PlainPC Health

Plain-English computer health check for non-technical users — one click tells you why your laptop is slow, what is eating battery, and what (if anything) you actually need to fix, without scary system jargon.

Target user

Non-technical adults whose computer feels slow and who do not know whether to panic

Features
  • One-click scan that returns a plain-English verdict ("Your laptop is slow because of background updates, not malware")
  • Battery, storage, and memory explanations in human terms with a 'what to do' button that actually does it
  • Weekly 'still fine?' check-in that reassures or warns without forcing the user to learn anything
  • Optional family-share so a tech-savvy relative can see the report remotely
Why now

Trending CLI monitor tutorials show ongoing public fascination with what happens under the hood of computers; most users cannot read that data and need it translated
