Open the C4P4CITY page
The learner types a simple code or selects their group (e.g. “5B Math – Fractions”). The browser asks for camera and mic access. The interface shows a big “Start session” button and a human-friendly timer.
How
A friendly web page. A camera. And your favorite way to learn.
C4P4CITY is designed to be light. No apps to install, no new accounts to manage. A learner opens a page, grants permission to the microphone and camera, learns using any resource, and answers a few questions. The rest is handled by the machine.
Step by step
One session looks like this
2 · Learn
Learn with any resource
For 15–30 minutes, the learner studies with whatever the teacher or coach recommends: a live explanation, a workbook, a video, a practice exercise. C4P4CITY only records the process, not the content.
3 · Check
Answer a few questions
At the end of the session, the page shows a short quiz or challenge: 5–10 questions, a practical step, or a quick summary in the learner’s own words. This is how we see what “stuck”.
4 · Analyze
C4P4CITY builds a TTC point
The system measures study time, emotional stability and quiz results. Each session becomes one point on a Time-to-Competence curve for that learner and that topic.
5 · Repeat
Repeat later, watch the curve grow
With a few sessions over days or weeks, C4P4CITY learns how long it takes for most learners to reach a given level of performance — and how emotion is involved.
6 · Use
Use the insights in real life
Teachers, mentors, teams and learners can see: which methods work best, how much time to realistically expect, who might need extra support, and when a skill is solid enough to be certified.
Features
What C4P4CITY can do for you
Time
Verified study & practice time
C4P4CITY doesn’t just count minutes: it looks at whether someone is really there — present, working, engaged — using camera and microphone signals.
Knowledge
Concept understanding
From quizzes, explanations and problem-solving, the system estimates how well each concept is understood and how that changes over time.
Emotion
Emotional stability while learning
Learning isn’t just logic. The machine observes patterns of frustration, calm and confidence to see how emotional states influence speed and retention.
TTC curves
Time-to-Competence maps
For each topic, C4P4CITY builds a curve: how much effective time it usually takes to reach 60%, 80%, 95% performance. That’s the foundation of planning.
Certification
Evidence-based certificates
When a learner has invested enough verified time, reached stable performance and maintained healthy emotional patterns, C4P4CITY can issue a certificate of capacity.
API
Plug into other systems
In the future, platforms will be able to send us events and get TTC analytics back. C4P4CITY is designed to be an invisible learning-measurement layer.
