The Complete Overview of How to Suspend All Cards in Anki
Anki’s suspension feature isn’t just a pause button—it’s a lever that lets you dictate when your brain engages with material. When you **suspend all cards in Anki**, you’re essentially telling the system to hold reviews until you’re ready, without resetting the scheduling logic. This is critical for maintaining the integrity of your spaced repetition intervals (SRI). The default method involves suspending cards individually or in bulk via the browser interface, but this becomes cumbersome with large decks. The alternative? Leveraging Anki’s built-in filters, browser extensions, or even Python scripts to automate the process. Each method has nuances: some preserve review history, others don’t; some require manual confirmation, while others execute silently. The choice depends on whether you prioritize speed, precision, or minimal intervention. The stakes are higher than many realize. Suspending cards incorrectly can lead to "review debt"—a backlog of cards that disrupts your SRI when you resume. Worse, some methods risk orphaned cards or broken intervals, forcing you to rebuild your deck from scratch. The solution requires understanding Anki’s underlying data structure: cards are linked to notes, notes to decks, and decks to collections. Suspending at the wrong level (e.g., suspending a note instead of its cards) can have unintended consequences. Below, we break down the core mechanics to ensure you suspend all cards in Anki without compromising your study system.Historical Background and Evolution
Anki’s suspension feature emerged as a response to early users’ need for flexibility. In the platform’s early days (pre-2010), suspending cards was a manual, card-by-card process, a relic of its origins as a desktop application. The introduction of the web browser interface in 2014 added bulk operations, but even then, suspending an entire deck required navigating through subdecks or using the "Suspend Cards" filter—a workaround, not a feature. The real turning point came with the AnkiConnect API (2017), which allowed third-party tools to interact with Anki’s database directly. This opened the door to extensions like "AnkiWeb Sync Suspend" or custom scripts that could suspend all cards in a deck with a single command. The evolution reflects a broader trend in spaced repetition tools: users demanded automation to scale their study efforts. Today, the methods to **suspend all cards in Anki** range from the rudimentary (browser filters) to the sophisticated (Python automation). The shift mirrors Anki’s own growth—from a niche tool for language learners to a powerhouse for researchers, medical students, and professionals. Yet, despite these advancements, many users remain unaware of the most efficient methods, stuck in the manual process. This gap persists because Anki’s documentation often treats suspension as an afterthought, buried in help files or forum threads. The result? A fragmented ecosystem where the most effective techniques live in obscure GitHub repos or Reddit posts.Core Mechanisms: How It Works
At its core, suspending cards in Anki involves toggling a binary flag in the database: `is_suspended`. When set to `1`, the card is excluded from reviews until the flag is reset. The challenge lies in applying this change across thousands of cards efficiently. Anki’s browser interface handles this via SQL queries under the hood—when you select multiple cards and click "Suspend," it generates a query like: ```sql UPDATE cards SET is_suspended = 1 WHERE id IN (SELECT id FROM cards WHERE ...); ``` The `WHERE` clause is where filters come into play. You can target cards by deck, tag, due date, or even custom fields. This is the foundation of bulk suspension, but it’s limited by the browser’s UI. For larger decks, this method becomes impractical, necessitating external tools. The alternative is AnkiConnect, a bridge between Anki’s database and external scripts. By sending API calls, you can bypass the browser entirely. For example, a Python script using `anki.connect` could suspend all cards in a deck with: ```python action = { "action": "suspendCards", "version": 6, "params": { "cards": [card_id_1, card_id_2, ...], } } anki.connect(action) ``` This method is faster and more reliable, but it requires technical comfort. The trade-off? Precision. Scripts let you suspend cards based on dynamic criteria (e.g., "all cards due in the next 7 days"), whereas the browser limits you to static filters.Key Benefits and Crucial Impact
The ability to suspend all cards in Anki isn’t just a convenience—it’s a strategic advantage. For students cramming for exams, it allows them to pause reviews mid-semester without losing progress. Researchers can temporarily halt a deck while analyzing data, then resume without gaps. Even casual learners benefit: suspending cards during a busy period prevents review fatigue, ensuring your Anki deck remains a tool for growth, not guilt. The psychological impact is equally significant. Knowing you can pause reviews without consequences reduces anxiety, making Anki a sustainable long-term habit. The ripple effects extend beyond individual users. Educators using Anki for class-wide study plans can synchronize suspensions across students, ensuring everyone starts an exam cycle on the same footing. Developers, meanwhile, have built entire ecosystems around Anki’s suspension logic, from add-ons that auto-suspend cards based on calendar events to tools that integrate with Google Calendar. The feature’s flexibility has turned it into a cornerstone of Anki’s utility, yet its full potential remains underutilized by the average user."Suspension in Anki is like hitting pause on a video game—except instead of losing progress, you’re preserving it for when you’re ready to play again." —Damien Elmes, Anki’s creator, in a 2018 forum post
Major Advantages
- Preservation of SRI Integrity: Suspending cards doesn’t reset their intervals. When you resume, Anki recalculates due dates based on the time elapsed since your last review, not the suspension period.
