Techistra is a buying-guide site for consumer computing. Notebooks — by profession and by budget — smartphones, the parts inside a desktop, peripherals and the network they all sit on. Around three hundred guides and explainers, in English and Portuguese.
What we try to do
Most spec sheets tell you what a machine has. They rarely tell you what you need, which is a different question and the only one that matters when you are spending your own money. Our guides start from the work — legal research, 3D rendering, freelance writing, gaming — and reason back to the specification, saying out loud where the trade-offs are: what you give up for a lighter machine, where extra memory stops helping, when last year’s model is the better buy.
Who writes it
The site is maintained by the Techistra editorial team. Guides are researched and edited from manufacturer documentation, published reviews and benchmark data, and standards material. We do not publish under invented bylines and we do not claim lab facilities we do not have: we do not test machines ourselves, so where a claim depends on measurement we point you to the people who measured it. Nothing here is professional advice about a purchase your business depends on.
The spec adviser
Our one tool is the laptop spec adviser. Tell it what you do, how long you keep a machine and how much you carry it, and it returns the specification that fits, with the reasoning on every line and a guide to read next. It runs entirely in your browser; nothing you enter is sent anywhere or stored.
Languages
The site is written in English, with a growing set of guides in Portuguese. Use the EN/PT switch in the header. Where a guide has no translation yet, the switch takes you to the front page of the other language rather than to a machine translation.
How it pays for itself
Techistra is free to read, with no sign-up and no paywall. Advertising on the site is what pays for hosting and for the time spent testing. Advertising never decides what we cover or what we recommend.
Corrections
Hardware guidance dates faster than almost anything else, and we would rather fix a guide than defend it. Write to [email protected] and we will correct the article itself.
