更聪明地学习, 记得更久。

间隔重复算法在科学最优时间点向你展示卡片,帮助你记忆速度比传统学习快 2 倍。多种学习模式 — 书写、多项选择、配对游戏 — 让你保持投入。

Flashcards World 在所有设备上无缝运行 — iPhone、iPad、Android 手机和平板,以及任何网页浏览器。卡片通过我们的安全云自动同步,学习进度随时跟随你。

可以。iOS 和 Android 原生应用让你在没有网络的情况下学习、创建卡片和复习。重新联网后,应用会自动同步进度到所有设备。

是的 — Flashcards World 在网页上完全免费。创建并学习无限卡片、使用间隔重复、浏览 10 万以上现成卡片集、跨设备同步,全部免费,网页无广告。iOS 和 Android 应用提供面向高级用户的可选应用内附加功能。

No — you can create cards and study without an account. Signing in (free) only unlocks cross-device sync and lets you publish public sets.

Your decks are stored locally on each device first and only sync to our servers if you are signed in. We never sell your data, never train AI models on your decks without explicit consent, and you can export or delete everything at any time. See the privacy policy for details.

自适应算法追踪你回忆每张卡片的难易度。难记的卡片更频繁出现,已掌握的卡片间隔更长 — 帮助你构建持久的长期记忆,不在已知内容上浪费时间。

当然可以。上传图片作为视觉提示,附加音频用于发音练习,使用 Markdown 格式让卡片更具表现力。所有媒体在你的设备之间保持同步。

Five modes: classic flip (tap to reveal), multiple choice, writing (type the answer), drawing (sketch the answer — great for kanji, anatomy, formulas), and audio review (eyes-free for commutes and workouts).

Yes — the mobile apps include AI-assisted card generation. Paste a topic, a textbook chapter, or a PDF and the AI drafts flashcards you can then edit. Studying itself is always algorithmic (FSRS), not generative — your reviews are deterministic, not dependent on an LLM.

可以从 CSV 文件、Anki 卡组(.apkg)和 Excel 表格导入。从笔记自动生成卡片,通过 QR 或链接分享卡组,并导出以便随身携带你的卡片库。

Both use spaced repetition (Flashcards World uses FSRS, the modern algorithm; Anki uses SM-2 by default, FSRS as an option). Flashcards World is friendlier out of the box — five built-in study modes (Anki has flip only by default), AI card generation, and a polished mobile experience. Anki is more customizable for power users via add-ons; Flashcards World is closer to a turnkey app.

Flashcards World is offline-first, has actual spaced repetition (FSRS) on free accounts, and is ad-free on the web. Quizlet gates its SRS-style "Learn" mode behind a paid plan and shows ads to free users. Both have large public-deck libraries; ours is searchable without a sign-in.
