About

Ethos

Features
Read full description

Ethos is a personal remembrance and reflection companion. It helps you preserve the voice, words, and wisdom of the people who matter most β€” and revisit the ideas that shape how you think. With Legacy, you create a profile of a loved one from their own writings, letters, and memories, then hold a conversation grounded in who they actually were. It's a new way to remember, grieve, and stay connected. With your personal reflection space, you build a private library from the sources that influence you β€” books, talks, notes, and videos β€” and explore them through thoughtful, grounded dialogue. Every response draws from your own chosen material, never generic answers. Features: - Legacy β€” preserve and revisit a loved one's words and character - Personal source library β€” books, notes, YouTube, and more - Grounded reflection β€” responses rooted in your own materials - Private by design β€” your archive belongs to you Ethos Plus Unlock voice cloning to hear a loved one's words in a voice that sounds like them, created from a short sample you provide and use with consent.
