AI Companion for Older Adults

What would a good chatbot say to your grandmother? A conversational AI that helps older adults reflect on their lives and record their stories, designed from developmental psychology rather than generic chatbot patterns.

01The challenge

Older adults are often an afterthought in AI product design. The project asked how a conversational agent could support emotional well-being and meaning-making late in life, not just answer questions.

02What I did

  1. 01

    Ground the design in theory

    Drew on Erikson’s concept of ego integrity and Validation Therapy to define what a good conversation should do for this audience.

  2. 02

    Design a three-stage dialogue

    Structured conversations as Validation, then Meaning, then Legacy, moving from emotional acceptance to meaning-making to recording personal memories.

  3. 03

    Test with real users

    Ran sessions with 30+ older adults and synthesized what worked, what confused people, and where the AI missed emotional cues.

  4. 04

    Propose how to measure it

    Wrote a research proposal pairing psychometric scales with linguistic sentiment analysis so outcomes could be evaluated, not assumed.
