Technical docs
How the apps
are built.
Architecture, data, security and AI for each app, written for developers and for anyone who would rather check a privacy claim than trust it. Every page describes what exists today; plans live on each roadmap.
Storyline
How Storyline is built: a private writing studio with no backend, AI that stays on the device for privileged work, one observed door to the web, and a log you can verify.
Tasker
How Tasker is built: a headless task engine, a planner that always answers, an agent platform with one policy gate, and an MCP server, all running on your own devices.
