Hey Product Hunt! 👋

I'm Piotr, and I built kayet because every editor I tried kept showing me things: toolbars, sidebars, tabs, status bars, badges. I wanted the opposite: open the app, see only my text, and start writing.

How it works

By default kayet hides everything except your text, including the title bar and traffic lights. Move the mouse to the top edge and the controls fade in. Start typing and they fade out again. The file tree and Markdown preview are there when you need them (⌘\, ⌘⇧P) and gone when you don't.

What's inside

✍️ Markdown done quietly: subtle syntax styling, a live side-by-side preview with scroll sync, lists that continue themselves, ⌘B / ⌘I, paste a URL over text to make a link, paste an image to save it next to your file

🧘 Zen mode: keeps the cursor line centered and dims everything except the current paragraph

🎤 Presentation mode: separate slides with `---` and present any Markdown file, with step-by-step reveal

📤 Export to a self-contained HTML page or a PDF

⌘ Keyboard-first: command palette (⌘K), fuzzy file finder (⌘P) and workspace-wide search (⌘⇧F)

🗂 Workspaces and tabs: point kayet at any folder, or open one from the terminal with `kayet .`

💻 Code editor mode with line numbers and syntax highlighting for code and config files

🎨 17 bundled themes (Catppuccin, Gruvbox, Nord, Rosé Pine, Tokyo Night, Solarized…) that follow macOS light/dark automatically, or your own in a small TOML file

🛟 Safe by default: crash recovery for unsaved changes, detection of files changed on disk, and an optional autosave

Built to be light

kayet is written in Rust (Tauri 2) with CodeMirror 6 and no heavy frontend framework. It opens in about a third of a second, and a benchmark script checks that it stays fast. It runs natively on Apple Silicon and Intel Macs and updates itself. There are no accounts, no cloud, no telemetry and no plugins. Your files are plain files on your disk.

Free and open source (Apache 2.0).

or install it via Homebrew:

I'd love to hear what you think.

What does your ideal writing setup look like, and what would make kayet fit into it? 🙏
