Notebooks written in Sumi are already here.
After the ink settles
Not six generators that happen to share a login. The same source stays attached to everything it becomes. Open any tab and check.
Photosynthesis study kit
Built from one lecture
Structured · Notes
Biology / Lecture 04 / Photosynthesis
Light-dependent reactions convert light into ATP and NADPH. Sumi keeps the core idea, its source, and its connected concepts together.

Flashcards
Sumi pulls the testable facts out of your own material, then brings each card back exactly when you're about to forget it.
Quizzes & Exams
A quick check between classes or a full timed exam before the real one. Questions target what you don't know yet, and every answer traces back to your source.

This week
Built from your exam dateLighter days early, heavier review as the exam nears.
Planner
Tell Sumi when the exam is. It spreads the work across the days you have, and rearranges when life gets in the way.
Connected understanding
Notes stop living in separate stacks. Every idea, question, and connection stays tied to the source it came from.
Knowledge Atlas
A mind map covers one topic. The Atlas is every course you have finished — still connected, still reviewable. Move the semester forward and watch it fill in.
Atlas began with bio-lecture-04-photosynthesis.pdf
Week one
One lecture becomes a place.
Concepts, evidence, questions, and the first review plan stay connected to their source.
Nothing here was filed by hand. Every concept, source, question, and review slot arrived with the lecture it came from.
Summit · practice
Studying tells you what feels familiar. Summit tells you what you can actually retrieve, because you commit to an answer and to how sure you were, before it grades you.
Daily Challenge
A short mixed set every day, drawn from the courses you are actually behind on.
Gauntlet
One long run across every class at once. The closest thing to an exam before the exam.
Personal climb
Camps and elevation that only move when recall holds days later, not when you cram.
Why the confidence step matters
Answering right while feeling unsure, and answering wrong while feeling certain, are different problems. Summit separates them, so your weak spots are the ones you actually have, not the ones you assume.
Every result flows back into review scheduling and the Atlas.
Try the climb. The questions are samples, but the loop is the real one.
Try a climb
Base camp · 0 of 4
A correct answer moves you up. A miss costs one ledge — never the whole climb.
Question 1
Sample · Cell biology
Which organelle produces most of a cell's ATP?
Choose an answer. The mountain will respond.
Base Camp → Ridgeline → Summit
Elevation only moves when recall holds days later.
Evidence
Built on retrieval practice and spaced repetition, the most effective ways to build long-term memory.
Retrieval practice works
Recall one week later — re-reading vs. testing yourself (Roediger & Karpicke, 2006).
Spaced repetition sticks
Review just before you forget for maximum retention (Cepeda et al., 2006).
Your progress, clearly
Watch understanding grow across topics over time.
Privacy
We never sell your data. Your notes and progress are private, secure, and always under your control, and you can export everything, free, forever.
Less setup. More understanding.
