Daily Load

How many cards you’ll review per day, on average, over the next 30 days. A higher number means your deck is growing faster than you’re reviewing.

FSRS adds slight randomness to intervals, keeping cards from piling up on the same day.

iAverage cards you’ll review per day over the next 30 days

i

Groups cards by due date, counts overdue + new as today, averages across 30 days

i

If this spikes after adding cards, slow down on new material until reviews settle

Daily Load in the Memory tab. Your baseline depends on how many cards you have. A spike means new cards are adding to your upcoming schedule.

Predicted Retention

How likely you are to recall each learned card right now, averaged across all your cards. Uses the FSRS forgetting curve — compare with True Retention to see how well the model matches reality.

i

Probability you could recall each learned card right now, based on FSRS’s memory model

i

Uses days since last review + card stability to apply the forgetting curve per card

i

Theoretical estimate — compare with True Retention to see if the model matches reality

Predicted Retention at 96.3%. FSRS targets 90% by default — a higher number means cards are reviewed before you’d forget.

True Retention

How often you actually pass your cards. Only counts reviews with 1+ day intervals — the ground truth of Predicted Retention.

iHard, Good, or Easy counts as a pass. Again counts as a fail.

iOnly counts reviews with 1+ day intervals. Pass = Hard, Good, or Easy. Fail = Again.iIf predicted >> true, the algorithm overestimates your memory. Ideally they’re close.

True Retention at 97.6%. Compare with predicted retention — when they’re close, the algorithm has a good model of your memory.

Card States

How your cards are distributed across four states. Color-coded per deck on the Memory tab.

i

Memory strength score for this deck. It combines progress, retention, and review history

i

New → Learning → Review. If forgotten, cards move to Relearning until relearned.

Card states per deck on the Memory tab. Over time, cards naturally shift from New to Review as you learn them.

Lapses

How many times you’ve forgotten cards that you’ve already learned. Each lapse helps FSRS refine its scheduling.

i

Total times you pressed “Again” on already-learned cards. It helps FSRS adjust difficulty

i

How many of your cards have been forgotten at least once. 6 out of 49 here.

i

Lapses only count after initial learning. Pressing “Again” while first learning doesn’t count.

Times Forgotten and Cards with Lapses. FSRS uses lapses to fine-tune difficulty and interval calculations.

Deck Descriptions

How to give the card generation model context about your deck. Set a description once and cards match that level.

i

Descriptions appear under each deck name, e.g. “Calculus Highschool”, “Spanish A2 Vocabulary”, etc.

i

Editable description. Add subject, difficulty level, or focus area

Deck description field. Set your subject, difficulty level, or focus area once — it feeds directly into card generation.

Smarter Generation

How the card generation model already knows what you’re learning. Your deck name, description, and existing cards are all fed in as context.

i

Chat model reads deck name + description automatically — no need to repeat yourself

Generating cards for “Math — Calculus Highschool”. The model picks up the deck name and description.

Generation Loss Prevention

What happens when you try to leave mid-generation or discard unsaved cards. Chat history isn’t kept — these dialogs prevent accidental loss.

i

Warning when leaving during active generation — prevents losing progress

i

Warns before discarding unsaved cards — protects your credits too

Confirmation alerts during card generation. These appear before you can leave or discard unsaved work.

Drill Card Stats

What FSRS knows about each card. Difficulty, stability, and current recall displayed during drill sessions.

i

Grade from Again (forgot) to Easy. Each grade adjusts the card’s next review interval

i

Per-card FSRS stats: difficulty (out of 10), stability (days until forgetting), and current recall %

Per-card FSRS stats during drill. See difficulty, stability, and current recall as you review each card.
