HEY reimagines how email works. Swizero reimagines when email ends.
Two opinionated email tools that reject the status quo.
Two opinionated takes, one broken inbox
HEY
Full email reinvention
New email address required (@hey.com or custom domain). Screener, Imbox, Feed, Paper Trail. Deep philosophy about attention and permission. HEY does not try to fix your existing inbox. It replaces it entirely.
Swizero
Companion layer on existing Gmail
No new address needed. Finite session triage on top of the Gmail account you already have. AI ranks and surfaces a handful of cards, you clear them, email ends. Works alongside your current inbox without asking you to abandon it.
