## 2. Deterministic State Estimation
 
Core control loop executes deterministic state estimation over 200 Hz boundary:
 
$$V(x) = \frac{1}{2} x^T P x + \int_0^t \gamma \|u(\tau)\|^2 d\tau$$
 
Where $P \succ 0$ satisfies continuous-time Riccati bounds:
 
$$A^T P + P A - P B R^{-1} B^T P + Q = 0$$
 
> "Deterministic convergence guaranteed within 14 ms for perturbations."

2. Deterministic State Estimation

The core trajectory planner executes deterministic state estimation over a 200 Hz boundary. System stability is proven through the Lyapunov function P≻0P \succ 0:

V(x)=12xTPx+∫0tγ∥u(τ)∥2dτV(x) = \frac{1}{2} x^T P x + \int_0^t \gamma \|u(\tau)\|^2 d\tau
(2.1)

Where the algebraic Riccati matrix satisfies positive definiteness for all disturbances bounded by Ω⊂Rn\Omega \subset \mathbb{R}^n:

ATP+PA−PBR−1BTP+Q=0A^T P + P A - P B R^{-1} B^T P + Q = 0
(2.2)

"Deterministic convergence is mathematically guaranteed within 14 ms for all initial state perturbations bounded by the stability envelope."

Formulas & Diagrams

Mermaid, LaTeX, tables, and code render directly.

Write standard math formulas and technical diagrams directly in plain text Markdown. Folio compiles equations and charts into scalable vector paths in the final PDF — razor-sharp at any zoom level, never pixelated raster images.

Plain Markdown Syntax
$$
\mathcal{L}_{\text{total}}(\theta) = \mathbb{E}_{x \sim p_{\text{data}}}\left[ -\log p_\theta(x) \right] + \beta \cdot D_{\text{KL}}\left( q_\phi(z|x) \,\parallel\, p(z) \right)
$$

Real Pages, Not Infinite Scrolls

Real pages, before you export.

See page breaks, headers, footers, tables, and diagrams exactly where they’ll land in the PDF.

01

Real pages, before you export.

See page breaks, headers, footers, tables, and diagrams exactly where they’ll land in the PDF. What you see on screen is what prints to paper.

02

Paste the Markdown. Get the document.

Use output from ChatGPT, Claude, or your own agents without rebuilding it in Word or Google Docs. Mermaid, LaTeX, tables, and code render directly.

03

Your files stay Markdown.

Keep them in Git, edit them anywhere, generate them with agents, and export locally on your Mac. 100% offline with zero cloud lock-in.

Common Questions

Frequently asked questions.

Is Folio really completely free?
Yes, 100% free forever. No account, no sign-up, no monthly fees, and zero subscriptions. Folio is open source under the MIT license and runs completely locally on your Mac. Download it and use it forever with zero paywalls.
Can I use output from ChatGPT, Claude, or AI coding agents?
Yes, absolutely. AI already gives you Markdown. Paste raw text directly into Folio, and it instantly renders into a polished, printable document with styled tables, syntax highlighting, Mermaid diagrams, and LaTeX math.
How does Folio handle page breaks compared to browsers?
Browsers format for endless vertical screens and guess page breaks when you hit Print — chopping table rows mid-cut or leaving headings stranded. Folio paginates continuously as you type, so you see real page boundaries, running headers, and margin boxes live before exporting.
Does Folio require an internet connection or send my documents anywhere?
Never. Folio is a 100% offline macOS desktop application. Your documents and exported PDFs stay strictly on your local disk. No subscriptions, no cloud accounts, and zero telemetry.
Are my documents locked into Folio?
No. Your files stay standard Markdown (.md). Keep them in Git, edit them anywhere in your favorite editor, generate them with agents, and export locally on your Mac.
