FlashKeepers is an independent product, not affiliated with or endorsed by Mindflow Inc. Jungle (formerly Wisdolia) turns uploaded slides, PDFs, links and YouTube videos into AI multiple choice questions, but the free tier is capped at 3 generations a month and asks you to sign up before you see an answer. FlashKeepers gives you 6,119 ready-made decks, no account needed for the free web app, and AI cards checked against the source, free, one-time $14.99 Pro. FlashKeepers also has a free iPhone and iPad app on the App Store, and Android as a direct download.
"Jungle" is a trademark of Mindflow Inc. Pricing and feature figures are from Jungle's public pricing page at jungleai.com as of September 2026 and may have changed since.

If you've been generating Jungle sets from your own PDFs, slides, or lecture videos, the migration is mostly about the source material, not the sets themselves: there's no direct Jungle-format import today, but since Jungle sets are AI-generated from source documents in the first place, regenerating the same material through FlashKeepers' own link/PDF/PowerPoint/YouTube pipeline is usually just as fast as re-uploading, and avoids Jungle's 30-page and 30-minute caps if your source material is long. One thing to know going in: Jungle's paid tier adds "AI explanations" and chat-with-your-document features that FlashKeepers doesn't have an equivalent for. If that conversational layer on your material specifically is what you relied on Jungle for, FlashKeepers' AI-generation model (cards checked against a quoted source span, then a straightforward review loop) is a narrower tool by design, not a superset.
No. FlashKeepers is an independent app and is not affiliated with, endorsed by, or sponsored by Mindflow Inc. It supports the same kind of upload-and-study flashcard review Jungle users already rely on.
Yes, FlashKeepers' web app lets you paste a link or drop a PDF, Word, or PowerPoint file and generate cards with no account required, unlike Jungle, which requires logging in even on its free tier before showing you a generated answer.
If your document is under 30 pages, both work about the same on their free tiers. Past 30 pages, Jungle's free plan caps out and pushes you toward its paid Super Learner tier; FlashKeepers doesn't apply a page cap on the free generation allotment (though the free tier does cap total AI generations at 10 before Pro or a credit pack). For a genuinely long source document, FlashKeepers' free tier is less likely to hit a wall mid-document.
No. Jungle's entire model is generating sets from material you provide; it has no ready-made catalog. FlashKeepers has both: 6,119 ready-made decks across 358 subjects you can study immediately, plus the same kind of generate-from-your-own-material pipeline Jungle offers.
It's usable but tightly bounded: 3 generations a month, a 30-page document limit, a 30-minute video limit, and a handful of advanced/diagram questions. For occasional single-use generation it's fine; for regular use, most people end up choosing between Jungle's paid Super Learner subscription and a less capped alternative.
Teach-back is FlashKeepers' spoken-recall check: you say your answer out loud, on-device speech recognition transcribes it, and AI grades whether you actually got it right, with a one-line explanation of the gap. Jungle doesn't have an equivalent; its review loop is closer to a generated quiz (multiple choice, diagram, and "advanced" question types) than a spoken-recall system.
For frequent generation, yes in most cases: FlashKeepers' $14.99 is a one-time unlock plus optional small credit-pack top-ups, while Jungle's uncapped generation requires the recurring Super Learner subscription. If you only generate occasionally and stay under Jungle's free caps (3 generations a month, 30 pages, 30-minute video length), Jungle's free tier can also be enough, it depends on your actual volume.
