Both get recommended as "the" serious spaced-repetition app, but they schedule your reviews in genuinely opposite ways, not a simple better-or-worse split. Anki tells you exactly when to see a card again. Brainscape just tells it to come back sooner or later than the others, based on how confident you said you were. Here's what actually differs — cost, scheduling logic, and which one fits which kind of studying.

Anki's scheduler is derived from the SM-2 spaced-repetition algorithm and works in absolute terms — it assigns each card a specific interval, like "you must study this card again in 4 days," based on how you rated your recall. As of version 23.10 (October 2023), Anki also added FSRS (Free Spaced Repetition Scheduler) as an optional, newer algorithm alongside the classic one, for anyone who wants a more modern model without switching apps.
Brainscape calls its own approach "relative" rather than absolute. You rate each card on a 1-to-5 confidence scale after seeing it, and a card you rated 4 simply comes back later than the 1s, 2s, and 3s already in rotation — there's no fixed "see this again in exactly N days" promise the way Anki gives one. Brainscape's own comparison page claims most of its users prefer this relative method, though that's a vendor claim without published data behind it, not an independent finding.
Anki is free and open source on desktop (Windows, Mac, Linux) and on Android via AnkiDroid; the one paid piece is AnkiMobile on iOS, sold as a one-time purchase (reported around $25, though pricing can change — check Anki's own site for the current figure) rather than a subscription. Brainscape is free to create and study an unlimited number of your own cards, with a Pro subscription layered on top for certified, expert-made decks and some premium features.
On G2, both tools carry the same 4.6-out-of-5 overall rating, but the sample sizes aren't close — 34 reviews for Anki versus 350 for Brainscape — so treat any head-to-head score gap as a weak signal. Within that caveat, Brainscape scores noticeably higher on ease of use and ease of setup, while Anki scores a bit higher on support and "meets requirements." That roughly matches the general reputation each tool has: Anki rewards the time you put into learning its interface and settings; Brainscape is built to feel usable without reading a manual first.
Neither Anki nor a plain Brainscape deck builds itself by default — you're typing cards in or importing a set either way, though Brainscape's own comparison page does mention an AI toolkit that can generate cards from notes "within minutes" as part of its broader platform. StudyPilot's flashcard tool does that same job as its default starting point rather than an add-on: paste in your notes, slides, or a PDF, and it generates a full card set automatically, with spaced repetition built in, free for up to 2 sets a week, no install and no account required to try it.
It isn't trying to match Anki's deep scheduling customization or Brainscape's certified-content library for long-term, high-volume studying. It's built for the far more common situation — you have a stack of lecture notes and an exam coming up, and the slow part isn't reviewing cards, it's making them in the first place.
Paste your notes or upload a PDF and get a spaced-repetition flashcard deck in under a minute — free for up to 2 sets a week, no app to install.
