THE PROBLEM
What we keep hearing
-
You charge a monthly care fee, but your client never sees anything for it
-
Report tools are WordPress plugins that don't work for your Webflow, Framer or Next.js builds
-
You want to sell retainers, but "what do I deliver every month?" keeps you from pitching them
HOW IT WORKS
One minute of setup, then nothing else
- 01
Add a URL
No plugin, no embed, nothing to install on the site.
- 02
Kotori checks daily

A letter goes out monthly
To your client, in your name. You write nothing.

THE LETTER
A letter your client will actually read
Monitoring graphs mean nothing to your clients. Kotori turns real measurements into a plain-language letter and sends it in your name, automatically. Every number is measured, and there's nothing for you to write or send.
✕ A monitoring dashboard your client won't read
