Plain Write
Write brilliantly. Keep your data.
Bring-your-own-key: Your OpenAI key stays with you. No subscription, no text scraping — just a lifetime license and the Chrome extension that writes with you everywhere.
Why Plain Write instead of Grammarly?
The same writing help — without the subscription trap and without routing your text through someone else's cloud.
No subscription
Pay once, use forever. No monthly Grammarly subscription that drains you year after year.
No data scraping
Your writing never goes to our servers. We don't store drafts and don't train any model on your writing.
100% privacy with a local API key
BYOK: You store your own OpenAI key in the extension. Requests go directly from your browser to the provider.

Install the extension
Download Plain Write from the Chrome Web Store and pin the icon to your toolbar.
- 02
Enter your own API key
Enter your OpenAI key in the popup. The key stays local in your browser — we never see it.

Write perfectly everywhere
Select text in Gmail, Docs, Notion, or LinkedIn — Plain Write improves tone and clarity right where you write.
One price. Forever.
A lifetime deal instead of a subscription trap — pay once and use Plain Write for good.
