The Dictionary improves recognition of names, jargon, acronyms, and technical terms. It can also replace a spoken form with the exact text you want inserted.

## Add an entry

1. Open **Dictionary**.
2. Enter the word or phrase mrmr should listen for.
3. Optionally add the replacement that should appear in the final text.
4. Enable case sensitivity only when capitalization must match exactly.
5. Add the entry.

Examples:

| Spoken or recognized term | Replacement |
| --- | --- |
| `mr mr` | `mrmr` |
| `kubernetes` | Leave blank; use it only as recognition vocabulary |
| `acme cloud` | `ACME Cloud` |

Duplicate terms are not added. The app displays the current entry count and limit at the top of the page.

## Edit, search, and delete

Search checks both terms and replacements. Hover over an entry to edit or delete it. Keyboard users can press `E` to edit the hovered entry or `Backspace` to delete it.

## Bulk add

Open the Dictionary menu and choose **Bulk add**, or press `⌘` + `B`. Bulk add is useful when many specialist words do not require replacements.

## Import and export

Use the Dictionary menu to:

- **Import** a dictionary JSON file.
- **Export** the current entries to `mrmr-dictionary.json`.
- **Clear dictionary** after confirmation.

The menu displays shortcuts for these operations.

## Sync across devices

Dictionary entries are local by default. Enable **Sync across devices** from the Dictionary menu or the **Privacy** page to keep them synchronized through your mrmr account.

Disabling sync deletes the server copy while keeping local entries. Clearing the dictionary deletes the entries themselves.

## How entries are applied

Dictionary information helps speech recognition, informs polishing, and applies exact replacements after polishing. This layered approach helps preserve important spelling even when AI polish is enabled.
