OWL · web + macOS · v0.2.4
Owlet
A text and markdown reader for humans. Finder-like tree on the left, reading pane on the right; the same document viewable raw or rendered, editable in place, and exportable as a standalone styled HTML file.
The web app opens files you drop into the window (in-place saving needs Chrome/Edge; Safari and Firefox download the edited copy instead — the app tells you which happened). Everything runs in your browser: documents are never uploaded anywhere.
“Owlet.app is damaged and can’t be opened” — it isn’t. That is macOS’s wording for any unsigned app downloaded from a browser. Unzip, drag Owlet.app to Applications, then run this once in Terminal: xattr -dr com.apple.quarantine /Applications/Owlet.app — after that it opens normally.
What it does
- Open a file or a whole folder — or drag either into the window.
- Raw ↔ Rendered views of the same document; rendered is the point, raw is the source of truth.
- Edit the raw view (“editable — ⌘S saves”, Cancel discards); font zoom ⌘+/−/0; light and dark mode.
- Generate HTML: a self-contained, styled rendition (theme-aware) — a native save dialog on macOS, a download on the web.
- Document themes: five presets plus build-your-own, live-previewed on the open document; share between installs as JSON.
Privacy, plainly
- Zero network at runtime. No uploads, no telemetry, no fonts fetched — everything is bundled.
- No delete path, no silent overwrites. Replacing a file on export is the OS dialog’s explicit confirmation; saves are atomic on macOS.
- Refuses binary. A file that is not valid UTF-8 is declined, not garbled.
