Private AI chat & agent workspace
Escape from AI that owns you to AI you own.
Your work stays in your browser, encrypted, and the code is public for anyone to check.
Daimond is in closed beta, so an account needs a passcode. Already have one? Open Daimond, or see how it works.
Most AI apps rent you access and keep your data. Daimond charges for the service and stays out of your work.
The frontier models you already pay for, in a workspace you own. Your work is yours, and you can leave with it any day.
Daimond is different
-
Your life
It remembers, in pieces you choose
Daimons (DY-mon) are agents that each remember one facet of your life, a project, an essay, a client. These “diamonds” link into a graph and can draw themselves as working pages; one, Log Life, is built in.
-
Your work
A desktop in any browser
Read, write and edit common files in the browser, a private desktop. Direct agents that spawn workers, sync across browsers with Pro, and keep it all on your own device.
-
Your freedom
An escape hatch from extraction
No lock-in, no opaque quota. You see the exact model you are using and watch every credit and context cost as it runs. Leave any day, and your work comes with you.
How it works
Daimond runs in your browser, so before it can do anything you have to give it a model to talk to. There are three ways to do that, and the one you pick decides who apart from you can read what you write.
-
Use a key you already have
Your provider can read it, because they run the model.
Paste in a key from a provider you already pay, and your browser calls that provider directly. The key stays on your device and the inference bills to your account with them, at their price. You need no account with us, not even a free one.
-
Buy credits from us
The model host can read it, because they run the model.
Bring nothing. Top up an account, pick a model, and pay for what you use. Everyone else who sells inference relays the request through their own server, which would put your work in front of ours. Daimond does not relay it. The gateway mints a key at the model host, capped to a small spend, and hands that key to your browser, which then makes the call itself.
Paying us does not put us in the path. Open your browser's network panel and watch where the call goes. We learn that a call happened and what it cost, and never what was in it.
-
Run a model on your own computer
Nobody else can read it.
Point Daimond at a model running on your machine or your network. No provider, no gateway, no account anywhere. If that is not you today it can be later, because the three mix chat by chat.
Only self-hosting a model guarantees total privacy, and the diagram shows why. Pro can also store your work in the cloud, end-to-end encrypted, so we hold it but cannot read it.
For developers: run a small Rust helper beside a browser extension, point Daimond at a folder, and agents read, write and run tools there, fenced to that folder with every command logged. Compile it yourself. Developer guide.
Getting started
Open a tab, and get to work
No sign-up form, and no server of yours to run. While the beta is closed, a passcode gets you through the door.
-
Open it
Daimond is a web page, and installs as an app if you want an icon of its own. The account it offers you on first run is a name and a passphrase it generates, both kept on your device.
-
Bring a model
Your own key, credits, or a model running on your machine. Swap between them whenever you like, chat by chat.
-
Work alongside it
Ask in plain words and it acts, reading your files, searching the web and drafting your mail beside the conversation. Set it something bigger and it fans out into several agents at once, each spending its own capped key, each priced on screen as it runs, and one click holds the lot.
-
Fold what works
Good thinking goes into a diamond, a place that keeps it, instead of into a chat thread you will never find again.
Diamonds
Everything you know about one thing, in one place
A chat thread is a transcript you lose. A diamond is a place that holds everything you know about one subject, written into a plain file called a crystal and handed to every agent that works there. Start a new chat, or send out four agents, and they all already know.
Nothing is absorbed behind your back. You choose what gets folded in, and the crystal stays a file you can read, edit, or roll back to any version it has ever had. The file belongs to you, so it outlives any one model and comes with you when you switch.
The agent that works there, your daimon, can also draw the crystal as a working page. Ask for a diet log and you get tiles you tap, the day's total and a chart of the week; what you tap is written to a file beside the page, inside that diamond, on your device. We call it a capp. It runs sealed off, with no network of its own and 64 KB for the whole page, small on purpose, so what it records stays yours.
Name a diamond, tag it, then type a tag to pull up everything that shares it.
Don't trust us. Check.
Everyone says “private”. Daimond lets you test it. The app is compiled from Rust to WebAssembly and runs on your device, your content is encrypted before anything is sent, and the gateway only ever holds a key it cannot use and parcels it cannot open.
-
Read the code
The whole client is public. Read it, build it, and check it yourself.
-
Check the running site
Every build rebuilds byte for byte from that source and is sealed into a public transparency log. Check the running app now and it will hash what your browser was served and compare it against that seal.
-
Watch the wire
Open your browser's network panel while you work. With your own key, your chats and files never leave in the clear, and only ciphertext reaches our servers.
-
Leave whenever
Export your whole workspace and identity and walk. Nothing is trapped on a server, and there is no content on our side to spill.
Built on Hematite, Oxedyne's from-scratch Rust library. An independent audit is planned, so in time you need not take even this on faith.
How it compares
Each of these corners is easy to close on its own. Closing all of them at once is the rare part. Free tools are free because you host and support them; Daimond is the same privacy with nothing to run.

The three columns are archetypes and the names under them are their best-known examples, so a row describes the kind rather than any one product. None of them closes every corner, and the one private workspace among them is a narrow note assistant you cannot check the way you can check this one.
What it costs
Closed beta Nothing is on sale yet, and an account still needs a passcode. This is what Daimond will cost, so you can judge it now.
Free to start
$0
- Chat with any model you bring a key for, billed at cost with no markup
- Read, write and edit your files
- Fold chats into diamonds that sharpen over time
- Local-first, encrypted, private
Pro
$8 a month
- Cross-device, end-to-end encrypted sync
- Cloud file storage, 256 MB free
- Mail from your own mailboxes
- Away for a month? Billing pauses by itself and picks up when you return, so you never pay for time you didn't use.
- Cancel anytime; the free app keeps working, only the Pro services stop
Credits are separate and pay as you go, whether or not you have Pro. They cover the metered extras, running a model without your own key, searching and reading the web, and cloud storage past the free 256 MB.
Two of the Pro services do send your work to our server, so this is the place to say so. Turn on sync or cloud files and we hold it, encrypted on your device before it leaves and stored as ciphertext we have no key for. One more party holds your work, and nobody new can read it.
Daimond is made by Oxedyne, an independent Rust and web shop in Perth, Australia. We wanted a better way to work with AI, so we built the tool we wanted and use it every day. It keeps getting better the longer you use it, with your workspace and settings untouched.
The name is diamond crossed with daimon, the go-between spirit in Plato that carries word between gods and mortals. Daimond stands in that place between you and the frontier models, on your side. The figure reaching for the light in our mark is you.
Come and test it.
Ask for a passcode and start today, or leave your name and we will write when the beta opens.
