Tesseract
Agent.
AI that lives on your Mac. Dictation, speech, image generation, and a local AI agent — powered by open models, processed entirely on-device. No cloud. No accounts. Just you.
Everything runs on your Mac
Open-source AI models, optimized for Apple Silicon. No servers, no API keys, no subscriptions.
Voice Dictation
Hold a hotkey, speak, release. Your voice is transcribed and typed directly into whatever app you're using — a text editor, a browser, a chat window.
Text-to-Speech
Hear any text read aloud with natural-sounding voice synthesis. Consistent quality across long-form content, generated in real time on your Mac.
AI Agent
A local AI agent that can read, write, and edit files on your Mac. Interact by voice or text. Extensible through packages and plugins — all running privately on-device.
Image Generation
Create images from text descriptions using on-device diffusion models. No waiting for a server, no usage limits, no content filtering by a third party.
Your data never leaves your Mac
Every model runs locally on Apple Silicon. There are no servers to trust because there are no servers at all.
How it works
Download
Get Tesseract Agent from the Mac App Store.
First Launch
AI models download once on first launch. This is the only time the app needs the internet.
Grant Permissions
Allow microphone access for dictation and accessibility access for global hotkeys.
Ready
Everything runs on-device from that point forward. No internet needed.
