Voice to text app

Say it. Already there. Correct. Fast.

Hold a key to talk

Press your hotkey, speak, release. The text pastes straight into any field, in any app.

100% on device

Models run on Apple Silicon. No audio or text is ever sent off your Mac. Period.

Smart cleanup

A local LLM trims filler words and resolves self-corrections so the paste reads clean.

Lightweight by design

Sits in the menu bar, uses almost no CPU at idle, and barely touches your battery. It's always ready — you'll never notice it's there.

99 languages

Whisper understands 99 languages on-device, and the Parakeet model covers 25 European ones. All running locally on your Mac, no internet needed.

Full history

Every transcription is saved locally. Browse, search, and reuse anything you've ever dictated — all on your Mac.

Slide Casper OFF to see scary stories.
Never leaves the building
Your voice and transcripts are born on your Mac and they die on your Mac. Casper doesn't even own a passport.
Doesn't play favorites
Slack, Notion, your terminal, that one ancient app you refuse to retire — Casper pastes into all of them. No copy-paste gymnastics.
No fine print, promise
Most voice apps want your Wi-Fi, your minutes, and your email before they'll listen to you. Casper just wants you to type less.
Basically weightless
Runs on Apple Silicon and transcribes in under a second. Your battery will barely clock that Casper's even awake.
Talk until you're hoarse
No minute limits, no overage fees, no "you've used your free 10 minutes this month." Ramble away.
Casper never forgets (or tells)
Everything you've ever said or copied lives on your Mac, searchable forever. No account needed to remember your own thoughts.
