In their own words
Auto Browser
Auto Browser is a free Chrome extension that uses an AI agent in the browser’s side panel. It reads a webpage’s accessibility tree and can click, type, scroll, navigate, fill forms, and handle research tasks described in plain English. Pages exposing WebMCP tools can let it use those tools instead of the page DOM. Supported providers include Chrome Built-in AI (Gemini Nano), Google Gemini, OpenRouter, and local OpenAI-compatible endpoints such as Ollama and LM Studio. You can change providers during a conversation without losing its history. Write actions require approval, arbitrary JavaScript prompts for approval, and banking, government, and healthcare origins are blocked by default. The extension is free to install at free; Google Gemini and OpenRouter charge per request using your API key. Chrome 126 or newer is required for basic use. Attachments can be images or audio up to 10 MB each.
Opera
Opera is a free web browser for Android, iOS, Linux, macOS, Windows, and the web, with extension support and cross-device sync. Tab Islands group related tabs for collapsing or expanding. Built-in tools include an ad blocker that can also block cryptocurrency-mining scripts, plus a free VPN with no data cap and three general locations. Opera AI can use open-tab context, generate images, summarize PDFs, and translate or summarize YouTube videos. ChatGPT and Gemini are available from the sidebar, and Opera says its AI tools do not require sign-up. The sidebar also offers WhatsApp, Slack, Discord, Messenger, and Telegram, while Music Player supports Apple Music, Spotify, YouTube Music, and Deezer. Users can set browsing data—including history, cookies, passwords, and autofill data—to clear on exit. Opera browser costs nothing. VPN Pro is separate: plans cost $4 per month billed $48 yearly, $5 per month billed $30 every six months, or $8 per month billed monthly.
