Editor's Take

Honest opinion from our review team

"

I found that Copilot in Outlook seamlessly integrated into my existing workflow, making it easy to draft emails and summarize long threads. However, I felt limited by its reliance on the Microsoft ecosystem. Shortwave, on the other hand, felt like a breath of fresh air. Its AI-powered inbox organization was impressive, and I appreciated the integrations with other productivity tools. However, the learning curve was steeper, and I missed some of the customization options available in traditional email clients.

Pricing Verdict & Cost Analysis

Copilot in Outlook's pricing is tied to the Microsoft 365 Copilot add-on license. This means you're paying for a suite of AI tools across Microsoft's applications, which can be valuable if you use them all. However, it may be a less cost-effective option if you're only interested in email enhancements.

Shortwave operates on a freemium model, with a free plan that provides basic functionality and paid plans that unlock more advanced AI features and team collaboration capabilities. The paid plans are priced per seat per month, billed annually, making it potentially more expensive for larger teams but offering better value for smaller teams or individual users needing advanced features. The free tier is a great way to test the waters before committing to a paid subscription.
