SmartMatrix

Everyday apps, powered by AI, behind one sign-in

SmartMatrix is a suite of web apps for food, fitness, study and work — recipes with nutrition tracking, workout logs, flashcards and exams, notes, wikis and shared projects — with one account and an AI assistant that works across all of them.

  • One account. Sign in once; every app opens already signed in.
  • Your own AI. Connect an OpenAI, Anthropic or Perplexity key once and every app uses it — stored encrypted.
  • Phone and desktop. Install it like an app, in light or dark mode.

Your Google account in SmartMatrix

Sign in with Google (optional)

We use your Google name, email and account ID only to create your SmartMatrix account and sign you in.

Google Calendar (optional)

If you connect it from your profile, SmartNutrition adds the weekly meal plans you choose to export to your calendar as events, and updates or removes them when you change the plan. It never reads your other events, and you can disconnect at any time.
