Context completions
AI API allows businesses to privately integrate data shared by the user. By “sampling” user context—AKA taking a portion of data and transforming it in private AI—businesses can create adaptive experiences faster while maintaining user control and privacy.
Webhooks
Listen for changes in a user’s context across apps, allowing for your business to adapt to the user in real time. This allows you to take proactive AI-powered actions at exactly the right time, such as offering a new restaurant recommendation if a user's schedule opens up.

Activate our API with four lines of code.
After a user logs in with Crosshatch, their context can be translated by a language model to get a personalized AI response in any structured shape.
What your business gets:
- Conversion-optimized user onboarding flow
- Data integrations for spending, travel and more
- Managed privacy and access control
