| Description | Perplexity Comet is a Chromium-based web browser that embeds Perplexity's AI agent directly in the sidebar, where it stays aware of the active tab and holds context throughout a browsing session. The agent can perform tasks like summarizing articles, drafting emails, and completing purchases, blending Perplexity's answer-engine search into the browsing experience. It runs on the web plus iOS and Android, and became free for all users in October 2025. | 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. |
