What is Vellum?

Vellum is a no-code AI agent builder that turns plain English descriptions into fully functional, autonomous agents. Instead of wrestling with complex frameworks or writing endless configuration files, you simply describe what you need—and Vellum handles the rest. The result is a working agent you can run on a schedule, trigger via an API, or interact with through a clean user interface. It's automation you actually understand and control, without the usual setup overhead.

Who it's for

• Developers who want to prototype and deploy AI agents without spending hours on boilerplate code or YAML configuration.
• Product managers who need to automate recurring workflows—like scheduling, notifications, or data processing—without relying on engineering resources.
• Solopreneurs and small teams who want to build custom AI assistants that adapt to their personal routines, preferences, and working styles.

Key features

Natural language agent creation

Describe your task in plain English, and Vellum translates it into a working agent. No need to learn prompt engineering or agent frameworks—just say what you want, and the system handles the rest.

Flexible deployment options

Once your agent is built, you can run it on a schedule, trigger it via an API, or use it through a built-in UI. This makes Vellum suitable for both background automation and interactive use cases.

Memory and learning capabilities

Vellum agents can log observations, learn from patterns, and remember past interactions. The system captures preferences—like "TypeScript preferred, YAML avoided"—and adapts behavior over time, making agents smarter with each use.

Context-aware behavior

Agents understand when to act and when to pause. They can enforce rules like "no pings before 9am" or recognize that "silence = processing" and hold all notifications accordingly. This creates a more natural, respectful interaction model.
