Real-time speech-to-text with AI cleanup. Recognizes 11 languages. Add a Gemini API key to auto-polish your transcript.

Mamorukun turns your voice into clean, readable text right in your browser. ■ Two levels 📝 Transcription only (no API key needed) Real-time speech-to-text in the side panel. Copy or clear with one click. Works with zero setup. ✨ Transcription + AI cleanup (with a Gemini API key) When you stop recording, Gemini automatically cleans up the transcript — removing fillers, adding punctuation, and tidying spoken language into something you can paste anywhere. ■ Speaks your language Recognizes 11 languages: Japanese, English (US/UK), Spanish (Spain/Mexico), Chinese (Simplified/Traditional), Korean, French, German, and Portuguese (Brazil). You can keep the interface in one language and switch only the recognition language — useful for language learners who want to practice speaking and read back what they actually said. ■ What you need A microphone, an internet connection, and microphone permission on first launch. A Gemini API key is optional (only for AI cleanup). ■ Privacy Speech is processed through the Web Speech API (Google's speech recognition service). If you use a Gemini API key, the transcribed text is sent to the Gemini API for cleanup. Your API key is stored only in your own Chrome and is never sent to any external server.
