Alethea is a research and development studio working at the intersection of generative AI and blockchain, and it now presents itself under the brand ALETHIA AI. Its core proposition is presence: interactive avatars that have a face, a voice, and a personality, and that see, hear, and respond in real time. Instead of static scripts or text chatbots, the platform is built for spoken, face-to-face sessions that feel like a live conversation with a person.
The product is organized around a few clear surfaces. Practice sessions let individuals and teams rehearse the conversations that matter in their field, with avatars trained on real-world scenarios and every session scored against explicit evaluation criteria. The Academy packages in-demand skills into cinematic lessons led by AI tutors that give spoken, real-time feedback. For organizations, real-time video agents combine the AI engine with a scalable intelligence framework so agentic workflows can handle operational needs at volume.
A third strand targets creators and brands: characters with a living presence that can turn fan interaction into a live, face-to-face exchange. Alethea also points to contributions to open source, and offers a direct route for teams that need API access. Because pricing is not published, commercial terms are arranged through a demo or call.
Let candidates practice their first interview against an avatar that asks real questions and scores answers against evaluation criteria.
Shape scenarios around business needs so teams can rehearse difficult conversations with an avatar before facing real customers.
Request API access to embed real-time video agents into products that need scalable, responsive intelligence.
Deploy characters with a living presence that talk, react, and respond to fans in real time.
