Capture any thought, link, video, or file. Cranium files it under the right vault, connects it to your priorities and goals, and helps you turn what you save into what you actually do.
Cranium is your filing cabinet, your priority board, and your second brain — in one place. You drop ideas in. The system organizes them, connects them to what you’re working on, and surfaces what they actually mean.
Connect the channels you already read. Cranium pulls every new item the moment it drops, summarizes it, transcribes the video ones, and files it under the vault it actually belongs to. The longer you use it, the smarter your account gets.
Every goal and priority has a trajectory. You tell Cranium how it’s going, on a slider from drifting to moving. Those signals stack into a line you can read at a glance — and a Sunday letter that tells you the truth.
Vaults are folders for the parts of your life that matter. Drop captures in by hand or pipe in YouTube and RSS. Once a vault has a few captures, Cranium reads across them and writes what you’ve come to know — the patterns, the through-lines, the open questions.
Vaults are folders for what matters in your life. Trading. Health. Family. Premium.Chat. Set them up once. Every capture you make — by hand, from a YouTube channel, from an RSS feed — drops into the vault it belongs in.
Pin a YouTube channel or RSS feed directly to a vault and new episodes arrive pre-filed. Cranium scrapes the transcript, strips the SUBSCRIBE-and-LIKE boilerplate, and writes its own summary on the way in.
No more sprawling notes app you can’t find anything in. The captures live where they belong.
Once a vault has more than a handful of captures, Cranium reads across them and writes a living summary — what the patterns are, what the through-lines are, where the open questions sit.
You don’t have to remember which video said what or which note made which point. The vault knows. The longer you use Cranium, the sharper that read gets.
Same captures you would’ve saved anyway — just compounding into wisdom instead of piling up as clutter.
Open any capture, priority, or goal and ask. Cranium pulls in what you’ve saved, what your vaults have come to know, and where you said you wanted to go. The reply comes back grounded in your actual context — not generic advice.
“Three threads. Stephan’s thesis on Tesla parallels what you saved from Dumb Money two weeks ago — both treat the EV multiple as a battery story, not a software story. Your Trading vault has 14 captures on margin compression, and that’s the lens you keep returning to. The open question your vault has surfaced is whether margin compression is cyclical or structural — Stephan implies cyclical, your earlier reads on Munger imply structural. Worth sitting with that disagreement.”
