Saving the humans, one Flashcard at a time
An Anki compatible hosted flashcard platform
Why Flipnem
Take ownership of your learning.
Flipnem is a lightweight and device-independent flashcard platform that uses FSRS spaced repetition to intelligently ensure you are maximizing your studying time.
Leveraging Flipnem's ability to create custom decks — either by hand or using AI — the modern student can take ownership of and optimize their learning.
Whether on your computer or on your phone, Flipnem offers a single web interface so that you can study anywhere.
You can even install it on your phone's home screen — as a Progressive Web Application — for a seamless experience.
Features
Everything you need to make learning stick
Card Styling
Add your signature style to any deck
Choose a background color and typography for any deck.
- Color picker lives in the study viewer — change it without leaving your session
- Set a global default in Settings for all new decks
- Per-deck overrides
Typography controls per deck:
- Font size — scale text up or down
- Serif vs sans-serif font
- Left vs center justification
Public Profile
Your progress, public if you want it
Every Scholar account gets a public profile page — a permanent URL that shows the world what you have been learning. Share it in your bio, a class introduction, or just keep it for yourself.
- 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
Deck Encryption
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.
Rich Card Rendering
Bring your cards to life with 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
Fenced code blocks get instant syntax highlighting — Python, Rust, SQL, and dozens more languages.
Mermaid diagrams
Embed flowcharts, sequence diagrams, ER diagrams, and more. Ideal for system design, architecture, and process cards.
ABC music notation
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 and display math render beautifully — Anki decks with MathJax tags come through correctly too.
Deck Creation
Own your learning destiny
Write your own cards
- Create and edit cards right in the browser editor
- Inspect and tweak any card mid-session, then pick up right where you left off
- Add images to any card
- Rich Card Rendering brings math, code, tables, and more to life
Note types
Basic — the Anki Basic note type, a simple Front / Back card
Flipnem Basic Default — adds a dedicated mnemonic field
Cloze — blank out key terms inside a sentence
Source Note — reference material, never scheduled for review
See all note types ↗Let AI do the heavy lifting Scholar+
- Connect any MCP-compatible AI assistant to your Flipnem account
- It reads your decks and Source Notes and builds sub-decks from your material
- Populates cards to your preferences
- Runs your due cards as an interactive quizmaster — ratings go straight to FSRS
- Stores your mnemonic devices in the deck's memory and surfaces them as hints
Setup
Flipnem MCP setup is trivial. Contrast this with Anki, which requires running AnkiConnect locally and you managing the backend.

Support & FAQ
How can I get a deck so I can play with Flipnem?
Visit Sam's public profile and import any of the Shared Decks.
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.
What algorithm does Flipnem use for Spaced Repetition?
Flipnem uses FSRS-5 (Free Spaced Repetition Scheduler). FSRS is on by default — no setup, no tuning required to get modern spaced repetition.
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.
How can I install the Flipnem PWA?
The Flipnem PWA (Progressive Web App) can be installed on Mac, Windows, Linux, iOS, and Android devices. This will result in an application that feels local.
If you are on a Chrome browser and see an "Install Flipnem" button here then you can click that to install the PWA. If you are on iOS, you will need to install it manually. For this webpage: tap Share → Add to Home Screen in Safari.
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.
