- Activity heatmap showing your study streak across the year
- Personal milestones and badges for study habits and consistency
- Deck milestones tracking maturity progress per deck
- Shared decks tab — a one-stop shop for everything you have published for your peer group or students to bookmark
- Custom bio to introduce yourself to visitors
Scholar+ feature
Your most sensitive knowledge, locked tight
Some of the most important things to remember are also the most sensitive. Social security numbers, account passwords, passkeys, credit card details, emergency PINs — these are exactly the kind of high-stakes facts that benefit most from spaced repetition, yet they're the last things you'd want exposed in a plain-text deck. Encrypted decks let you study them without compromise.
- Deck contents are encrypted with a passphrase only you know — Flipnem never sees it
- PBKDF2-derived keys make each brute-force guess computationally expensive, so a strong passphrase is effectively uncrackable with today's hardware
- Cards stay fully encrypted at rest; they're decrypted in your browser only after you unlock
- Encryption status is visible in your deck library so you always know what's protected
Set a passphrase
When creating or editing a deck, enable encryption and choose a passphrase. It never leaves your device.
Study like normal
Cards are decrypted in-browser on the fly — the study experience is identical to any other deck.
Rest easy
Even if your account were ever compromised, encrypted deck contents are unreadable without the passphrase. Your sensitive material stays yours.
Available on all plans
Cards that render rich content
Flipnem automatically renders code, diagrams, music, and tables inside any card. Write the markup in a card field and it comes to life when you study.
Code blocks
Wrap code in a fenced block with a language tag — ```python, ```rust, ```sql, and dozens more — for instant syntax highlighting.
Mermaid diagrams
Use ```mermaid to embed flowcharts, sequence diagrams, ER diagrams, and more. Ideal for system design, architecture, and process cards.
ABC music notation
Use ```abc to render sheet music directly on your cards. Perfect for music theory, ear training, or memorizing melodies.
Markdown tables
Standard pipe tables render as clean HTML tables. Great for comparison cards, conjugation tables, and reference material.
MathJax (LaTeX)
Inline math with \( ... \) and display math with \[ ... \]. Anki decks with <anki-mathjax> tags render correctly too.
Deck creation
Build decks your way
From hand-crafted cards to AI-managed decks built and reviewed with any MCP-compatible AI
Basic & Cloze cards
Create standard question-and-answer cards or cloze deletion cards directly in the editor. Cloze cards let you blank out key terms inside a sentence — ideal for vocabulary, definitions, and memorizing facts in context. Images are supported on both card types.
Hashcard Markdown importScholar+
Write decks as plain text using a simple Markdown-like format, then import the file. Perfect for generating large decks quickly. Great for textbook chapters, lecture notes, or anything you already have in a document.
View the format on GitHub ↗Edit cards on the fly
Notice something off on a card? A couple of clicks lets you inspect and edit it, make your tweaks, and hop right back into your session where you left off.
AI Managed DecksScholar+
Enable agent control on a deck and connect any MCP-compatible AI assistant via the Flipnem MCP server. The AI can read your source material, build sub-decks, populate cards to your preferences, and run interactive review sessions — all without leaving your chat.
MCP Server
Let an AI be your study partner
Connect any MCP-compatible AI assistant to your Flipnem account. The AI can read your decks, build sub-decks from source material, and run your due cards as an interactive flashcard quizmaster — ratings go straight back into the FSRS scheduler.
Share your mnemonic devices with the AI and it stores them in the deck's memory, surfacing them as hints whenever you need them.
Source Notes
Keep your reference material with the deck
Attach a poem, passage, chapter, or any text to a deck as a Source Note. It is never scheduled for review — it lives alongside the deck as reference material you can read any time from the deck details page.
When an AI connects via MCP, it reads the Source Note automatically — so the AI always has the exact text you want to learn from, without you pasting it into every conversation.

Frequently asked questions
What is spaced repetition?
Spaced repetition is a learning technique that shows you flashcards at increasing intervals based on how well you know them. Cards you struggle with appear more often, while well-known cards are spaced further apart. This is scientifically proven to maximize long-term retention.
Can I use my existing Anki decks?
Yes — import your .apkg directly in the browser, no Anki Desktop required. Cards, notes, images, and audio all come with it. The only things that do not transfer are Anki plugin data, custom note type templates that use JavaScript, and Image Occlusion cards.
What happens if I cancel my subscription?
If you cancel you will revert to the Learner plan. Your decks will remain intact for 30 days, after which your library will be trimmed to the 3 most recently studied decks.
Is my data safe?
Each user gets their own isolated storage. We never share your data. You can export your complete collection at any time in standard Anki format.
Does Flipnem support all Anki files?
Flipnem supports standard .apkg files including basic and cloze cards with images and audio. Most publicly shared decks and self-created decks import without issues. You can also import plain-text decks using .md or .txt files in the Hashcard Markdown format, as well as tab-separated .tsv and comma-separated .csv files for simple front/back card sets.
Are my decks backed up?
Flipnem runs on redundant cloud infrastructure that is backed up nightly.
Can I get more storage?
Yes — Scholar users can purchase additional storage from the Accounts page.
How do I export my decks?
Open your deck in Flipnem and use the export option to download a standard .apkg file. Exports are available on the Scholar plan.
Is there a mobile app?
Flipnem is a Progressive Web App (PWA). On iOS or Android, open flipnem.com in your browser and tap "Add to Home Screen" to install it.
Can I create cards with images in Flipnem?
Yes. When creating or editing a card, you can attach images directly from your device or camera. Images are displayed in Study and Review mode on all devices. Audio and video are supported when imported via .apkg but cannot be added manually at this time.
