Instead of Vellum
Vellum alternatives
Vellum brings file reading, calendar management, email, code execution, and computer control into a personal AI assistant. It keeps preferences and context in its workspace across conversations, and custom skills can extend its capabilities. Its OAuth connections include Google services, GitHub, Notion, Outlook, and other tools; approval prompts and configurable trust rules give users a say over sensitive actions. Vellum runs on web, desktop, mobile, and extension platforms, with self-hosting also available, but it cannot respond offline because it needs an AI model provider.

The free plan includes initial tasks and pay-as-you-go credits, while paid plans start at $30 per month. That price, the internet requirement, or Vellum’s personal-assistant focus may not fit someone seeking shared team work or tools to build and coordinate agents. The alternatives below range from a ready-made assistant to business workflow platforms and developer frameworks. Compare whether you need an individual helper or team processes, and weigh integrations, model flexibility, deployment options, and the amount of agent-building work you want to take on.
