Vellum is a personal AI assistant that you own and shape over time. It keeps long-term memory of your life, people, preferences and work, then acts on that knowledge: sending email, managing your calendar, browsing the web, building slides, writing code, running deep research and monitoring websites. The software is open source and free to download, and it can run on your own machine. Vellum Cloud adds hosted compute with Mighty at $30 per month, Super at $100 per month and Ultra at $200 per month, plus pay-as-you-go credits for usage.

People who want an assistant with real memory and control over their data are the target audience. Busy founders, operators and sales leads can hand off follow-ups, invoice chasing and CRM updates, while privacy-minded individuals can keep conversation history and credentials on their own hardware. Developers and tinkerers can inspect the code, extend it with community plugins or write custom skills. Anyone nervous about autonomous software benefits from the permission system, which holds high-stakes actions such as emailing new contacts or spending credits until you mark them as trusted.

A typical day might include booking a lunch spot, drafting a board deck, enriching and scoring leads, chasing unpaid invoices or planning a marathon training schedule. Built-in skills cover Google Workspace, Slack, Notion and your filesystem, so the assistant can read a document, update a calendar entry and post a summary to a channel. Because the same identity, chats and schedules follow you across Mac, iOS, Android, web, voice, email, Telegram, Slack and terminal, a task started on your laptop can be checked from your phone. Recurring background jobs handle routine monitoring and reports.

Frequently asked

6 questions
How does Vellum remember things between conversations?
Memory is custom built to retain your life, people, preferences and work across every chat. It lives locally on your machine or in the cloud, and Vellum cannot access it unless you opt in.
Who gets the most value from Vellum?
Professionals who want delegated busywork handled, and privacy-focused users who want their data kept off third-party servers. Developers also benefit because the project is open source and extendable with skills and plugins.
Can Vellum take actions in other apps without my input?
Actions stay within the permissions you grant. Sending email to new contacts, modifying important files or spending credits requires approval until you mark those actions as trusted.
What does Vellum cost?
Downloading and self-hosting is free, with no platform fee. Vellum Cloud starts at $30 per month for Mighty, then $100 per month for Super and $200 per month for Ultra, with usage credits billed as you go.
What are the limits of the hosted plans?
Each cloud tier caps compute and storage, from a 1 vCPU, 10 GB setup on Mighty to 4 vCPU and 60 GB on Ultra. Usage beyond bundled credits is charged per use.
Where can I use my Vellum assistant?
Mac is the native platform, and it is also reachable on iOS, Android, the web, voice, email, Telegram, Slack and the terminal. You can switch between model providers, including open-weights models through Ollama.
