the sovereign markdown editor




Built with Rust and vanilla JS. No Electron, no framework, no build step. A single binary that starts instantly.
Editorial, Midnight, Mono, Sepia — each hand-tuned. Or build your own with 6 color pickers.
Flowcharts, sequence diagrams, and math equations render live in the preview pane. No plugins, no config.
Open a folder, browse your .md files from the sidebar. Persists between sessions.
Ctrl+K to access every action. Fuzzy search, keyboard navigation, shortcut hints.
Zero telemetry. Zero cloud. No accounts. No subscriptions. Everything stored locally. You buy it, you own it. Forever.
Is Inkwell free?
Yes. The full editor is free forever: all themes, workspace, diagrams, math, templates, and version history. No account required. PDF and HTML export require a one-time $19 Pro license.
Does Inkwell work without internet?
Completely. Inkwell has no cloud component. It does not connect to any server during normal use. Your files stay on your machine.
What operating systems does Inkwell support?
Windows, macOS, and Linux. All three platforms ship from the same Tauri/Rust codebase. Install via winget, scoop, yay, or direct download.
How is Inkwell different from Obsidian?
Inkwell is a focused writing tool, not a knowledge management system. No plugins, no graph view, no configuration rabbit holes. Open it, write, close it.
How is Inkwell different from Typora?
Inkwell ships new features faster (v1.4 shipped March 2026 with custom themes, command palette, Typst-powered PDF export). Inkwell has a free tier. Typora uses inline preview; Inkwell uses split view. Both support Mermaid and math.
Does the Pro license expire?
Never. One payment, yours forever. Your license is a signed file on your machine. No server validation needed. If 4Worlds disappears tomorrow, Inkwell keeps working.
