Seelique

AI Companion & Family Memory Platform

Seelique helps families stay close across distance and time. Relatives build a shared memory vault — photos, voices, stories — and an AI companion brings it to life for elderly family members: speaking in a familiar cloned voice, in the user's own language, drawing only on family-approved memories. From voice avatars to personal video avatars, with wellbeing insights for the family. Multilingual by design: family members contribute in their languages, the user listens in their own. Developed with our venture partner. Launch planned 2026/27.
