| Description | CastReader is a text-to-speech reader available as browser extensions and mobile and desktop apps. It reads webpages, PDFs, Kindle books and AI chatbot answers aloud with synced highlighting. | HARPA AI is a Chrome/browser extension that layers a hybrid AI-plus-web-automation engine onto any web page, letting you access GPT, Claude, Gemini, DeepSeek, Perplexity and local Llama models with one shortcut. It's built for marketers, SEO specialists, writers, recruiters and developers who want to summarize videos and pages, draft emails, generate long-form articles, extract data and monitor sites without leaving the browser. What sets it apart is that it can actually read, navigate, click and extract from live pages and trigger Zapier/Make/n8n chains, while running locally and not logging your conversations. |
