Hacker News: nrkoka1https://news.ycombinator.com/user?id=nrkoka1Hacker News RSShttps://hnrss.org/hnrss v2.1.1Thu, 23 Jul 2026 04:09:37 +0000<![CDATA[Free browser-based tools – no account, no server uploads, all local]]>I built a collection of 27 free utility tools that run entirely in the browser. JSON formatter, Base64 encoder/decoder, AI content detector, password generator, loan amortization calculator, sleep cycle planner, Pomodoro timer, BMR calculator, and more.

Nothing is sent to a server — all processing happens locally in your browser. No account required, no sign-up, no cookies beyond analytics.

Also added a blog section with guides explaining how the tools work under the hood (how AI detectors work, what Base64 actually is, how loan amortization front-loads interest, etc.).

Happy to answer questions about how any of the tools are built.
