Writone - Reply Assistant

Writone helps you rewrite and reply on X/Twitter in the language and tone you want.



• Write in any language, then reshape your text into natural, tweet-ready writing.

• This is not a word-for-word translation.
• The app focuses on how people actually post on X/Twitter, producing clear, concise, and context-aware phrasing that feels natural in real conversations.


• Supports 15+ languages with automatic language detection.
• Manual input and output language selection is also available.

• Reply faster, with the right voice.
• Paste an existing post and generate multiple reply suggestions based on context.

• Adjust the tone using simple controls such as casual, professional, friendly, or witty until it sounds like something you would actually post.



Important: API key required (Gemini or OpenAI).



• This app requires you to add your own Gemini API key or OpenAI API key to enable AI rewriting, tone adjustment, and reply suggestions.

• Your API key is stored on-device only and is never uploaded to our servers.

Free tier note.



• A limited free tier may be available.
• It typically uses a fixed model and a single rewrite style.
• For consistent quality, better tone control, and full flexibility, we recommend using your own API key.



How to get an API key.
