Anki out of the box is powerful, but it's also... bare-bones. The default interface looks like it was designed in 2006 (because it was), and many features that med students depend on require add-ons or external tools.
After years of collective wisdom from r/medicalschoolanki, the AnKing community, and thousands of students, certain add-ons and tools have become essentially mandatory for a productive medical school Anki setup.
Here's an honest rundown of the best ones in 2026, organized by what they actually do for you.
Essential Add-ons (Install These First)
AnKing Note Types
What it does: Provides the standardized note types used by the AnKing deck — the most popular pre-made Anki deck for USMLE prep.
Why it matters: Even if you don't use AnKing, these note types are well-designed. They support cloze deletions with hint hotkeys, toggleable extra fields, and clean formatting. If you're downloading shared decks from classmates, chances are they use AnKing note types.
Verdict: Essential if you use any pre-made medical Anki deck.
Image Occlusion Enhanced
What it does: Lets you create image occlusion cards — take a diagram or figure, draw boxes over labels or structures, and Anki tests you on each one individually.
Why it matters: Anatomy, pathology, histology, and radiology are inherently visual. Text-based cards can only do so much when you need to identify the location of the brachial plexus or the layers of the retina. Image occlusion turns diagrams into active recall exercises.
Limitations: Creating cards is still manual — you screenshot the image, paste it in, and drag rectangles over each label. For a complex anatomy diagram with 15 labels, this takes several minutes per image.
Verdict: Must-have for any visual subject. The creation process is tedious but the cards are incredibly effective.
Review Heatmap
What it does: Adds a GitHub-style contribution heatmap to your Anki home screen showing your daily review activity over time.
Why it matters: Consistency is everything with spaced repetition. The heatmap gives you a visual streak tracker that motivates daily reviews. It also shows your forecast — how many reviews are coming up in future days — so you can plan around exams.
Verdict: Low-effort, high-impact. Makes it psychologically harder to skip a day.
Special Fields
What it does: Protects your personal edits when updating shared decks. Without it, updating the AnKing deck would overwrite any custom hints, mnemonics, or notes you've added to cards.
Verdict: Essential if you use AnKing or any shared deck that gets periodic updates.
FSRS (Built-in Since Anki 23.10)
What it does: A modern scheduling algorithm that replaces Anki's default SM-2 algorithm. FSRS uses machine learning to optimize review intervals based on your actual performance data.
Why it matters: Better scheduling means fewer reviews for the same retention. Students who switch from SM-2 to FSRS typically report a 10-20% reduction in daily review load while maintaining the same pass rate.
How to enable: Settings → Deck Options → FSRS toggle. It's built into Anki now — no add-on needed.
Verdict: Free performance boost. No reason not to use it.
Productivity Add-ons
Edit Field During Review (Cloze)
What it does: Lets you edit the current card without leaving the review screen. See a typo or want to add a mnemonic? Click the field and fix it in place.
Why it matters: The friction of "I should fix this card... but I'd have to open the editor..." means most small fixes never happen. This add-on eliminates that friction.
BetterSearch
What it does: Improves Anki's browser search with autocomplete, search history, and better filtering.
Why it matters: When you have 30,000+ cards, finding specific ones matters. The default search is functional but clunky.
Advanced Browser
What it does: Adds more columns to the card browser — interval, ease, number of reviews, etc.
Why it matters: Useful for identifying "leeches" (cards you keep failing) and understanding your deck statistics.
External Tools and Companions
AnKing Deck + AnKing Website
The AnKing deck is the de facto standard for USMLE Step 1 and Step 2 content. It's a curated, tagged, and regularly updated deck built on Zanki, Lolnotacop, and other community decks.
Best practice: Use AnKing for boards content and supplement with your own lecture-specific cards. Don't try to replace AnKing — supplement it.
The AnKing website and YouTube channel also have excellent tutorials on Anki setup, add-on recommendations, and study strategies.
SlideToAnki
What it does: Upload a lecture PDF or PowerPoint, and AI generates Anki flashcards from it — cloze deletions, Q&A cards, and image occlusion cards. Export as .apkg.
Why it matters: This solves the biggest Anki pain point for med students: the time it takes to create cards from lectures. Most students spend 2-3 hours per lecture making cards manually. SlideToAnki compresses that to a few minutes.
What's unique: It handles diagrams automatically. The AI detects labels on anatomy diagrams, pathology images, and other figures, then generates image occlusion cards without you having to manually draw boxes. It also uses a smart card count that adapts to slide density — a content-heavy biochemistry lecture generates more cards than a light intro lecture.
Verdict: Fills a gap that no add-on can solve. Add-ons improve Anki itself; SlideToAnki solves the card creation bottleneck.
Anki Connect
What it does: Provides an API for external applications to interact with your Anki collection — add cards, query decks, etc.
Why it matters: Powers various integrations and workflows. Some students use it with custom scripts to import cards from other sources.
RemNote / Notion-to-Anki Pipelines
Some students take notes in RemNote or Notion and export to Anki. These workflows can work, but they add complexity and the card quality depends heavily on how you structure your notes. For most students, making cards directly (manually or with AI tools) produces better results.
Add-ons to Avoid (Or Use Carefully)
Speed Focus Mode / Auto-Reveal
These add-ons auto-flip cards after a timer. In theory, they prevent spending too long on any one card. In practice, they create anxiety and encourage superficial review. Spaced repetition works because you think hard about each card — rushing defeats the purpose.
Addons That Change Review Order
Unless you have a specific reason, stick with Anki's default review order (or FSRS-optimized order). Random or custom ordering can mess with the spacing algorithm's assumptions.
Recommended Setup for 2026
If you're starting fresh, here's the setup I'd recommend:
- Install Anki (desktop version, not AnkiWeb)
- Enable FSRS in deck settings
- Install: AnKing Note Types, Image Occlusion Enhanced, Review Heatmap, Special Fields, Edit Field During Review
- Download AnKing deck for board-relevant content
- Use SlideToAnki for lecture-specific cards
- Tag everything by lecture, organ system, and exam block
- Review daily — even 15 minutes on a busy day is better than nothing
The goal isn't to have the fanciest Anki setup. It's to minimize friction between "I learned something in lecture" and "I'm actively recalling it in Anki." Every add-on and tool on this list should make that pipeline faster or smoother. If it doesn't, you don't need it.
Final Thoughts
Anki's strength is its simplicity and its algorithm. The add-on ecosystem fills in the gaps — better note types, visual cards, streak tracking, and now AI-powered card creation. You don't need everything on this list, but the essentials (AnKing Note Types, Image Occlusion, Review Heatmap, FSRS) are worth setting up on day one.
The biggest time sink for most students isn't Anki itself — it's making the cards. If that's your bottleneck, look at tools that automate the creation process rather than adding more add-ons to the review process.
