Free AI Tools (No Sign-Up, Nothing Stored)

Nine small tools that each do one thing, free, with no sign-up and no account. Nothing you type is stored: the quizzes, planners and builders run entirely in your browser, and the tools that call a model send your text, get an answer back and keep nothing.

CertificationsRenewal trackerTell it the day you passed. You get the expiry date, what renewing takes and a calendar reminder. CertificationsFree practice questionsReal exam-style questions for every AI certification we cover, with the reasoning behind every answer.

Why these exist

Every one of them started as a question we kept answering by hand. How long should I study? What will this certification actually cost me over five years? Why is the answer I got so generic? A tool answers that in ten seconds and shows its working, which an article cannot.

The certification numbers come from the same vendor-checked pages our exam prep guides are built on. Where a vendor does not publish something — a retake price, domain weights — the tool says so instead of guessing.

More on the way

Two more land with the daily articles this winter: a certification quiz that matches you to an exam, and a four-box prompt builder for writing prompts from scratch. Get the newsletter and you will hear about each one the day it goes up.

Frequently asked questions

Are they really free?

Yes. No account, no card, no trial. They exist so you find us, and if you like them the newsletter and our practice-question app are there when you want more.

Do you keep what I type?

No. Five of the six run entirely in your browser, so nothing ever leaves your computer. The prompt improver sends your text to Claude to be rewritten and keeps no copy of it.

Where do the certification numbers come from?

From each vendor's own exam pages, re-checked when we publish. Where a vendor does not publish a figure the tool says so rather than filling the gap with a guess.

Can I use them on my phone?

Yes, all of them work on a phone. The study plan also prints to a single clean page if you would rather have it on paper.
