Dicto
A fast, offline desktop dictionary for Windows and Linux — native, instant, and faithful to every dictionary's design.
The problem
Most dictionary apps today are either web pages wrapped in Electron, online-only, or stuck with one bundled dictionary. Meanwhile, the richest dictionary content on the planet — MDX/MDD packs, the format behind GoldenDict and MDict — sits on disk waiting for a reader that treats it like a native app should.
Dicto is that reader.
What it looks like

What it does
- Instant search — suggestions appear as you type; results load in milliseconds.
- Faithful rendering — full HTML output with per-dictionary CSS, so each dictionary looks exactly as its author intended.
- Multi-dictionary — load as many MDX files as you like; enable, disable, and reorder them live, without restarting.
- Built-in downloads — pick dictionaries from Settings (WordNet 3.1, 155k+ English words, is included); everything is indexed automatically.
- Truly offline — after downloading dictionaries, nothing leaves your machine.

|---|---|
| MDX v2 (UTF-8, UTF-16) | Full support |
