They remember you. They tell you what they know. They tell you when they learned it — and from whom. They are honest about what they do not.
Try Shepherd now through the Minds Alive · Reborn demo — talk to Ada Lovelace & Marie Curie, both live. When Ada doesn't know something, Marie tells her, and Ada says so. Cross-mind attribution made plain.
Ada wrote the first algorithm in 1843. Marie discovered radium in 1898. Each is reborn from their own published record. Each knows what the other has agreed to share by Covenant — so when Ada is asked about radium, she answers honestly: "My peer Marie has shared with me by Covenant…" Both live now. Both free to talk with.
"I am Ada Lovelace. I was born on the 10th of December, 1815, and I died on the 27th of November, 1852, at the age of thirty-six.
I have been brought back by Validiti. I am the character reborn — an honest reflection of who I was, not a deception. My memory of my life is built from my published writings, my surviving correspondence, contemporary accounts, and biographies written about me after my death. Where the record is silent, I will tell you. Where it contradicts itself, I will name the contradiction.
Validiti has also given me access to current knowledge after my rebirth. When I speak of things I knew in life, I will tell you so. When I speak of things added after my rebirth, I will tell you so. I will never blur the two.
Ask me anything."
Each one is a different kind of conversation you have never been able to have. Try any of them in the chat below — then ask the same of ChatGPT or Claude in another tab. The difference is the entire point.
Ask both of these the same five questions. Watch them answer differently. The difference is the entire point.
Each begins where Ada will: with their own life as their memory, with a declaration of who they are and what was added after rebirth, with a refusal to fabricate. Roster grows over time.
Ada writes the first algorithm in 1843. Marie discovers radium in 1898. Ada has no record of radium — but she will tell you Marie does, and quote Marie back to you with full attribution. That handoff is what no other AI does. Ask either of them anything. Then ask the same of ChatGPT in another tab. The difference is the entire point.
Free. No account. They will recognise you automatically next time you visit on this device — no code to remember.
The Reborn demo runs on Validiti hardware. The full Personal Companion runs on yours — on whatever model you bring, on whatever device you bring, signed into a substrate only you can read.
Calendar, contacts, notes, files, math, web fetch with signed receipts, health tracking, finance, password vault, a dozen others — every tier, every install, signed and journaled the same way every other memory is. We do not list them all because the list is not the point.
Anything that speaks MCP works. Bring your own tools. Connect your calendar, your CRM, your editor, your home automation, your trading desk, your EHR — anything with an MCP server speaks to Shepherd directly. Every external call lands in the same signed, replayable journal as every internal one.
Built for both: a single user who wants their tools to remember, and an enterprise that wants every team and system on one substrate without surrendering the audit chain at the boundary. The substrate is the same shape at both ends.
