Revisely Alternative: More Input Types, Real Spaced Repetition

What Revisely Does Well

Revisely deserves credit for making AI flashcard generation accessible. You paste text or upload a PDF, and it generates flashcards. The interface is clean and the output is usually reasonable. For students who just want a quick set of cards from their notes, it works.

Where It Falls Short

The limitations show up quickly once your study needs go beyond basic text input:

• No YouTube support — if your lectures are recorded, you can't generate cards from the video. You'd have to manually copy the transcript.
• No image input — handwritten notes, textbook photos, and diagrams can't be processed directly.
• No DOCX upload — if your study guide is in Word format, you need to copy-paste the text first.
• No spaced repetition — Revisely generates cards but doesn't offer scheduled review. You study everything equally, with no algorithm tracking what you know vs. what you don't.
• No Anki export — if you want to move your cards to Anki for long-term study, there's no .apkg export option.
• No image occlusion — for anatomy, diagrams, or any visual material, you can't create occlusion-style cards.

These aren't edge cases. YouTube lectures, image-based notes, spaced repetition, and Anki export are core parts of how serious students study.

What Deckio Adds

Deckio covers the same base — AI flashcard generation from text and PDFs — and then goes further:

More Input Types

Upload PDFs (up to 500 pages on Ultimate), paste notes, upload DOCX files, take photos of handwritten notes with OCR, or paste a YouTube lecture URL. The AI processes whatever format your study material is in.

More Card Types

Standard Q&A, cloze deletion (fill-in-the-blank), multiple choice with distractors, and image occlusion. You choose the type before generating, or let the AI pick the best format for the material.

Spaced Repetition That Actually Works

Deckio uses the SM-2 algorithm — the same one behind Anki. After reviewing each card, you rate your recall (Again, Hard, Good, Easy), and the algorithm schedules your next review at the optimal interval. This is what turns flashcard generation from a one-time exercise into an actual study system.

Anki Export

Export any deck as a .apkg file and import it directly into Anki. Generate cards quickly in Deckio, then study them in whatever tool you prefer long-term.

Side-by-Side Comparison

Who Should Switch

If Revisely covers everything you need — quick text-to-flashcard generation for occasional use — there's no reason to switch. It does that job fine.

But if you're studying from YouTube lectures, need spaced repetition to actually retain what you generate, want to export to Anki, or work with images and diagrams, Deckio gives you a more complete study workflow. Generation is the starting point — what happens after is what determines whether you remember the material a month later.
