## Resumen

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.

## Precios y planes

Free to download and run locally. Vellum Cloud subscriptions start at $30/month (Mighty), $100/month (Super) and $200/month (Ultra), each with dedicated compute, storage and bundled credits. Credits are consumed by actions. The site also notes the Personal Assistant Platform is shutting down by December 13, 2026, with instructions to download your assistant.

## Funciones y capacidades clave

- **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.

## Casos de uso principales

- **Automate personal busywork (Knowledge workers):** Professionals use Vellum to chase invoices, update CRMs, draft decks, schedule QBRs and surface churn risks, with memory carrying context between tasks.
- **Private everyday assistance (Privacy-conscious users):** With fine-grained permissions and local-first storage, people can let an assistant handle calendars, travel, groceries and reminders without exposing sensitive data.
- **Run operational workflows (Small teams and founders):** Teams can run recurring research, competitive monitoring and standup notes through an assistant that writes code, creates slides and browses the web.
- **Custom skills and model tinkering (Developers):** Because model access is open, developers can experiment with OpenAI, Anthropic, Gemini or self-hosted models and extend behavior with custom skills and plugins.

## Fortalezas

- Runs locally by default with open-source code you can audit
- Genuine long-term memory that persists across every conversation
- Model-agnostic: OpenAI, Anthropic, Gemini or local open weights via Ollama
- Takes real actions across email, calendar, files and connected tools
- Fine-grained permissions keep high-stakes actions under your approval
- Accessible on Mac, iOS, Android, web, voice, email, Telegram, Slack and terminal

## Limitaciones

- The homepage banner states the Personal Assistant Platform is shutting down by December 13, 2026
- Proprietary cloud tiers at $30–$200 per month, and credit-based actions can add cost
- High-stakes actions require approval prompts until you mark them trusted, adding friction early on
- Mac-first native experience, so non-Apple users depend on web and chat surfaces
- Heavy tool integrations and skill setup take time to configure well

## Preguntas frecuentes

### 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.
