Try it

Swipe like it's yours.
Watch your agent learn.

These are real cards from Theo's Box. Save the ones you'd want, pass on the rest, and watch the agent take each one.

Turn on scripts to play with it.

In Soul your Onibee grows as you play, and keeps growing as you level up.

How it starts

Sign in with Google, Discord or an email code. Your Box is made the moment you do, and it's yours.

Home

The cards picked for your goals, one at a time. Keep it, skip it, or flip it over for the details.

Who picks

Your cards are picked from what you tell it and what you keep or pass on. Ask for something bigger and our crew answers on your page.

What you get

A daily word game, a read of how you played, a path for each goal, an Onibee (a pet that grows), and a door for your own AI.

Play

One short word game a day, the same words for everyone. Afterwards it reads how you played.

You

Your tree. Each goal is a branch growing out of your Onibee, and a card can start a new branch.

Goals

A card for each goal you're working on, and everything else your Box holds.

Sky

Your Box's own sky, with your name at the center and your Onibee riding it.

What it costs

Your Box is free for anyone, with no limit. Some extras cost coins, which you earn by playing or can buy.

That's Soul.

Your own AI

Your AI reads your Box first.
You keep what it learns about you.

Connect Claude, ChatGPT or Gemini and it reads your goals, what you kept and what you passed on before it answers. Switch it off any time.

How it works

Connect your own AI and it reads your Box before it answers you: who you are in your words, your goals, what you kept and what you passed on. The judgment lives with you, not with them.

Claude connects on any plan, its free one too. ChatGPT and Gemini have read a Box in our test, and may need a paid plan to connect.

It keeps your corrections, not just facts: tell it once that something was wrong, and in that test three AIs followed it. Share what you choose: put something in a room and the friends in it get it in their own AI, while the rest of your Box stays private. A room has an owner and the people they invite, and that's all.

It opens only your Box. You can switch it off any time. We never hold its keys.

Three moves, then it's yours to use however you like.

01 · Start

Tell it who you are.

Three questions, one at a time, then pick one to three things you're into and give your Onibee its color. A closed tab loses nothing.

02 · Play

Play once a day.

A short word game, the same words for everyone. Afterwards it reads how you played, one line at a time, and you answer that's me or not me. It keeps what you confirm.

03 · Grow

Your path grows.

Each goal is a branch of short videos, links and steps. The next card opens when you finish or pass on the one before, and more grow as you near the end.

What we hold, and what we don't

Your answers, your games, your cards and the files you upload live in our database under your Box, and your Box opens only when you're signed in. To pick your cards and build what you ask for, the crew reads it, and so do the AI tools we build with; a card sent to our build floor carries your idea's words and nothing about you. If you connect your own AI, it opens only your Box, and you can switch it off on your You page; we never hold your AI's own credentials. We never sell your data. You can download everything your Box holds whenever you want, and delete it yourself with Delete my Box; it's erased 7 days later. The long version is in the privacy policy.

Questions people ask.

What actually is a Box?

A page about you, in your own words: who you are, what you're working toward, and what you kept and passed on. You play one short word game a day and swipe a few cards. It learns from what you do, not from what you type.

How is this different from just using ChatGPT or Claude?

Each AI app keeps what it learns about you inside that app, and a new chat often starts from zero. Your Box keeps it on one page that's yours. Connect your own AI (Claude on any plan; ChatGPT and Gemini may need a paid plan) and it reads that page before it answers you. Everything it can and can't do there is on the door page.

What does it know about me, and who sees it?

What you tell it, your games, and the cards you keep or pass on, under your Box, which opens only when you're signed in. To pick your cards and build what you ask for, the crew reads it, and so do the AI tools we build with. The game, the read of how you played and your swipes run on fixed rules. Your own AI reads your Box only if you connect it, and only your Box. We never sell your data.

What does it cost?

Your Box is free, with no limit on who can have one. Some extras cost Soul Coins, which you earn by playing or can buy. We never sell your data.

Who's behind this?

Python Visuals LLC, two founders on Long Island, formed in 2026. We build websites and the systems behind them for small businesses. Soul grew out of the system we run ourselves.

Can I leave and take it with me?

Yes. Download everything your Box holds whenever you want. To leave, press Delete my Box on your Box: it closes at once and is erased 7 days later, and Keep my Box brings it back until then. If we ever closed, that download is how you'd take it with you.
