The problem or experience
Most advice about focus and decisions is either vague or buried in videos. Cognition OS turns it into lessons, habits and tools you try in the browser.
Who it's for
Students and anyone who wants to think more clearly.
My contribution
It is my project, built with React and TypeScript. The source is private.
What works today
- 26 lessons, 17 habits and 6 thinking tools, as listed on the site.
- Progress stays in your browser; no sign-up is needed for the free part.
- A Brain Power calculator you can try on the home page.
Limitations
- The Brain Power numbers are the site's own cautious estimates, not medical advice.
- Most lessons need a paid license.
- The source is private.
