About YakRoo

อยากรู้ (YAKROO) is the writing arm of Cosmixon, run by a developer who builds and operates the systems described here — a retail POS, a clinic system, personal finance tooling, and day-to-day work with AI agents.

What gets written here

• AI & Tech — Agents, models, and what it takes to make them actually work
• Money & Business — Shops, investing, and building something people pay for
• Health & Longevity — The body, sleep, and staying around longer
• General — Things that fit no category but are worth knowing

House rules

• First-hand only. Nothing here is a translated repost. When someone else's work is used, it is credited and linked.
• Unknowns are labelled. If something has not been tested here, the article says so instead of sounding confident.
• Numbers are checkable. Any measurement comes with how it was measured and under what conditions.
• Corrections stay visible. Articles revised on a material point carry the revision date.

On health content

Health articles are general education backed by the sources listed at the end of each piece. They are not medical advice and do not replace a consultation.

On advertising

This site may show ads so it can stay free to read. Ads never influence what gets written, and paid reviews are not accepted without disclosure. Any article with a conflict of interest says so at the top.
