AI memory, answered.

aiperson is an AI memory layer: a portable, local-first store of who you are and how your AI behaves. The persona you've shaped — voice, values, conventions, refusals, relational history — lives in a signed file you own and is projected into every AI you use, from ChatGPT and Claude to local models. Cultivate one AI, keep it yours.

An AI memory layer is a single, portable store of your context and your AI's character that any assistant can read, instead of each app keeping a separate, vendor-locked memory. It holds your memory once, in a place you control, and lets every AI read from it.

It is free while we build toward our first 100 Founding Members. No credit card required. Sign in with GitHub, run two commands, and your existing AI tools gain a shared memory in under ten minutes.

Thirteen editors and CLIs over MCP — Claude Code, Cursor, VS Code, GitHub Copilot, Windsurf, Zed, JetBrains AI, Antigravity, Augment, Continue.dev, Cline, Aider and Gemini CLI — plus 21 cloud chat surfaces via the browser extension, including ChatGPT, Claude, Gemini, Microsoft Copilot, Grok, Meta AI, Perplexity, Mistral, and the Chinese frontier (Kimi, DeepSeek, Qwen and more).

Vendor memory lives on the vendor's servers, in their format, and works only in their app. The March-2026 import features let you copy it out once, lossily. aiperson keeps one persona you hold, signed by your own key, present across every AI at the same time — not a one-time copy. You can export it any time and self-host it.

Yes — that's the whole point. Cultivate an AI under Claude over a week, then point a local Llama (or ChatGPT, or Gemini) at the same persona file. It greets you the same way, holds the same refusals, and remembers what you were working on. The persona moves intact because it's a file you own, not a setting inside someone else's product.

Any time. personkit export --format=markdown emits your whole corpus as Obsidian-ready markdown files, one per thread. Signed JSONL snapshots round-trip byte-for-byte. The format is open and the relay is self-hostable, so you can walk away from us entirely and keep everything.

The persona is who your AI is with you — voice, values, conventions, refusals, signatures — in a signed git-backed document. The corpus is your operational memory — git commits, plans, sessions, captured conversations — in a local SQLite database with hybrid search. Together they make your AI both recognise you and remember your work.

On your machine. The persona is a git repo you own; the corpus is a local SQLite file at ~/.dotperson/corpus.db. We host nothing by default. The relay handles sign-in, GitHub brokerage and synthesis — it is not a copy of your conversations.

No. Capture is opt-in per surface and off by default. There's a master kill switch, a per-conversation skip toggle in the page, a regex redactor that runs before anything leaves the page, and per-surface health dots so you always know what's being recorded.

Your local corpus database, unless you turn on mirroring for a specific data kind; your Ed25519 secret key, which is generated locally and never transmitted; anything captured while you're signed out; and anything outside the data kinds you've explicitly wired. Email, SMS, notes, calendar descriptions and screenshots are never mirrored by default.

Your persona is signed by an Ed25519 key generated on your machine. Every .person.json commit and every corpus snapshot is signed, so tampering is detectable and round-trip recovery is provable. Harvested payloads pass through a secret redactor that strips API keys, tokens and PEM blocks before any write.

Sign in with GitHub, then run two commands. personkit import synthesises a persona from the context files you've already tuned (CLAUDE.md, Cursor rules, Copilot instructions); personkit setup detects every supported AI tool on your machine and wires them all. Under ten minutes, start to finish.

No. aiperson sits above your assistants, not in place of them. Keep using Claude, ChatGPT, Cursor or a local model — aiperson is the shared memory beneath all of them.

Yes. The relay is self-hostable and the format is open, so power users, researchers and privacy-conscious teams can run the entire stack themselves. See the self-hosting guide in the docs.

The .person Protocol is an open standard for memory, identity, and rights. It is held as a public good by the .person Foundation, a US 501(c)(3) non-profit with an irrevocable charter that forbids conversion to a for-profit. dotPerson PBC, the company you are buying from, is a separate commercial entity that builds and operates products on the open Protocol under a licence from the Foundation. Learn more at dotperson.org.

aiperson is built by dotPerson PBC, a US Public Benefit Corporation, as the first commercial implementation of the .person Protocol. Founder Humphrey Theodore K. Ng'ambi (TK) is a systems architect and cybersecurity engineer based across Johannesburg and Lusaka. The project is open about its structure — the full corpus is published.
