Your browser, by voice
Say a whole errand in one breath. Each step runs in your browser while you watch, and you can stop it with a key press. Buttons that send, buy or delete wait for your “yes”, and only your own voice can click.
SpeakFish types what you say into any app, runs your apps by voice, reads things back to you, chats with you as a goldfish and remembers your day. Speech is transcribed on your Mac.
Turn your sound up. Yes, there is an opera.
Hold §, talk however it comes out, let go. The ums, false starts and repeats go; the meaning stays. The text lands in the field you started in, even if you switched windows, and fits where it's going: a prompt for Claude Code, an email, a chat message.
hold it (or your § / ` key)
Say “SpeakFish, let's chat” and the fish answers out loud. It picks from about 2,400 library lines, on your Mac, in well under a second. It can also book, move and check appointments.

“Open Figma”, “new tab”, “scroll to the bottom”. Any installed app by name, no setup. A local model on your Mac (d1) makes sure you were talking to the computer, not to a colleague.
SpeakFish, search the web for… and a card shows the answer with its sources, read aloud. It only searches when you ask by name.
Selected text, Claude Code's last answer or your day's summary, in a natural voice on your Mac. Say “stop” any time.
Every line labelled Me or Other, with the recording a click away. “Summarise today” turns it into a page. Quiet moments re-check each minute for a surer version.
Learn your voice once. In a café, other people's sentences are dropped before they're transcribed, and a denoiser removes the clatter.
“Screenshot this window to Claude” puts the picture in your coding agent's terminal, ready to send.
Switch languages by voice. Each gets its own speech model, so “oggend” stays “oggend”.
Your phone as the microphone, touchpad and screen for your Mac. Hold to talk from across the room. Pairs with a QR code, no ports opened.
“Show stats” floats live panels: CPU per core, GPU, memory, and what SpeakFish sees right now.
Doctor Mode records only while a visit is open. When it ends, names, numbers and addresses are swapped for placeholders on the Mac, and only then is the summary written.
In pilot with role-play visits. Get in touch if you run a practice.
Every product deserves an aria. Ours has a chorus about the keyboard tax.
SpeakFish, SpeakFish
Words come free
SpeakFish, SpeakFish
Set thoughts loose in me
No keyboard tax
No pause, no drag
Just SpeakFish
And the day flies back
Speech is recorded and transcribed on your Mac. Recordings and transcripts stay there.
Cleanup, summaries and questions you ask are sent as text, with zero data retention and no training.
Which command you meant, which reply the fish says, what's sensitive: a model on your Mac decides.
