Turning passive notes into interactive mastery.
Fern converts any topic or document into a structured, AI-generated study session, flashcards, quizzes, summaries, and graded problem-solving, then schedules it for long-term retention. We took it from concept to a live product.
Students drown in material and starve for retention. The default study loop, re-reading notes and highlighting, feels productive but barely moves long-term memory. The tools that do work (active recall, spaced repetition, varied task types) are tedious to set up by hand, so almost nobody does.
The brief we set ourselves: collapse the gap between "I have material" and "I'm actively studying it" to near zero, and make the resulting session genuinely adaptive, not a static deck of cards.
From input to a tuned session in seconds.
Six interlocking systems, each pulling its weight against the same goal: a session a student will actually finish and remember.
Dual input pipeline
Type a topic prompt or upload a PDF / DOCX. Content is auto-extracted and understood before a single task is generated.
AI session generator
The model analyzes the material, picks the best task types, and scales the whole plan to the time the student actually has.
Six task types
Flashcards, knowledge checks, quizzes, summaries, mnemonics, and graded problem-solving, routed intelligently per topic.
Focus mode
A distraction-free study surface that walks the student through tasks one at a time with live progress tracking.
AI answer evaluation
Open-ended problem attempts are graded by the model with specific, actionable feedback, not just right/wrong.
Spaced repetition
Due-card scheduling resurfaces material at the right interval so what was learned actually stays learned.
We chose a stack that's modern where it matters and boring everywhere else, fast to ship, cheap to run, and easy for one developer to maintain.
A live product, not a prototype.
Fern shipped and runs in production today. The system holds together because every task type feeds the same retention loop.
