TROZUNLearning OS
Focus System Active

Effort that actually sticks.

Trozun reads your professor's past papers, learns how they test, remembers what you get wrong, and picks what you study next. Most study apps just make flashcards faster.

What we built that isn't the LLM

The model is the cheap part.

Trozun reads your professor's past papers, learns how they test, remembers what you get wrong, and picks what you study next. Most study apps just make flashcards faster.

01 · Prof profile

Trozun reads your professor.

We extract a structured profile from your prof's past papers and slides — their notation, their trap patterns, their cognitive-style mix. Every answer Trozun writes speaks in their voice, not a textbook's.

02 · Mistake-aware tutor

Every wrong answer changes the next reply.

MistakeLog tracks every miss with an error tag, recency- decays it, and feeds the tutor's system prompt before it answers. By visit three, Trozun explains things specifically the way you keep getting them wrong.

03 · Cross-class linking

The same sign error in chem and calc is the same gap.

When the same kind of mistake appears in two of your classes, the tutor flags the pattern. No competitor in the category does this — their architectures don't correlate errors across courses.

04 · Auto-route

We pick what to study next so you don't.

One utility score per topic combines exam urgency, mistake count, mastery gap, and Ebbinghaus interval. Open Trozun; the timer counts down; you're in the right drill before you had to evaluate options.

Visible mechanism

The actual intervals Trozun queues for you.

Forgetting decays exponentially — each review re-anchors the trace. The dashed lines mark the days Trozun pulls a dot-point back into your queue, calibrated to your mastery.

The Methodology

Procedural workflow.

Step 01

Capture

Step 02

Plan

Step 03

Study

Step 04

Review

Repeat

Capture → Plan → Study → Review — the repeatable loop
STEP 01

Ingest Context

Upload raw lectures, PDFs, or unstructured notes. Trozun breaks down massive textual data into fundamental structural concepts.

STEP 02

Concept Mapping

Shows you which topics from one course connect to topics in another, so you can study them together.

STEP 03

Mastery Validation

Automated retrieval checkpoints validate your true understanding. Weak-spot detection dynamically schedules exactly what you need to review tomorrow.
