Aeterna: The D2C AI Digital Immortality & Heirloom Agency

In the 'grief tech' or legacy space, technical jargon kills conversions. Position the product exactly like StoryWorth or Ancestry.com—as a premium emotional preservation tool. Top-tier consumer brands sell the 'feeling' of connection, not the neural network architecture. Your ads must trigger nostalgia and the fear of losing family history, which has a drastically lower CPA than pitching 'AI avatars'.

The psychological friction of data collection is your biggest churn point. By using Typeform's conversational UI, you mimic a human biographer. Break the intake into 'chapters' sent over several days rather than one massive form. This 'drip-capture' method is heavily utilized by premium concierge services to maintain high completion rates without overwhelming the client.

A digital human is only as convincing as its memory retrieval. If you just dump raw text into a vector database, the AI will hallucinate or speak out of character. By forcing ChatGPT to extract an 'emotional_tone' and 'System Persona' alongside the memories, you ensure the final avatar responds with the correct empathy and linguistic quirks, avoiding the 'robotic customer service' feel.

Garbage in, garbage out. Video generation APIs struggle massively with low-resolution, grainy, or poorly lit source images, resulting in uncanny valley artifacts. Using Topaz to mathematically reconstruct facial details and normalize lighting ensures the downstream video avatar looks hyper-realistic rather than like a deepfaked ghost.

Never use the 'Instant Voice Clone' for a premium legacy product. The 'Professional Voice Clone' requires more audio and processing time, but it captures micro-expressions, breath patterns, and emotional resonance. Setting the stability slightly lower (around 0.45) prevents the voice from sounding like a monotonous audiobook narrator, giving it life-like conversational cadence.

**[EXTERNAL_TOOL_REQUIRED]** HeyGen (specifically their Interactive Avatar API) is required here. While tools like Kling or Pika are incredible for pre-rendered cinematic video, they cannot facilitate real-time, low-latency, two-way conversational video streaming. To achieve true 'digital immortality' where a grandchild can have a live video call with the avatar, HeyGen's WebRTC infrastructure is a non-negotiable requirement.

The 'I don't know' fallback is the most critical part of this prompt. If the RAG system hallucinates a memory about a family member that never happened, it instantly breaks the emotional illusion and causes distress. Constraining the LLM to strictly pivot to known memories preserves the integrity of the legacy.

Latency is the enemy of conversational AI. By using Make.com to orchestrate the backend, you can implement parallel processing or stream tokens directly to the video API. Ensure your HTTP modules are set to handle WebRTC handshakes if you are doing true real-time, or use asynchronous webhook responses to prevent timeout errors during generation.

The user interface must feel like a sacred space, not a SaaS dashboard. Using Replit AI to spin up a custom Next.js frontend allows you to completely white-label the experience. High-net-worth clients will not pay $5,000 to log into a generic third-party app; they are paying for a bespoke 'Family Vault' that feels entirely proprietary and secure.

This is a Model C [Collaborative Kickoff] deal-closer. You aren't just handing over a URL; you are delivering a 'Digital Will'. This document serves as a physical-feeling artifact that the creator can place alongside their actual estate planning documents. It solidifies the immense perceived value of the product and justifies the ongoing monthly hosting retainer.
