Stop re-explaining your business to ChatGPT every morning.

ThirdBrain BOB — for your own business

BOB holds your client history, your decisions, and your operating context. Every workflow starts from where you left off — not from a blank chat window.

One-time purchase. Yours forever. No subscription.

What you get

Own Forever

One-time purchase. No subscriptions, no subscription cliff. Your data stays local — no cloud dependency.

Context That Persists

It learns your business and never forgets. Every skill starts from your actual context — clients, decisions, history — not a blank prompt.

Decisions to Deliverables

Type a business question, get a proposal, a plan, or a marketing brief. Not advice you still have to turn into something.

What's inside

Enforced Data Model

Every client, project, decision, and deliverable is structured automatically. Your notes link to each other. Dataview queries just work. No orphaned files, no broken context.

Customizable Workspace UI

Your dashboard, configured for your business. The BOB Workspace uses Obsidian Bases to surface what matters — without digging through folders.

Hundreds of Skills — and Growing

A core library, plus add-on packs

The Starter Vault ships with a broad core of production-ready skills — marketing, sales, finance, operations, and documents — ready on day one. Free and Pro add-on packs extend it further (SEO, content, ads, video, and more), all quality-checked and plug-and-play into the same vault.

Common questions

Do I need to be technical? You don't need to be a developer. BOB is structured workflows, not software development — you follow a setup guide once, then run business commands in plain language. Setup involves a desktop AI CLI and Obsidian, so expect to follow a few install steps rather than a one-click download.

What AI model does BOB use? Any of them. BOB integrates with your AI coding agent through the Agent Client Protocol (ACP) — Claude Code, Codex, Gemini CLI, Amp, Goose, and others — so you use whichever model you prefer, on the subscription you already have (or an API key, if that's how you'd rather connect). No separate subscription for BOB.

What happens after I buy? Your purchase unlocks a course in our Skool community that holds your download link and the "Start Here" walkthrough, guiding you through installation step by step.

Is there a guarantee? Yes — an operational-by-day-30 guarantee. If BOB isn't running for you after your first 14 days, we work with you over the next two weeks to get you fully operational by day 30 — or your money back. We don't do walk-away refunds — that leaves you stuck with the original problem.

I'm a consultant or agency — can I deliver this to my clients? Yes. See BOB for Agencies for the licensed delivery model, branding, and partner support.

What do I need to run it? A desktop computer — Windows (with WSL), macOS, or Linux — plus Obsidian (free, recommended) and an AI coding agent you connect via ACP — Claude Code, Codex, Gemini CLI, and others — using your existing subscription or an API key. You can view and sync your vault on mobile, but the AI workflows run on desktop.

AI that knows your business. Yours forever.

One purchase. No subscription. Point it at your business and go.
