Share from Cali

Hit share in the desktop app and a unique cali.run link is automatically generated for your calculation.

Send it anywhere

Copy the link and share it however you want - Slack, email, text, or carrier pigeon.

Collaborate live

Recipients get their own interactive instance. They can tweak values, explore scenarios, and share their version back.

Open in desktop

If they have Cali installed, one click opens the calculation in their desktop app for a native experience.

Synced by default. Flexible by design.

Cali saves your files to iCloud automatically - access them from any Mac. Prefer a different location? Change the default folder, disable auto-save, or go fully manual. Your files, your rules.
