FAQ

Everything you need to know before you write your first sentence with writetrim.

Still curious? Ask our team
How is writetrim different from a grammar checker?
Grammar checkers flag errors. writetrim rewrites — pick a word, a sentence or your whole document and choose the tone, length or clarity you want. Spelling is just the starting line.
Will the AI change my voice?
No. writetrim learns the rhythm of how you write and stays inside it. You get a tighter, sharper draft — not a generic AI rewrite that reads like everyone else on the internet.
How private is my writing?
Your drafts are encrypted end-to-end with AES-256. We never train models on your text, and a deleted document leaves no copy behind on our servers.
Which languages can I write in?
Twenty-plus, including Spanish, French, German, Portuguese, Arabic, Japanese and Korean — each tuned for native-grade flow rather than word-for-word translation.
Is there really a free plan?
Yes — free forever, with daily rewrites and core grammar. Upgrade to Monthly ($4.99) or Annual ($3.99/mo) when you need unlimited tone control and version history. Cancel in two clicks, any time.
Does it work inside the apps I already use?
Yes. The browser extension drops writetrim’s rewrite menu into Gmail, Google Docs, Notion, LinkedIn, Slack and every other text field on the web.
