Estimates how long today's Anki reviews will take and tracks live progress, pace, and remaining time across all decks based on recent average review times.
Description
DDL Oracle answers one question: "How long until I reach my learning goal?"
Given your recent review history, it predicts a deadline (DDL) for each goal level in whatever subject you are studying. A new installation starts with a neutral task scaffold that tracks all decks as one card type, without any subject-specific curriculum. Add specific deck paths to split card types for language learning, exams, or custom curricula.
What it shows
A small panel below the deck list, with one row per level:
- progress percentage (weight-adjusted across card types)
- estimated completion date
- days remaining
Progress tracks cards assigned to each level by study history: a card is counted once it has at least one review-history entry. This is separate from mastery; a card does not need to reach the mastery interval threshold to be assigned to a level.
How it works
The prediction combines three signals taken straight from your revlog:
- Per-type expansion β average reviews a card of that type takes to reach the mastery interval configured by the user.
- Card-type weights β different card types take different amounts of time per review. Auto-calibrated from your real review times.
- Recent effort β weighted reviews per calendar day over the last N days (default 7), excluding reviews whose post-review interval is at or above the configured mastery threshold.
days_remaining = Ξ£ (gap Γ weight Γ expansion) / effort_per_day
No growth model, no retention factor β expansion empirically encodes
failures and relearning.
Configuration
Tools β DDL Settingsβ¦ opens a 3-tab dialog:
- General β DDL title, effort window, mastery threshold, algorithm hint, deadline
- Card Types β define card categories using exact deck paths;
*catches other decks - Level Targets β how many cards of each type are assigned to each level; assignment starts with the card's first review-history entry and is separate from mastery
Weights are auto-calibrated; you don't edit them by hand.
