The Operational Problem
Learners collect vocabulary from reading and conversations but forget it rapidly. Traditional flashcard apps overwhelm users with streak anxiety, high review backlogs, and cards stripped of original reading context.

Memo
A calm vocabulary retention system designed around context, spaced repetition via the modern FSRS model, and an attention-respecting review rhythm.
User Flow & Ergonomics
Contextual sentence mining via Chrome extension → Automatic tokenization & difficulty indexing → Free Spaced Repetition Scheduler (FSRS) scheduling → High-focus Remember / Forget review surface.
KEY TRADE-OFF // FSRS OVER LEGACY SM-2Adopted the modern Free Spaced Repetition Scheduler to account for memory retrievability and card stability dynamically rather than relying on brittle heuristic decay factors.
Impact & Retrospective
Review sessions feel sustainable over multiple months. Keeping original sentence context dramatically improves recall speed during reading.
LEARNING:The hardest UX challenge in spaced repetition is not the scheduling math—it is preventing review backlog fatigue so the learner actually returns tomorrow.
