markdown-to-anki 0.1.2

Convert Markdown files into Anki cards via AnkiConnect

Markdown to Anki

markdown-to-anki is a lightweight Python CLI that automatically converts raw Markdown files into Anki cards using AnkiConnect. It's designed for learners and note-takers who prefer writing in Markdown and want to seamlessly sync their content into Anki.

Installation

pip install markdown-to-anki

Requires Python 3.10+ and AnkiConnect running in your Anki app.

Getting Started

Open Anki, then run:

m2a --folder ~/notes/anki init all

This creates the note models and imports your media and notes. After that, sync anytime with:

m2a --folder ~/notes/anki anki sync

Commands

Command	Description
m2a init all	Create/update Anki note models, then import media and notes.
m2a anki check	Verify the AnkiConnect server is reachable.
m2a anki init	Create/update Anki note models only.
m2a anki sync	Import media and notes, then trigger an AnkiWeb sync.
m2a anki sync_web	Trigger an AnkiWeb sync only (no re-import). Useful for cron.

Only files modified within the last TIME_RANGE seconds (default 2 hours) are processed.

Configuration

Settings are resolved in this order — highest priority wins:

CLI flag  >  environment variable / .env  >  config file  >  default

CLI flags

m2a --folder ~/notes/anki --url http://localhost:8765 anki sync
m2a --resources ~/my-templates init all

Flag	Description	Default
--folder	Path to your Markdown notes dir	see Config file
--url	AnkiConnect URL	http://localhost:8765
--resources	Path to custom card templates/styles directory	built-in resources

Config file

Create ~/.config/markdown-to-anki/config.yaml (respects $XDG_CONFIG_HOME):

md_folder: ~/notes/anki
time_range: 7200
anki_url: http://localhost:8765
resources_dir: ~/notes/anki-templates

Environment variables / .env

Place a .env file in the directory where you run m2a, or set the variables in your shell:

MD_FOLDER=~/notes/anki
TIME_RANGE=7200
ANKI_URL=http://localhost:8765
M2A_RESOURCES_DIR=~/notes/anki-templates

Markdown Style

Each Markdown file may contain one or more cards. Use YAML frontmatter for per-file metadata and the comment separators below to split cards and fields:

---
deck: M2A::Example::Math
tags: math, theorem
model: m2a-basic
# skip: 1   # uncomment to skip this file
---

<!--CARD-->

### Front of card 1

<!--FIELD-->

Back of card 1

<!--CARD-->
<!--TAGS: hard, exam-->

### Front of card 2

<!--FIELD-->

Back of card 2

Supported metadata keys: deck, tags, model, skip.

Per-card tags via <!--TAGS: a, b--> (anywhere inside a card section) are merged with the file-level tags from frontmatter.

Built-in note types

Model	Fields	Description
m2a-basic	Front, Back	Simple front → back card
m2a-basic-reverse	Front, Back	Front → back and back → front
m2a-cloze	Text, Extra	Cloze deletion card
m2a-english	Word, Audio, Meaning	Vocabulary card with audio support

Cloze cards

Use Anki's native {{c1::...}} syntax in the Text field. Multiple deletions (c1, c2, …) are supported in a single card.

---
deck: M2A::Example::Cloze
model: m2a-cloze
---

<!--CARD-->

The capital of {{c1::France}} is {{c2::Paris}}.

<!--FIELD-->

European geography.

<!--CARD-->

{{c1::Water}} boils at {{c2::100}}°C at standard pressure.

<!--FIELD-->

Basic chemistry fact.

The Text field holds the cloze content; Extra is shown on the back and can hold supplementary notes.

Custom Resources

Point --resources (or resources_dir / M2A_RESOURCES_DIR) at your own directory to override built-in templates/styles and define new note types. Only the files you provide are overridden — everything else falls back to the built-in defaults.

Override built-in templates or styles

Mirror the built-in layout under your resources directory:

my-resources/
└── anki/
    ├── styles/
    │   └── basic.css          # overrides the built-in basic.css
    └── templates/
        └── basic/
            └── front.html     # overrides the built-in front template

Define custom note types

Place a YAML file per model inside a models/ subdirectory:

my-resources/
├── models/
│   └── my-vocab.yaml
├── styles/
│   └── my-vocab.css
└── templates/
    └── my-vocab/
        ├── front.html
        └── back.html

models/my-vocab.yaml:

name: my-vocab
fields:
  - Word
  - Definition
  - Example
is_cloze: false
css_file: styles/my-vocab.css      # relative to my-resources/
templates:
  - name: word-to-definition
    front_file: templates/my-vocab/front.html
    back_file: templates/my-vocab/back.html

Inline CSS and HTML are also supported instead of file references:

name: my-simple
fields:
  - Question
  - Hint
  - Answer
css: ".card { font-family: sans-serif; }"
templates:
  - name: card
    front: "<div>{{Question}}</div><div class='hint'>{{Hint}}</div>"
    back: "<div>{{Answer}}</div>"

Fields map to <!--FIELD--> sections in order. A card with three fields uses two separators:

---
model: my-vocab
deck: Languages::English
---

<!--CARD-->

hello

<!--FIELD-->

A common English greeting.

<!--FIELD-->

"Hello, how are you?" — used when meeting someone.

Run m2a --resources my-resources/ init all to register your models in Anki before syncing notes.

Limitation

• DO NOT use dark theme in Anki — the rendered Markdown style does not support it.
• Attachments (images, audio) must be placed in the same directory as the Markdown file, or a subdirectory of it.

Cronjob

Automatically sync your notes to AnkiWeb hourly:

crontab -e

# sync hourly (replace /usr/local/bin/m2a with the output of: which m2a)
5 * * * *  /usr/local/bin/m2a --folder ~/notes/anki anki sync_web &>/dev/null

Examples

See the example notes for working Markdown files covering basic cards, cloze deletions, math, code, and audio.
