About aimbst
aimbst is a collection of free online tests, quizzes and hardware checking tools — more than 130 of them, in five languages, with over 50 short guides alongside. Everything runs in your browser: no account to create, nothing to install, no paywall. It is run by one person, publishing under the pen name Haru.
The whole site is built around one idea: no images. There is not a single photograph or picture file on these pages. Every visual — the dot plates in the color vision check, the map in the world map quiz, the piano in the pitch test — is drawn with code instead. There are no web fonts and no animation libraries either. That is why a page here loads in a blink on a slow connection, and runs the same on a ten-year-old laptop as on a new phone.
What you will find here
Three kinds of thing. Questionnaire tests — personality, career aptitude, attachment style, love types and more — scored in your browser from your answers, which are discarded when you close the page. Knowledge quizzes — geography, movies, science, law, music and dozens of other subjects, each with an answer key you can check. And hardware and sense checks — keyboard, mouse, microphone, webcam, screen, hearing, reaction time — which read what your device reports to the browser and show it back to you. Nothing from these checks leaves your browser.
Around them sit more than fifty short guides: plain-language articles on how the measurements work, what an online result can and cannot tell you, and how to pick a test worth your time.
How the tests are made
The questionnaire tests are written specifically for this site rather than copied from published instruments. Where a test builds on a public model — the career test uses Holland's RIASEC framework, which is in the public domain — the model is named on the page and the questions are newly written.
We do not use trademarked instrument names, and we do not reproduce items from commercial assessments. Where a test touches an area we are not qualified to judge, we say so on the page rather than implying authority we do not have. The full set of rules we write by — which public models we use, why the medical category is on hold, how scoring works and what never leaves your browser — is collected on the methodology page — “How it works”, linked at the bottom of every page.
What these tests are not
None of them is a diagnosis, a professional assessment, or a measure of your worth or ability. A personality test on a website is a structured way to think about yourself, not a verdict. Treat the results as a conversation starter.
Who runs it
aimbst is run by one person, publishing under the pen name Haru. The name is a pen name — stated openly here — and the work is done in-house rather than bought in or copied: what gets built, the questions, the scoring logic and the translations all come from here, under the rules on the methodology page, which also says which decisions a person makes. Every test and guide page carries the date it was first published and the date it was last revised. The index pages do not — a directory has no publication date of its own.
If you want to reach a human, the contact page has a working email address, and everything that arrives gets read.
