Souffleuse is a typing assistant for macOS. It shows ghost text under your cursor the moment you look for your words, then fades away. Tab accepts it, Esc dismisses it. It works wherever there is a text field: Mail, Notes, Messages, Slack, Safari, Chrome, Obsidian, Bear.

Text is generated on-device by llama.cpp. No network at runtime, no account, no tracking. About 7.5 MB, notarized by Apple. Free to download, Souffleuse Studio is a one-time purchase from 29 EUR. Requires macOS 14+ on Apple Silicon.
