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
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.
Simple, transparent pricing
* Additional storage available at $0.20 / GB per month.

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-6 (Free Spaced Repetition Scheduler), running right on your device. 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 any device, resulting in an application that feels local. See the install instructions for each platform and browser.
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.
