If you're looking for something similar to HereAfter, Sensay could be an interesting alternative. It's geared toward generating personalized AI copies based on raw data and can be used in interactive experiences like entertainment, education and other areas. It doesn't have HereAfter's specific sharing abilities, but its AI avatars can capture personalities and offer continuous learning interactions, so it could be a new way to connect with family and friends.
Another option is Podcastle, an all-purpose web-based content creation studio. Podcastle has a wide range of tools, including a recording studio, simple audio and video editors and AI voices for generating content. It's geared more toward podcasting and video creation, but its collaborative abilities and high-quality output could be useful for creating personalized storytelling content.
If you're looking for something more focused on a legacy message, ContinYou offers a different approach. The app is for people who want to record and send personalized messages to loved ones at a future date. It includes features like future messaging, secure storage and AI-created characters for follow-up communications. It's a different take on leaving a legacy, since it lets you share messages and stories privately.
