## Where they split

### Always-on hosting
Cowork runs tasks during a steered desktop session inside the Claude app. When you close the session or step away, the work pauses.
Vellum is fully managed cloud. No session to keep open, no laptop to babysit. Scheduled jobs and background tasks run in Vellum Cloud whether you are at your desk or asleep, and you wake up to work that already shipped.

### Works across every surface
Cowork lives in the Claude desktop app on Mac and Windows, with mobile entry through the Claude app on iOS and Android.
Vellum ships as a native Mac app, an iOS app, and a web app, with voice, email, Telegram, and Slack surfaces. Every surface shares one memory and identity, so you can switch from desktop to phone without losing a beat.

### Memory that compounds
Each Cowork task is a working session you steer to completion. The next task starts fresh, without inherited context.
Vellum builds a structured, persistent memory of your work, people, and patterns automatically. Every conversation makes the next one sharper, and that memory follows you across every surface.

### Data privacy
Cowork processes actions through Anthropic's infrastructure, with files accessed inside an Apple VZVirtualMachine sandbox on your machine. Audit logs and Compliance API are not yet captured.
Vellum is available as both Vellum Cloud and a native Mac app on your own machine, and Vellum never has access to your data on either path. Credentials live in an isolated vault the model never sees, so prompt injection cannot exfiltrate keys.

## Lingering questions

### When should I choose Vellum over Claude Cowork?
Choose Vellum if you want a persistent personal AI assistant that builds memory of your work and people over time, runs proactively in the background, and shows up across native Mac app, iOS, web app, voice, email, Telegram, and Slack with one shared memory. Vellum executes real actions through managed OAuth on 50+ services and runs scheduled work continuously in Vellum Cloud, not only during a steered session at your desk.

### When does Claude Cowork make more sense than Vellum?
Claude Cowork is Anthropic's agentic mode for knowledge work inside the Claude desktop app. If you already pay for Claude Pro, Max, Team, or Enterprise and primarily want to delegate self-contained desktop tasks like reformatting files, drafting reports from source documents, or organizing folders, Cowork covers that working-session pattern well.

### How much does Vellum and Claude Cowork cost?
Claude Cowork is included on every paid Claude plan: Pro at $20/mo, Max at $100 to $200/mo, Team at roughly $25 per seat per month, and Enterprise priced custom. Usage limits apply on each tier. Vellum offers a Free Base plan, plus Pro from $50/mo with pay-as-you-go credits, configurable compute and storage, and your assistant's own email and subdomain.

### How does memory work in Vellum vs Claude Cowork?
Vellum builds a structured, persistent memory of your work, people, and patterns automatically across every session, shared across native Mac app, iOS, web app, voice, email, Telegram, and Slack. Cowork operates as a working session: you describe a task, Claude executes it inside the session, and the next task starts fresh. There is no managed long-term memory of you across Cowork tasks.

### What integrations do Vellum and Claude Cowork support?
Vellum connects to 50+ services through managed OAuth with one-click setup and no API keys to handle, including Google Workspace, Slack, Notion, GitHub, Linear, X, and Telegram. Cowork has native connectors for Google Drive, Gmail, Slack, DocuSign, FactSet, Linear, Jira, and Chrome, plus custom MCP support for the broader ecosystem.

### Does Claude Cowork work on iPhone or only desktop?
Cowork is primarily a desktop product running inside the Claude desktop app on Mac and Windows, with mobile entry through the Claude app on iOS and Android. Vellum ships as a native Mac app, an iOS app, and a web app, with voice, email, Telegram, and Slack surfaces, all sharing the same memory.

### Where does my data live with Vellum vs Claude Cowork?
With Vellum, your data lives on Vellum Cloud with per-customer isolation, encryption at rest, configurable retention, and custom LLM credentials so model API keys stay under your control. Vellum never has access to your data on any deployment path, whether you run the native Mac app on your machine or use Vellum Cloud. With Cowork, files Claude accesses stay on your machine inside an Apple VZVirtualMachine sandbox, and Anthropic processes actions through its infrastructure under its enterprise data policies.

### Is Vellum or Claude Cowork better for non-technical users?
Both target non-technical users. Vellum is built for every human, with a native Mac app, an iOS app, and a web app, plus voice, email, Telegram, and Slack, all syncing one persistent memory. Cowork is built for knowledge workers who want to hand off desktop tasks during a working session inside the Claude desktop app. For ongoing personal AI work across surfaces, Vellum is the broader fit. For self-contained desktop deliverables, Cowork is a strong execution layer.

### Can I run Vellum on my own machine like Claude Cowork?
Yes. Vellum runs as a native Mac app on your own machine, with iOS, web app, voice, email, Telegram, and Slack surfaces in sync. If you want continuous 24/7 background work without keeping your laptop open, Vellum Cloud handles it on the Pro plan from $50/mo with pay-as-you-go credits, configurable compute and storage, and your assistant's own email and subdomain. Either path gives you the same assistant and identity.

### Can I use Vellum and Claude Cowork at the same time?
Yes. They serve different jobs. Some people use Vellum as their always-on personal assistant across surfaces and use Cowork when they want to hand a sandboxed desktop task to Claude for a single session. Most people consolidate on one over time once they see how Vellum's persistent memory and multi-surface presence cover the day-to-day.

### What's the difference between Vellum's memory and Claude Cowork's working sessions?
Vellum's memory is structured, persistent, and assistant-managed: it builds up an understanding of you across every conversation, surface, and action, and that memory is the same whether you reach the assistant from Mac, iOS, web app, voice, email, Telegram, or Slack. Cowork's working session is task-scoped: you define a task, steer it through to completion, and the session ends. Future tasks start fresh, without inherited context.
