// how it works

The platform + extension combo

Martex works in two parts: a web platform where you configure, visualize and export — and a Chrome extension that does the heavy lifting in the browser.

1
Install the extension
Free Chrome extension. Load directly in developer mode.
2
Connect to your account
Sign in from the extension and link it to your workspace and clients.
3
Run any tool
The extension runs in the background. Close the popup — it keeps working.
4
Export & share
Export to Google Sheets or CSV. Share reports instantly.
