Vesta

Vesta opens your markdown to read — calm typography, rendered Mermaid diagrams and KaTeX math, nothing between you and the words. When you do want to change something, one keystroke (⇧⌘E) flips to a live-preview editor, and one keystroke flips back. Point it at a single file or a whole vault.

• The reader is free. All of it — rendering, live reload, Quick Look, find-in-page, print & PDF export, fillable templates, and the editor. On Mac, iPhone, and iPad.
• Pro is $29.99, once. Bear's yearly price, paid exactly once — one Universal Purchase for every platform: vault sidebar, full-text search, wiki-links and backlinks, transclusion, live queries, daily notes and quick capture. No subscription, ever.
• Founders' price at launch: $19.99. A thank-you window for the people who show up first. When it closes, Pro sells at its regular $29.99 — a step planned and published from day one.
• Private by architecture. No telemetry, no account, no server of ours. Vaults sync through your own iCloud and work entirely offline — the flame doesn't need a network.

Vesta shipped its pre-release life as Gloss — same app, same scars, truer name. Gloss lives on as our free VS Code reading-mode extension. The Mac and iOS apps are headed to the App Store: free downloads, with Pro as the one-time unlock.
