Each tool does one job and needs no account. Five use an AI model to read what you paste: the job scam checker, the AI summarizer, the email reply generator, the prompt enhancer and the quiz generator. Four run entirely in your browser: the which-AI-should-I-use quiz, the study plan generator, the certification cost calculator and the renewal tracker. The tenth is our free practice questions for AI certification exams.
No sign-up, nothing stored: what that means
- No account. Every tool works without signing up. A few longer runs, such as a 15-question quiz or a very long summary, ask for an email address instead, which also signs you up for the newsletter.
- Nothing you type is kept. The AI tools send your text to the model and the answer comes straight back to you; we do not store or log it. The browser tools never send what you type to us at all.
- Fair daily limits. Each AI run costs us money, so those tools allow a few free runs per person a day.
Why these exist
Every one of them started as a question we kept answering by hand. Is this job offer real? How long should I study? What will this certification cost me over five years? A tool answers that in 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, such as a retake price or domain weights, the tool says so instead of guessing.
Looking for a free ChatGPT, Claude or Gemini?
These tools each do a single job. For a general-purpose AI assistant, do you need to pay for AI? helps you decide whether a free plan is enough, and ChatGPT vs Claude vs Gemini compares the big three.
More on the way
Two more arrive 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 these AI tools really free?
Yes. No account, no card and no trial. The AI-powered tools allow a few free runs per person a day, and a couple of longer options ask for an email address.
Do I need to sign up?
No. Every tool works without an account. A few longer runs, like a 15-question quiz or a summary of a very long document, ask for an email address instead.
Do you keep what I type?
No. The four browser tools work out their answers on your device. The five AI-powered tools send your text to an AI model to produce the answer, and we do not store or log it.
Which AI model do the tools use?
The AI-powered tools use Claude, from Anthropic. The browser tools do not use an AI model at all; they run on fixed rules and our own vendor-checked exam data.
Where do the certification numbers come from?
From each vendor's own exam pages, checked when we publish. Where a vendor does not publish a figure, the tool says so rather than guessing.
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.
