Custom dictionary (spell check)
Stop the spell checker from flagging your brand names, products and jargon.
Stop the spell checker from flagging your brand names, products and jargon.
The reply editor checks your spelling as you write. The custom dictionary is the list of words it should never flag — your brand names, product names and industry jargon. Add a word once and it stops being underlined for everyone in your workspace.
How it works
As you type a reply, unfamiliar words get a red wavy underline. Adding a word to the dictionary tells the checker to stop flagging it — instantly, for your whole team. There are two ways to add words: from Settings, or straight from the reply editor.
One shared list. The dictionary is workspace-wide — a word anyone adds stops being flagged for your entire team, and it takes effect on the next check (about half a second later). No page refresh needed.
Add a word from Settings
Go to Settings → Dictionary (in the Team & rules section) to manage the full list.
Open Settings → Dictionary (under Team & rules).
Type the word in the Add a word (e.g. Lunadesk) field — a brand name, product, or piece of jargon.
Click Add (or press Enter). It appears in the Words list below.
That word is no longer flagged as a misspelling for anyone in your workspace.
To remove a word later, click the trash icon next to it and confirm. It may be flagged as a misspelling again afterwards.
Add a word from the reply editor
You don't have to open Settings — you can whitelist a word the moment the checker underlines it.
Unknown words get a red wavy underline.
This opens the spell-check popover.
The underline disappears and the word is saved for the whole workspace.
Only spelling underlines have this option. Grammar and style suggestions use a different-coloured underline and offer only fixes and Ignore — not Add to dictionary. That's expected: the dictionary is for misspellings, not grammar.
What the dictionary changes (and what it doesn't)
The custom dictionary does exactly one thing: it stops the spell checker from flagging your words as misspellings. It doesn't touch anything else.

Case doesn't matter. Add lunadesk and Lunadesk, LUNADESK and every other capitalisation is covered too. Words can be up to 60 characters, and duplicates are ignored automatically.
Good words to add
- ·Brand and product names — your company, your products, sub-brands.
- ·Industry jargon and acronyms — SKU, RMA, chargeback, dropship, and the terms your team uses daily.
- ·Names of people and places that come up often in your support conversations.
Troubleshooting
A word I added is still underlined
Does everyone share the dictionary?
Does it change AI replies, search or translation?
How do I remove a word?
Is it case-sensitive? Any limits?
Add your brand and product names once, and the reply editor stops second-guessing the words your team types all day.
