It's never too late to learn

TechX was made for people who think "technology is not for me". Tex is patient, the steps are small, and nobody is in a hurry. Just imagine:

Picture someone who has never used a computer. On day one they only ask AI for a soup recipe. A month later they write a polite letter to the bank with it, all by themselves.

Imagine a grandmother who wants nicer birthday photos for the family. One short lesson a day, and soon she makes her own cards with music.

Think of a shop owner who was afraid of "tech". Twenty minutes a day, and in four weeks the shop answers customers on WhatsApp with tidy price lists.

These are examples to picture, not real people.

Learning that feels like a game

Real skills, taught carefully, with a little fun to keep you going.

Stars for every lesson

Up to three stars each time, one for every right answer.

Days in a row

Do one short lesson a day and watch your count grow.

A badge every week

Finish a week and get a badge, plus an "I did it!" card to print for your family.

A certificate at the end

With your name and a code anyone can check. Share it with family on WhatsApp.

Gentle music, if you like

Soft music and happy sounds. Off until you turn them on.

Big text, your way

Make the letters bigger or the colours extra clear with one tap.

Questions

Tap a question to open the answer.

Do I need to know anything about computers?

No. If you can send a message on your phone, you can do TechX. Every lesson starts from the very beginning and uses everyday words.

Is the first week really free?

Yes. Start any course and do the whole first week for free. You only pay if you want to go on.

How much does it cost and how do I pay?

Courses cost from $7. A one-tool course is one payment; the big 12-week courses are paid monthly for three months. You pay the TechX office by cash, bank transfer or mobile money.

Do I need a computer?

No. A phone is enough for the lessons and the questions. A laptop makes the video editing and spreadsheet courses a little easier.

The writing is too small for me. What can I do?

Tap Text size at the top of the page and choose A+ or A++. You can also choose Extra clear colours. Every video has big captions, and a written transcript underneath with a Read aloud button.

Are the lessons videos?

Yes. Every lesson is a short, fun video with Tex, our friendly robot guide. He explains the idea in plain words, the words appear in big captions, and you can pause, go back, slow him down or watch again. Now and then he stops to ask you a question. After the video there is a small mission to try on your own phone or computer. Prefer reading? Open the transcript under the video.

How long is a lesson?

About 20 to 30 minutes, split into small steps. You can stop at any time and carry on later.

What do I get at the end?

A TechX certificate with your name and a code anyone can check. It is our own record of the work you did, not a university degree.

Is my information safe?

Yes. No advertising, no trackers, and we never sell your information or record your voice or face.
