What is Vellum?
Vellum is a personal AI assistant that you can customize and keep under your own control. It runs locally on your Mac or in the cloud, is reachable from iOS, Android, web, email, Telegram, Slack and terminal, and shares the same memory, tasks and schedules across all of them.
In practice, it can send emails, manage your calendar, browse the web, create slides, write code, run deep research, monitor websites and execute recurring background tasks. It connects to Google Workspace, Slack, Notion and your filesystem, and can be extended with plugins or custom skills. Actions with higher stakes, such as emailing new contacts or spending credits, require your approval until you mark them as trusted.
