Frequently asked
What file types does Lumina support?
PDFs, Word documents (.docx), and presentation files (.pptx) for uploads. For links, any YouTube video or standard web article URL. Audio uploads support MP3 and WAV files.
How does spaced repetition work?
Lumina uses an SM-2 style algorithm. When you review a card and mark it 'Known,' the system schedules it further in the future. Cards marked 'Review again' come back sooner. Over time, this minimises the reviews you need while maximising retention.
Can I use Lumina offline?
AI processing requires a connection. Once your workspace is built, the summary, cards, and practice sets are cached — so you can study them without a live connection.
Is my uploaded content stored?
Your source material is stored securely, associated with your account only. We do not use your content to train AI models. See our privacy policy for full details.
What's the difference between Quick recap and Deep study?
Quick recap creates a concise summary and a small set of key cards — ready in under a minute. Deep study generates a full structured summary, a complete card deck, a comprehensive practice set, and an audio recap. Takes a little longer, but gives you everything.
