FAQ

Honest answers.

How is this different from ChatGPT or Google Translate?+
Translation gives you words. NativeTone gives you culture. It knows Reddit hates self-promotion, X rewards punchy 2-line takes, and Japanese X culture writes completely differently from English. And unlike ChatGPT, you see a word-level diff — not a rewrite you evaluate blind.
Does my original content get preserved?+
Always. NativeTone only changes tone, structure, and platform-specific formatting. Your facts, numbers, product name, and key message are never dropped or altered. The diff view makes this completely transparent.
Do I need to connect my social media accounts?+
No. NativeTone is a text polishing tool, not a publishing platform. Write, polish, copy, paste wherever you want. No OAuth, no account connections, no API permissions. Your accounts stay yours.
Can I use it for English-to-English rewriting?+
Yes — one of the most popular use cases. Native English speakers shift between platform voices: LinkedIn corporate → X founder voice, Reddit authentic style → Product Hunt launch copy. Same language, completely different expectations.
Which languages can I write my draft in?+
You can write in any language — NativeTone auto-detects your input. Output defaults to US English because our algorithm was built around how American developers, founders, and Redditors actually write. If you need to output in Japanese, Chinese, Portuguese (BR), German, Spanish (MX), Korean, or French, we'll translate the US English rewrite into your target language. The platform tone stays American; only the surface words change.
Does X Blue check (25,000 char) mode work?+
Yes, on the Maker plan. Toggle between standard 280-character mode and Blue check long-form mode. The AI adapts output style accordingly — punchy and short for standard, structured for long-form threads.
