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
Motion
Pros
- Combines six+ categories of work tools (tasks, projects, calendar, meetings, docs, search) in one app
- AI auto-prioritizes and reschedules tasks hundreds of times per day based on changing workloads
- AI project generation creates entire project plans from a description, reportedly saving 4 hours per project
- Meeting notetaker trained on 10K+ hours of proprietary data auto-generates action items and follow-ups
- Proactively warns about at-risk deadlines days or weeks in advance
Cons
- Pricing details are not publicly listed on the website, making cost comparison difficult
- No free tier — only a free trial, so ongoing use requires a paid subscription
- Broad feature scope means it may not match depth of dedicated tools in any single category (e.g., standalone project management or calendar apps)
- Heavy AI reliance may not suit teams that prefer full manual control over planning
Our Verdict
Both Arc and Motion are excellent choices with similar feature sets. Your decision should depend on your specific needs, pricing, and whether you need self-hosting capabilities.
