Inside a Barn
A Barn is where a concept comes alive.
Click a node on your map and you don’t get a wiki entry. You step into a Barn — one concept, rendered as an immersive page that reads more like a short documentary than an article.
A Barn moves with you. Narration in part text, part voiceover. Diagrams that animate as the story unfolds. 3D models you can rotate. Lab footage from the original experiment. Pause-able simulations where you change a variable and watch the equation bend. The format follows the concept — topology gets a mesh, music theory gets sound, code gets code you can read.
No two Barns feel the same. But every one ends the same way: with a question only you can answer.

How it works
Three steps. No setup.
Tell Arnapse what you want to understand.
A topic, a question, a paper — anything you're curious about.
Watch your mind map grow.
Arnapse builds barns from primary sources, one connected idea at a time.
Explore at your own pace.
No streaks, no metrics. Your map is yours forever.
Features
A different way to learn,
built on how the brain works.
Four things Arnapse does differently — each grounded in research, not in engagement metrics.
01 · Living mind map
Your understanding, made visible.
Every topic you explore expands a personal map of connected ideas. Watch your knowledge grow node by node — your map is the only progress indicator you need.
02 · Source Zero
Every fact traces to the original.
No telephone game. Each claim is grounded in the original paper, experiment, or proof — and you can open the source in one click.
Plants convert light into chemical energy through photophosphorylation — a process discovered by Daniel Arnon in 1954.
03 · Side quests
Follow a curiosity without losing your place.
Mid-barn, tap any branching idea to spin off a side quest. Explore it fully — when you're done, the main thread is right where you left it.
04 · No streaks, no points
Learn for understanding, not metrics.
No daily-streak guilt. No XP bars. No leaderboards. The expanding map is the only metric — and it belongs to you.
A note from the founder
Most learning apps optimize for time-on-app. Arnapse optimizes for understanding — the kind that stays with you years later, that connects to everything you learn next, that you can use to think for yourself.
Learn it. Love it. Live it.

Research
Built on published research.
Arnapse isn’t an opinion. Every piece of the engine traces back to peer-reviewed work on memory, learning, and skill formation.
FSRS-6 - Personal forgetting curves
Open Spaced Repetition
Drives review timing for every concept; learns each user's personal forgetting curve after ~100 reviews.
Read the paperMemory: A Contribution to Experimental Psychology
Hermann Ebbinghaus
The public-domain source behind the forgetting curve.
Read the paperTest-enhanced learning: Taking memory tests improves long-term retention
Roediger & Karpicke
Active retrieval beats re-reading; every barn ends with a generation challenge, not a summary.
Read the paperMaking things hard on yourself, but in a good way: Creating desirable difficulties to enhance learning
Elizabeth L. Bjork & Robert A. Bjork
Open-access chapter on spacing, interleaving, and testing as desirable difficulties.
Read the paperSpacing effects in learning: A temporal ridgeline of optimal retention
Cepeda et al.
Distributed practice outperforms massed practice; FSRS-6 enacts this concept-by-concept inside the user's barn.
Read the paperThe Effect of Interleaving Practice
Kelli Taylor & Doug Rohrer
Mixing related concepts improves discrimination and transfer; we interleave concepts within a topic, not block them.
Read the paperThe generation effect: Delineation of a phenomenon
Slamecka & Graf
Information you produce is remembered better than information you read; every checkpoint is generation, not recognition.
Read the paperReconsolidation of long-term memories
Nader, Schafe & LeDoux
Retrieving a memory makes it temporarily editable; we time concept revisits to ride the reconsolidation window.
Read the paperThe magical number 4 in short-term memory: A reconsideration of mental storage capacity
Nelson Cowan
We cap the number of new concepts shown per section to ~4 to respect working-memory capacity.

We're aiming for a private beta with the early-access list later this year, then a broader launch in 2026. Joining the list is the only way to be first.
Anything you're genuinely curious about — from photosynthesis to monetary policy to how transformers work. Arnapse is designed for ideas you want to actually understand, not pre-canned curricula. If you can phrase it as a question, you can build a Barn from it.
Our goal is to cover the most popular topics first, but we won't be able to cover everything from the start, we will gradually roll out the new feilds and topics starting from computer science.
Every claim in Arnapse traces back to the original paper, experiment, or proof — not to a blog post that summarized a paper that summarized a paper. You can open the source in one click.
