Lodestone, on your own device

The corpus, your memory and Lodestone's safeguards stay on this device. Where Lodestone thinks is your choice: on hardware you own, nothing you say leaves it.

Lodestone is an AI, not a person, and not a therapist or a crisis service. It is made for adults: companion chatbots may not be suitable for some minors. How Lodestone handles a crisis.

Your harmonism.io account

Optional. It holds your Harmonic Profile, and gives ten free messages a day on the models hosted Lodestone runs on. Lodestone works without it.

Where should Lodestone think?

To think with your computer's model, open Lodestone from that computer: in Lodestone Desktop choose Use from Your Phone… and scan the code with this phone, on the same Wi-Fi. That copy of Lodestone keeps its own conversations; Settings → Export memory and Import memory move them across.

On Android, the Lodestone app pairs with the computer instead: it thinks with the computer's model and can share one memory with it, with nothing leaving your network.

Make a key at openrouter.ai. It goes to OpenRouter and nowhere else, and stays on this device, encrypted; if you choose to sync it, it travels encrypted under your sync passphrase. Harmonia never sees it.

Pasting a key tests it at once.

How this works, and how to keep it on your phone

The model files come once from Hugging Face; the corpus comes from wherever this page is served. Nothing is sent back, unless you choose harmonism.io or OpenRouter to think with; then each message goes there, and nothing else. Built on Lodestone's doctrinal backbone and the published Harmonism corpus. Harmonism is a transmission, not a product. See Transmission.

Conversations

    Page readings

    Every page read with the Lodestone browser extension, with its address. Each page is one conversation, kept in your memory and brought here by sync.

      Usage and costs

        Library

        Your path

        Wheel reading

        Your reading of where you stand. When what you tell Lodestone moves a pillar, it asks you to confirm the change; nothing moves without you. The Wheel is the only thing scored here, and it moves only with your life.

        Harmonic Profile

        Practices

        What you have committed to. Lodestone checks in when one is due. Nothing else is tracked.

          The Wisdom Canon

          What Lodestone has learned

          What Lodestone knows about you

          Only what you write here, or ask it to remember. Lodestone infers nothing about your life.

          Share with your guide

          A document of what you choose, made on this computer, for a human guide you work with. It is sent to no one: you give it to them yourself.

          Model

          Life book

          Lodestone keeps what matters of your life (people, health, practices, commitments) as notes in a folder of its own, Lodestone/, inside your vault, which you read and edit in Obsidian or any editor. A note comes back into the conversation, word for word, whenever its subject does. Lodestone writes there only what you keep from a card, never anywhere else in the vault. On a phone or in a browser the life book works too: what you keep is in your memory at once, synced, encrypted, between your devices, and Lodestone Desktop writes it into your vault when it next opens.

          A note's keys: (and its aliases: and title) are the words that bring it back; always: true keeps it in every conversation; recall: false keeps it out.

          Folders Lodestone may read

          Your notes, journal or writings: when a question touches them, Lodestone finds the passages that bear on it and reads them with you. Markdown and text files only. Lodestone only reads: it never changes, moves or deletes anything there, and reads nothing outside these folders.

          Usage and costs

          Past the limit Lodestone stops sending to OpenRouter and other rented models until you raise it or the month turns; a warning comes at 80%. Your own computer's model is never limited. The hard limit is the one you set on the key at openrouter.ai.

          Spoken replies

          This computer's own voices: nothing is sent anywhere and nothing is downloaded. Crisis replies and moments of acute distress are never spoken unasked. On a Mac, better voices come from System Settings → Accessibility → Spoken Content → System voice → Manage Voices… (the Premium and Enhanced ones); Lodestone takes them first. Esc stops the voice.

          Dictation

          The microphone beside the message box. Whisper turns your voice into text on this device: the recording goes nowhere, and the text waits in the box for you to read over and send. In Lodestone Desktop, ⇧⌘D starts and stops; on a Mac, hold fn to speak and let go to write it in (set System Settings → Keyboard → “Press 🌐 key to” to Do Nothing, or macOS acts on fn as well).

          How Lodestone handles a crisis

          Lodestone is an AI, not a person. Made for adults: companion chatbots may not be suitable for some minors.

          Help Lodestone improve

          Share one conversation with Harmonia, so that people at Harmonia can read what Lodestone said: where it held to Harmonism, where it drifted, and whether it held you as it should. Nothing is ever shared unless you do it here. Names are replaced on this device before anything leaves, and you read the whole copy first.

          Using Lodestone

          What this is

          Lodestone is Harmonia's companion. The Harmonism articles and everything you tell it are stored on your own device, and its safeguards run there. The model that answers runs where you choose: on a computer you own, and then nothing you write is sent to anyone; or, if you choose, on harmonism.io's hosted models under your account, or on OpenRouter under your own key, and then each message goes there and nothing else does.

