Carl
AI-native. Converses. Remembers. Yours.

Every shift made the computer more personal. Carl is the step where it becomes truly yours.

The idea

"The most remarkable tool we've ever built — not because it does the work, but because it multiplies what a person can do."

Steve Jobs called computers bicycles for the mind. bicycle.ai builds the next one.

The accountant who never coded. The photographer building her first website. The teacher who knows exactly what he needs but not how to get it. Carl is for them — not for engineers. A tool that makes any person more capable, without requiring them to become someone else.

The full picture

Not a chat window.
A thinking environment.

Carl is the computer. But more than that: a filter for the entire sum of available human knowledge — narrowed to what matters for what you are doing right now.

01

The knowledge funnel

The internet. Every paper. Every argument made. Carl filters it down to what is relevant to the thought you are currently thinking.

02

Connects your thinking

Your idea meets the ideas that came before it — across disciplines, across centuries. Carl finds the links you wouldn't have found yourself.

03

Creates for you

Websites for your campaigns. Proposals for your clients. Automations for the things you hate doing. Describe it. Carl builds it.

04

Organises as you work

"Create a folder for the Vienna workshop." Carl does it. Your files structure themselves around how your mind actually works.

Carl doesn't just answer questions. It connects your current thought to every relevant thought that came before it — and asks the questions that sharpen yours.

The interface

Your computer. Your rules.

Carl's interface isn't a setting buried in preferences. It's a living surface. Say what you want — Carl reshapes your entire computing environment. Say nothing — and it stays exactly as you left it.

Projects

Every project. Its own room.

Your photography project. Your client work. Your side business. Each one is a separate room — its own context, files, and memory. Carl knows exactly where you left off. Switch by voice or by click.

Who uses Carl

A bicycle for any mind.

Not for engineers. Not for the technical. For anyone who thinks, creates, manages, builds — and wants a tool that multiplies what they can do. Carl is for everyone. But your Carl is built for exactly you — it learns over time what you need, how you think, and what to bring you next.

Photographer
Books shoots, briefs clients, builds her portfolio site. Carl knows every project, every client, every brief.
After a year, Carl knows her clients better than her notebook does.
Philosopher
Her argument meets Kant and Nietzsche. Carl finds where they'd agree, where they'd push back, which paper from 1923 already tried this and why it failed.
After six months, Carl knows how she thinks.
Archaeologist
Uploads a fragment. Carl cross-references 3,000 comparable finds, filters the relevant literature, and surfaces three connections no one has drawn yet.
Over time, Carl becomes a second specialist.
Teacher
Prepares lessons, researches deeply, generates materials. Offline. Private. Everything stays in the school.
By year two, Carl knows the curriculum better than the curriculum.
Consultant
Proposals, reports, six clients — all in separate rooms. Carl knows each one's history. Forgets nothing.
After a year, Carl recalls every client conversation in detail.
Architect
Project documentation, precedent research, reference libraries. Carl organises as the work grows.
Over time, Carl becomes the firm's institutional memory.
Founder
Landing pages, pitch decks, investor emails. Carl does in an hour what used to take a week.
After six months, Carl knows the company's voice.
Designer
Briefs, moodboards, campaign sites, client decks. Every project room looks different — because every project is different.
Carl learns the studio's taste, project by project.
Accountant
Reports, summaries, deadline reminders. No cloud. No one sees your clients' numbers.
After tax season, Carl remembers every client edge case.
Musician
Uploads a rough demo. Carl finds the harmonic precedents, the artists who worked in this key, this mood, this tempo.
Over time, Carl knows her sound better than she can explain it.
Doctor
Patient notes, research, case histories — all local. Carl cross-references symptoms with literature, surfaces relevant studies, and learns how this doctor thinks. No cloud. No hospital IT risk.
No one reads this but her.
Novelist
Three years of a novel. 400 characters. 12 storylines. Carl holds the entire world — flags contradictions, finds where the timeline breaks.
Carl remembers what the author decided in chapter 4 about a detail in chapter 31.
Researcher
The internet is noise. Carl filters it. Every relevant paper, every contradicting source, every gap in the existing literature — surfaced.
Over time, Carl knows the field as well as she does.
Baker
Menu updates, supplier emails, a website that actually gets updated. Carl handles the parts that aren't baking.
After a season, Carl knows the rhythm of the shop.
The welcome screen

The moment your bicycle takes its shape.

Each Carl begins with a conversation. You take your time, talk, and Carl shapes itself around you — your voice, your work, your pace. It never stops reshaping.

Any mind. Multiplied.

Not just faster at the same tasks. Wider. Carl connects what you know to what has always been known.

This is the bicycle.
Carl — yours to make yours

Any mind.  Multiplied.  This is the bicycle.

The brain

Local when private. Cloud when powerful.

Carl runs Mistral 7B locally — no internet required, nothing leaves the device. Connect any other model you want. The memory stays here. The thinking can come from anywhere.

Carl

Mistral 7B. Runs on the device. Nothing leaves.
Always private

Cloud — Optional
GPT-4o Claude Gemini Custom
Or any model you install.

Your conversations and memory stay on the device — regardless of which brain you use.

The hardware

Built to run AI. Nothing else.

A purpose-built AI computer. Every component chosen to run a full language model locally — silently, efficiently. Plug it in. It works.
