Thirteen product surfaces from Chameleon's insight and analytics system, rebuilt as standalone Marginalia sections for landing-page use. Each one shows what it does, what data it is computed from, and a ready-to-use landing line.
Not a completion bar. Readiness weights every knowledge atom by how critical it is and how likely it is to be examined, then compares you against the pace you would need to hit your target by exam day.
Flashcard apps ask you to grade yourself, then believe you. Chameleon measures each student's self-grading bias and corrects for it, blends in objective quiz evidence (keyed answers, AI-graded written work), prices in the whole syllabus, and projects the result to exam day.
Every card carries a live memory model. Chameleon projects each one forward and warns you which topics you know today will have faded below target by exam day.
Ten behavioral rules read your study exhaust and only speak when the sample size clears a threshold. Every insight carries its evidence and an honesty badge, and low confidence is labeled a hypothesis, never a fact.
11 cards are "leeches", you keep forgetting them. They're eating your review time; tackling them directly is the highest-leverage fix.
Your accuracy drops off in long sessions: 57% in 45-minute-plus sittings vs 75% in your shorter ones. Shorter, more frequent sessions keep retention higher.
Your written answers on "Income and Substitution Effects" are coming up short, averaging 1.3/10. That usually points to an understanding gap rather than a memory one.
No leaderboards, no peer pressure. Chameleon snapshots readiness weekly and reports the delta against you, and only you.
Before every review, the memory model predicts your recall odds. Chameleon keeps score of prediction vs outcome, so overconfidence shows up as a measurable gap, not a feeling.
Multiple choice flatters you. Chameleon splits accuracy by question type and exposes the gap between recognizing an answer and producing one.
Chameleon aggregates accuracy by hour of day and finds your peak window, then the insight engine suggests scheduling your hardest material inside it.
Accuracy by how long you've been sitting. When your long sessions measurably underperform your short ones, the fatigue insight fires with the numbers.
The research says spaced beats crammed (d≈0.85, the strongest effect in learning science). The heatmap makes your spacing, or your cramming, impossible to miss.
Interleaved practice strengthens long-term retention. Chameleon scores how much you mix chapters within sessions against the research-backed 40–60% zone.
Not your lowest scores. Chameleon ranks by exam weight × weakness, so a shaky core concept outranks a shakier footnote, and tells you what has never been tested at all.
Everything is generated from the student's own uploads, so mastery can be attributed back to each file. A low-mastery source is a re-read candidate.
Chameleon decomposes your material into typed knowledge atoms (definitions, procedures, computations…) and tracks each one: mastered, shaky, or never yet tested. This is the substrate every other number rolls up from.
