Vellum Personal Assistant

Vellum Personal Assistant is a privacy-focused personal AI assistant with an open-source harness that can be hosted by Vellum or self-hosted with your own model keys. It was aimed at people and teams who want AI to carry out multi-step tasks, not just answer questions. Vellum announced its Personal Assistant Platform will shut down on November 2, 2026. Cloud-hosted assistants will stop working, logins will end and data will be deleted. Self-hosted assistants keep working, and a “Teleport” feature moves cloud assistants to local. Export or teleport your assistant before that date. If you need something similar today, popular options include Cadet (community fork), ChatGPT, Claude. Lesson for users: always keep your own copies of important data when you rely on any AI service, because products can change owners or close with little notice.
