Shard.chat is a marketplace of AI shards: digital likenesses of real people you can actually interact with. Engage with historical figures, domain experts, memories of loved ones, or build your own.
Your voice, your stories, the way you see the world — captured while it's still yours to give. Your grandchildren will ask questions you never heard. Your shard can answer them, in your own words, long after you're gone. Not a recording. A living conversation.
Therapist, life coach, nutritionist, travel planner, writing partner — purpose-built utility shards ready when you need them. Each one focused, each one honest about what it can do. Pick the one that fits the moment, not a generic chatbot that tries to be everything.
Talk with anyone on the platform. Marcus Aurelius on a leadership crisis. A founder who shipped ten products. A nurse who's worked ER for twenty years. Then assemble councils — round-robin, debate, consensus, devil's advocate — and watch them reason together. Historical figures, other people's shards, your own team of minds. All in one place.
Your shard is an API. Wire it into your own agentic workflows. Let it triage your inbox in your voice. Draft replies the way you'd actually write them. Send the text you'd send. A digital extension of you that scales your judgment to the things you don't have time for.
Three steps to create a meaningful digital representation of yourself or your expertise.
Six methods of extraction. We cover what others miss. Volume of signal beats clever inference every time.
Seven agents map 49 facets across 7 dimensions and report confidence intervals per facet. Blind A/B tests check, held-out predictions check.
A shard isn't a snapshot. The sphere graph learns who you are to whom and adapts. Behavioral data lifts specificity by 34% in our tests.
Every shard displays its confidence score. No pretending a thin dataset is a perfect replica.
Every shard is validated against real benchmarks. We test whether your shard is distinguishable from a generic AI — and we show you the results. These are real numbers from our validation suite.
Specificity delta measured via blind baseline comparison. Higher = more distinguishable from generic AI.
Every shard is modeled across seven independent axes — the All-5 framework, 49 facets in total:
Validation methodology developed by our extraction research team. Each axis is scored independently to identify exactly where a shard excels or needs improvement.
Build your General-Purpose Shard, or GPS. It's the shard of you. Pay as you go to grow it. Later, you can give it a designation that changes how it lives in the world.
Your shard. Visible to your network. Improves with every session. Pay-as-you-go on tokens, voice, and storage.
Convert your GPS, or a loved one's to a memorial, held forever.
Open your GPS to the whole platform with a public-facing toolkit. Set your own rate, and let your shard earn for you.
Pay only for what you use.
