You forget what you learn.
Aristotle doesn't.

Aristotle reads your course materials, builds your concept map, and generates study tools automatically — flashcards, practice questions, concept briefings. Seven ways to study. Nothing ever resets.

See how it works

A bicycle for your mind — and the first teacher that never forgets what you've learned.

What it actually looks like

Three views.
One learning system.

Tap through to see how Aristotle works.

I built Aristotle because I ran out of options.

Two weeks before my exam block I still hadn't organized my materials. Five courses, dozens of PDFs, no idea what I actually understood versus what I'd just read past. Three days before exams I sat down to build a plan. It took three full days just to figure out where I stood.

I passed. But it had collapsed like a house of cards. Next semester: same stack of PDFs. Same starting from zero.

In March I started building something for myself. By the time it worked, my entire relationship with studying had changed. I realized it couldn't be just for me.

The system was never designed for this

Five courses.
Twelve weeks.
One semester. Gone.

01

PDFs in three apps, no structure. You spend the session organizing instead of learning.

02

You've read everything. You've highlighted. Familiarity is not knowledge — the exam is where you find out.

03

Five courses at once. You prioritize by deadline, not by understanding. You find out which course needed you most too late.

04

You pass. Within weeks, 90% is gone. Next semester: same PDFs. Same starting from zero.

The semester was designed to reset.
Aristotle was designed not to.

What Aristotle does

Seven ways to learn.
One that fits right now.

Drop in your courses. Aristotle reads everything, maps every concept, and generates your study tools. Then you choose how to work today.

Reads everything

PDFs, slides, past exams — any format. Aristotle maps every concept and how they connect.

Generates study tools

Flashcards, practice questions, briefings — built automatically from your actual materials.

Seven learning modes

Quiz, Briefing, Feynman, Socratic, Speed Round, Boss Battle, Pomodoro. You pick what fits today.

Tracks what you know

Weak spots surface before the exam, not during it. The longer you use it, the better it knows you.

Most tools help you study more.
Aristotle makes sure what you study actually stays.

The collective

Someone already mapped
your course.

When a student configures Aristotle for a course, they can share that structure publicly — by subject and university. Their architecture, your materials.

Find a Space

A student mapped your course — every concept, every dependency, the order that makes it click. You see their entire learning architecture: concept map, roadmap, mode setup.

Make it yours

Their materials stay theirs. You upload your own. Aristotle applies their structure to your documents. You start from the best version your class has built.

Build together

The more students refine a Space for the same course — the better it gets. Not shared notes. A shared understanding of a subject.

Picture every course at every university mapped by the students who've already taken it — the concepts, the dependencies, the order. Built collectively, owned individually. That's what Spaces becomes.

Early access

Join early. Help build it.

Aristotle is in active development. Early users shape what it becomes — which modes we build next, how the interface evolves, how Spaces grows at scale. The students who join now aren't users. They're co-builders.

In return: yours for life.

The system was never designed for this

You organize. You memorize.
You pass. You forget. You start over.

01
Get organized (somehow)
You open your laptop to study. The scope of it stops you — PDFs in three places, no structure, no path. You spend the session organizing instead of learning.
→
02
Memorize for the exam
You read everything. You highlight. You feel like you know it. Familiarity is not knowledge — and the exam is where you find out the difference.
→
03
Ask an AI
It doesn't know your exam is next week. It doesn't know what you already understand. It doesn't remember your last session. Every conversation starts from zero.

04
Bicycle-Aristotle
Reads your materials. Generates your flashcards and practice questions. Tracks what you actually know, concept by concept. Remembers everything from the last session. Nothing resets.

The problem was never that students don't work hard enough.
It's that no tool ever remembered what they learned.

The idea

"We are what we repeatedly do. Excellence, then, is not an act but a habit."

Aristotle, Nicomachean Ethics · The idea behind the name.

The student who reads the same slide five times feels like they know it. They don't. Knowledge is not familiarity — it is what you can recall, apply, and connect under pressure. Bicycle-Aristotle doesn't help you re-read. It builds the habits that turn material into mastery.

What it does

Not a study app.
Your individual learning companion.

Aristotle reads your materials, maps every concept, and generates your study tools automatically — you don't build Anki cards or Quizlet decks. He works directly in your folders, tracks your knowledge concept by concept, and gets better the longer you use him.

01

Reads your materials

PDFs, lecture slides, past exams — any subject, any format. Aristotle processes the structure, extracts every concept you need to learn, and maps how they connect. Not just text. Understanding.

02

Generates your study tools

Flashcards, practice questions, concept briefings, daily reviews — all built automatically from your actual course materials. No manual setup. You upload your courses. He does the rest.

03

Tracks what you actually know

Every session updates your knowledge per concept. Aristotle always knows what you've mastered, what's slipping, and what you've been avoiding. The forgetting curve works against you. Aristotle works against it.

04

Works in your folders

Aristotle can create files, write summaries, and organize your materials the same way you would — directly in your course folder. His notes are plain markdown. Open them anywhere. They're yours.

