A tiny, beautiful text editor for macOS.

Open the file. Read it. Maybe change a line. Close it. No projects, no plugins, no sidebars — the editor disappears, and the content is all that's left.

The same note in Reader mode, rendered read-only: quote bar, live link, divider, real table and code block — one keystroke from the editor

Core values

Nothing more than you need.

Markdown, done lightly

Headings render larger, bold renders bold — while the syntax stays visible. Tilde doesn't hide Markdown; it makes Markdown easier to read.

Reader mode

One keystroke — ⌘⇧R — renders the whole document, tables and highlighted code blocks included, read-only. Toggle it from the title bar, like Safari's Reader.

Any plain text

.txt and .md first, but .json, .yaml, .toml, .xml, .csv, .log, .env and most UTF-based text files open too — all as plain text.

Quiet highlighting

In .json, .yaml, and .toml, keys get a gentle tint. Everything else is left exactly alone.

One file, one window

A true document-based Mac app: Open With, Autosave, Versions, Recent Documents, window tabs — all standard, none reinvented.

Fast, then silent

Launches fast, and idle CPU usage is effectively zero. No background work, no indexing, no polling. Ever.

Light and dark

Light, dark, or follow the system — using macOS semantic colors. There is no theme system to manage.

Everything you expect

Undo, Find & Replace, spell check, drag-and-drop, word wrap, and optional line numbers.

What Tilde won't do.

Tilde isn't a smaller IDE. If you need those things, Tilde is — intentionally — the wrong tool.

Your text stays yours.

Every document is processed locally, on your Mac.

Just open the file.
