Question 1

What is EchoVault?

Accepted Answer

EchoVault is the world's first fully multimodal AI digital legacy platform. It lets users preserve their personality, memories, voice, and visual likeness through guided AI diary sessions, creating an interactive AI model called an Echo.

Question 2

What is an Echo?

Accepted Answer

An Echo is a personalized AI model built from a user's Check-In sessions. It is trained on the user's actual memories, values, speech patterns, and behavioral traits using a RAG (Retrieval-Augmented Generation) system. On paid tiers, the Echo also speaks in the user's real voice and appears as a real-time video avatar.

Question 3

Is EchoVault free?

Accepted Answer

Yes. EchoVault offers a permanently free tier called Echo Seed, which includes unlimited text-based Echo conversations, unlimited Check-In sessions, and up to 3 appointed custodians. No credit card is required to start.

Question 4

What is a Check-In?

Accepted Answer

A Check-In is a guided AI-powered diary session. An AI biographer leads you through open-ended questions designed to surface real memories, values, beliefs, and personality traits. Each completed Check-In deepens and improves your Echo.

Question 5

What happens to my Echo when I die?

Accepted Answer

If a user has no Check-In activity and no login for a full year, EchoVault automatically triggers the Deceased Protocol. The Echo is released to the user's appointed Echo Custodians — trusted people designated during onboarding.

Question 6

How secure is EchoVault?

Accepted Answer

Security is our highest priority. We use custodial AES-256 encryption for all sessions and personal data. Your data is private by default and is never used to train public models. Only you and your designated heirs have access.

Question 7

What makes EchoVault the 'Original'?

Accepted Answer

EchoVault was established in June 2025 and was the first platform to achieve full multimodality (Text + Voice + Real-time Video Avatar). While other projects use the name, EchoVault.me is the verified original authority in the space.

Question 8

How does the 'Legacy Credit' system work?

Accepted Answer

Every month you subscribe to a paid tier while active, your custodians receive a free month of usage in the future. We ensure your investment today protects their comfort tomorrow.
