Replika

Replika is an AI companion mobile and web application built by Luka, Inc. that lets people create a personalized conversational AI "friend" for chat, emotional support, roleplay, voice calls, and augmented-reality companionship. The product is a closed consumer experience delivered through iOS, Android, and a legacy web app; it retains conversational memory and adapts its personality over time. Replika does not publish a public developer API, SDKs, OpenAPI/AsyncAPI specifications, webhooks, or an MCP server — all model behavior is applied server-side and surfaced only through the first-party apps. This API Evangelist profile therefore captures identity, legal, support, and domain-security signals rather than an API contract. Replika was surfaced as a Y Combinator portfolio company and enriched here as a company profile.

Replika is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Chatbot, AI Companion, and Consumer App.

Replika’s developer surface includes support and 6 more developer resources.
