    Didata Score reads retention, performance, regularity, and consolidation for each subject to turn progress into direction. Instead of just showing a number, it points to what to review now, what needs reinforcement, and where you can keep moving forward.

    This week's focus
    Today's recommendation

    Review 4 Krebs flashcards today to get Biology back into rhythm.

    You barely revisited this topic across different study formats this week.

Progress with direction

Don't use progress only to look back. Use it to decide what to do now.

Didata tracks every subject and turns study signals into practical guidance: what to review, where to push harder, and what's already improving.

  1. Each subject shows your real priority

    Didata Score summarizes where that subject stands so you do not waste energy interpreting the dashboard. In seconds, you can tell whether it is time to rebuild the basics, reinforce review, or keep your momentum.

  2. The signals explain the recommendation

    Retention, performance, regularity, and consolidation show why that suggestion appeared. When one drops, you can tell whether you need more review, more practice, more consistency, or broader contact with the topic.

  3. A recommendation you can act on right away

    ‘Review 8 physiology flashcards before bed.’ ‘Redo the 3 mixed-chemistry questions you missed on Monday.’ Specific enough to act on — today, in the time you have.

  4. Your history helps you adjust your routine

    The heatmap shows when you disappear, when you lock in, and when you perform best. That helps you plan the next week from what is actually happening, not from guesswork.

AI for studying

An AI that belongs in your study routine.

Not a general-purpose chatbot. A purpose-built study AI — with the right formats, the right focus, and real limits on what it touches.

  1. Built for learning, not chatting

    Notes, flashcards, exercises, mind maps, essay feedback — every output is shaped for how people actually study, with formats, difficulty levels, and review cadence that match the material.

  2. Grounded in your material

    Everything is generated from your PDFs, videos, audio, text, or our curated question bank — and the source sits right behind every answer so you can verify it.

  3. Your data stays yours

    LGPD-compliant, with full deletion on request. Nothing you upload trains any model — ours or anyone else's.

Real students, real routines.

ENEM, entrance exams, medical residency, public tenders, college — same Didata, different finish lines.
