Philosophy
Superhuman is built around the idea that with the right shortcuts, you can hit inbox zero in 30 minutes. Serif is built around the idea that you should not have to touch most of your inbox at all.
AI features
Superhuman has added AI features over time but they remain assistive. Serif is AI-first — triage and drafting are the product, not an add-on.
Pricing
Superhuman runs around $30/month. Serif starts free with a paid Pro tier. Several reviewers run both.
