A beautiful Gmail inbox vs your whole team’s stack.
Slashy is a genuinely good AI-native email client. But it works with Gmail only, lives in iMessage and Slack, and is built around one person’s inbox. this+that works across Gmail and Outlook, Teams, Slack, and Google Chat, turns every message into tracked, assignable team work, and runs the follow-through — for less per seat.
A polished single-inbox client vs a team-wide assistant
Slashy does real things well: AI drafts in your voice, an inline writing assistant, a self-improving memory that learns your tone and contacts, read tracking, and a fast keyboard-first client. It is already SOC 2 Type II certified. If you live entirely in Gmail and want a sharper personal inbox, it delivers. this+that is built for a different problem. It treats Gmail, Outlook, Teams, Slack, and Google Chat as one stream of incoming work, extracts the tasks and commitments buried in those messages, assigns them to the right teammate, and runs workflows that handle what comes next. Slashy supports Gmail only today (Outlook is “coming soon”) and is priced for individuals at $30 per seat. this+that starts at $24, and $20 per seat for teams. If your team is not all on Gmail, or you need work to leave one person’s head, that is the distinction that matters.
