Diagnosis-first learning

Master math by fixing
the exact step you got wrong.

Upload your work. Cognifiy finds the first wrong step, explains why it broke, and generates targeted practice until the concept sticks—not random drilling.

How Cognifiy works

Diagnose → Repair → Retain. Three steps to actual mastery.

1
Diagnose
Upload your work
Take a photo or upload an image. Cognifiy reads your handwriting, identifies each step, and compares against valid solution paths.
2
Repair
See exactly where you went wrong
It marks the first incorrect step—not the final answer—and maps the error to a concept gap. Then it generates targeted practice for that specific weakness.
3
Retain
Practice until mastery, then review
Practice repeats until your mastery threshold is met. Then spaced repetition kicks in—reviews at 3 days, 3 weeks, and beyond.

Why Cognifiy is different

Built around diagnosis, not content delivery.

Step-level diagnosis

Finds where your method breaks—not just if the answer is wrong. Maps errors to specific concepts.

Saved mistake memory

Every error is logged. Recurring gaps get priority. The system learns what you struggle with.

Confidence gating

Low confidence? It regenerates or asks for clarity. No guessing. No hallucinated explanations.

Spaced repetition

After mastery, topics return at optimal intervals. Performance drops? Back to active practice.

Photo upload

Snap your handwritten work. Cognifiy reads it, parses the steps, and diagnoses in seconds.

Privacy-first

EXIF stripping, secure storage, no third-party sharing. Your work stays yours.

Security & privacy

Real protections. No marketing fluff.

Upload protection

Type validation, size limits, EXIF stripping, randomized file names, private storage paths.

Account security

Bcrypt password hashing, secure session handling, CSRF tokens, login rate limiting.

Data minimization

Store results, not raw noise. Old uploads auto-deleted. No unnecessary data collection.

Frequently asked questions

Common questions about Cognifiy.

How accurate is the mistake detection?
Cognifiy analyzes each step of your work, not just the final answer. It identifies the first incorrect step and maps it to specific concept gaps. Confidence scoring ensures explanations only appear when the system is certain.
What subjects does Cognifiy support?
Currently focused on mathematics: algebra, quadratics, factorization, fractions, graphing, and more. Additional subjects are planned based on user demand.
Is my data private?
Yes. Uploaded images are processed securely, EXIF data is stripped, and files are stored privately. We don't share your work or results with third parties. See our privacy policy for details.
How is this different from a tutor or chatbot?
Cognifiy is not conversational. It's a diagnostic engine that finds what you misunderstand, generates practice specifically for that gap, and tracks mastery over time. No random drilling or chat loops.
Can parents track progress?
Students control their accounts. Progress data (mastery levels, weak areas) is visible in the dashboard. Parental access features are planned for future releases.
What devices work with Cognifiy?
Cognifiy works on any modern web browser—desktop, tablet, or mobile. Upload photos directly from your phone camera or from saved files.
Is there a free tier?
Yes. Start free with core features. Premium tiers unlock additional practice volume, priority processing, and extended history.
How does spaced repetition work?
After you master a topic, Cognifiy schedules reviews at optimal intervals (3 days, 3 weeks, etc.). If performance drops, the topic returns to active practice automatically.
