A learning engine — not a learning app
A personal knowledge graph that proves retention over time: spaced repetition, active recall, and AI grading.
Added to your graph, not yet studied.
Due for review. The node pulses as memory decays.
Recalled correctly. Retained and durable.
Overdue and slipping. Time to relearn.
Everything on top of the graph
Paste text, drop a URL, or upload a file. An AI pipeline extracts the concepts, links them, and seeds flashcards for every node — you start studying, not organizing.
Open the Tutor on any node to explain, connect, or drill deeper. Every answer cites your own sources and can mint a flashcard on the spot — you confirm, it lands on the node.
Once a concept is mastered it unlocks a three-step ladder: replicate, duplicate, iterate. Free-text answers, graded with feedback — no multiple choice, no shortcuts.
Invite people as Viewer, Learner, or Editor. Learners get their own progress and flashcard state; editors can extend the graph. Revoke or rotate access anytime.
Flip a graph to Unlisted for a private link, or Public to make it discoverable. Anonymous visitors can read, and any signed-in learner can copy it to their account with one click.
Browse a gallery of public graphs from other learners. Fork one you like, then let the engine track your own retention on top of it.
Why it works
The graph is the proof. Green nodes are recalled, amber is fading, red has lapsed — no dashboards, no vanity streaks.
Spaced repetition surfaces the concept you're about to forget, on the day you're about to forget it. Reviews take minutes, not hours.
Share a graph as a Learner and your progress is yours. Same concepts, separate mastery — study a colleague's graph without polluting theirs.
Weeks later the graph still tells the truth: which concepts stuck, which decayed, which you never actually held. Evidence, not assertions.
