Stop rereading.
Start remembering.
Drop in a PDF, a Word doc, a screenshot or a wall of notes. Recallo chops it into one-idea cards, asks you the questions, and brings each one back right before you'd forget it.

How it works
Your brain isn't bad at remembering. It's bad at swallowing chapters whole.
Chunk it
Paste or upload anything. AI splits it into cards of exactly one idea — a sentence, about thirty seconds out loud.
Retrieve it
See the question, answer from memory (out loud or typed), flip, then grade yourself: easy, medium or hard.
Space it
The SM-2 scheduler brings hard cards back tomorrow and stretches easy ones out to weeks. Only today's few are due.
The forgetting curve
Memory is wired by effort, not exposure.
Every time you pull an answer out of your head just as it's fading, the memory gets stronger and fades slower. Recallo times each review to hit that sweet spot — so 15 minutes a day beats an all-nighter.
Upload anything
PDF, Word (.docx), PNG/JPG screenshots, or just paste text.
Hear every card
Generate a natural voice for questions and answers. Study on a walk.
One idea per card
Short prompts that force retrieval — never a paragraph to reread.
Streaks that stick
A small daily dose and a flame to protect. Habit, not chore.
