Turn your notes into a
passing exam score.
SRO converts lecture PDFs and notes into AI-generated flashcards, schedules them with neural FSRS-5, and shows your exact predicted retention on exam day — so you always know you're on track.
Projected Exam Day Retention
On track for high mastery threshold
Your brain is wired to forget. SRO rewires it.
Without timed reinforcement, you lose 70% of new information within 24 hours. By test day, cramming yields anxious guessing.
SRO calculates the exact second a memory trace starts to decay, presenting your card for review right at the moment of highest cognitive leverage.
From lecture to long-term memory in three steps.
No manual card crafting. No scheduling math. Just study — SRO handles the science.
Drop in your materials
Upload lecture PDFs, paste notes, or import your entire Anki library in 60 seconds. GhostAI extracts atomic, high-yield flashcards automatically.
Recall, don't re-read
Each morning you get one focused queue of active-recall prompts — flashcards, cloze deletions, image occlusions, and mock questions. Neural FSRS-5 serves each one at the exact moment before you would forget it.
Watch readiness climb
Set your exam date and target score. SRO paces your workload and projects your exact retention on test day, so you walk in knowing you'll pass.
From Deep Reading to Long-Term Retention.
Clean Markdown notes seamlessly connected to FSRS spaced repetition. No clunky outliners, no context lost.
Highlight to Flashcards in 1 Click
5-color highlighter across notes, PDFs, and web tabs that turns key takeaways into instant cloze or AI drill cards.
Teleport to Context
When you struggle with a card during study, one click teleports you directly to the highlighted paragraph in your original note.
