Never Forget What You Learn
Most of what you learn fades within weeks. Refresher turns your books, PDFs, and topics into quizzes that come back on a spaced schedule — so six months later you still know it.
Built to Make What You Learn Stick
Most quiz tools test you once. Refresher keeps the knowledge alive over time.
Spaced Repetition
Questions resurface on an expanding schedule — 1, 3, 7, 21, then 60 days — timed to the moment you would otherwise forget.
Add What You Learn
Search for a book, upload a PDF, or pick a topic you want to keep.
AI-Generated Quizzes
Focused recall questions built from your exact material in seconds.
See What Sticks
Track what is due, what is mastered, and which ideas need another pass.
How It Works
Start in minutes and build daily momentum.
Add Your Content
Search for books, upload a PDF, or start from a curated topic.
Generate Quizzes
AI analyzes your source and creates context-aware multiple-choice questions.
We Schedule the Forgetting
Each question comes back at the right interval — right as you would start to forget — so recall gets stronger every time.
Why It's Different
The point isn't generating a quiz. It's still knowing the material months later.

Frequently Asked Questions
Quick answers before you start.
Most tools quiz you once and stop. Refresher schedules each question to come back at expanding intervals — 1, 3, 7, 21, then 60 days — using spaced repetition, the most validated technique in memory research. That is what turns a one-time quiz into knowledge you actually keep.