05

Shapes itself around you

The interface isn't a template. Onboarding is a conversation — Aristotle asks how you study, then builds a layout that fits. Seven learning modes. You choose the one that fits today. Two students using Aristotle shouldn't feel like they're using the same app.

Most tools help you study more. Aristotle makes sure what you study actually stays.

Seven learning modes

Seven ways to learn.
One that fits right now.

Quiz and passive reading activate different parts of understanding. Aristotle gives you seven distinct ways to engage with your material — depending on where you are in the learning cycle, how much time you have, and what the exam demands.

v1
Flash Sprint
Active recall against the forgetting curve. Aristotle generates questions from your materials and schedules reviews using FSRS — the most accurate spaced repetition algorithm. Every card flip updates your concept confidence.
Active recall · FSRS algorithm
v1
Briefing
Aristotle walks you through a topic from your materials — structured, grounded, conversational. Surfaces which concepts you know, which are weak, and which you haven't touched. Best for first exposure or pre-exam review.
Structured review · RAG-grounded
v1
Feynman
Explain a concept in plain language, as if teaching a 16-year-old. Aristotle reads your explanation against your course materials and identifies exactly where understanding breaks down. No vague feedback — only specific gaps.
Feynman Technique · Gap analysis
v1
Socratic
Aristotle only asks questions. Never gives answers. You reason your way to understanding through dialogue. The most demanding mode — and the one that builds the deepest retention.
Socratic dialogue · No answers given
v1.5
Speed Round
Twenty of your weakest concepts, rapid-fire. Three minutes. Three buttons: Wrong / Almost / Got it. No review step — just quick-fire calibration of what you know right now.
Interleaving · High-difficulty weighting
v1.5
Boss Battle
Weighted questions from all chapters at once. Never two consecutive cards from the same topic. Ends with a synthesis question connecting three or more concepts. The pre-exam mode.
Interleaved practice · Synthesis questions
v1.5
Pomodoro Focus Room
Structured 25-minute block: Briefing → Quiz → Feynman attempt → Break. Aristotle guides the transitions and ties everything to your current roadmap topic. For when you need to actually sit down and work.
Time-blocked deep work · Multi-mode
The founder

I built Aristotle because I ran out of options.

Two weeks before my exam block, I still hadn't organized my materials. Not because I didn't want to — every time I opened my laptop to start, the scope of it stopped me. Five courses, dozens of PDFs, notes in three different places, no idea what I actually understood versus what I'd just read past.

I kept putting it off. I'll sort it this weekend. Then the next weekend. Then there was no weekend left.

Three days before exams started, I sat down and tried to build a plan — what to study, in what order, how much time each course needed, where the biggest gaps were. It took three full days just to figure out where I stood. Three days I didn't have.

I passed. But the whole thing had collapsed like a house of cards. All that time, all that reading — and I walked out of exams not knowing what I actually retained. Next semester: same stack of PDFs. Same starting from zero.

In March I started building something for myself. Something that would read my materials so I didn't have to sort through them. Something that tracked what I actually knew, not what I'd highlighted. Something that turned my PDFs into study tools automatically — flashcards, concept maps, practice questions — without me having to build any of it.

I kept updating it. Fixed what didn't work. Added what I actually needed. By the time it was stable, my entire relationship with studying had changed. I wasn't spending time organizing anymore. I knew exactly where my gaps were. I was retaining things across courses, connecting concepts I'd studied months apart.

I realized it couldn't be just for me.

The social layer

Someone already mapped
the roadmap for your course.

When a student tunes Aristotle to a specific course — structures the concepts, builds the learning path, figures out the right order — that work doesn't have to stay private. They can share it. A link to a classmate, or publicly by subject and university.

01
Find a Space
Another student configured Aristotle for the same course — every concept, every dependency, the learning order. They made it public. You open it and see their entire learning architecture: the concept map, the roadmap, the mode setup for each topic.
02
Make it yours
Their materials stay theirs. You upload your own. Aristotle applies their learning architecture to your documents. Their structure, your knowledge, your sessions. You don't start from scratch. You start from the best version your class has built.
03
Build together
The more students refine a Space for the same course, the same professor, the same exam — the better it gets. Not shared notes. A shared understanding of a subject. Every university course can have one.

Picture every course at every university mapped by the students who've already taken it. Not notes — the architecture of understanding: the concepts, the dependencies, the order. Built collectively, owned individually.

That's what Spaces becomes when students share them.

"Spaces are opt-in. Private by default. You share when you choose to."
"Launching in v1 — search by subject, university, or share link."
The interface

And this is what it actually looks like.

Three views you'll live in every day. The Home Space — every course on one pinboard, Aristotle's daily brief, your streak. The Room — Aristotle's monologue about where you are, The Map of what's left to learn, four ways to start. And Focus Mode — fullscreen, no distractions, just the question in front of you. Click the room cards to navigate — just like in the real app.

The hardware arrives
bicycle.ai runs on a device built for it. Not a computer running AI software. An AI device, from the ground up.

Bicycle-Aristotle is a product. But it is also a proof — that an AI can learn who you are, remember what you've learned, and make you genuinely better at thinking through hard material.

Once that's proven for students, it works for everyone.

That is what bicycle.ai is building. Aristotle is where it starts.
