EchoX: AI Writer for X/Twitter, Clone Tone & Export Images

Built for X(Twitter) creators. Clone your tone, polish drafts, export long images. Boost engagement!

EchoX — AI that tweets in YOUR tone An AI writing assistant built specifically for X (Twitter) creators. Its core strength lies in learning your unique voice, rather than simply writing for you. ✨ Style Learning: The more you tweet on X, the better EchoX understands you. Click "Start Collecting" in the popup to import your past tweets; the AI ​​models your writing style across multiple dimensions, including length, vocabulary, and sentence structure. ✨ One-Click Polish: After drafting a tweet, click the purple button; EchoX refines the phrasing and pacing while preserving your original intent. A comparison window appears—showing your original text on the left and the AI-polished version on the right—and you can click "Try Another Version" if you aren't satisfied. ✨ Beautiful Long-Image Export: Click the screenshot button at the bottom right of a tweet to export a clean, white-background card image with a single click. You can choose to capture just the current tweet or stitch together an entire thread. Includes an EchoX watermark for easy sharing. ✨ BYOK (Bring Your Own Key): Freely switch between DeepSeek and OpenAI. Your API key is stored locally and never uploaded to a server. Switch providers or models simply by changing your key. 💁 First-time setup: Enter your API key in the popup, then click "Start Collecting" on X to let the AI ​​familiarize itself with your style. It works without samples, but the results are significantly better after collecting your data. 🔒 Privacy Commitment: EchoX collects no user data. API keys are stored locally in your browser (`chrome.storage.sync`), and style samples are stored locally (`chrome.storage.local`). AI requests are sent directly to your chosen provider's API without passing through any third parties. 🆕 New Features - 🪟 Before-and-After Comparison — Polished text no longer overwrites your draft immediately; a popup displays the original and the polished version side-by-side so you can decide whether to use it. - 🔁 Try Another Version — Not happy with the first draft? Click "Regenerate" without overwriting previously generated versions. - 🎯 Smart Sample Matching — No more purely random selection of historical samples; the tool now automatically selects the best matches based on your current draft's length and topic, resulting in a polished output that better reflects your voice. - 💾 Style Sample Export/Import — No need to worry about losing data when switching computers or reinstalling the extension; back up and restore everything with a single click using the JSON format. - 📐 Selectable Screenshot Scope — Configure the "Screenshot Scope" in the popup settings to choose between "Current Tweet Only" or "Full Thread"—you decide whether to capture a single post or stitch together a long image. 💡 Tip: After upgrading, we recommend checking the "Screenshot Scope" in the popup's advanced settings. The default is "Current Tweet Only," so if you previously preferred capturing the entire thread, you can switch it back.
