SmartFlow turns knowledge into question-and-answer cards and schedules reviews based on previous answers, without requiring a manually maintained study plan.
Overview
The problemCreating flashcards is only the beginning. Learners also need to know what to review, when to revisit it, and how they are progressing without juggling multiple tools.
The solutionOne app combines card creation, organization and recall sessions. A scheduling engine computes due dates, while a dashboard brings together pending cards and progress indicators.
Enter a question, optionally select a category, then add its answer in a guided flow. The card is saved and can immediately be opened for its first review.

The React interface calls Next.js API routes, where review logic runs and data is read or updated through Prisma and PostgreSQL.

Cards, categories, accounts and review historyLevel rules spread across UI screens can produce inconsistent dates, especially around day boundaries.
A single domain module calculates due dates, overdue days and progression using Europe/Paris as the reference time zone.
A card’s latest review date cannot reconstruct historical activity or consistency across sessions.
Each assessment updates the card and writes a review-log entry within the same Prisma transaction.
An empty account, a new learner and an active learner each need different progress information.
A data calculator isolated from database access produces dashboard tiles and states tailored to each account’s situation.
Main technical stack
Card creation, organization, daily queues, answer reveals and level-based progression work together in one application.
The dashboard shows cards due, mastery levels, categories and indicators built from the review log.
