Bisonary - Writing Copilot for X

Write better on X in your own voice with AI suggestions, voice input, and composer tools.

Bisonary helps you write replies on X faster without leaving the timeline. The extension adds reply-writing actions directly under posts so you can quickly draft responses without switching tabs. Bisonary learns from your past replies on X and generates suggestions that match your writing style, helping you stay consistent while replying faster. Features • Suggest replies – generate reply ideas based on the post you are viewing, written in your style using examples from your past replies • Refine with voice – describe what you want the reply to say and Bisonary generates it using the context of the post and your writing style • Write with voice – speak what you want to say and Bisonary turns it into a clear, well-written reply (speech-to-text with grammar correction) Speak in your language You can speak in your native language and Bisonary converts it into clear, natural English replies. This helps non-native speakers participate more easily in conversations on X. How it works When you click a Bisonary action, the extension reads the visible post text on the page and sends it to your signed-in Bisonary account to generate reply suggestions. Suggestions are generated using the context of the post and examples from your past replies so the results match your writing style. If you use a voice action, the spoken instruction text is also sent to Bisonary to generate the reply. The extension does not automatically post replies to X. You always review the generated text and decide whether to use it. Privacy and permissions The extension reads visible post content on X pages only to generate reply suggestions. Your Bisonary session cookie is used solely to authenticate requests to app.bisonary.com. The extension does not expose X OAuth tokens and does not access private messages or other account data. The side panel helps you sign in, confirm extension status, and copy diagnostics when support is needed.
