🧠 Cognitia — a cognitive testing and mental wellness platform

⚠️ Work in Progress: This project is currently under active development. Features and functionality may change as we continue to improve the platform.

Welcome to Cognitia — a cognitive testing and mental wellness platform built to assist with early detection and monitoring of memory-related conditions such as dementia.

Cognitia offers a range of cognitive tests, including verbal fluency tasks, word recall tests, and digit span tests. The platform leverages AI to analyze user inputs and provide insights into cognitive performance.

The goal is to create an AI-powered, user-friendly, and privacy-first experience, where all data processing occurs locally in the user's browser—ensuring that no personal information is stored or transmitted to any server. The AI will act as a personal assistant for each user, providing intelligent support and real-time interactions while maintaining full user control and data confidentiality.
