Delphi: Turn Your Expertise Into a Digital Mind

Delphi lets experts, creators, coaches, and public figures build an interactive AI version of themselves — what the company calls a Digital Mind. You connect your existing body of work (books, articles, podcasts, YouTube videos, courses, websites, documents) and Delphi builds a conversational clone that can answer questions on your behalf, in your voice, 24 hours a day. Your audience gets a one-on-one conversation; you get scale without giving up your calendar.

Where generic chatbots improvise, Delphi grounds every response in your actual material and cites the source content it drew from, so the clone stays on-message and factually tied to what you have actually said or written. Setup takes roughly 15 minutes to get a first working Mind, and the Mind keeps evolving as you feed it new content.

Key Features

• Digital Mind builder — connect documents, websites, social content, YouTube, and podcasts; a first working Mind takes about 15 minutes
• Grounded, cited answers — responses reference the source material they were drawn from to keep the clone authentic
• Voice calling — record a short audio sample and your Mind can speak with callers in a cloned version of your voice
• 40+ languages — your audience can converse with your Mind in their own language
• Audience CRM tools — contact collection, CRM syncing, custom workflows, and product recommendations on paid tiers
• Flexible deployment — website embeds, Slack integration, custom domains, and SMS/WhatsApp and API access at higher tiers

Ideal Use Case

Delphi fits creators, coaches, authors, speakers, and investors whose audiences want more access than one person can physically provide. A course creator can let students ask unlimited questions of their Mind, a health expert can field recurring questions at scale, and an executive can turn years of writing into an always-available mentorship channel — with monetization options on the top tier.

How Delphi differentiates

Delphi raised a $16M Series A led by Sequoia Capital in 2025, with participation from Anthropic's Anthology Fund (with Menlo Ventures) and founders of companies like Zoom and YouTube. Named users of the platform include Tiago Forte (Forte Labs), Dr. Mark Hyman, and HubSpot co-founder Brian Halligan — a notably credible roster for the digital-clone category.

FAQ

Is Delphi free to use? Yes, there is a free tier that includes your first Digital Mind with chat and voice calling and 1M training words. The Builder plan is $79/month (billed annually) and Scaler is $299/month; the Immortal tier is custom-priced.

How does Delphi keep my clone accurate? Answers are grounded in the content you upload and cite the source material, rather than being free-form model output.

Can my Digital Mind sound like me? Yes — Delphi can clone your voice from a short recorded sample so the Mind can hold spoken conversations.

Who is Delphi built for? Experts, consultants, coaches, authors, speakers, investors, and public figures who want to scale one-on-one interaction with their audience.

tl;dr

Delphi turns your accumulated content into a cited, voice-enabled AI version of you. Backed by Sequoia and used by names like Tiago Forte and Mark Hyman, it is the most established platform in the digital-clone space, with a genuine free tier to start.
