How is a Vellum assistant different from ChatGPT or Claude?

ChatGPT and Claude are primarily chat windows that act on explicit command with limited memory. Vellum is an autonomous assistant with long-term memory that can take actions across your files and tools, keeps personal data local by default, and lets you switch between OpenAI, Anthropic, Gemini or open-weight models via Ollama.

What can a Vellum assistant actually do?

It can send emails, manage your calendar, browse the web, create slides, write code, run deep research, monitor websites and execute recurring background tasks. Built-in skills cover Google Workspace, Slack, Notion and your filesystem, with community plugins and custom skills available.

Is there a free option?

Yes. It is free to download and run locally. Vellum Cloud subscriptions start at $30/month (Mighty), $100/month (Super) and $200/month (Ultra), with dedicated compute, storage and bundled credits.

How private is my data?

By default your assistant runs locally, so conversation history, memory and credentials stay on your machine and are not used to train models. Vellum is open-source, and on Vellum Cloud your assistant runs in an isolated container provisioned exclusively for you.

Can it act without asking me?

Vellum uses a fine-grained permission system. High-stakes actions such as emailing new contacts, modifying important files or spending credits require explicit approval until you mark them as trusted, so you retain control.

关于 Vellum

Long-term personal memory

A custom-built memory system that retains you, your people, preferences and work across every conversation, rather than resetting each session.

Skills and tool integrations

Connect Google Workspace, Slack, Notion, your filesystem and community plugins so the assistant can send emails, manage calendars, browse, create slides and run research.

Fine-grained permissions

Set permissions so sensitive actions like emailing new contacts or modifying key files require approval until you mark them trusted.

Model choice

Switch between OpenAI, Anthropic, Gemini or open-weight models via Ollama at any time, keeping you free of a single vendor lock-in.

Local-first privacy

Your assistant runs locally by default with open-source code you can inspect; Vellum Cloud offers an isolated container provisioned just for you.

Available everywhere

Native on Mac and available on iOS, Android, web, voice, email, Telegram, Slack and terminal, all sharing the same identity, memory and schedules.

Vellum is a personal AI assistant that you own and customize. It runs locally on your machine or in Vellum Cloud, remembers your context over time, connects to your tools and takes real actions like email, calendar, research and file work, with model choice across OpenAI, Anthropic, Gemini or local open weights via Ollama.

Vellum 的高影响力用例

Knowledge workers

Automate personal busywork

Professionals use Vellum to chase invoices, update CRMs, draft decks, schedule QBRs and surface churn risks, with memory carrying context between tasks.

Privacy-conscious users

Private everyday assistance

With fine-grained permissions and local-first storage, people can let an assistant handle calendars, travel, groceries and reminders without exposing sensitive data.

Small teams and founders

Run operational workflows

Teams can run recurring research, competitive monitoring and standup notes through an assistant that writes code, creates slides and browses the web.

Developers

Custom skills and model tinkering

Because model access is open, developers can experiment with OpenAI, Anthropic, Gemini or self-hosted models and extend behavior with custom skills and plugins.
