Pros & Cons
Arc
Pros
- Strong privacy stance — doesn't track sites visited, search queries, or sell data
- Spaces and Profiles allow clean separation of browsing contexts (work, personal, hobbies)
- Built-in integrations with 17+ tools eliminate the need for many browser extensions
- Free to use with no ads or paid tiers currently
- Split View enables side-by-side browsing without external tools
Cons
- Not available on Linux — only macOS and Windows are supported
- Revenue model is still unclear, creating uncertainty about long-term sustainability
- The company is shifting focus toward a new product called Dia, which may affect Arc's future development
- Requires account creation for syncing, unlike some privacy-focused browsers
Dia Browser
Pros
- AI is embedded directly in the browser, eliminating copy-paste between ChatGPT and your tabs
- Skills system allows community-created, reusable workflow shortcuts (fact-check, cite, flashcards)
- Tab mentioning (@tab) lets you pull context from any open tab into your AI query
- Split view supports up to three tabs simultaneously with AI connecting information across them
- Privacy-focused approach with user control over data sharing
Cons
- Only available on macOS 14+ with M1 chips or later — no Windows, Linux, or older Mac support
- No transparent pricing information — unclear if or when paid tiers will be introduced
- As a standalone browser, requires switching from your existing browser and migrating bookmarks/extensions
- Reliance on a new browser means potential compatibility issues with some websites or extensions
