TendBot is the AI work assistant for teams that run on email — drafts replies, tracks follow-ups, and preps meetings. Every action waits for human review before it happens. Nothing goes out without your team's say-so. How it works: TendBot connects to your team's email and calendar, learns how your organization works, and handles the coordination overhead. It drafts replies, tracks pending follow-ups, and delivers morning briefings so the team walks into every meeting prepared. Every action waits for review. What TendBot does: • Drafts emails in your team's voice • Tracks follow-ups across the organization and surfaces what needs attention • Prepares meeting briefings from past correspondence and notes • Learns contacts, preferences, and priorities over time • Works with your existing email and calendar — no rip-and-replace Built for professional services teams. TendBot is designed for organizations whose work revolves around client correspondence, meetings, and coordination across the team. Your team stays in control. TendBot never sends an email or takes an action without explicit human review. It's the AI assistant that always checks with a person first. Dedicated team email address. Each TendBot deployment gets a dedicated @tend.bot address (like alfred@tend.bot) that clients can CC or forward to. TendBot picks it up and gets to work — pending review. Privacy-first. Your team's data stays yours. TendBot integrates with your existing systems — no third-party storage, no data resale. Contact us at hello@tend.bot to learn more.
