Hold a key.
Say it. It's typed.

Your voice becomes clean, finished text in any app on your device — in any language, even two languages mixed in one sentence. Fillers removed, punctuation placed, your words kept.

✓ Cleaned up

99 languages · one setting

Your native language and English —
in the same breath.

Say the sentence the way you'd say it — Semoru keeps each word in its own script. Flip one setting and it translates everything into whatever language you want, as you speak.

how it works

Your voice, in every app,
already cleaned up.

Hold ⌥ and talk

One key, anywhere on your device. Ramble, pause, switch languages mid-sentence — just talk like you talk.

Watch it clean

Fillers, repeats and false starts vanish. Punctuation lands. Your history keeps the raw take, always.

It lands at your cursor

Slack, Gmail, your editor, a comment box — no plugins, no paste. Release the key and the text is there.

⌥ option

per-app style

Sounds like you,
everywhere.

Casual in Slack, proper in Gmail, untouched in your code editor. Semoru learns the surface of how you write — greetings, emoji, sign-offs — and never rewrites what you meant.

spoken commands · snippets

Structure, undo and saved text — by voice.

"new line" shapes it. "scratch that" undoes it.

hi Rahim new line the first cut is ready new paragraph ~~we deliver Thursday~~ scratch that we deliver Monday

Hi Rahim, The first cut is ready. We deliver Monday.

Say two words, paste a paragraph.

courier please, deliver to my address before noon

Courier please, deliver to 12 Rue Cler, Paris 75007 before noon.

Addresses, meeting links, sign-offs — anything you repeat but never want to spell out loud. Works in any language you dictate in.

privacy is architecture

Built like it's listening to everything — because it is.

A dictation tool hears your work, your names, your numbers. That demands more than a policy page.

On-device by default

On Apple silicon, speech becomes text on your Mac. Airplane mode? Still works.

Zero retention, in code

When the server is used, audio streams into memory, is transcribed, and the buffer is freed. No disk, no logs. Transcripts live only on your machine.

No third-party AI vendors

Open models on our own servers. Your words are never routed to an AI company's API.

You can watch it

A live log in the app shows every request: what was sent, how large, which region. It's usually empty.

Screenshots — never

Semoru cannot see your screen. Not a setting. Not a toggle. Absent.

uh hi so about the invoice thing umm

Hi — about the invoice: sending the corrected one within the hour.
