Today✓ Saved

Slept well. Coffee on the balcony before anyone was up.

Ideas for the garden: tomatoes along the fence, basil in the window box.

Remember to call the dentist, and finish [[Book list]].

Evening: long walk by the river.

Write today. Find it later.

Not another screenshot of the same window. The three things that make this yours: a daily page, the days you showed up, and a search bar that actually finds it.

01 — Daily note

One page. Today.

No title required. Type, walk away, it is saved. Flip to yesterday or last week — every day you had an account still has a page. Try writing in this one.
