Anything, read aloud
An audiobook of whatever you're curious about. Ask your AI to read anything aloud — an article, your notes, the answer it just wrote — and oto saves it to your library: yours to play, share, and come back to, like a podcast feed you write yourself.
Hear it — a real episode from an oto library:
How it works
In Claude, open Settings → Connectors → Add custom connector and paste
https://oto.audio/mcp. Two minutes, free.
Paste an article, drop in your notes, or just ask a question and have the answer narrated. Pick one of 19 voices, or let it pick.
The player appears right in the conversation, and the audio lands in your library forever. Nothing expires, nothing regenerates.
Is this for you?
You ask AI things all day. Now every explanation becomes a listen for your walk — a deep dive on peptides, GPS, game theory, whatever this week's rabbit hole is.
When reading won't stick — ADHD, dyslexia, tired eyes — listening often does. Turn required reading into audio you can absorb anywhere.
Articles and newsletters pile up faster than you read them. Have them read aloud and play them like podcast episodes while you cook, commute, or train.
Why oto
Text-to-speech apps read to you, then forget. oto is a place your audio lives.
Every audio is created a single time and stored permanently. Your library only grows — replay anything, years later.
Every audio gets a public page. Send the link to anyone — they press play, no account, no app.
Explore what other people are turning into audio. Follow them, dig into topics, build your own station.

Questions
Yes. With oto connected, ask Claude to read any answer aloud and you get a saved, replayable audio in your library — not a one-off voice that disappears when the chat ends.
Paste the article (or its link) into Claude and ask for it read aloud. oto turns it into an episode in your library that you can play like a podcast — while you cook, commute, or train.
Yes — 10 minutes of generated audio every month, no card required. Unlimited generation is $6.99/month, cancel anytime.
No. oto works inside Claude on the web and desktop. An iOS app is on the way. Just confirmed your email? Head back to your chat and reconnect — sign-in picks up where you left off.
Your library is private by default. Every audio has a share page that only people with the link can play — no account needed to listen.
