An AI Assistant that’s easy to setup, does your work 24/7, knows your preferences and gets better over time.
Vellum Assistant is a personal AI assistant that remembers information about users, learns their preferences, and takes actions across connected apps. It is intended for people who want an assistant that can manage conversations, unfinished work, and proactive notifications over time. The catalogue skills, hooks, instruction, and setting configure or extend how the assistant works.
This repository also configures its own agents. See what vellum-assistant tells them →
