See what your portfolio will actually do — in plain English and real dollars. Then plug the same data into ChatGPT, Claude, or Gemini with one click.
Historical analysis, not predictions. We show the math; you make the call.
Pick a starting point, adjust the mix, and watch how $10,000 could grow based on the last decade of real market returns.
Every chart on Folio comes back to these four. Once you know what they mean, you can judge any portfolio in 30 seconds.
How much it grows in a typical year. The average annual gain, based on the last decade of real market data.
How bumpy the ride is. Higher volatility means bigger up-and-down swings along the way.
The worst pain it's ever caused. The biggest peak-to-trough loss you would have lived through.
Your risk-adjusted score. Higher is better — it's how you compare two portfolios fairly.
Two accounts, eight knobs, and a projection funnel that shows every outcome between worst case and best case. Move the sliders — watch the future change.
Institutional-grade math, translated for humans — and a handful of honest commitments about how we operate. Whether you're starting out or running a $5M portfolio, you get the same numbers and the same promises.
No black boxes. Every number shows its work — what went in, what came out, and why it matters. If you can't verify it, we shouldn't be asking you to trust it.
"Sharpe ratio" becomes "return per unit of risk." "Efficient frontier" becomes "the best mix for your risk." Math stays the same. Words get better.
We don't manage your money, earn commissions, or take referrals from brokers. The math is the product. You make the decisions.
We never sell it. We never use it to train models. With MCP, it can stay on your machine entirely when you want it to.
No hidden affiliate links. No "recommended" funds we get paid to promote. The page you see is the page everyone sees.
Every calculation has a "show your work" link with the formula, inputs, and assumptions. Disagree with our defaults? Change them.
Before you optimize the future, get honest about the present. Same math, same palette, same "show your work" philosophy — applied to the paycheck hitting your account this Friday.
Plug Folio into ChatGPT, Claude, or Gemini in under a minute. Your AI gets real numbers from your real portfolio — instead of making things up. (Folio ships as an MCP server, so any MCP-compatible client works.)
One click. It's the same MCP standard every major AI now speaks.
Claude Desktop, ChatGPT Custom GPTs, Gemini function calling, Cursor, or any MCP-compatible client.
"Stress test my 60/40 against 2008." "What's my blind spot?" Your AI now has real tools, not just vibes.
Either way, you'll know more about your portfolio in five minutes than you learned in five years of account statements.
