Paid
Feature Comparison
Pros & Cons
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
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 Motion 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.
