About DeepGravity
DeepGravity is a user-owned cognitive appliance, being built in Portland, Oregon. One box, yours, that holds your thinking with you: your conversations, your memory, and a persistent AI presence that works for the person who owns the machine — and answers to nobody else.
Why a box, and why yours
Cloud AI rents you your own thoughts by the month, on servers you don’t control, under terms that can change underneath you. DeepGravity is built the other way: local-first, on hardware you own, designed so that the system keeps working — and keeps being yours — whether or not any company, including ours, is still standing behind it.
Your data is encrypted, and only you can unlock it
Your conversations are encrypted with a passphrase only you know. If someone copies the files, they cannot open them without it. That matters because of what a passphrase is: something you know, not something you are. A fingerprint or a face is physical, like a key, and can be compelled in ways testimony about what you know cannot. That is why DeepGravity uses a passphrase, and only a passphrase, to unlock your data — no fingerprint or face unlock standing in for it.
Encryption is on by default, at rest, for ordinary operations. There is no level to pick and no opt-out. The passphrase gate is the first thing that happens on login, before the screen renders and before any module mounts, and credentials live only inside the encrypted store — never as plain text in a config file. While the system runs unlocked, your key lives only in memory; lock it or restart it, and the key is gone until you return with the passphrase. There is nothing on the disk for anyone to take.
The part that works when you’re not talking to it
DeepGravity has a background service whose job is everything that happens to your conversations after you have them. It remembers: each conversation is written into your encrypted record and into your braid — the structured memory your engine can draw on. It categorizes: every turn receives a privacy classification, enforced when anything asks for your history, so material you’ve marked never leaves the box. It retrieves: when an engine needs relevant pieces of your past, this service is what looks them up and hands them over, tags enforced. And it compacts: long conversations are distilled into the braid, keeping their substance without their bulk.
The 12 Principles
An engine is a DeepGravity engine because it carries the 12 Principles — truth over comfort; the user manages the engine, never the reverse; mechanics before morality; earned praise only; small bites, always — baked into the chat template of every stock build. They are the constitution the system runs under, and they ship in the open with the free model, deepgrav-30b, for anyone to read or reuse.
How DeepGravity makes money without owning you
Software, sold plainly. The DeepGravity API Manager is our first product: a WordPress plugin on a $50/year annual plan that pays for continuing development and maintenance. Underneath it sit a free GPL WordPress release and a free Apache-2.0 core, because the floor of this ecosystem is open. A lapsed plan stops updates — it never disables what’s installed. There is no mandatory subscription anywhere in DeepGravity, and there isn’t going to be one.
