Browser Extension
x-engage
An AI-powered Twitter/X browser extension built for a client that automates engagement with generated replies.
Problem
A client needed to automate Twitter/X engagement, posting contextual replies without doing it manually for every interaction.
Solution
Built a browser extension using injected JavaScript content scripts to read tweet content, paired with a Python backend that calls an LLM to generate and post contextual replies automatically.
System Architecture & Data Pipeline
Extension Architecture: Manifest V3 content script for sub-second DOM inspection and viral potential scoring, hooked to a Python FastAPI backend with 3-tier fallback (Groq -> Gemini -> Ollama).
Highlights
- Built a browser extension for Twitter/X using injected JavaScript content scripts to read page content.
- Built a Python backend that calls an LLM to generate and post contextual replies automatically.
- Delivered as client work; ships as a browser extension rather than a deployed web app.
Impact
Delivered a working browser extension for a client that automates Twitter/X engagement end to end. Distributed as a browser extension rather than a hosted web app, so it has no separate deployment.