          First use

          Connect to Wi-Fi, choose where Lodestone should think, and press Begin. The corpus downloads once; keep the page open until it finishes.

          On a phone or tablet

          A phone does not run the model. The models small enough to fit answer badly enough to misrepresent the system they speak for, so that option is not offered — a poor answer in Lodestone's voice is worse than no answer. A phone holds the whole corpus for reading and searching offline, and thinks in one of four ways. Your computer: a model on a computer you own, over your own Wi-Fi; nothing leaves your network. Your harmonism.io account: the models hosted Lodestone runs on, ten messages a day in total across the website, Telegram and Lodestone's apps. OpenRouter: a model you rent with your own key, with no daily limit. No model: a question brings back the passages of the corpus that bear on it, with no network at all. Settings → Change where Lodestone thinks moves between them; your conversations stay.

          Keep it on your phone

          iPhone or iPad: in Safari, tap the Share button, then Add to Home Screen. Safari on iOS 26 or later is required.

          Android: install the Lodestone app (Android 7 or later; allow installing from your browser when Android asks). It is this same app, and it can also pair with Lodestone Desktop on your computer: it then thinks with the computer's model, and Settings → Sync can keep its memory in step with the computer without anything leaving your Wi-Fi. Or, in Chrome, open the menu (three dots) and tap Install app or Add to Home screen.

          Mac or PC: in Chrome or Edge, click the install icon at the right end of the address bar.

          Opened from the home screen, Lodestone works with airplane mode on.

          Why Lodestone does not think inside the browser

          Lodestone speaks from the whole of its doctrine on every turn, about fifteen thousand words held beside the conversation. No model a browser can hold carries that and a conversation together, and a lighter Lodestone answering from a shortened doctrine misrepresents the system it speaks for; a confident wrong answer in its voice is worse than none. So it thinks on a computer you own, on your harmonism.io account, or on OpenRouter under your own key. Lodestone Desktop, below, runs a model on your own computer.

          Keeping the articles current

          The articles never update by themselves. When you are online, open Settings and press Check for corpus update. Nothing downloads unless you confirm.

          Moving between phone and computer

          Signed in to your harmonism.io account, Lodestone keeps one memory across your phone, your computer, Lodestone Desktop and the website: sync turns on by itself. Your conversations, notes, Wheel, practices and Harmonic Profile are kept on harmonism.io, encrypted on each device under a key your devices hand to one another, so harmonism.io stores only what it cannot read. A new device asks to be let in: tap Let this device in, then type the code it shows on a device already synced, where the request appears by itself. Settings → Sync turns it off on a device, shows the recovery code, and deletes the synced copy.

          Without sync, Settings → Export memory saves one file with your conversations, practices and notes; import it on the other device. Erasing everything is also there and cannot be undone.

          Lodestone Desktop: Lodestone as an app on your computer

          This is the fuller version of Lodestone, and the one a phone uses when it thinks on your own computer. Install Lodestone Desktop like any other application: for Mac with Apple silicon, Mac with Intel, Windows or Linux (about 400 MB, with the whole English library, the retrieval model and the engine included). On first opening it downloads its model once — from 7 GB, chosen for your computer's memory; Lodestone needs at least 16 GB of memory — with a progress bar, and checks it. There is nothing else to install. From then on Lodestone sits in your Applications folder or Start menu, opens in a few seconds, needs no connection, and carries the whole harmonism.io library in English, with other languages a click away.

          The app is not yet signed by Apple or Microsoft, so the first opening asks for confirmation. On a Mac: drag Lodestone from the disk image into Applications, open it once, then System Settings → Privacy & Security → Open Anyway. Later versions arrive through Settings → Check for updates. On Windows: More info → Run anyway.

          Using Lodestone from your phone

          To use that computer's model from your phone, choose Use from your phone… in the app's Lodestone menu, switch it on, and scan the code with the phone on the same Wi-Fi. Two consequences worth knowing. The phone then works only while the computer is awake and Lodestone is open on it, and that page cannot be saved for offline use — a plain address on your network is not one browsers will let an app store itself from. And what you tell Lodestone there is kept separately from what you tell the computer, because they are different addresses; Settings → Export and Import move it across.

          What Lodestone cannot do here

          Every model Lodestone thinks with can make mistakes and state things the articles do not say — which is why only models that hold its whole doctrine are offered at all. When something matters, read the article: every reply lists the articles it drew on, and they open offline. In a crisis Lodestone gives you a helpline, not a conversation; it is a companion, not a clinician.
