Your second brain should remember how you decide
I extract how you actually think and install it into Claude + Notion. The result is a second brain that carries your judgment, standards, corrections, and decision rules into the work you do every day. It knows the business, remembers what changed yesterday, and keeps permanent changes behind your approval.
One owner. One build. Done in 3-5 days.
Every new AI chat starts with you rebuilding yourself.
Explain the business again. Paste the background again. Fix the voice again.
BigBrainOS gives that work a memory. Your second brain carries your judgment, standards, corrections, and decision rules into the work you do every day.
Here's everything you get
Your complete Cognitive Fingerprint
25-30 pages documenting how you think at all four levels: your decision rules, voice, priorities, and blind spots, tied back to source evidence.
BigBrainOS installed in Notion + Claude
Your Fingerprint built into the tools already producing your work, with a system that can process your real meetings, email, notes, and docs.
Custom Claude Skills
AI trained on your voice, frameworks, and decision-making patterns, built for the work you repeat.
Implementation support
I install the system, run one piece of your real work through it, and calibrate it until the workflow works end to end.
Investment
$3,000
Done in 3-5 days
I take four builds a month because each one needs careful extraction, installation, and a real proof run on real work.
If the installed system can't take one real source item from intake to review packet by the end of calibration, I keep working at no extra charge until it can.
Need your judgment installed beyond your own second brain?
BigBrainOS starts with one owner. When the same judgment needs to reach a team or a whole company, the build expands with it.
BigBrainTeams
Install your Cognitive Fingerprint across your founder and 5 key team members, so everyone operates with the same judgment.
