Why safety architecture matters

AI-powered bulk edits can transform how you manage flashcards, but they also introduce new risks. Unlike individual card edits where mistakes are isolated, bulk operations can affect hundreds of cards in seconds. This is why we built safety controls into every AI bulk workflow from day one.

This page explains our risk model, the safeguards we implemented, and how you can use these controls effectively. We believe transparency builds trust — understanding how safety works helps you use AI features with confidence.

Risk Model for Bulk Operations

We identified four primary risk categories when designing AI bulk edit safety:

Risk	Description	Mitigation
Data loss	Irreversible changes to cards or decks	Confirmation gates, rollback capability
Quality degradation	Bulk edits that lower card quality	Preview mode, sample validation
Scope creep	Operations affecting more cards than intended	Clear count limits, explicit deck targeting
Format corruption	Changes that break card structure	Template validation before execution

Confirmation Gates and User Consent

Every bulk operation passes through multiple confirmation gates. Here's how they work:

Intent declaration

User must explicitly state what they're trying to accomplish before AI executes.

Example: Before running bulk replace, user confirms: 'Replace all instances of X with Y in deck Z'

Scope preview

AI shows exactly which cards will be affected before making changes.

Example: Preview displays: '23 cards will be modified. Here's a sample of 5.'

Confirmation prompt

Explicit user action required to proceed after preview.

Example: UI requires clicking 'Confirm' — not just pressing Enter — to proceed.

Execution limits

Bulk operations are capped to prevent catastrophic mistakes.

Example: Maximum 100 cards per bulk operation. Larger decks require staged batches.

Operational Limits and Loop Safeguards

Beyond confirmation gates, we implemented several operational safeguards:

All destructive operations require at least one confirmation step.
Users see affected card count and sample before execution.
Operations are logged for audit and rollback if needed.
Free tier has reduced operation limits compared to paid plans.
Template validation prevents format corruption.
Batch staging allows users to pause between chunks.

These safeguards apply to all users regardless of plan. Pro users get higher operation limits, but safety controls are identical across tiers.

Practical Recommendations for Users

Get the most out of AI bulk edits while staying safe:

1
Start with a small test deck before running bulk operations on your primary decks.
2
Always review the preview — check that affected card count matches your expectations.
3
Use batch operations for large decks instead of single large operations.
4
Keep backups of important decks before running unfamiliar bulk workflows.
5
Check operation logs after bulk edits to verify expected changes were applied.

Frequently asked questions

Can AI accidentally delete my entire deck?

No. Deckbase does not allow bulk delete operations. The most destructive action is bulk modification, which always requires explicit confirmation and shows a preview of affected cards before execution.

What happens if I confirm by mistake?

Most bulk operations can be reversed. If you make a mistake, contact support within 24 hours for restoration. We recommend backing up important decks before running unfamiliar bulk operations.

Are there limits on how many cards I can edit at once?

Yes. Free tier allows up to 50 cards per bulk operation. Pro users can edit up to 100 cards at once. Larger operations should be split into batches for safety.

Does AI ever modify cards without asking?

Never. Every bulk modification requires explicit user confirmation. Even simple changes like adding a tag require confirmation before execution.

Can I preview what the AI will do before confirming?

Yes. The preview step shows affected card count and a representative sample. This lets you verify the operation scope matches your intent before committing.

How do I know if the bulk edit worked correctly?

After execution, the system shows a summary with success count and any failures. Failed cards are marked for review. You can always check the operation log for details.
