Why we built it
Modern AI assistants learn you slowly, then keep that memory behind their own walls. Use more than one — Claude for writing, ChatGPT for research, a local model for sensitive work — and you end up with several parallel memories, none of which sees the whole person. Switch models and the context doesn't travel. Change of terms, and your accumulated memory is held hostage.
We thought the memory and the character of your AI should sit with the person, not the vendor. So we built a memory layer you actually hold — a signed, local-first file that any AI can read, present across every model and every device at once.
The founder
aiperson is led by Humphrey Theodore K. Ng'ambi (TK) — a systems architect and cybersecurity engineer based across Johannesburg, South Africa and Lusaka, Zambia. TK has run a working prototype of this memory layer on himself for over a year: git-backed persona, sync across surfaces, the whole thing refined under daily multi-model use. aiperson is the productisation of a system he already lives in — not vapourware.
How we're built
aiperson is built on the .person Protocol — an open standard for memory, identity, and rights. The Protocol is held as a public good by the .person Foundation, a US 501(c)(3) non-profit whose charter contains an irrevocable perpetuity clause forbidding conversion to a for-profit. dotPerson PBC, the company you are buying from, is a separate commercial entity — a US Public Benefit Corporation — that builds and operates products on the open Protocol under a revocable-for-cause licence from the Foundation.
We drew that boundary in legal documents before raising any commercial capital, precisely because the question — "what stops you converting to a for-profit later?" — matters. The architecture is designed to be substrate-neutral and is fully published: anyone can read it, verify it, or build a competing implementation on the same Protocol. Our moat is being the best implementation, not the only one. The full corpus is open at dotperson.org.
What aiperson is not
Not a model.
aiperson doesn't host or run LLMs. It's the memory and character that the models you already use read from and write to.
Not a chat app.
The chat happens in your chosen AI; aiperson is the silent, persistent layer beneath it.
Not a social network.
The relationships it models enrich your AI's understanding of you — they're not a graph for others to see.
Not lock-in.
Open format, exportable any time, self-hostable. You can leave with everything.
Cultivate one AI. Keep it yours.
