A to-do list that keeps up with you.

Neutrino is a to-do list for Mac built for the keyboard. Every action is one key, every key responds instantly, and your list is a plain text file that you own.

Neutrino's main list, showing tasks with labels and due dates

One key for everything

J and K move through the list. C writes a task, E finishes it, H sets a due date, L adds a label.

Due dates in plain words

Type tomorrow, 10am thu or 3 days and Neutrino works out the rest, even before you finish the word.

Your list is a text file

Everything is saved as one markdown file of checkboxes. Open it in any editor, or keep it in a synced folder. No account, no subscription, nothing collected.
