About
Vellum is an autonomous desktop AI assistant designed to handle the repetitive, time-consuming tasks that fill your workday. It connects to your existing tools — email, Slack, local files, and more — and executes tasks on your behalf using computer-use capabilities you explicitly authorize. Whether it's triaging and responding to your inbox overnight, vibe-coding and deploying a habit tracker app, summarizing Slack threads and flagging action items, or ordering coffee for the office, Vellum turns natural-language instructions into real-world outcomes. At its core, Vellum learns your preferences and remembers your ongoing projects, improving over time the more it's used. It operates on a trust model: you start by granting limited access, and as Vellum proves itself, you can expand what it's allowed to do. Permissions are granular — approve once, for 10 minutes, or always — so you stay in control at every step. Vellum also lives inside Slack as a team-wide AI expert, able to answer questions from anyone you grant access, with full context across your organization's tools. For teams that need to ship internal tools quickly, Vellum can build and deploy lightweight web apps directly from a prompt. It's ideal for busy professionals, startup teams, and anyone looking to reclaim their time through intelligent, trustworthy automation.
Key Features
- Computer Use & Task Automation: Vellum can use your computer to execute real tasks — organizing files, running commands, managing apps — but only when you explicitly approve each action or grant standing permissions.
- Email Triage & Inbox Autopilot: Vellum reads, triages, unsubscribes, and responds to your email overnight so you wake up to a clean, action-ready inbox every morning.
- Slack Team Assistant: Deployed inside your Slack workspace, Vellum acts as an always-on expert that can answer questions, summarize threads, flag action items, and coordinate across all your team's tools.
- App Building & Deployment: Describe what you need — a habit tracker, an internal dashboard, a trip planner — and Vellum vibe-codes and deploys the app to a live URL with no manual coding required.
- Memory & Preference Learning: Vellum remembers your projects, preferences, and past instructions, becoming more effective and personalized the longer you use it — while your credentials never touch the model.
Use Cases
- Automatically triaging, unsubscribing, and responding to email overnight so professionals wake up to a clean inbox.
- Acting as a Slack-based team assistant that summarizes meeting threads, flags action items, and coordinates across tools.
- Building and deploying lightweight internal web apps from plain-language prompts without writing any code.
- Automating repetitive computer tasks — organizing files, running commands, managing workflows — with user-approved permissions.
- Handling day-to-day logistics like ordering office supplies or scheduling reminders so teams can focus on high-value work.
Pros
- Granular Permission Control: Approve actions once, for a time window, or always — you stay in full control of what Vellum can do, making it safe to expand its autonomy incrementally.
- Broad Tool Connectivity: Integrates with email, Slack, local files, spreadsheets, and more, giving it the cross-tool context needed to handle complex, multi-step workflows.
- Credential Privacy: Your credentials never touch the underlying AI model, keeping sensitive account access secure even as Vellum acts on your behalf.
- No-Code App Deployment: Enables non-developers to ship functional web apps from plain-language prompts, dramatically lowering the barrier to building internal tools.
Cons
- Early Access Limitations: Vellum is in early access, meaning some features may be incomplete, unstable, or unavailable to all users during the rollout phase.
- Requires Trust-Building Time: The trust-based permission model, while safe, means new users must manually approve actions frequently before the assistant can operate more autonomously.
- Desktop-Centric: Currently focused on desktop and Slack environments, which may limit its usefulness for users who primarily work on mobile or in other ecosystems.
Frequently Asked Questions
Is Vellum safe to use with my email and Slack accounts?
Yes. Vellum is designed with privacy in mind — your credentials never touch the AI model. You also control every action it takes through a granular permission system, allowing you to approve once, for a time window, or permanently.
How does Vellum's permission system work?
Before Vellum takes any action on your computer or accounts, it asks for approval. You can choose to allow the action once, for the next 10 minutes, or always. This lets you gradually expand what Vellum can do as it earns your trust.
Can Vellum build and deploy apps?
Yes. You can describe any lightweight web app — a habit tracker, dashboard, or trip planner — and Vellum will code it and deploy it to a live URL. No manual development is required.
How does Vellum work inside Slack?
Vellum can be deployed as a Slack bot across your workspace. Team members you grant access to can ask it questions, and it responds with full context from all connected tools — summarizing threads, flagging action items, and more.
Does Vellum get smarter over time?
Yes. Vellum learns your preferences, remembers your ongoing projects, and improves its suggestions and automations the more you interact with it — making it increasingly useful as a long-term AI assistant.
