Aeterna is an innovative digital legacy platform designed to help individuals preserve their life stories, memories, and voice as interactive digital archives. This tool is particularly beneficial for families looking to maintain their heritage and pass down personal narratives to future generations. Aeterna employs AI-guided interviews that prompt users with thoughtful questions, allowing them to record 5–10 minute voice notes. These recordings are then transcribed, analyzed for sentiment and themes, and organized into a searchable archive. Family members can engage with this archive by asking natural-language questions, receiving answers in the narrator's own voice. Key features include AI life interviews that guide users through their personal history, voice cloning technology that ensures the archive speaks in the user's tone, and a digital twin that allows family members to interact with an AI representation of the user. The platform also offers a private digital vault for securely storing photos and documents, family sharing capabilities, and animated memories that bring uploaded photos to life. Aeterna provides various pricing plans, including a free tier, making it accessible to users of all backgrounds, including those who may not be tech-savvy. The Aeterna Time Capsule, a one-time purchase, allows families to explore their digital legacy offline, ensuring that memories are preserved even without internet access.
