EchoPost

Craft personalized X posts from your ideas.

EchoPost is a Chrome Extension that helps independent builders write posts in their own voice on X (Twitter). How it works 1) Analyze your style: - EchoPost scrapes your recent original tweets from x.com (based on your settings). - An LLM extracts a compact “Voice Style Fingerprint”. - The voice fingerprint is stored locally in your browser (chrome.storage.local). 2) Craft a new post: - Enter your Idea. - Choose an Output Type: - Hook Only (short & punchy) - Standard (balanced single tweet) - Deep Dive (2–3 segments) - EchoPost generates an authentic-sounding tweet that matches your style. 3) Use the result: - Copy & Open X (pre-fills the composer on x.com), or - Insert into composer (attempts to inject directly into the composer box). Output Type formats - Hook Only: 1–2 short sentences, no line breaks - Standard: one balanced tweet, optional single newline - Deep Dive: 2–3 newline-separated segments (no bullets), each as a complete mini-thought Privacy - No personal data collection. - Your API keys and analyzed voice profiles are stored locally in chrome.storage.local. - Scraping is limited to reading visible tweets on x.com when you click “Analyze Style”. Note - To use generation features, you must provide an API key for your chosen provider (OpenAI / Claude / Gemini). Install (Unpacked) - Build the extension and load the dist folder in chrome://extensions → Developer mode → Load unpacked.
