Helping people live well.

EVÐA is a public benefit corporation working on human flourishing, as more of what a person knows, decides and remembers starts passing through systems they did not build and cannot see into.

Living well has always depended on knowing yourself. That is getting harder to do alone, and it is the part worth protecting.

Evolving Data

A record of a person that changes the way they do.

EVÐA is also the platform, and an EVÐA is one person's record: identity, knowledge, resolution and reasoning over a versioned vault, so that a person is not held as an artifact. The record of one should change the way they do, and help them do the changing.

Most systems store what you were on the day they wrote it down and then treat that as what you are. Everything after is an edit to a fixed record, and the version that was true last year is gone.

This one keeps the history and its revision as the same object, owned by the person it describes. What changed is as readable as what is current, so the record can be reasoned over rather than merely retrieved, and no single application holds it.

Make your own

A running journal of your life.

EVÐA is a really organized journal that helps you live your life the more you use it. Freewrite with Iris about the things that stress you out, the things you are uncertain of, the things you do every day that feel slightly off. You get better at seeing your thoughts, at understanding why you do certain things, why certain people matter to you and why you react the way you do.

Suggestions, not answers. Iris cannot give you the right answer for your life, but it is really good at suggestions. Take them, push back on what you disagree with, get specific, and get a new response back. Iris keeps your words in your EVÐA as you talk. It is not a tool to do what you already do a little better; it helps you learn what is worth doing, then do that better, revise, and continue.

Yours, and private. It is not easy to write down thoughts you have not admitted to yourself, never mind a friend or a therapist. EVÐA is designed for exactly that, and it is open source. Your record is plain files on your own machine, and it is never accessible to anyone at EVÐA: the company never receives it. The AI you choose does receive what Iris reads, which is why setup has you turn training off before you start.

Sharing, with circles. Everything is private until you share it. A circle is a part of your EVÐA and who may read it: a sibling, a partner, the public. Ask Iris to share something and it proposes one and waits for your yes.

Setup asks a few questions: what to call your agent (Iris, unless you rename it), who you are, what you want this for, how it should talk to you, and which AI you use. It works with any coding agent that can read a folder of files: Claude Code, Codex, Cursor, GitHub Copilot, Windsurf, Zed, opencode, Gemini CLI, Aider and others. The Claude desktop app works too, once its Filesystem extension is pointed at the folder. Claude and ChatGPT used through a Project in the browser cannot read or write it, so setup offers a one-time import of what a chat app like that already knows about you instead. Dictation helps: Apple's built in dictation, or Wispr Flow with data collection off. Node 20 or later.

EVÐA prescribes no values and no rules. The only requirement is that you want to, and you are open to it. It is built on a neo-Aristotelian philosophy; ask your agent about it, ask ours on evda.io below, or have any agent verify it in the open code.

If you would rather start from a vault of notes and a thinking partner, the Iris Vault is that. Ask Iris what it is and how to set it up.

Ask

Ask about EVÐA.

This answers from EVÐA's own published material: the welcome statement, the substrate's README, and the guarantee above. It knows nothing about any individual person's record, and it will say so rather than guess.
