Your iPhone, for any assistant.

Other apps talk. Sintax lets your assistant use your iPhone.

Works with ChatGPT, Claude, Grok, Gemini, and other popular assistants.

Weeknight suppers

Plan the week. Each night → Calendar. What to buy → Reminders list Groceries.

Plan suppers for this week and put each night on my calendar. Make a Reminders list called Groceries with what I need to buy.

Trigger any shortcut from your assistant on your iPhone.

I’m on my way, Home ETA, Leave By, Add to Groceries, DND for a meeting, battery-dying text, flashlight, directions home, send the latest photo, play a playlist.

Run my shortcut I’m on my way.

You choose the names in Settings.
