About Mantlin

Last updated 11 September 2026.

Mantlin is a practice platform for the Life in the UK test. It gives you free practice tests with saved progress and honest feedback on where you are strong and where you need more work. A one off Pass Pack with the deeper study tools comes later, and it is a single payment rather than a subscription. It is built to be calm, clear and free of the clutter and dark patterns common in this space.

Why this exists

I built Mantlin while my partner and I were preparing for our own Life in the UK tests. The practising itself was fine. Everything around it was worse than it needed to be. Cluttered, full of adverts, and vague about whether what it was teaching you was actually right.

I build software and automation for a living, mostly internal tools and AI where it genuinely helps rather than where it sells. So this was squarely in my wheelhouse, and it was hard to keep noticing the gap without doing something about it.

Mantlin started as a better way to practise for one exam. The intention is for it to grow into something broader.

I am Vinicius Dos Anjos Coelho, the sole developer. It is a passion project alongside my other work, and you are welcome to follow along on LinkedIn (opens in a new tab).

We are independent

The official test can only be booked and taken through GOV.UK. We use the name “Life in the UK test” only to describe what our practice material helps you prepare for.
