| Description | Dia is an AI-native browser from The Browser Company (creators of Arc) that integrates with tools like Slack, Notion, Calendar, Gmail, and GitHub. It generates morning briefs, pulls together information spread across tabs and apps, answers context-aware questions about on-screen content, and helps users prepare for meetings. Aimed at knowledge workers, it is currently available only on macOS. | 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. |
