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 1,324 ready-made decks, no account needed for the free web app, and AI cards checked against the source, free, one-time $7.99 Pro.
"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.
The parts of daily flashcard review that actually decide whether you keep using the app.

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.
Both, on FlashKeepers. Pick any of the 1,324 ready-made decks and study it as-is, or paste a link, drop a PDF, slides or a YouTube video and generate your own. Jungle has no ready-made library, every set starts from your own material.
Not on FlashKeepers. The free web app works with no account and no sign-up. Jungle requires sign-up before it shows you an answer.
Instead of just flipping the card and rating yourself, you speak your answer out loud. On-device speech recognition transcribes it, and an AI grades whether you actually got it right, with a one-line explanation of what you missed and a suggested spaced-repetition rating.
No. It's a single one-time unlock, $7.99, yours for good, no monthly or annual renewal.
No, never, on the free tier or Pro.
