Vellum

Personalized AI assistant with persistent memory and autonomous action-taking

Overview

What Vellum does

Vellum is a personalized AI assistant that goes beyond chatbots by combining three key elements: persistent identity with its own email address, persistent memory that learns preferences and context across years, and autonomous action-taking capabilities that handle routine business and personal workflows. Unlike generic AI chatbots, Vellum maintains continuity across conversations, understands your work style, and can independently complete tasks like sending emails, managing calendar events, updating CRMs, drafting documents, and managing expenses. The platform reaches you across multiple devices including macOS, iOS, web, Slack, Telegram, and terminal, with the same assistant instance maintaining context everywhere. Vellum respects privacy through permission-based controls that require explicit approval for sensitive actions, and offers open-source plugins for custom extensions or training on your own data.

What people use it for

  • Personal productivity automation across email and calendar
  • CRM updates and pipeline management
  • Expense report generation and management
  • Document drafting and content creation
  • Meeting scheduling and calendar coordination

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Vellum.

  • Pricing varies significantly by computational tier, making budget planning difficult
  • Requires explicit permission for sensitive actions, limiting autonomy
  • Self-hosting option may intimidate non-technical users
  • Learning curve to develop customizations with plugins
