Plain text, placed in time.

Write it down.
See it on your calendar.

NoLen finds dates and times in everyday writing,
keeps your note unchanged, and sends only the schedule to your calendar.

NoLen is a local-first note app where your thoughts stay in ordinary, readable text.

A NoLen note about weekend plans, with schedule suggestions below the text.

Notes never needed more rules.
They needed better connections after you write.

How it works

Write. Review.
See it in time.

Your everyday writing becomes the starting point for your calendar.

  1. 1

    Write in your own words

    “See the exhibition tomorrow at 10 AM.” Write things down in the order they come to mind—no date field required.

  2. 2

    Review each suggestion

    Check the date, time, title, and type before adding it. NoLen never confirms a schedule without you.

Plain text stays plain

Your note stays
a note.

Finding a schedule never rewrites your note. No hidden markers. No proprietary formatting.

Your writing remains the source of truth. Dates and schedule details are stored separately, so you never have to change how you write to use the app.
