Spell check

As you type, Myne underlines words it does not recognise with a wavy red line. The check runs entirely offline against dictionaries bundled with the app, so your note text never leaves your device — no operating-system speller and no cloud service is involved. Right-click a flagged word for up to five spelling suggestions, add a word to a personal dictionary so it stops being flagged, or ignore it. The picker in settings lets you choose from 23 bundled languages, and a word counts as correct if it is valid in any of the languages you have turned on.

How spell check works

While you write, the checker flags each word it cannot find in your active dictionaries with a wavy red squiggle under it. The work happens in Myne’s Rust core, against dictionaries that ship inside the app — nothing is sent over the network, and the editor does not fall back to your operating system’s built-in speller. Spell check is on by default.

The squiggle is aware of Markdown, so it only checks the parts of a note where spelling matters. It skips code, frontmatter, the target of a wikilink, plain URLs, and #tags, and it checks ordinary prose, including a wikilink’s display text and alias. While your cursor is inside a word, the squiggle on that word is hidden, so a word you are still typing is not underlined mid-keystroke; the mark reappears once you move on.

A word is treated as correct if it is valid in any of the languages you have turned on, or if it is in your personal dictionary. There is no per-note language detection — the active languages are pooled together. That is what lets you drop English technical terms into a note written in another language without every English word being flagged.

The correction menu

To act on a flagged word, right-click it, or place your cursor inside it and press ⌘. (or Ctrl .). A small menu opens next to the word with up to five ranked suggestions at the top, followed by three actions that are always present:

• Add to dictionary adds the word to your personal dictionary so it is never flagged again in this vault. The personal dictionary is stored encrypted inside the vault.
• Ignore in this vault silences the squiggle on that word and remembers the choice, without asserting that the word is spelled correctly. Use it for a name or term you do not want in your dictionary but do not want underlined either.
• Ignore this session silences the word only until you close the app. It is held in memory and never written anywhere.

Choosing a suggestion replaces exactly the flagged word with a precise edit and leaves the rest of the line untouched. Nothing changes until you pick something — the menu is never an auto-correct. If the checker has no suggestions for the word, the menu shows No suggestions above the three actions. Right-clicking anywhere that is not over a squiggle gives you the normal operating-system menu instead.

Turning it on or off and choosing languages

Spell check lives in Settings → Editor. A Spell check toggle (On by default) turns the underlines on or off, with the helper line “Underline misspelled words as you type. Fully offline — your notes never leave the device.”

Below it, a searchable Languages picker lets you select one or more of the 23 bundled languages. Its helper line reads “A word is correct if it’s valid in any selected language — handy for mixing English terms into other-language notes.” The bundled set is: English (US), English (UK), Bulgarian, Catalan, German, Spanish, Persian, French, Hebrew, Croatian, Hungarian, Italian, Korean, Lithuanian, Latvian, Dutch, Polish, Portuguese, Romanian, Russian, Slovak, Slovenian, and Swedish. Turkish is not yet available.

Dictionaries are loaded only when a language is active, and they are bundled with the app — there is no language pack to download at any point. Adding more languages widens what counts as correct rather than narrowing it, because the languages are pooled.

Limits

The checker is fully local. There is no network call, and the operating system’s own speller and any cloud speller are never used — the decrypted text of your note stays inside the Rust core, which is the same posture as full-text search. Myne today runs entirely on your device; nothing leaves it.

Words you add to your personal dictionary and words you ignore for the whole vault are stored encrypted at rest, inside the vault, and are held in memory only while the vault is unlocked; they are cleared from memory when you lock. A word you ignore for the session only is kept in memory and is never written to disk. Because dictionaries ship inside the app and are never fetched at runtime, the language you write in is not revealed by a download. None of this is a security feature of the note itself — it is about keeping the speller from leaking your text. How the note is protected is covered in How Myne protects your notes.
