What makes a good source?
Clear, text-rich material makes better flashcards. Here's what to reach for — and what to fix before you upload.
The principle
MemoForge builds cards from what it can actually read. The clearer your material, the more accurate the concepts it extracts. Think of it like handing your notes to a careful study partner — they'll do their best with whatever you give them, but legible, organized material gets better results.
A useful rule of thumb: if you could hand the material to a classmate and expect them to study from it, MemoForge can build cards from it too. If you'd apologize for the photo first, fix it before uploading.
Good sources
- Readable scans. A PDF of lecture slides or a course handout with clean, legible text.
- Slides with one concept per slide. Each slide covers a single idea, so each card has a clear anchor.
- Structured notes. Outlines, definition lists, and notes with headings give the AI natural stopping points.
- Captions and transcripts. Videos with subtitles, and articles with real text rather than images.
Weak sources
- Blurry photos. Out-of-focus shots of a page where the text is hard to read even for you.
- Cropped pages. Photos that cut off words at the edges or include a desk, a finger, or shadows across the text.
- Handwriting-heavy images. Dense handwritten notes work sometimes, but loose handwriting is often misread.
- Decorative-only slides. Slides made of images and diagrams with little or no text leave the AI nothing to extract.
- Videos without captions. No transcript, no usable cards — see Deck from URL.
A quick before and after
Works well
A straight-on screenshot of one textbook page, in good light, text filling most of the frame. A slide deck where each slide states one concept in a sentence or two. Notes with headings and a definition list.
Needs work
A photo taken at an angle across a desk, with a thumb over the corner and glare on the page. A slide that is one big diagram with no text. A lecture recording without subtitles.
The difference matters: MemoForge builds cards from what it can read, so the same chapter photographed well or poorly can produce very different decks.
A note on privacy
Only upload material you're allowed to use — your own notes, licensed course materials, or public sources. If a document isn't yours to share, keep it out of any tool that processes it.
Fixing a weak source
- Crop and retake. Re-photograph a page straight-on in good light, or screenshot the cleanest version instead of photographing a screen.
- Split long pages. If one photo has too much going on, split it into a few focused images.
- Add a short context note. A line like “Chapter 3: cellular respiration” helps the AI keep cards anchored to the right topic.
A realistic fix: you photographed three pages of your textbook on your phone and the top of each page is curved and shadowed. Re-shoot them flat on a table in daylight, one page per photo, and crop each to the page edges. That single pass — a few minutes of work — makes the difference between a deck you can trust and one you'll spend the same time correcting.
After generation
Review the generated cards before studying. Edit anything that's wrong or oddly worded, and discard cards that don't matter to you. The AI aims for accuracy, but the final say is yours — a quick review pass is what keeps your deck clean.
