Editor's Take

Honest opinion from our review team

"

I spent some time exploring both Copilot in Outlook and Superhuman. Copilot felt very natural within Outlook, like a helpful assistant that already knew my context. The email summarization was particularly useful. Superhuman, on the other hand, felt more like a command center for AI productivity. I appreciated the integrations with various apps, but it also felt like there was a steeper learning curve to fully leverage all the features. Ultimately, both tools are powerful, but Copilot felt more immediately useful for everyday Outlook tasks.

Pricing Verdict & Cost Analysis

Copilot in Outlook requires a Microsoft 365 Copilot add-on license, making it an additional expense on top of your existing Microsoft 365 subscription. The value here is in the deep integration and contextual awareness within Outlook, but it's only worthwhile if you heavily rely on Outlook. Superhuman offers a freemium model, with a free tier providing basic AI assistance. The Pro and Business plans offer more advanced features, but the monthly costs can add up, especially for larger teams. The value proposition for Superhuman is its versatility and broader range of AI tools, but you'll need to carefully evaluate if the features justify the subscription cost.
