Speech to Text
Click record and your spoken words appear as text in real time. Powered by your browser’s built-in speech engine — no audio leaves your device, no microphone data sent to us, no API key required. Send the transcript straight to Text-to-Speech to hear it back, or copy it anywhere.
Best for: voice notes, dictating emails or drafts, capturing ideas while cooking or driving, accessibility, fast transcription of short clips.
Audio is processed by your browser’s built-in engine (Google for Chrome, Microsoft for Edge).
No audio is sent to our servers.
Talk to Claude
Have a real conversation with Claude. Type or tap the mic to speak; Claude reads its reply back to you out loud. You use your own Anthropic API key — fractions of a cent per chat — and messages go straight from your browser to Anthropic with nothing passing through our servers.
Best for: brainstorming on the go, research questions, hands-free help while cooking or commuting, voice-first work for accessibility.
Messages go directly from your browser to
api.anthropic.com using your own API key.
Nothing passes through our servers. Chat history exists only in your browser’s memory.
Your API Key & Settings
Store your Anthropic API key once, here in your browser. Voice Chat and Companion Mode use it to talk to Claude on your behalf. Text-to-Speech and Speech-to-Text are free and don’t need a key. The key is saved only in your browser’s localStorage — never on our servers — and travels only to api.anthropic.com.
Don’t have a key? Sign up at console.anthropic.com — new accounts get free starter credit, then it’s pennies per conversation.
🔒 Your Privacy Guarantee
