PureBox is an AI-powered inbox assistant that connects to Gmail via Google OAuth and uses an LLM to sort emails into three tracks: Attention, Archive, and Trash. It personalizes suggestions from your first scan by learning from your own Gmail history — which senders you open, reply to, or ignore — without requiring any manual rule setup. Every suggestion includes a plain-language reason, and nothing is moved or deleted until the user explicitly approves it. PureBox operates on a freemium model where a free scan covers up to 1,000 emails, with Pro subscriptions available for ongoing use.
