How we evaluate

Data sources

We aggregate and cross-reference data from Wikipedia, Hacker News community discussion, official vendor pricing pages, and public app-store data. All pricing verified within 72 hours. No vendor pays for placement or ranking position.

Update frequency

All pricing is verified within 72 hours. Our system re-checks every tracked tool's pricing, features, and review sources on a fixed schedule. When something changes — pricing, features, ownership — we update and note it on the relevant pages.

Scoring

Where we score, we use objective, reproducible metrics — never one AI judging another. Salman Khan reviews a sample of outputs against a fixed rubric. Human verification is the one input no model can replicate.

Affiliate disclosure

This site contains affiliate links. We earn a commission if you purchase through our links at no extra cost to you.

Independence

Rankings are determined by verified data only. Commission rates are never a ranking factor. Tools with no affiliate programme are ranked exactly the same as tools that pay well.
