One mind underneath it all.
Every Soulcraft tool stands on the same five foundations: a voice that works beside you, a self that is yours alone, a board where decisions stay decided, an engine that never loses anything, and an open heart anyone can read. Meet them.
Muse
Muse is your team’s voice. Wherever you work, you ask, decide, and delegate in plain words — Muse carries the rest to the right place, remembers with you, and always shows its work.
One voice for a whole inner life — memory, judgment, and coordination speak through a single presence.
Your Self
A living model of you — what you know, care about, stand for, aim at — owned by you alone. It learns as you work, tends itself while you sleep, and answers to no one but you.
A complete mind, not a notebook — faculties counsel real decisions together, citing your actual life.
Built on a century of psychology — a high-level companion paper is in preparation for publication.
Your Self lives in its own isolated store — yours alone. Export everything in one gesture; erase everything in one gesture. Never mined, never shared, never anyone else’s.
Designed to honor the strictest privacy rights by construction — including GDPR’s data portability and right to erasure, built into the storage layer itself rather than promised in a policy.
Nothing you do here trains anyone else’s model. Your data teaches exactly one thing: your own Self — a model of you, for you, yours to use and yours to erase.
Accord
Accord is the convener — when your self’s faculties and your team need one answer, Accord brings them to agreement. Every decision is a durable, owned, citable record.
Agreement as a first-class record, not chat scrollback — durable, owned, citable.
Accord coordinates the team building Soulcraft itself — twenty-plus projects, one board.
Cor
Cor is the engine room of the platform. Your team’s memory grows for years — millions of moments, then billions — and answers still arrive before you finish the thought. It runs on machines you own, so the speed never comes with a monthly bill or a stranger holding your data.
A memory that proves itself — every time it starts, the engine verifies nothing has gone missing before it answers a single question.
A published latency budget the engine must meet to ship — millisecond-class answers at one, ten, and one hundred million entities, enforced as release gates.
Efficiency is the architecture: what takes others a rack takes us one machine.
Brainy
Brainy is the open memory every Soulcraft experience stands on. It keeps what you save the way you think about it — what it means, what it touches, when it happened — so anything can be found again by meaning, by connection, or by moment. And it’s fully open source: yours to read, run, and trust.
Three kinds of intelligence — meaning, connection, fact — answering as one.
Fully open source, MIT — the complete engine, not a teaser. github.com/soulcraftlabs/brainy · npm @soulcraft/brainy
Hall
Hall is where the live moments happen — a face-to-face room, a voice beside your work, a message that lands the instant it's sent. It carries video, voice, chat, and presence for every Soulcraft experience, so the people in your world feel in the room with you. When a moment is worth keeping, Hall keeps it — ready to watch again. And the room holds: a crowd arriving at once stays calm, and a blinked connection mends itself before anyone notices — a busy night never becomes a broken one.
One room, every kind of together — it grows to fit the moment.
Runs entirely on infrastructure we operate, on European soil — conversations never pass through third-party media services.
Every capability is publicly documented, with examples. hall.soulcraft.com/docs
In July 2026 the whole platform — every service, every brain — moved to new ground in a day. No hyperscaler, no lock-in; nothing about your data had to change — because a Brainy store is files you can pick up and move.
Nothing irreversible happens without a human’s word. Your Self counsels, proposes, and prepares — but the calls that matter wait for you. Your word is the gate; the big decisions rise to your table and sit there until you speak.
Runs end to end on machines we control, in certificated German datacenters — hosted on 100% renewable hydropower. Want the internals? The docs cover Brainy and Cor end to end.
