Live Demo & Review of the Newest AI Browsers: Dia vs Comet

Two new “agentic” browsers just launched: Dia (from The Browser Company) and Comet (from Perplexity AI). Both promise to integrate AI directly into your daily workflow - from smarter search and summarization to voice commands, inbox triage, and even one-click purchases.

a16z partner Olivia Moore compares both tools head-to-head after a week of hands-on testing. She breaks down how these browsers work, where they shine, and how close we really are to the vision of a truly AI-native web experience.

She covers and compares:

- Chat assistants

- Basic search

- Advanced Search

- Personalization

- Workflows

- Multi-Tab Reasoning

- Connected actions

- Task Automation

- General agents

- Collaboration & Shared Workspaces