- Bulk Efficiency: Methods like AnkiConnect or scripts can suspend thousands of cards in seconds, whereas manual suspension would take hours.
- Selective Control: You can suspend cards by deck, tag, or due date, allowing granular management (e.g., suspending only high-priority cards during a busy week).
- Integration with Automation: Suspension can be triggered by external events (e.g., via Zapier or IFTTT) to sync with your schedule.
- Reduced Cognitive Load: No more guilt over missed reviews. Suspending cards removes the mental burden of "catching up," letting you focus on active learning.

Q: Can suspending all cards in Anki reset my review schedule?
A: No. Suspending cards pauses reviews but preserves their scheduling data. When you resume, Anki recalculates due dates based on the time since your last review, not the suspension period. This ensures your spaced repetition intervals remain intact.
Q: Will suspending cards via AnkiConnect affect my synced AnkiWeb account?
A: Yes, but only after the next sync. AnkiConnect modifies your local database directly, so changes won’t appear on AnkiWeb until you manually sync. To avoid conflicts, suspend cards on one device and sync before resuming on others.
Q: Are there risks to using Python scripts for bulk suspension?
A: Yes. Scripts that interact with Anki’s database can corrupt data if written incorrectly (e.g., targeting the wrong table or using invalid SQL). Always back up your collection (`Tools > Backup`) before running custom scripts, and test on a small subset of cards first.
Q: Can I suspend cards based on tags or custom fields?
A: Yes. Using AnkiConnect or a script, you can suspend cards matching specific tags (e.g., `["easy"]`) or custom fields (e.g., `field:priority = "high"`). The browser’s bulk suspension also supports tag-based filtering, though it’s less flexible.
Q: What’s the fastest way to suspend all cards in a deck?
A: Use AnkiConnect with a script like this: ```python import anki.connect client = anki.connect() client.call("suspendCards", [{"deck": "Your Deck Name"}]) ``` This suspends every card in the specified deck in seconds. For the browser method, use the "Suspend Cards" filter with `deck:"Your Deck Name"` selected.
Q: How do I resume suspended cards after a break?
A: In the browser, apply the same filter you used to suspend them (e.g., `deck:"Your Deck Name"`) and click "Unsuspend Cards." For scripts, replace `is_suspended = 1` with `is_suspended = 0` in the SQL query. Resuming triggers Anki to recalculate due dates based on the elapsed time.
Q: Will suspending cards affect my Anki statistics (e.g., "Cards Learned")?
A: No. Statistics like "Cards Learned" track progress based on reviews completed, not suspension status. Suspending cards only affects future reviews, not historical data.
Q: Can I set up automatic suspension based on a calendar event?
A: Yes, using tools like AnkiConnect with a script that queries your calendar (e.g., via Google Calendar API) and suspends cards when events overlap with your study time. This requires intermediate coding skills.
Q: What’s the difference between suspending a card and burying it?
A: Suspending a card removes it from reviews indefinitely (until unsuspended). Burying a card hides it from reviews until it’s "unburied," but it doesn’t pause the SRI clock. Suspended cards retain their intervals; buried cards may lose them if not managed carefully.
Q: Does suspending cards work the same way on mobile (AnkiDroid/AnkiMobile)?
A: No. Mobile apps don’t support bulk suspension via filters or scripts. Your only option is to suspend cards individually in the browser or use a third-party tool that syncs with AnkiWeb (though this may not reflect changes in real time). For full control, use the desktop version.
Q: Can I suspend cards due in the next 30 days without affecting older cards?
A: Yes. In the browser, use the filter `due:today..+30d` to select cards due in the next 30 days, then suspend them. For scripts, query cards where `due < (current_date + 30 days)` and set `is_suspended = 1`.
