Six places you write English every day

Teams · team lead

Replying to a teammate in Teams

One line takes forever. Too blunt sounds like an order; too careful sounds like a form letter.

Select and press ⌥ twice to rewrite or change the tone — more formal in Mail, lighter in Teams or Slack.

GitHub · developer

PR descriptions and code review comments

The code is solid; the PR description reads like a grammar quiz. A review comment can sound like an accusation.

Checks GitHub, Linear, Jira, Cursor and VS Code. Terminals and code blocks are left alone. Editor acting up? ⌥⌥ Write, then ⌘↩ puts it back.

The client email that has to go out

It's late and the client is waiting. You've rewritten it three times and still worry one slip looks unprofessional.

Typos fixed on the spot, grammar flagged with the reason. ⌃⌥F fixes them all at once. In Mail, Outlook or Gmail, turn on “Use their email” so your reply answers what they said.

Cover letter · job seeker

The cover letter for the job you really want

The grammar is fine, but it reads stiff — and the recruiter can tell.

Stiff phrasing becomes what a native speaker would write. A free account gets the grammar fixes plus “Pro found N more” for clarity.

Gmail · support lead

Understand the customer, then answer well

You know every word but not how upset they are or what they want. Too light sounds dismissive; too heavy sounds defensive.

⌥⌥ explains what they mean and how they feel. ⌘E turns the panel into a reply box — your answer goes after their message and replaces nothing.

Charger stopped working — Gmail

Jordan R. · Customer

Hi, the charger I got stopped working after a week. Not thrilled, tbh. Can you send a replacement, or should I just return it?

RequestMildly unhappyNeeds a reply

They want a replacement or a return. Not thrilled is an understated way of saying quite unhappy.

Suggested reply 1: apologise, ship a replacement today, no return needed

Suggested reply 2: ask for a photo to confirm the fault

Press ⌘E to reply

Their message stays pinned above · collapsible

Sorry for the trouble. We'll send a replacement today, and there's no need to return the old one. I'll share the tracking number once it ships.

Draft · grad student

The first email to a professor

How do you open? How do you ask without being presumptuous? Half an hour in front of a blank email.

⌥⌥ then ⌘4: describe what you need and get a ready-to-send English draft, checked like everything else. Double-click any word for meaning and IPA.

FAQ

Questions

How is it different from Grammarly?

Same as-you-type checks in every app. WriteNative is for people whose first language isn't English: fixes explained in your language, messages explained and answered in one flow, start in your language when stuck, or pay once and run it on your Mac.

Is the free plan enough? What counts?

For occasional English, yes. Spelling needs no account. Free account: 50 grammar checks/day (1 per paragraph) and 20 AI actions (rewrite, tone, translate, Explain, reply, Draft: 1 each). Look up never counted. Resets midnight UTC.

Can't I just paste it into ChatGPT?

You can — but it's switch, copy, paste, paste back every time, and it often stops sounding like you. WriteNative fixes only what needs fixing, where you type, and tells you why.

Is it a translator?

No. It makes your own English correct and natural, and tells you why in your language. When stuck, you can start in your language.

Is it safe for work email and code?

Cloud checks are discarded afterwards, never stored or used for training. On-device + Lock to this Mac: nothing is sent.

Pro or On-device?

Everything unlimited on any number of Macs: Pro, $96/year ($8/mo) or $20/month. Pay once, run on your Mac even offline: On-device, $49 for up to 3 Macs, dictation included.

Is there a free trial? Can I get a refund?

The free account is the trial: no card, 50 grammar checks + 20 AI actions a day. Bought on our website? Write within 14 days for a full refund, no questions asked. App Store purchases follow Apple's terms.

Does dictation translate what I say?

No. It keeps the language you speak and only tidies it. To speak your language and get English, use the Translate tab's mic. Dictation is On-device and Pro.

Which apps does it work in?

Most Mac apps with a text field: Mail, Gmail, Outlook, Slack, Teams, Notion, GitHub, Cursor, VS Code, ChatGPT and more. Terminals and Google Docs are left alone. Requires macOS 14+.
