I'm building Legatus - an AI agent platform you delegate real work to. Instead of another chatbot, we give people agents that act inside the tools they already use: drafting and sending email, scheduling meetings, updating docs, and getting things done across 20+ apps (Gmail, Google Calendar, Slack, Notion, GitHub, HubSpot and more). When there's no API, the agent opens a real browser and does it for you.
