What is Trevor AI?

Trevor AI is an open-source daily planner that uses artificial intelligence to help you schedule tasks into your calendar based on time-blocking principles. Rather than letting your to-do list sit as an unorganised collection of items, Trevor analyses your tasks and automatically assigns them to specific time blocks in your calendar, taking the friction out of planning your day. The tool is designed for people who want a more structured approach to their day but find manual scheduling tedious or overwhelming. It works by understanding your tasks, estimating how long they'll take, and fitting them into your available calendar slots. This approach helps reduce decision fatigue and ensures you actually have time allocated for the work that matters. Being open-source means you can inspect the code, modify it to suit your needs, or host it yourself if you prefer not to use a hosted version.
