How we review tools

Every tool we review is put through the same two questions, in the same order: does it fit the students it’s sold to, and is it any good. We report those two things separately, because they’re not the same thing — and most reviews quietly fold one into the other.

This page is the rubric, written down. It’s the same for every tool, including ones we like and ones we don’t.

Fit: the Four Mismatches Test

Fit is four questions. A tool has to clear all four; failing a single one means it was built for a different system and shipped to yours — product-export, however good the technology. We report fit as a count: how many of the four it clears. The full diagnostic, with worked examples, is in The Four Mismatches Test.

1. 1. Curriculum

   Does it teach the exam your students actually sit — SPM/KSSM, Cambridge IGCSE — or someone else's, like US Common Core?

2. 2. Language

   Does it work in the languages of the classroom — for a Malaysian room, Bahasa Melayu and English side by side — or English only?

3. 3. Price

   Can an ordinary family afford it without thinking about it — streaming-subscription money — or is it priced for a different economy? This is the one axis AI has already fixed.

4. 4. Infrastructure

   Does it run on a phone, on a patchy connection, without assuming always-on broadband and a personal laptop?

Quality: the score out of five

The score is about the tool itself, not its fit: how good the teaching is, how honest the product is about its own limits, how well it’s built and integrated, and whether there’s real evidence it works. A tool earns its number on those terms alone.

Keeping the two apart is the whole point. A tool can clear all four mismatches and still score in the middle because the teaching is thin. Another can be one of the best-built tutors in the world, score near the top, and still fit only one of the four for a Commonwealth buyer. Both are true at once, and a single star rating would hide it. So we give you the score and the fit, and let you weigh them for your own situation.

Independence, and how we make money

• No paid placement, ever. A tool cannot pay to be reviewed, to score higher, or to appear in a list. The rubric above is the only thing that moves a score.
• We exclude our own products. Addestra builds education software. Our own products are disclosed and left out of scoring — we don’t review our own work and call it independent.
• We’re plain about commission. Today we earn no commission from any tool we’ve reviewed. If that ever changes, the page will say so, and it still won’t change the score.

The wider standards behind all our writing — who authors it, how claims are checked, and how we handle corrections — are on the editorial standards page.
