Companion Builder
Design, build, and launch AI companion apps in minutes
Request access to our beta. We're onboarding a select group of teams crafting open-ended relational conversation experiences.
A new type of voice platform
Companion Builder is the only voice AI platform purpose-built to enable open-ended conversations.
- Relational long-term conversations
Scaffolding to build conversational agents that can build and maintain human-like relationships over time.
- Open-ended conversation design
Tools and systems that are purpose-built for open-ended conversations as opposed to task-oriented conversations.
Why adding open-ended conversations changes your product and how we design realistic companions.
Elements
- Low-latency infra
Drop-in voice and text back-end you can integrate immediately. APIs that immediately handle conversation generation with low latency.
- Conversation analysis
Purpose-built conversation design tools to surface the most insightful dialogues, trace breakdowns, and fix them strategically.
- Memory retrieval
A dynamic memory system that recalls the right memories relevant to the conversation's immediate context, with ability to handle conversation lengths that context windows can't.
- Adaptive modes and prompts
Real-time understanding of conversation state and topic to shift mode, tone, and context so you can provide an engaging experience for multiple situations with multiple prompt designs.
- Prompt versioning & A/B testing (coming soon)
Iterate safely. Compare versions, test in isolation or on production, and learn fast.
- Instant testing
Update your companion and talk to it immediately. See how changes affect the live conversation with no rebuilds and no waiting.
Examples
- Friendly companion
An empathetic conversational partner that builds real rapport over time, deepening personal relationships with every exchange.
- Language practice companion
Free-flowing practice sessions that recall past dialogues and shift tone to keep learners engaged in natural conversation.
- Learning companion
Open-ended tutoring that references earlier lessons and steers engaging dialogues to strengthen long-term recall.
- Financial companion
Always-on guidance that remembers goals, surfaces insights, and adapts its tone so advice feels like a trusted conversation.
