Souffleuse
A fully private writing aid for Mac that suggests the next words as you write
On-device AI writing assistant for Mac that suggests continuations in grey text under your cursor while keeping all text local and private.
About this launch
Souffleuse is an AI writing assistant for Mac that provides real-time text suggestions. When you pause while writing in any app—Mail, Notes, Messages, Safari, Slack, and most others—it displays a grey suggestion under your cursor. You can accept it with Tab, dismiss it with Esc, or keep typing to make it disappear.
The software runs entirely on your Mac using Apple Silicon, with no internet connection required after the initial setup. It learns your writing style over time, offers tone adjustment through a special "//' command, provides translation as you write, and fixes typos automatically. A usage ledger tracks keystrokes saved and time gained, all kept private on your device.
Souffleuse is built for people who write extensively throughout the day—email writers, support teams, multilingual communicators—who want writing assistance without their text leaving their machine.

Shopper questions
What leaves my Mac?
Day to day, nothing at all. The only time Souffleuse connects is at install to set itself up. After that, your text and everything it learns about you stay on your Mac, and it works even without an internet connection.
How much does it cost?
Souffleuse Studio is a one-time purchase: €29 with Lightning or €39 by card. There is no subscription and no daily quota—you buy a license, activate it on your Mac, and write.
How is it different from a regular spellchecker?
A spellchecker waits until you're done to underline what's wrong. Souffleuse does the opposite: it offers the next words before you write them, in your own tone, and learns from what you keep.
Which Macs are supported?
Souffleuse runs on Macs with a recent Apple chip (M1, M2, M3 models and later) on macOS Sonoma (version 14) or newer. Older Intel Macs are unfortunately not supported.
How does translation work?
You pick a conversation's language once and Souffleuse remembers it, then translates as the exchange unfolds in a small, quiet panel. Like everything else, translation happens on your Mac offline.
