Free trials, free tiers and free practice sites compared, so you know what you get before you pay.
There is no fully free, unlimited AI aptitude test solver. Most tools give a limited free allowance. ReasonEra includes 3 free trials with a free account; general AI assistants usually have a free tier with usage limits; some solvers offer a free trial; and free practice sites give fixed tests rather than AI explanations.
Free in this space is almost always limited by number of questions, usage per day, or features. Check three things before you start: how many questions you get, whether you need an account, and what you lose when the free allowance ends.
| Option | What is free | After the free part | Good to know |
|---|---|---|---|
| ReasonEra | 3 free trials with a free account | 14-Day Pass for 49 € (one-time), unlimited use across all supported tests | Built only for pre-employment tests; browser-based |
| General AI assistants such as ChatGPT | Typically a free tier with usage limits; check the provider | Paid plans; check the provider | Not specialised; you write the prompt and accuracy on visual puzzles varies |
| General AI test solvers such as Quizbot | A free trial with no card needed, per its site | Paid plans unlock higher usage; prices were not shown on the page we reviewed | Built for many subjects, not aptitude tests |
| Free practice sites such as Practice Reasoning Tests and Practice4Me | Free practice tests and sample questions | Not applicable, though some sites also sell paid libraries | Fixed questions, not an AI that explains your own questions |
| Free tiers of practice libraries (AssessmentDay, GraduatesFirst, Practice Aptitude Tests) | A free account or free tests, per their sites | Paid packs or plans | Good for sampling a library before you pay |
Details reflect each provider's public information as of 12 October 2026 and change often. See the comparison pages for each tool.
A free allowance is enough to judge a tool. A paid pass makes sense when you plan to practise many questions in a short window. ReasonEra's 14-Day Pass is one payment with unlimited use across all supported tests, so it suits a focused preparation sprint; a long-term library may suit a longer plan. See the roundup of practice tools.
Practice questions are fair game for study. A live assessment is governed by the employer's conditions, which you should read before you start.
Not an unlimited one. Most tools limit the number of free questions. ReasonEra includes 3 free trials with a free account, and general AI assistants usually offer a limited free tier.
Yes. A free ReasonEra account includes 3 free trials of the AI solver. After that, a 14-Day Pass costs 49 € with unlimited use across all supported tests.
A general assistant may offer a free tier with usage limits and can attempt aptitude questions from an image, but accuracy on visual puzzles varies by model and question. See our guide on whether ChatGPT can solve aptitude tests.
They do different jobs. Free sites give fixed practice questions; an AI solver explains the question you bring. Many candidates use both.
ReasonEra's free trials need a free account. Check the sign-up page for current requirements.
Use the free trials on the question types you find hardest, and compare the explanations with what you expected.
