this+that is an AI assistant for your inbox that unifies Gmail, Outlook, Slack, Teams and Google Chat into a single workspace and automates the work hiding inside your messages. AI reads your conversations to extract tasks, deadlines, and follow-ups into a self-building to-do list (called the DoBox), drafts replies, and runs AI-powered workflows that handle the repetitive parts of your day, such as forwarding invoices, digesting newsletters, auto-accepting low-stakes meeting invites, and more. With multi-account support across email and team chat, this+that lets professionals and small teams spend less time sorting communication and more time on the work that actually matters.
