Vellum
Personal AI assistant with long-term memory that acts across apps
What is Vellum?
Vellum is a personal AI assistant with its own identity, long-term memory and skills that carries out tasks across your email, calendar, files and work tools. It runs in an isolated Vellum Cloud container by default, or locally and self-hosted from its MIT-licensed runtime, and is reached from web, desktop and mobile apps as well as Telegram, Slack, email and voice. Hosting is free on the Base plan, usage is paid for in credits, and Pro packages bundle a larger machine, storage and monthly usage.
Vellum has a free plan. Paid plans start at $30 per month (Mighty). See every plan
Good for
- People who want one assistant that remembers them across devices and chat apps
- Handing off email triage, calendar work and recurring background tasks
- Users who want to inspect or self-host the assistant's open-source runtime
Worth knowing
- The Base plan is free to host, but model usage, web search and image generation are paid for in prepaid credits at $1 per credit.
- Included monthly usage does not roll over, and pay-as-you-go credits expire twelve months after purchase.
- The docs describe the Windows app as a dev build tied to Vellum's development environment, and no Linux desktop client is shipped.
- The iOS and Android apps are clients for a cloud assistant; they do not run a local assistant on the phone.
Key features
- Long-term memory
- The assistant keeps facts, preferences and people in a personal knowledge base and recalls them across conversations. On your own machine the workspace is plain-text files plus a SQLite database.
- Skills for your work tools
- Built-in skills and OAuth integrations cover Google Workspace, Outlook, Slack, Notion, Linear, GitHub, HubSpot, Asana and Todoist. More skills come from a catalog or are written yourself.
- Permission prompts
- Sensitive actions such as file access, shell commands or emailing a new contact show an Allow or Deny prompt with a risk badge until you create a trust rule for them.
- One assistant on every channel
- The same identity, memory and schedules are available from the web, Mac, Windows, iOS and Android apps, a CLI, Telegram, Slack, email, voice and phone calls.
- Computer and browser control
- The desktop app adds voice input and computer control, and a Chrome extension lets the assistant read open tabs, fill in forms and act on the page in front of you.
- Cloud, local or self-hosted
- Run it in Vellum Cloud, locally on a Mac or Windows PC, or self-hosted on a Linux host or your own Google Cloud project, bringing your own model API key.
