What it does
Talk to your knowledge.
Your tutor reads from the same concept graph you’re building. Ask a question and it answers from your own sources — with citations you can tap into.

Why do mitochondria have their own DNA? I keep mixing this up with the nucleus.
Tutor
The endosymbiotic theory: mitochondria descend from free-living bacteria that one of your ancestor cells swallowed roughly 1.5 billion years ago. They kept their own DNA loop because they were a separate organism before they were an organelle.
You confused this with the nucleus on May 3. The nucleus is the cell’s library; the mitochondria are long-domesticated guests that brought a phrasebook of their own.

How it works
Built on the science.
Forty years of cognitive-science research. A tutor that remembers you across months. None of this is decorative.
Session arc
From recall to teach-it-back.
Every session climbs from quick recall up through explanation. The shape stays; the cards change.

Concept graph
What you’ve learned, mapped.
Cards link into concepts. Concepts link into prerequisites. The next thing to learn is the next one ready.
Concept mastery — your living knowledge map
Knowledge that grows with you.
One notebook. Whatever you’re trying to learn. For as long as you stay curious.
