Could you post a short status update for the client before noon?
Six places you write English every day
NativePen works the same way in each of them: select the text, press the shortcut, and keep writing.
Slack · project manager
Status updates that read clearly
You know what changed, but the message comes out long and stiff. Polish with the concise tone turns it into a short update the team can scan.
GitHub · backend developer
Commit messages and PR descriptions
Review threads are public and stay in the history. Select a PR description in Chrome or a commit message in VS Code and run Polish before you post.
Mail · sales
Follow-ups that stay polite
A follow-up that sounds pushy can cost you the deal. Write a one-line instruction, choose Draft, and edit the email it writes.
Amazon / Shopify · seller support
Answers in your customer's language
Customers write in many languages. Translate their message to read it, write your answer, then translate the answer back before you send it.
Notion · product docs
Specs the whole team can read
Dense paragraphs slow reviewers down. Select a section in Notion and Polish it into short, direct sentences.
LinkedIn · job seeker
A profile and messages that sound confident
Recruiters read your headline and messages quickly. Polish them with a formal tone before you post or reply.
Select, press, done
NativePen lives in your menu bar. You fix a sentence without switching to another window or browser tab.
Select the text
Highlight a sentence, a paragraph or a whole email in any Mac app.
Press the shortcut
Choose Translate, Polish or Draft from the small menu that appears.
Get the result in place
NativePen pastes the new text over your selection, or shows it in a popover so you can copy it.
What NativePen does
Three actions cover most of the writing you do in a workday. Each request costs one credit.
Translate
Translate a selection into 30+ languages. Line breaks, lists and other formatting stay as they were.
Polish
Fix grammar, spelling and punctuation, and set the tone to formal, casual or concise.
Draft
Describe what you need in a few words, such as "decline the meeting politely", and get a reply or message you can edit.
Works everywhere
Mail, Slack, Notion, Chrome, VS Code, Pages and any other app where you can select text.
Private by default
Your text is processed for each request and not stored by default. NativePen only sees the text you select and send.
Pay as you go
Buy a credit pack when you need one. There is no subscription, and every new account starts with 50 free credits.
Only the text you select is sent. Nothing is stored by default.
NativePen does not read your screen or watch what you type. It acts only when you press the shortcut.
You choose what is sent
The app sends the text you selected and the action you picked. Nothing else on your screen leaves your Mac.
Not stored by default
Each request is processed and the result is returned to you. NativePen does not keep a copy of your text.
Known models
Requests go to frontier models through OpenRouter: Qwen3 235B and DeepSeek V3 by default.
