DOZ vs Opera

DOZ is a Chrome extension that follows natural-language instructions for browsing websites and handling email. It can navigate pages, click controls, scroll, type text, press keys, search, and fill forms. Through Gmail and Outlook/Hotmail APIs, it can read, search, reply to, and compose messages. DOZ says it understands English and Arabic. Users can choose full automation, confirmation before actions, or plan-only mode. A step timeline displays screenshots captured before and after actions. Supported AI providers are DeepSeek and NVIDIA Nemotron, and the extension requires your own API key for one. The Free plan costs nothing, with third-party API charges your responsibility. DOZ says page content is processed in the browser and sent directly to the selected provider, while keys, settings, and email OAuth tokens are stored in Chrome storage. Installation uses a GitHub download and unpacked Chrome extension loading.

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.
