About Vellum AI
Vellum is a personal AI assistant that keeps a long-term memory of the user's preferences and work and takes actions across the tools they already use. The New York company, founded in 2023, was previously known for an enterprise platform for building and evaluating LLM applications; its website now centers on the personal assistant.
The assistant can manage email and calendars, browse the web, write documents and slides, write code, monitor websites and run recurring background tasks. It runs natively on macOS and Linux and can be reached from iOS, Android, the web, voice, email, Telegram, Slack and the terminal. Users can choose models from OpenAI, Anthropic or Google, or open-weight models through Ollama. High-stakes actions require approval until the user marks them as trusted.
Vellum is open source and can be downloaded and self-hosted for free, with data kept on the user's machine by default. Hosted cloud plans run the assistant on a dedicated virtual computer, with monthly tiers based on compute, storage and included usage credits.
