HARPA AI Browser Agent

HARPA AI is a powerful browser extension that brings together leading large‑language models (OpenAI ChatGPT, GPT‑4o, Anthropic Claude 3.7, Google Gemini 2.5, Perplexity, DeepSeek, Meta Llama, etc.) with a hybrid automation engine. It lets you invoke AI on any web page, automate repetitive tasks, and extract or generate content directly in the browser.

  • YouTube Summarizer & Talk‑to‑Video – Extract key takeaways, jump to timestamps, and interact with video transcripts.
  • Gmail Assistant – Categorise, summarise, and draft replies in your own tone.
  • Writer & Style Mimic – Generate emails, tweets, LinkedIn posts, SEO‑optimised articles, CVs, poems, and more while mimicking your personal style.
