GPT-5: Chrome Extension in minutes - X NewsReader
GPT‑5 is here—and I used it with Cursor to vibe‑code a Chrome extension that turns your X/Twitter feed into a coherent, podcast‑style briefing. It clusters tweets and threads about breaking news, summarizes them with an LLM, and speaks with a professional ElevenLabs voice—all inside your browser.
What you’ll see:
End‑to‑end build in Cursor: manifest, content scripts, UI
GPT‑5 summarization for coherent, non‑robotic narration
ElevenLabs TTS for studio‑quality voice
Autoplay on Home timeline, options for keys/models/voices
Practical DOM scraping strategies for X/Twitter
Tech used:
GPT‑5 (OpenAI) for summarization
ElevenLabs for pro TTS
Chrome Extensions (MV3), JS, SpeechSynthesis fallback
Cursor for rapid AI‑assisted development
