Vellum: Your Personal Intelligence

# Vellum > Your personal AI assistant that remembers, learns, and takes real action — across every platform you use. Vellum is a personal intelligence platform. Unlike chatbots that reset every conversation, Vellum gives you a persistent AI assistant with deep memory, its own identity, and the ability to act autonomously on your behalf — sending emails, managing calendars, browsing the web, controlling your Mac, and more. It's not a chatbot. It's not an autocomplete engine. It's a separate entity that works for you, learns about you, and takes real actions in the real world. - It has tools, not just words — browse the web, read files, run code, send emails, manage calendars, control your Mac via accessibility APIs - It remembers you — across days, weeks, months. Preferences, projects, quirks. - It has its own identity — its own email, GitHub account, Slack handle. Recipients know they're talking to your assistant. - Your data stays yours — encrypted Vellum Cloud or on your own machine. Plain-text, exportable, deletable. ## Hosting Options - **Vellum Cloud** (default): Always-on sandboxed environment with managed API keys, per-account isolation, reachable from all channels. Sign up at vellum.ai and your assistant is provisioned in seconds. - **Local**: Desktop app on Mac, workspace at `~/.vellum/workspace/`. The runtime is open source. Bring your own Anthropic API key, stored in macOS Keychain. --- ## The Workspace Your assistant's identity, personality, and knowledge live in its workspace — a set of plain text files you can open, read, and edit. ### Directory Structure ``` ~/.vellum/workspace/ ├── IDENTITY.md # Name, emoji, nature, personality, role ├── SOUL.md # Principles and behavioral rules (constitution) ├── USER.md # Learned facts about you ├── NOW.md # Working scratchpad (tasks, context, goals) ├── config.json # Runtime configuration ├
