Trill
Your voice never leaves your device.
Turn your voice into useful writing with dictation and rewriting on your own device. Cross-platform development continues.
The problem
Every cloud dictation app uploads your voice to servers you don’t control — their privacy pages are promises about what happens to your audio after it arrives. And raw speech-to-text doesn’t adapt to where you’re typing: a terminal, an email, and an AI agent each need different treatment.
What it is
Trill runs the entire pipeline on the user’s own hardware: tap a hotkey anywhere on macOS, speak, and on-device models transcribe and clean the text before it pastes into whatever app has focus. A four-stop dial — Verbatim, Light, Medium, Heavy — decides how much of what you said gets rewritten, routed per app. There is no upload step to govern: turn off Wi-Fi and it still works.
Why Trill is different.
On-device speech processing is central to the product. Platform support and current data boundaries are explained on the Trill site.
Verifiability as a featurea published data boundary, a build gate that fails on undeclared network calls, and instructions for checking the claim yourself.
Straightforward product access, with purchase details confirmed on the Trill site before launch.
Purpose-built for dictating to AI coding agentswith guarded prompt restructuring that protects names, files, and numbers.
Inside the current build.
On-device transcription: the model ships inside the app and works fully offline
The four-stop dial: Verbatim, Light, Medium, Heavy rewriting, set per app
Per-app profiles with spoken overrides and window-title rules
Prompt shaping for AI coding agents, with a guard against dropped details
On-device translation between languages
No telemetry, and an offline license that keeps working
Who it’s for
People who dictate as part of how they work — writers, professionals, and developers speaking prompts into AI coding agents — especially the privacy-conscious.
