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. 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.

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.
