Attribute Finder

Which attributes of your marketing text correlate with performance?

Paste your marketing text (ads, emails, landing pages) and a performance metric (conversion rate, click rate, revenue, anything). Three tools each do one job:

1. Code measures what can be counted, like word count.
2. Jev by TypeSafe labels judgment calls, like problem vs solution framing.
3. Claude reads your text, never the results, and proposes attributes you didn't think to check. Then the stats run again.
