Feature Comparison
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
Grammarly
Pros
- Works across many platforms including browsers, desktop apps, Slack, Google Docs, and Zendesk
- Generous free tier that covers basic grammar, spelling, and tone detection
- Strong privacy stance: does not sell user content or use it for ad targeting or third-party model training
- Enterprise plan includes data loss prevention and granular role permissions for large organizations
Cons
- Pro plan AI prompts are capped at 2,000, which may not be enough for heavy generative AI users
- Monthly Pro pricing ($30/month) is significantly more expensive than annual billing ($12/month)
- Free tier has very limited generative AI capabilities (only 100 prompts)
- Enterprise pricing is not transparent and requires contacting sales
Our Verdict
Both Arc and Grammarly are excellent choices with similar feature sets. Your decision should depend on your specific needs, pricing, and whether you need self-hosting capabilities.
