpenAI Whisper, translates to any of 21+ target languages, and inserts polished text directly into whatever web field you're typing in. No copy-paste, no app switching, no grammar anxiety.
Works in Gmail, Slack, Notion, Jira, Asana, Salesforce — any website with a text field. Free tier includes 20 requests/day with zero setup. Power users and teams can bring their own OpenAI key for unlimited usage.
v3.0 — Meeting Mode: real-time translated subtitles for Google Meet, Zoom, Teams, and any other browser-based call. Tab audio captured via Chrome API → streamed to Deepgram → subtitles appear as a floating overlay. Requires explicit consent on first use.
Before LinguaVox: open a separate app → record → copy → switch to browser → paste
After LinguaVox:
1. Click any web field (Slack, Gmail, Notion, Jira…)
2. Hold Ctrl+Space → speak
3. Release → text appears within ~3 seconds ✓
No copy-paste. No switching apps. Works on any website.
