Method
How we test.
A verdict is only worth something if the tool was actually used. Here's the bar every post on this site has to clear.
- 01
Hands-on use
We sign up, open the tool and use it on real work. No rewriting the vendor's feature page.
- 02
Real builds
Agents, sites, content and automations — the same jobs we run for clients and our own brands.
- 03
Side by side
Comparisons put tools on the same task so differences show up in the output, not the marketing.
- 04
No paid placements
Rankings aren't for sale. If a tool is weak for a use case, the verdict says so.
