  **Write better X replies. Faster. Every time.**
  
  ReplyGen is the Chrome extension that drafts smart, concise X/Twitter replies in one click — optimized for the platform's culture and 280-character limit.
  
  ### How It Works
  
  1. **Install** — Add ReplyGen to Chrome. No account needed. Start immediately.
  2. **Click Reply** — Open any tweet and click reply. ReplyGen's widget appears inline in the reply composer.
  3. **Generate & Insert** — Select your tone and reply style, generate a draft, then insert it into the reply box with one click.
  
  ### Why X Power Users Choose ReplyGen
  
  **Tweet-Length Optimized** — ReplyGen's AI is specifically tuned for X. Replies are concise, punchy, and fit naturally within 280 characters without you having to trim.
  
  **Context-Aware** — ReplyGen reads the tweet you're replying to and generates a response that directly addresses what was said. No generic filler phrases.
  
  **5 Tones, 6 Reply Styles** — Express exactly the right energy: Neutral, Curious, Assertive, Supportive, or Thoughtful. Choose Agreement, Contrarian, Question, Insight, Empathy, or Playful reply styles.
  
  **Contrarian Replies for Healthy Debate** — The Contrarian style generates respectful pushback that sparks discussion and drives engagement — without being inflammatory.
  
  **Lifetime Access — No Subscriptions** —  Pay once for Pro, use forever. Tokens never expire. Refill packs available at a nominal cost for 1,500 tokens when you need more.
  
  **Bring Your Own Gemini API Key** — Pro users can plug in their own Google Gemini API key. No tokens deducted. Unlimited generations at Google's API cost.
  
  **Privacy-First** — Tweet content is processed in-memory only. ReplyGen does not store tweet data on its servers.
  
  **Works on X.com and Twitter.com** — The extension detects reply composers on both domains automatically.
  
  
  ### Use Cases
  
  - Creators growing their X following through high-quality engagement
  - Journalists and commentators entering topic conversations
  - Founders building in public and responding to community feedback
  - Marketers managing brand X accounts
  - Anyone who wants to be consistently active on X without spending hours writing replies
