Your judgment, amplified.
Prompts scattered across ChatGPT threads. Half-finished automations. Three subscriptions doing the same thing. There is a better way — one system, dozens of skills, ready on day one.
AI does not replace your business judgment. It gives your judgment reach. One vault. Dozens of skills. Nothing to subscribe to, everything to own.
— Carine Bruyndoncx, Builder of the Business Operating Brain
Real results
from real work.
Built through daily use on real client work. Every skill in the vault exists because it was used on paid engagements first — not built against vendor demos.
Hours returned each week once the vault replaces the scattered tools.
From brief to finished proposal. Previously: two full days.
Own it once. No subscriptions, no lock-in, no upsell tier.
How It Compares
Not another AI course. Not a prompt library. Not a SaaS that owns your data. No upsells, no lock-in, no "enterprise tier" hiding the features you need. See how ThirdBrain BOB compares.

What Early Users Say
I went from zero to a fully working AI-powered vault in under an hour. The skills just work — no prompt engineering needed.
The marketing skill pack alone saved me weeks of setup. SEO audits, content strategy, ad campaigns — all integrated into my client workflow.
Finally an AI system where I own my data and don't pay monthly. Switched from Claude to Gemini CLI without losing a single workflow.
The vault structure is brilliant. Personal notes, company docs, client projects — everything has its place and the AI knows where to find it.
Built by a practitioner, not a product team
I'm Carine. I built ThirdBrain BOB because I needed it — running consulting engagements, managing clients, producing deliverables. Every skill in this vault exists because I used it on real work first.
No vendor pitches. No slide decks. Just a system that works.

Common Questions
When does the ThirdBrain BOB Starter Pack launch?
We're targeting launch in March 2026. Waitlist members will get 48-hour early access before public launch.
What makes this different from AI subscriptions?
You own it forever — one payment, no recurring fees. Your data stays on your machine. Works with Claude Code, Codex CLI, Gemini CLI, and more — switch CLIs without losing workflows.
What AI costs should I expect?
ThirdBrain BOB is BYOK (Bring Your Own Key). We recommend starting with a $20/month Claude subscription to get your feet wet. For intensive daily use, a $100/month Max subscription gives you the full experience.
You can also use other CLI providers as long as the agentskills.io standard is supported. This includes OpenAI Codex, Google Gemini CLI, Amp (free), Block Goose, and many more — no markup from us.
Will there be add-ons?
Yes — lots of free add-ons and a few paid ones will be available at launch. Industry-specific skill packs for SEO, Content, Ads, Video, and more. Every free add-on goes through the same quality control process and is fully integrated into the vault directory structure — plug-and-play, just like the starter skills.
Is there a refund policy?
Yes. 14-day money-back guarantee, no questions asked.
