Who this is for

Business owners, knowledge workers, and founders who want their notes, ideas, and decisions to compound.

  • Business owners with 5+ years of notes scattered across apps
  • Founders who think faster than they can capture
  • Knowledge workers who keep re-Googling what they already learned
  • Coaches and consultants whose IP lives in their head

What you ship

A living personal knowledge base in Obsidian, maintained by Claude Code, that compiles, cross-references, and answers from your own thinking.

Hours back from re-finding what you already knew
  • Obsidian vault structured as an LLM Wiki
  • Claude Code agents writing pages from raw input
  • Daily ingest ritual locked in
  • 1,000+ pages compiled and cross-referenced
  • Personal output workflows wired to the vault

You went from note-taker to knowledge architect. Your second brain runs while you live.

Your instructor

Rajiv [last name]

Founder. Operator. Florida-based. Builds AI systems for himself and ships the patterns to you. Bio placeholder for Rajiv to personalize.

Real questions. Real answers.

Who is this cohort for?
Business owners, knowledge workers, and founders who want their notes, ideas, and decisions to compound.
How is this different from First AI OS?
Second Brain organizes your knowledge so you can think and write faster. First AI OS automates 5 real flows that save 15 to 30 hours per week. Most people do Second Brain first.
What are the prerequisites?
Complete one free workflow (Leader, Worker, or Solo) before applying. We check.
What if I fall behind?
Every session is recorded. Slack stays open the full cohort. Rajiv answers questions in Slack daily. Office hours give you a 1:1 if you stall.
Payment or transfer policy?
All sales are final and seats are limited, so we do not offer refunds once you enroll. If you cannot continue, you may transfer to the next cohort with 7 days notice. Try the free workflows first to confirm it is a fit.
