## Dia Browser

Dia rethinks the browser as a workspace assistant rather than a window full of tabs. Instead of bolting a chatbot onto a page, it gives the assistant awareness of your broader context: open tabs, linked Google Workspace or Microsoft Teams content, plus connected tools such as Slack, Notion and GitHub. Practical examples include a Morning Brief that assembles your calendar, inbox and key links before the day starts, a 'Live Work' tab row that surfaces the places work is actually happening, and a Better Meetings mode that opens the right meeting page, agenda, notes and related docs with a countdown so you join on time.

The assistant is designed to produce artifacts rather than just answers. You can ask Dia to turn scattered context into a shareable report, or request a deck and receive real slides with headings, layout and flow that need no redesign. Splits let you place a meeting on one side and a document on the other, and Dia remembers layouts for recurring meetings or focus blocks. Tabs can be grouped automatically with meaningful names such as 'Design Review' or 'Q2 Planning' instead of an unreadable strip. Profiles keep work, freelance and personal browsing — and their AI context — separate, switchable with a swipe.

Privacy is treated as a product feature. Controls are explicit and user-facing: tracker blocking, ad blocking, memory on/off, personalised new chats, and sharing of content data, all toggleable. The company states that data is never sold or used to build ad profiles, that Sync is end-to-end encrypted, and that a separate 'Dia for Work' tier adds SSO and admin tooling for teams. Dia is available as a free download for macOS and Windows, with a release notes and changelog page tracking frequent updates.

**Pricing & Plans:** Free to download and use on macOS and Windows. The company also promotes a 'Dia for Work' offering aimed at teams, which adds enterprise controls such as SSO and admin tools; check the official site for current enterprise terms.

- **Morning Brief:** Starts the day with a consolidated view of your calendar, inbox and key links so you know what is coming before work begins.
- **Context-aware answers across tabs and apps:** Ask once and Dia searches open tabs along with connected Slack, Notion, Teams, GSuite and other tools to answer with full context.
- **Decks and reports from scattered context:** Requests for a deck or a summary come back as presentable slides and shareable reports rather than raw chat text.
- **Live Work tab bar:** Surfaces where work is actually happening, like a specific pull request or spec draft, so one click lands you in the right place.
- **Profiles and encryption controls:** Separate work, freelance and personal browsing contexts, with tracker/ad blocking toggles and end-to-end encrypted sync.

**Strengths:** AI is built into the browser's core workflow rather than added as a sidebar; Context spans tabs, email, calendars and connected work tools for genuinely useful answers; Outputs are artifacts — reports and slide decks — not just chat responses; Explicit, user-facing privacy toggles plus end-to-end encrypted sync

**Limitations:** Only available on macOS and Windows, with no Linux or mobile release at present; Deep integrations work best inside Google Workspace or Microsoft 365 environments; Heavy reliance on connected data may not suit strict compliance setups without the work tier

## Perplexity Comet

Comet is a standalone web browser built by Perplexity around an AI assistant. Instead of treating AI as a separate site you visit, Comet embeds it in the browsing experience, so the assistant already knows which page you are looking at and can act on it. You can ask about an article you are reading, have a long page summarized, or hand off a task and let the assistant carry it out.

The browser is pitched as a personal assistant that handles more than chat. It can research a topic, draft an email reply that reflects your schedule, build a small website, put together a study plan, compare how different outlets cover a story, or help with shopping. Because it lives in the browser, these tasks run against the real web rather than a sandboxed chat window.

Comet is available for Mac, Windows, iOS, and Android, and can be set as your default browser. It sits within Perplexity's freemium model: you can start free and unlock more advanced AI capability through paid subscription tiers. Privacy and safety controls are managed in the browser settings, and Perplexity publishes guidance on how browsing data is handled.

**Pricing & Plans:** Freemium with paid options. Comet itself is free to download across Mac, Windows, iOS, and Android. Advanced AI capabilities and higher usage limits are tied to Perplexity's paid subscription tiers, which are billed separately.

- **AI that understands the page:** The assistant understands the page you are on, so you can ask follow-up questions and get answers grounded in what you are reading.
- **Agentic task execution:** Delegate tasks like drafting replies, creating study plans, or building a simple website, with the assistant taking actions for you.
- **Cross-platform availability:** Comet runs on Mac, Windows, iOS, and Android, so your browsing and your assistant follow you across devices.
- **Perplexity search built in:** Perplexity's answer engine is built in, so research and web search stay inside the browser instead of a separate tab.
- **Default browser and privacy controls:** Set Comet as your default browser and manage privacy and safety settings as you browse.

**Strengths:** The assistant sees the page you are on, so answers are grounded in your actual context; Handles real tasks like drafting email, building simple artifacts, and research, not just Q&A; Available across desktop and mobile platforms; Brings Perplexity's answer engine into the browser by default

**Limitations:** Requires switching from your current browser to get the full experience; Best features depend on a Perplexity account and subscription tier; Agentic automation is powerful but should be supervised on sensitive tasks
