Drop in the file. Studio transcribes it right in your browser — nothing uploads — then drafts your show notes, chapter markers, SEO copy, and social clips. One page. About two minutes. A couple of cents.
Bring an episode and an Anthropic API key. No account, no upload, no waiting list.
Drag in the audio — M4A, MP3, WAV, whatever your editor exports. It never leaves your machine: transcription runs locally in your browser.
The transcript writes itself in front of you, timestamps and all. Keep the .txt and .srt for your archive — they're yours, one click.
Show notes, chapters anchored to real timestamps, an SEO title that actually fits the box, and five quotes your hosts actually said.
Whisper runs inside your browser tab. Your audio never touches a server — ours or anyone else's.
Bring your own Anthropic API key. It goes only to Anthropic, straight from your browser. We never see it, never store it.
No accounts, no uploads, no databases. Close the tab and it's like you were never here.
We couldn't listen to your episode if we wanted to.
Studio shows you the actual token count and actual price of every generation, straight from the API response — no estimates, no bundles, no surprises at the end of the month.
These are real numbers from a real 22-minute episode, measured in July 2026. Your API costs, paid directly to Anthropic on your own key, land around a couple of cents per episode.
console.anthropic.com → API Keys. It's separate from a Claude.ai login; add $5 in credits and you're set for a very long time.
M4A, MP3, WAV, AAC, OGG, FLAC. First run downloads the transcription model once (~145MB), then it's cached forever.
Chrome or Edge on a recent Mac or PC flies — a 22-minute episode transcribes in about 2 minutes. Older machines take longer but get the same result.
If it saves you an afternoon, tell us. If it stumbles, definitely tell us — that's what the beta is for.
