StillHere

A trained-on-their-texts keepsake app that helps grieving families draft a 'letter from' a deceased loved one on anniversaries and milestones

Target user

Bereaved adult children and spouses seeking comfort on anniversaries

Features
  • Family-member onboarding flow that lets a loved one (or a posthumous family admin with consent) feed years of their messages into a private voice model
  • Anniversary and milestone trigger: 'Dad would have written you today' drafts a short, in-style letter that the family can read, print, or save
  • Guardrails: no factual claims, no impersonation outside family, no sharing beyond named recipients — all processing on-device
  • Optional therapist-share mode so grief counselors can co-read drafts in session as a therapeutic aid
Why now

The same on-device style-clone capability is directly applicable to legacy/grief use; no mainstream product has packaged this for non-engineer families, and consumer AI-tools trend line is finally warm.

Demand

Crowded adjacent space — AfterLive, Lumish, Dead Talks, RightBack, Mourning.AI all offer chatbot/voice-clone grief experiences; the 'letter on anniversaries' framing is partially differentiated but easy for any of these incumbents to add.AI Grief Chatbot — Talk to a Loved One Who Has Passed | AfterLiveLumish - AI Companion for Grief SupportClone the Voices of Your Deceased Loved Ones with AI - Right Back

Monetization
4/10

No published pricing found in competitors I surfaced; many grief-AI sites (Dead Talks, Mourning.AI) appear free-tier, suggesting an unsettled willingness-to-pay and a category where users may not sustain subscriptions.Talk to Dead Loved Ones Online Free — Dead Talks AI AppSupport for Grief and Loss - Mourning.AI

Longevity
5/10

Category growing (12.97% CAGR per market reports) but faces significant ethical, regulatory and mental-health headwinds — clinicians warn griefbots can cause harm and 'losing the bot = losing the person twice'.AI Chatbots Let People Keep Dead Loved Ones Alive.

Feasibility
5/10

Technical core (small on-device Transformer on personal text corpora) is proven by the cited GitHub-trending project; remaining work is largely product/UX, data-ingestion plumbing, consent flows, and content moderation — non-trivial but no fundamental blockers.AI Afterlife as Digital Legacy: Perceptions, Expectations, and Concerns
