Memodi

Memodi is a voice-first AI memory companion that helps people with cognitive decline recall routines, people, places, and objects through calm, personalized support.

Comment

Memodi was inspired by something deeply personal: both Atishay’s grandpa and Gagan’s grandpa have dementia. Seeing how memory loss affects not only the person experiencing it, but also the family members and caregivers around them, pushed us to build something that feels more human than a normal chatbot.

Memodi is a voice-first AI memory companion for people with cognitive decline. It helps patients ask questions naturally and receive calm, personalized answers grounded in real memories, routines, family details, and preferences entered by caregivers. Instead of giving generic responses, Memodi tries to answer like someone who truly knows the patient.

We built Memodi with a caregiver memory bank, a patient voice companion, emotion monitoring, and an object-finding tool that can help locate important items from a photo. We learned a lot about designing AI for vulnerable users, including the importance of gentle language, accessibility, privacy, and not inventing facts when memory context is missing.

One of the biggest challenges was connecting many moving parts into one experience: AI reasoning, memory retrieval, voice input, local text-to-speech, caregiver tools, and real-time object tracking. We also had to think carefully about how to make the interface simple and comforting for patients while still useful for caregivers.
