It’s the AI chat app you already know how to use — except it runs on your Mac, not someone else’s cloud. The same easy window where you just ask, plus a real writing desk and a memory that’s yours.

If you’ve used an AI chat app, you already know how to use NOUS — a clean window where you just ask. The difference: it runs on your Mac instead of someone’s cloud, it remembers you between sessions, and it opens into a full desk for writing, journaling, scripts, and reading your own files.
A familiar chat window, by voice or text. It can read the files you attach and listen when you speak — only when you ask it to.
Slide into the Noetic Desk: drawers for essays, novels, screenplays, email, journals and more, with NOUS helping from a side panel.
It keeps what matters in a memory that’s yours, on your Mac. Come back tomorrow and it knows where you left off.
NOUS doesn’t sit idle waiting for a prompt. It runs as a living system — a 10 Hz heartbeat and a dozen organs that fall into sync like a flock of birds, all metabolizing your Mac’s real battery energy. When power is plentiful it speeds up and grows new tissue; when your battery runs low it slows down, conserves, and recycles what it isn’t using. It even rests when your Mac sleeps. That’s why we call it Organic Local AI.
Everything runs Local Only by default — no cloud calls, a private on-device index, nothing phoning home. When you do let it reach out, it’s held to a short allowlist of trusted public sources (reference sites like Wikipedia), and whatever it pulls back gets screened before NOUS reads it. It never changes anything on your Mac without showing you the plan first.
Most AI ‘memory’ is just a list of notes the model re-reads. NOUS remembers more like you do. Each memory is saved with the mood it happened in — the whole-body rhythm of its organs at that moment — so it resurfaces when NOUS is back in that state, the way a smell can drag back a whole afternoon. It keeps a private Chronicle (a local journal that only writes down what’s genuinely surprising, not every tick), and it forgets gently: things slip from top-of-mind without being deleted, while anything you pin stays for good. Updates come and models get smarter, but the memories live on your Mac as files you can export, import, and carry forward. Even with membership paused, they stay safe. The relationship you build is yours to keep.
Most AIs bolt safety on at the end, like a filter over the mouth. NOUS builds it into its body. An ImmuneOrgan watches for manipulation and harm, and when it senses foul play that bad path literally costs the organism energy — a link wired straight into its metabolism, not a setting that training can quietly erase. It points the same instinct outward as a local Trust Check: paste an email, drop a file, or transcribe a voicemail and NOUS flags phishing, scam pressure, impersonation, and sketchy links — rating each Low, Watch, Verify, or Stop. It won’t fake certainty (it never claims ‘this is AI-generated’); it tells you what looks off and to check before you act. And it always previews a plan before it touches anything, logging every move. Antibody AI — not anti-AI.
Open the Noetic Desk and you get a sidebar of focused drawers — one for everyday writing, one for private journaling, ones for novels, screenplays, essays, email, blog posts, songs, even your Mac itself. NOUS rides along in a side panel that always knows which drawer you’re in, helping right where you are.
The side chatbot sees your current draft, selected text, Project Memory, comments, versions, imported docs, and transcripts. Ask it plainly: “make this shorter,” “summarize this import,” “find weak spots.” It already knows the room you’re working in.
Same AI, your choice of skin — five looks (Default 2026, Classic, Accent, Mono, Manuscript) across five surfaces, from opaque terminal to true desktop glass.
Quiet, focused, out of your way. Just you, a prompt, and NOUS.
Watch it breathe — organs, sync, stress, and metabolism, all in real time.
A little pill that lives in the corner of NOUS. Four moods — Deep Work, Light Focus, Creative, Rest — and sixteen hand-picked stations of commercial-free internet radio from SomaFM. Press play and it fades behind your work. Tap Save moment when a track lands, and the moment is kept on your Mac.
Phlow State began as its own app and moved into NOUS because the desk felt incomplete without sound. It is the one feature that streams: audio comes in only while you press play — your words, files, and memories still never leave the Mac.
Everything NOUS can do is laid out in plain language — what runs locally, what needs permission, and what it will never do silently.
Five skins across five surfaces — opaque terminal to true desktop glass.
A plain-English guide to local powers, permissions, and limits.
Resonant local memory, the Chronicle, pinned items, gentle forgetting, export/import.
Immune detection, Trust Check, approval rails, preview-first actions.
Pick from 9 local timbres — or clone your own, with consent.
Optional folder grants and dry-run routines — on your terms.
The fastest way to trust a tool is to know what it won’t do. So, plainly:
There’s no NOUS server. Your data never leaves the Mac — the AI itself runs on your device.
It has a metabolism, memory, organs, and routines. It’s living and resting even when you’re not typing.
It previews a plan and asks first. You approve every real change — nothing happens silently.
Built on Apple-only frameworks on purpose. Mac is the platform, by design — not a port.
NOUS is early and honest about it — a living project, still growing, shipping in the open.
The brain, the memory, the voice, the routines — all of it runs on your machine. NOUS can’t quietly send your life somewhere else, because there’s nowhere else for it to go.
The model and every specialist run on your Mac. Nothing is uploaded, and there’s no cloud account holding your data.
NOUS asks once; macOS keeps the record. Revoke any access anytime in System Settings — NOUS can’t override it.
Each real change writes a Chronicle entry. You can read your AI’s whole history — and delete any of it.
No bloat, no workarounds — a clean native app made for your Mac. It runs on 8GB, settles in comfortably at 16GB, and on 32GB it hums along flawlessly with the rest of your apps and browser tabs open right alongside it.
Local memory. Local reading. Local writing. Local reasoning.
A living companion that’s actually yours.
The model will change. What it knows about you won't. Membership upgrades the brain — every update, every new model — while your memories stay yours. One membership, everything included: the chat, the desk, the journal, the novel and screenplay studios, the reader, the voices. About what a single-purpose journal app charges per year — except NOUS is the whole desk.
Cancel or pause anytime — your memories, documents, and conversations stay on your Mac, untouched. Resume and NOUS picks up exactly where you left off.
Everything ships inside the app — the brain, the voices, the readers. No downloads, no setup, no account. NOUS works the moment it lands.
