The Dream

A memory that grows and is never tidied gets worse: the same thing written twice, old decisions next to new ones, links that no longer lead anywhere. The Dream is the tidy-up: Cobrain finds, your AI fixes it with you.

How it works

Cobrain does the pre-dream, you dream with your AI.

At night, the pre-dream

At 4 in the morning in your time zone, when you have finished working, Cobrain goes through the notes you worked on: that week’s, or that month’s, as you choose. With no AI and at no cost it looks for notes that say almost the same thing as another one (old ones included), decision logs grown too long, [[links]] that no longer lead anywhere, empty notes. Notes nobody touched stay as they are. If it finds something it writes to you: «Remember to dream», with the list and the sentence to give your AI. It changes nothing: it only finds.

Every week, every month or never: you choose in the Brain settings (bottom left, the gear next to your initial). It starts at once a week, on Monday.

Whenever you like, «Dream now»

From the brain settings pick how many days back to look, from 1 to 15, and press Dream now. Or right-click a folder and choose Dream now: it looks at every note in the folder, of any age, up to 300 (beyond that, pick a sub-folder). You see the result straight away on the Dream page, with the sentence to copy, and it reaches you by email too.

The real dream, with your AI

Paste the sentence from the email into your AI connected to Cobrain:

Use Cobrain's Dream tool on the last 7 days and tidy up my brain with me.

Or tell it in your own words: «Dream on the last 10 days on Cobrain.». The AI uses the dream_tidy_up tool, tells you what it found and works with you: the obvious things (two identical notes to merge, a link to fix) it fixes on its own and tells you; for those where something could be lost (deleting a note, choosing between two decisions) it asks you first, with a numbered list. Answer «do it all», «do 1 and 3» or «not 2». Beyond 15 days it tells you how far it can go.

Every night, on its own

Claude and ChatGPT can repeat a task on a schedule, even with your computer off. You set it up once.

Claude (paid plans): in Cowork open Scheduled tasks → New task, paste the sentence below, pick the frequency (daily or weekly) and, as approval mode, Automatically approve: with manual approval the night-time task would stop and wait for you. The task uses your account’s connectors, Cobrain included.
ChatGPT: ask it to create a recurring task (Tasks) with the sentence below. ChatGPT, however, asks for confirmation before every write and the task pauses until you approve: in the morning you find the proposal ready, and you confirm.
Claude Code (for developers): Routines on claude.ai/code run in the cloud with the account’s connectors and write without asking. Same sentence.

Run the Dream on Cobrain. Fix on your own only the safe things (like a broken link with a clear destination); to merge, delete or touch decisions, write me a proposal in a note called «Dream – proposals» and wait for my yes.

The night-time sentence is cautious on purpose: on its own the AI only fixes what cannot go wrong, and prepares the rest for you. If you trust it more, drop it and use the one above. Claude’s and ChatGPT’s menus are often renamed: if you cannot find them, ask your AI «how do I create a scheduled task?».

Things worth knowing

What people usually ask.

The pre-dream is free and uses no AI: it looks at the names, words and dates of the notes you worked on. Working out what to do is your AI’s job, on your own subscription.
They are suspects, not errors: two similar notes can both be right. The AI reads them and tells you.
Nothing is lost: every changed note keeps its previous versions, a superseded decision is marked as such instead of disappearing, and the copy of a duplicate the AI deletes goes to the brain's trash, where you can restore it for 30 days. A note that is not a duplicate the AI does not delete without your yes.
The email goes only to the brain’s owner: it contains the names of the notes. Someone who received a branch does not get it.

Every command your AI has in Cobrain is on the tools page.
