About AlfennAI

AlfennAI is a free online tools platform: 37 calculators, converters, generators and utilities across 15 categories, with more added regularly.

Most tools run entirely in your browser -- your input is processed on your device and isn't sent to a server, so you can use them without creating an account or worrying about what happens to your data.

The site is built to be fast, clean, and genuinely useful, without the clutter and pop-ups common on many free tool sites. We keep advertising minimal and clearly separated from the tools themselves.
