Open one app.
It already knows.

Jackdaw is the app you open to your own brain. Mail, notes, journals, pages, tables and files, all in one window. Ask it anything and the answer comes back out of your own material.

Try the demoMeet the brain

The demo is the real app, on a read-only brain we filled in for you. Nothing to install.

A screen-printed jackdaw in profile on a fence post, in front of five bands of sunset colour, with wheat and an open gold field below.
A screen-printed writing desk by a window: an open notebook, a stack of sealed envelopes, a mug and a fountain pen, with a jackdaw perched on the corner and a round clock on the wall.

Everything you keep,
in one window.

Chat with it. Read your mail. Write a note, keep a journal, draft a page, build a table, park a file. Same window, same search, same memory behind all of it.

You stop hunting for the thing you know you saved.

Ask the way you would ask a person.

Everything that arrives gets read. Mail, notes, files, the lot. Not sorted into folders, read. So a plain question months later gets a plain answer, and it shows you what it read to get there.

It connects things too. Ask who somebody is and it can tell you where they turn up, what is true about them now, and what used to be.

Example

“What did we settle on for the gantry rebuild?”

Linear rails, decided on 20 March after the belt test failed. You capped the parts budget at four hundred.

A screen-printed twig nest holding a collection drawn in gold: a key, a ring, a coin, a bead, a button and a bottle cap, with a jackdaw leaning over to look at them.

It keeps working when you close the tab.

Jackdaw is the window. The brain behind it does not stop when you shut it.

A screen-printed jackdaw in full flight against bands of sunset colour, carrying a wax-sealed envelope in its beak over dark hills and two small rooftops.
Mail
A message from someone in your contacts is read, summarised and filed before you have seen it. Mail from anyone else is left where it landed.
Reminders
An event you put in the calendar reaches you as a message on your phone, at the time you asked for, with nothing open.
Errands
Ask for a piece of research before bed. It arrives as an email in the morning, sent from your own address, with its sources.

You do not have to remember to ask.

Yours, in the boring literal sense.

The brain runs on your own machine. Jackdaw keeps nothing: no database, no session secret, no server code of its own. It talks to your brain and to nothing else.

Every key and password stays sealed on your box. There is no account with us, no tracking, and no third-party script on the page you are reading either.

The one thing that leaves is what you send to the model you chose. You pick which model that is, and it can be one running on your own machine.

A screen-printed stone and timber cottage with two lit windows and a stone chimney, a gold-leaved tree beside it and a jackdaw sitting on the picket fence.

There is a brain behind this.

Mantle is the system underneath: one Postgres, six layers of memory, an entity graph, and agents that do the work. It has a site of its own, and that one goes into detail.
