Delphi AI

Delphi (Delphi AI, Inc.) is an "AI digital twin / Digital Mind" platform: experts, coaches, writers, creators, and public figures connect their existing books, podcasts, videos, Notion pages, and social media content to train a mind that can hold text, voice, and video conversations 24/7 while replicating the person's tone and knowledge. The official main site has migrated from the legacy delphi.ai domain to the brand home delphi.co.

Core capabilities

• Digital Mind creation: about 15 minutes in three steps - connect knowledge sources → complete a structured Q&A and record a 10-second audio sample for voice cloning → publish to multiple channels in one click
• Text / voice / video conversation: Voice Calling and Chat are supported, paid tiers upgrade to Pro Voice, and personalized video calls are available
• Knowledge source ingestion + citations: connect YouTube, podcasts, Notion, Google Drive, social media, and documents; answers come with cited sources
• Voice cloning: in partnership with ElevenLabs; a 10-second sample is enough to replicate a voice
• Omnichannel embeds and monetization: embed on websites/apps/SMS/WhatsApp/Slack/Zoom, with paid subscriptions and paid conversations
• Actions and guardrails: proactive actions (follow-ups, scheduling) launched in 2025; in strict mode the mind does not generate untrained content

How a Digital Mind works Ingested content becomes the knowledge base, paired with a proprietary mind model and RAG-style citation grounding, then voice cloning supplies the voice, and the mind converses outward by text, voice, and video; strict-mode guardrails ensure the mind "only says what you authorize."

Use cases Suited to experts, coaches, authors, creators, and celebrities who own a large library of finished content (books/podcasts/columns) and want to scale 1:1 Q&A and paid subscriptions; also to companies that want a "CEO/expert mind" to handle website support and leads. Those with thin content libraries will see a clear drop in fidelity.

Distinctive advantages Positioned between Coachvox (text only, from about $99/month) and Steno (done-for-you, from about $500/month); unlike the entertainment-focused Character.AI, it sells "a sellable mind of the expert themselves" rather than role-play.

Pricing highlights Freemium: Free $0 (1M Training Words), Builder $79/month, Scaler $299/month (the official site shows yearly-billing equivalents by default, basis=YEARLY), and Immortal custom; third parties cite monthly Builder $99 and Scaler $349-$399, without conversion.

Editorial assessment One of the category definers, with strong funding and expert endorsements and above-average maturity. But independent third-party review samples are severely lacking (the "Delphi" entries on G2/Capterra are polluted by the same-named Embarcadero IDE, and Product Hunt has only 3 reviews), so no overall conclusion is warranted; revenue-share and data-training statements also contradict each other. We recommend validating fidelity on Free/Builder first and locking in an annual plan only after confirming the terms in writing.
