Why these tools
No sign-up
No account, no plugin. Open the page and start. Every calculation happens in your browser — nothing is uploaded.
Built for media buyers
Metrics follow real buying practice: ROAS is judged against your gross-margin break-even, and UTM naming nudges your team toward one convention.
Growing set
The toolbox keeps expanding. Background removal, image upscaling and batch compression are already live on the Chinese site.
In-depth content is in Chinese
Our long-form articles, SOPs and templates on affiliate marketing, attribution, media buying and programmatic advertising are currently available in Chinese only. The tools are multilingual.
