Delphi

Delphi is an AI platform for building "Digital Minds" — hyper-realistic AI clones trained exclusively on a person's own content (podcasts, videos, blogs, long-form writing, live feeds) that match how they speak, write, and think. Audiences can call, text, or video-chat a clone 24/7 for Q&A, coaching, mentorship, and engagement, with omnichannel reach across websites, SMS, Telegram, Slack, and learning platforms like Kajabi and Thinkific. Delphi's v3 REST API (Immortal plan) lets developers embed a Digital Mind directly in their own app: create conversations, stream text and voice responses, manage the audience and its contextual memory, organize contacts with tags, search the clone's knowledge base for RAG, track per-user usage, and receive events via signed webhooks. Delphi is backed by Menlo Ventures.

Delphi publishes 1 API on the APIs.io network. Tagged areas include Company, Artificial Intelligence, AI Clones, Digital Minds, and Conversational AI.

The Delphi catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Delphi’s developer surface includes documentation, API reference, getting-started guide, authentication, changelog, support, engineering blog, and 21 more developer resources.
