Delphi

• Digital Mind Training - Trains on writing, podcasts, videos, and linked content to mirror communication style and domain expertise.
• Voice + Chat Experiences - Supports conversational experiences in both text and voice formats, including upgraded voice capabilities on higher tiers.
• Lead Capture + Recommendations - Collects contacts and supports recommended products/workflows for conversion-oriented journeys.
• Audience Operations - Includes contact import and CRM syncing on growth plans for cleaner pipeline handoff.
• Channel Deployment - Supports web embeds and broader distribution options, with premium channels like SMS/WhatsApp on top tier.
• Brand and Team Controls - Adds custom domains, visual branding kits, and collaborator seats as you move up tiers.
• Immortal API Access - API is currently Immortal-only (v3 base URL: https://api.delphi.ai), with documented endpoints for conversations, audience, tags, usage, and voice.
• Documented Rate Limits - API documentation currently lists 120 requests per 60 seconds per API key, which matters for high-volume product integrations.
• Permissions Safeguard - Checkout flow explicitly requires legal rights and written permission to create a mind, which is important for teams and agencies.

Delphi is increasingly positioned as a revenue and relationship layer, not only an AI chat widget. The product centers on turning your existing body of content into a conversational Digital Mind that can answer questions, capture leads, and route people toward offers or next steps.

For expert-led brands, this is useful when demand outpaces direct access. Instead of losing inbound messages or repeating the same explanations, Delphi can handle common questions, preserve style, and keep engagement active across voice and chat touchpoints.

The practical value is highest when you already have a clear point of view, repeatable offers, and a traffic source. Without those inputs, you can still deploy quickly, but conversion outcomes tend to lag because the mind has less high-quality context to work from.

Delphi now shows a meaningful pricing nuance: public list pricing and in-product checkout pricing can differ in presentation. Builder and Scaler are clearly still mid-market tiers, but the exact monthly and annual figures should be validated in your own checkout flow before budgeting.

The API remains a key differentiator for serious product teams, but it is currently tied to Immortal. If your roadmap includes custom app integration, usage tracking, or backend workflow orchestration, plan for an enterprise conversation early instead of assuming API access at lower tiers.

A strong purchase decision comes down to three questions: Do you have enough high-quality source content, do you have a conversion path after the conversation, and do you need native platform UX or API-level control. If those are clear, Delphi can move from experimentation to a real operating asset quickly.
