Vellum
A personal AI assistant for your busywork
Vellum is a personal AI assistant designed to handle recurring work across files, tools, and communications. It maintains long-term memory of the user's preferences, contacts, and context, and can act autonomously within a configurable permissions system. The assistant runs locally on the user's machine or in an isolated cloud container, with credentials stored in a local keychain or managed vault rather than exposed to the model.
Core capabilities include email triage and drafting, calendar management, web browsing, document and slide creation, code writing, deep research, website monitoring, and background task execution. Built-in skills cover Google Workspace, Slack, Notion, and the local filesystem, with additional community plugins and custom skills available. Model selection is flexible, supporting OpenAI, Anthropic, Gemini, and open-weight models via Ollama. Access spans macOS, iOS, Android, web, voice, email, Telegram, Slack, and terminal, with shared memory and active tasks across surfaces.
Vellum is aimed at individuals and teams seeking an assistant that can operate across personal and professional workflows. The software is free to download and self-host on personal hardware, a VPS, or private cloud without platform fees. Managed cloud plans are subscription-based and tiered by compute size, storage, and bundled usage, with a custom plan option for tailored configurations.
