Introducing the F-1

Grow a computer that works while you sleep.

fern.computer is a personal harness — memory, skills, a council and a night shift around the models you already use. On your machine. With your keys.

01  What a harness isEngine & workshop

A model is an engine. A harness is the workshop around it.

Left alone, a model forgets you the moment you close the window, waits to be asked, and answers on its own. Put it in a harness and it remembers, works to a schedule, and argues with itself before it decides anything that matters.

02  Expansion modulesFitted as standard

Four modules, all fitted as standard.

Each one slots into the back of the F-1. None of them is optional; that is rather the point. Together they turn a clever engine into something that knows you.

Memory

It remembers what you told it in March, and why it mattered.

Skills

Teach it a procedure once; it runs it the same way every time.

Council

Several models from different labs argue before it commits to an answer.

Night shift

What you queue at dusk is done, checked and waiting by morning.

    It lives with you.

    Your machine or your cloud. Your API keys. Plain files you can read. Export everything, and leave whenever you like.

    Fig. 9  Three commands: read all of it, take all of it, leave.

    One folder, and it’s yours.

    Everything the F-1 knows is a plain file in one folder, on your machine or a cloud you rent. Type *CAT to read the lot. Type *EXPORT to carry it off. Type *BYE and it’s gone; there is no account to close.

    Your API keys stay on your machine. You pay the labs directly, and swap any model out when a better one comes along.

    06 · Service manualCommon questions

    Read before planting.

    What is a personal harness?

    The software around an AI model that gives it memory, procedures, a schedule and a second opinion. The model does the thinking. The harness decides what it remembers, what it may do, and when it works.

    How is fern.computer different from a chatbot?

    A chatbot starts every conversation from nothing and stops when you close the tab. fern.computer remembers what you’ve told it, keeps working overnight, and has a council of models from different labs check important answers before you see them.

    Which AI models does it use?

    Whichever you choose. You bring your own keys, pay the labs directly at their prices, and can swap a model out without losing anything the harness has learnt.

    Where does my data live?

    On your own machine, or a small cloud computer you rent. Everything is plain files in one folder that you can read, copy or delete. There’s no account to close, because there’s no account.

    What does the night shift do?

    You queue jobs at dusk: some research, a draft, a tidy-up of last week’s notes. It works through them while you sleep, checks its own results, and leaves a note by morning saying what it did and what it couldn’t.

    Is fern.computer available yet?

    Not yet. It’s still growing, slowly and on purpose. Join the waitlist and we’ll write when there’s something to plant.
