This add-on automatically saves the contents of the Add Cards window every few seconds, so you never lose work if:
- Anki crashes
- Your laptop runs out of power
- You accidentally close the Add window
- Another add-on misbehaves
- The OS freezes or reboots
If you reopen the Add window with the same note type, your draft will be restored automatically.
🚀 Features
✔ Automatic autosave
- Saves every N seconds (default: 5 seconds).
- Saves all fields + tags.
- Very lightweight, no noticeable performance impact.
✔ Separate drafts for each note type
Each note type (Basic, Cloze, Custom types) stores its own independent draft.
✔ Timestamp-based protection
- Each draft has a
last_saved timestamp.
- Drafts older than a configurable age (default: 48 hours) are ignored and cleaned automatically.
- Prevents old drafts from “coming back from the dead.”
✔ Safe behavior
- Draft is deleted only after the note is successfully added.
- Never touches Anki’s database directly.
- Writes only tiny JSON files → very low overhead.
🛠 Installation
- Open Anki.
- Go to: Tools → Add-ons → Open Add-ons Folder
- Create a folder, for example:
addons21/
add_cards_autosave/
__init__.py
README.md
- Place
__init__.py inside that folder.
- Restart Anki.
⚙️ Configuration
Inside __init__.py, you can customize:
Autosave interval
AUTOSAVE_INTERVAL_MS = 5000 # 5 seconds
Maximum draft age
MAX_AGE_SECONDS = 48 * 60 * 60 # 48 hours
Where drafts are stored
Drafts are saved in:
<your Anki profile folder>/add_cards_autosave.json
Each draft is stored by note type:
{
"Basic": {
"last_saved": 1732690000.123,
"fields": ["Front", "Back"],
"tags": ["tag1"]
},
"Cloze": { ... }
}
🔒 When drafts are restored
A draft is restored only if all are true:
- The note type matches
- Draft is not older than
MAX_AGE_SECONDS
- JSON entry contains valid fields
Otherwise, the draft is ignored.
🧹 When drafts are deleted
A draft is removed only when a note is successfully added or discarded (Add window closed manually).
Drafts are not deleted when:
- You switch note types
- Anki crashes
- The OS shuts down unexpectedly
This ensures your work is always recoverable.
❗ Compatibility
- Works with Anki 2.1.60+
- Should work with earlier versions with minimal changes
- Compatible with most editor add-ons
- Light enough for slow/older machines

🧩 Why this add-on is helpful
The Add Cards window does not autosave by default.
If you’ve ever:
- Spent 10–20 minutes writing a detailed card
- Experienced a crash or laptop power loss
- Reopened Anki to find your card completely gone
…this add-on solves that forever.
It gives Anki a “draft safety net” that many users wish it had built in.
🙋 FAQ
Q: Will autosaving every 5 seconds slow down my PC?
A: No. Each autosave writes a tiny JSON file (1–5 KB).
CPU and disk impact are effectively zero.
Q: Does it autosave images / LaTeX?
A: It autosaves whatever is in the fields — including image references and LaTeX code.
Q: Does it work with multi-line fields / HTML?
A: Yes, everything is stored as plain text in JSON.
Q: How do I test the add-on?
A: Write notes in the Add Card Window, next open task manager, then right-click on the Python processes running under "Apps" and click "End Task", after that relaunch Anki, and finally reopen the Add cards window. The draft should be restored.
