Ideas and to-dos that don’t die in a notes app

Ideas and to-dos that don’t die in a notes app.

Dump everything in one place, as fast as it comes. Noteer sorts it out afterwards, asks only when it has to, and lets go of what you no longer need.

Updated 7 November 2026

In short

No filing: notes on one subject are grouped into lenses automatically, and you can undo any grouping.
Paste a pile and Noteer offers to split it into separate notes.
Duplicates and notes that continue older ones get a “keep one?” or “merge?” offer.
Day words become due dates; due notes come back in Urgent, on Day and in Catch up.
Three to-dos on one subject? Noteer offers to collect them into one checklist.
Notes untouched for 14 days fade; the weekly review keeps what matters.

Start with everything you already have

The first time you sign in, a short interview offers “Bring a few notes”: paste what is sitting in another app, and Noteer splits it by paragraph or line into up to 40 notes, skipping the ones it already has. The agent reads them like anything you write.

Sorting without folders

You never choose where a note goes. When three notes share a subject, the agent makes a lens for them; new notes about it are filed there. Each note gets a handle (PRC-2) you can write in other notes, and the Map shows how they point to each other. You can rename, remove or ask for a lens yourself (“everything about pricing”).

To-dos that come back

Write “send the deck Thursday” and the note is due Thursday. Due notes gather in Urgent and on Day. When a date slips, Catch up asks once: Move to today, Drop the date, or Not now. There are no push notifications yet; Noteer is where the reminder waits.

Checklists that hold notes

A list you write or say gets a checklist offer. Three or more open to-dos on one subject get “collect them into a checklist?”: the checklist’s items are those notes, and ticking an item marks its note done everywhere it appears.

Letting go

Most ideas don’t deserve to live forever, and a list that only grows stops being read. A note nobody touches for 14 days fades out of your list. Once a week, the review shows what faded: tap the ones to keep, and the rest go to the archive. Nothing is deleted unless you delete it.

Ask across everything

“What did I want to change on the price page?” Chat answers from your notes, across lenses, and shows the notes it used.

Questions

What are lenses and handles?

A lens is a group the agent makes when several notes share a subject, for example “WAT · Waterside”. A note in a lens gets a handle like WAT-3, and every note also keeps a permanent number like N-45.

A mention of a note always shows its current handle, so references never go stale. You can rename or remove a lens, or take a note out of one; the agent won’t put it back.

Does Noteer send reminders?

Not as push notifications yet. A reminder sets a due date, and the note shows in Urgent, on Day and in Catch up when it is due. Notifications are on the roadmap.

Does Noteer delete old notes?

No. Notes nobody touches for 14 days fade out of sight into Fading, and a weekly review lets you keep what matters and archive the rest. Archived notes stay in Noteer.

Only you can delete a note, with Delete forever: the note, its history and the agent’s data about it are removed from every device.

What is Catch up?

The one place where the agent asks for things: overdue dates, guesses, questions about names it can’t place, proposals and the weekly review.

Yellow in Noteer means “the agent needs you”, and nothing else is yellow. Your notes, your day and the map never nag.
