Account & website

This page explains the parts of ArchHub that sit around the work: how you sign in, where your account and plan live, how billing works, and where to find your synced brain. It is written for the person running the firm, not a developer — no terminal required.

There are two places you’ll touch your account:

• The desktop app (the studio where you actually do the work).
• The website, archhub.io (where you download the app, sign in, and check your plan from any browser).

Both read the same account, so your email, plan, and remaining messages match wherever you look.

1. Signing in (or signing up)

ArchHub uses magic-link sign-in — there is no password to remember.

From the website

1. Go to archhub.io.
2. In the top navigation, click Sign in (or Get started if you’re new).
3. You land on the Sign in page. Enter your email address.
4. ArchHub emails you a link. Open the email and click the link — that signs you in.

No credit card is required to create an account. New accounts start on a free tier with a set number of trial messages included, so you can try the product before paying.

From the desktop app

The first time you launch the app, a short first-run setup walks you through signing in to a cloud model using the same magic-link flow. Once you’re signed in, the app remembers you.

A note on “Sign in with Google”: the Google sign-in button may appear, but Google sign-in is not switched on yet — it needs configuration on our side first. For now, please use the email magic link, which works today. Google sign-in is coming soon.

2. Where your account lives in the app

When you open the desktop app you land on the Home view. Home shows three things tied to your account:

• Your recent sessions — a grid of cards (with thumbnails) for the graphs you’ve been working on, so you can jump back in.
• The account chip — shows your email, your plan, and how many messages you have remaining. These are read live from your real account — nothing here is hardcoded.
• A graph-health indicator — a small chip/badge that tells you the health of your current work and opens a real detail view when clicked.

To change account-level things, open Settings. The account settings open in a native dialog that shows your email, plan, and remaining messages, pulled from your live account. Settings is also where you manage your AI model providers, the model router, permissions, theme, and accessibility preferences.

3. Your account on the website

You can also check your account from any browser without opening the app.

1. Go to archhub.io and Sign in (magic link).
2. Use the Account link in the navigation.
3. The Account page shows your email, your plan, and your messages remaining — the same numbers you see in the app.

The website navigation also gives you the rest of the public site: Home, Features, Pricing, Community, Security, and Changelog, plus Download (to get the desktop app) and Get started.

4. Your license and plan

ArchHub has three tiers — Solo, Studio, and Firm — plus a free trial tier for new accounts. Your tier governs how much you can do (for example, the caps on your usage and how your brain scales).

There are two ways to run the AI behind ArchHub:

• Bring-your-own-key (BYO): you plug in your own model provider key, and ArchHub uses it.
• Hosted AI: ArchHub runs the model for you through its cloud, metered in messages.

You can see which plan you’re on, and how many messages remain, from the account chip on Home, from Settings, or from the Account page on the website.

Buying and managing your plan

• Pricing lives on the Pricing page.
• Plans are billed through Stripe (with Polar as an optional alternative). There is also a message credit pack — roughly $10 for 1,000 messages — for topping up hosted-AI usage.
• A billing portal is available to manage your subscription after you’ve purchased.

Heads-up on purchasing: live checkout and the published prices are still being finalized. Where a plan isn’t ready to buy yet, you’ll see a “Coming soon” label instead of a checkout button. Treat live purchase as coming soon rather than guaranteed today.

A note on free cloud AI: a zero-setup free cloud model is not promised yet. If you use hosted AI without a configured key or credits, a request may be declined until billing or a key is in place. The reliable free path today is the trial messages on a new account, or bringing your own key.

5. Your brain (and where it lives)

The brain is ArchHub’s personal memory. It learns from your work and feeds context back into the app so it gets more useful over time.

• In the app, you can browse your brain directly: a Brain browser and a folders view organize your facts into folders and facets, and you can search, browse, and view individual facts and memories. You can also see brain status and statistics, and add memory facts.
• Cloud backup / sync: the desktop app can push your brain to the cloud as a backup. This sync is write-only and strips secrets before sending — it copies your knowledge to your own private per-user replica, it does not pull a shared brain back down.

The brain portal on the website

The website is intended to give you a brain portal — a place to see your synced cloud brain after signing in. Today this portal is still being built (it is a work in progress and not yet a finished, shipped feature). For now, the in-app brain browser is the reliable place to explore your memory. The web brain portal is coming soon.

6. Getting started, end to end

A clean path for a brand-new user:

1. Install the app (Windows, no terminal needed). From archhub.io click Download, or install via winget install Fargaly.ArchHub. You can also download the ArchHub-Setup installer from the project’s GitHub releases and double-click it. The installer adds a desktop icon and a Start-menu shortcut.
   • On first launch you may see a Windows SmartScreen warning (until the app is code-signed) — this is expected; choose to run anyway.
2. First launch & sign-in. The app opens and walks you through signing in to a cloud model with a magic link — free tier, no credit card, trial messages included.
3. First action. You land on Home (recent sessions + account chip + graph health). Create a session, open the canvas, and start working — type in the composer to drive your graph, or drop a connector node and run it.
4. Check your account from the web anytime: visit archhub.io → Account to see your plan and messages remaining.

Known launch issue (workaround): on some NVIDIA graphics cards the app window can open blank. If that happens, set the environment variable ARCHHUB_VERIFY_NO_GPU=1 and relaunch. An automatic fallback for this is on the way.

Quick reference

Coming soon: Google sign-in, the website brain portal, finalized live checkout, a zero-config free cloud model, and automatic GPU fallback.
