In simple English

Cognate is a day planner that organises your tasks into time blocks automatically. It keeps all your data on your own device and encrypts everything so no one else can read it. You can connect it to local artificial intelligence models or use your own keys. It is free to use, but the software is still under active development and has some rough edges. You might need to troubleshoot installation warnings on your computer.

What it is

Cognate is a desktop and web task planner built with Rust, React, and Tauri. It features automatic time-blocking, end-to-end encrypted synchronisation, and local artificial intelligence integration.

What it is good for

Solo builders who want a private task manager that automatically schedules their day without sending personal data to the cloud.

Good
  • Keeps your data private and local on your machine.
  • Automatically turns a list of tasks into scheduled calendar time blocks.
  • Supports local artificial intelligence models through Ollama.
Watch for
  • Unsigned desktop builds trigger security warnings during installation.
  • Advanced features like live synchronisation and calendar OAuth need further validation.
  • Requires Node.js and Rust toolchains to build from source.
Replaces

manual time blocking in commercial calendar applications
