Every student knows the feeling.
Nobody's solving it.

100% of HU students already use ChatGPT, Claude, or NotebookLM for studying. None of those tools know what's actually in your course. So students still spend hours figuring out what to study before they can even start.

A few days before the exam, when there is too much material and no clear structure.

— Vu N., HU Student

Too general and not specific enough for the course material.

— Vu N. on ChatGPT

If it reads and knows my work — then yes.

How Cogni works

Three steps. Five minutes. A real study plan.

01

Upload your course

Drop your syllabus, slides, rubric, or past exams. Anything you have — Cogni reads it all.

02

Cogni analyzes

It maps every topic to the grading rubric, weights by exam likelihood, and builds your personalized plan.

03

Study what matters

Ranked topics, time estimates, and practice questions sourced directly from your course materials.

Built on what students actually said

Every feature traces back to a real interview quote.

Reads your actual files

Not generic content. Cogni ingests your syllabus, slides, rubric, and past exams to understand what your specific course tests.

Ranks by grade impact

High-weight topics first. Knockout criteria flagged in red. No more wondering "is this even on the exam?"

Realistic time estimates

How long each topic actually takes — calibrated to the depth your professor expects, not a generic average.

Source-cited answers

Every claim links back to the exact page in your course material. No hallucination. No "trust me" answers.

Practice in your exam format

Viva-style, multiple choice, essay prompts — whatever your professor uses, Cogni generates practice in that exact format.

Your data stays yours

Course files never train any model. Encrypted at rest. Auto-deleted after your exam if you want.

Why not just use ChatGPT?

Existing AI is built for general questions. Cogni is built for one job: helping you ace your specific exam.
