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.
OpenAI API key:
• Create an account at platform.openai.com
• Go to API keys in your account dashboard
• Create a new secret key
• Copy the key and paste it into the app’s API key setting
Tip: Treat your API key like a password.
Do not share it publicly.
Gemini API key:
• Open Google AI Studio (aistudio.google.com)
• Create an API key for the Gemini API
• Copy the key and paste it into the app’s API key setting
Tip: Keep your API key private
and rotate it if you suspect exposure.
With Writone, you can shape your words for global conversations, post with confidence, and reply with tone that fits the moment without sounding translated.
