Conversations API · Available now

Put conversation practice inside your product.

Give your users a place to try the words before they need them. Bring a room, a responsive cast, a Coach and saved practice into the experience you already provide.

The practice experience

Choose. Practice. Reflect.
Try another approach.

Choose the conversation.

Start with one of 100 authored rooms in eight categories, or set up open practice. Choose from 52 AI characters, with up to five in a room.

Work with the whole room.

Participants respond in character and Coach helps with the next move. Each character's mood carries from turn to turn. With each turn, the API can report each character's expression, so your app can show faces that change as the conversation moves. Set the challenge, emotional heat and coaching lens. The cast speaks ten languages; Coach stays in English.

Return to what happened.

Replay the conversation, read the debrief and revisit observations tied to moments in the practice. Session continuity and saved preferences support the next visit.

Inside your product

Your experience.
The room, ready to connect.

Your application owns the screens and the user journey. We run the cast, the Coach and the saved practice on the same patent-pending foundation as Conversations.

You shape the practice.
The runtime supports it.

Conceptual integration. Your settings shape the practice; your application communicates directly with the API.

  1. Prepare a room.

    Choose the situation, participants and controls. Create the session from your server.

  2. Open it and send turns.

    Request the opening, then send the learner's turns. Responses stream back to your application.

  3. Read the saved practice.

    Bring playback, debrief and observations into your product when your users need them.
