Aqil Abbas Khan
Founder & Editor of ToolsNexus
Aqil Abbas Khan founded ToolsNexus and runs it as its editor: deciding which tools and calculators get built, setting the standards they have to meet, and signing off on every one before it goes live.
For the finance, tax, and legal pages, that sign-off covers the formula each calculator implements, the official data it relies on (IRS tax brackets, contribution limits, published state rates and guidelines), and the plain-language methodology notes shown on each page. Figures are checked against two independent sources before they ship — where the sources disagree, the tool waits rather than guessing. Where a calculator makes a simplifying assumption, its methodology section says so explicitly rather than hiding it.
The same principle runs through the rest of the site: file tools process everything inside your browser, so nothing is uploaded, and every calculator shows its sources and a last-updated date that is refreshed when the underlying official data changes.
Everything here is an educational tool, not personalized financial, tax, or legal advice — for decisions that depend on your specific situation, talk to a qualified professional who can see the whole picture.

On the 2 health calculators he checks the formula and the published cut-offs it uses, and the pages say so — he is not a clinician. Other tools on the site are maintained by ToolsNexusand labelled that way.
How review works
- Each figure comes from the official source that sets it and is checked against a second independent source; when they disagree, the figure waits.
- Each calculator's math has automated tests that run on every change.
- Pages are drafted with AI assistance (Anthropic's Claude); he approves every change before it goes live.
The full process is on how we verify.
