One box. It untangles the rest.
Write or speak a stream of everything you owe the day. Cerno turns it into titled tasks, each with a priority, an effort estimate, a deadline and a one-line reason — no key required to try it.
AI daily planner
Dump everything on your mind. Cerno decides what matters, estimates the effort, and hands you one realistic day — in order, with the rest quietly parked.

A to-do list only ever grows. Cerno reads the pile, weighs urgency against effort, and protects your day from itself — so you finish, instead of scrolling.
urgency against effort, recomputed as things land.
no fields, no tags. cerno reads the mess.



Write or speak a stream of everything you owe the day. Cerno turns it into titled tasks, each with a priority, an effort estimate, a deadline and a one-line reason — no key required to try it.
A capacity guard runs after the model: anything that pushes past your working hours is moved to tomorrow, whatever it was labelled. The top of Today explains the shape of the day in one honest line.
Whatever Cerno parses but doesn't schedule lands in the inbox, each row showing why it wasn't planned — and a single tap to put it on today.
Drag a task to another day, drop it into a time block, or postpone it to tomorrow. On a phone, press-and-hold — it never fights the swipe.
Cerno labels new tasks automatically — errand, comms, health, work. Filter by priority, deadline or label; search scans titles, labels and reasoning.
The bell collects what's overdue and what's coming up within your lead time. Overdue warnings don't dismiss — they clear when the task is done or moved.
A workspace is a shared list — up to 10 people. Assign tasks to teammates, invite by email or link, and let roles keep it tidy. You pay; the people you invite don't.
