Dia vs DOZ

Dia is a macOS web browser with an assistant for questions and requests about the current page, other tabs, selected text, and browsing history. The free plan includes profiles, tab groups, split view, picture-in-picture, ad and tracking blocking, and cross-device sync, but has no AI features. Better Answers costs $20 a month and adds AI answers and contextual chats. Better Days costs $100 a month and includes six times more usage than Better Answers, plus additional work features. AI usage is measured in Tasks, resets each billing cycle, and pauses at the limit unless the user buys additional usage. Extra usage is available in $20 credit blocks, which roll over for up to three months. Profiles can separate work, freelance, and personal tabs, logins, and AI contexts. Morning Brief gathers calendar, inbox, and key links; Skills let users save frequent requests for reuse. The plans page lists connections to Slack, Gmail, Notion, Microsoft Outlook, GitHub, Google Calendar, and Figma. Dia says it does not sell personal data or use browsing data to build ad profiles, and that Sync is end-to-end encrypted.

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.
