Your services respond to each other

Each Conjoin service can trigger the next one. For example, when a user takes an action in your app, Conjoin can pass that event from Auth to Storage and on to Billing, with each service sending its result to the next.

Auth signs the user in with email, a social login, or SSO, then issues a session token for that user.

Storage saves the file in a container that the signed-in user owns.

AI indexes the content of the upload, so that your app can search it.

Relay receives the upload event and queues a background job for each service that processes the file.

Billing calculates the usage charges for that work and adds them to the customer's invoice.

One SDK for every Conjoin service

Your app calls every Conjoin service through one SDK, while your team manages all of them from one dashboard and pays for them on one invoice.
