Agentys vs ChatGPT vs Superhuman vs SaneBox: side-by-side comparison of AI email tools in 2026. Features, pricing, and which one actually handles your inbox.

A side-by-side comparison of four popular approaches to email: a dedicated AI assistant, a general-purpose LLM, a premium inbox client, and an automated filter. See which one actually handles your email — not just organizes it.

ChatGPT: powerful, but not an email tool

Superhuman: fast inbox, limited AI

SaneBox: great filter, zero writing

Each tool solves a different piece of the email puzzle. ChatGPT helps you write better, but adds manual steps. Superhuman helps you move faster, but you still do all the composing. SaneBox removes noise, but leaves every reply to you. We built Agentys because none of these tools addressed what ate most of our own email time: the writing itself. It connects directly to your inbox, learns your writing patterns, and drafts replies overnight. If your goal is to spend 10 minutes reviewing email instead of 90 minutes writing it, that is the difference that matters.
