Vellum

About Vellum

Vellum is a no-code platform that converts plain-English task descriptions into runnable AI agents. Users can run agents through a UI, trigger them via API, or schedule executions without needing setup or code.

Review

Vellum aims to make automation approachable for non-technical teams by asking follow-up questions, connecting to tools, and exposing each step so you can see what an agent will do. The platform emphasizes controllability and traceability with step previews and a run history that helps build trust before putting an agent on a schedule.

Key Features

• Create agents from plain-English instructions with interactive clarification questions.
• No-code workflow builder that produces agents runnable via UI, API triggers, or scheduled runs.
• Step preview and execution history so you can inspect what happened and why.
• State management to carry context between runs and support more complex workflows.
• Integrations and templates to connect multiple data sources and accelerate common automations.

Pricing and Value

At launch there are free options and promotional credits for early sign-ups; a 50-credit offer was available through the product announcement. Public pricing details beyond the introductory credits are limited, so teams should evaluate usage patterns and expected run volumes before committing. The value proposition is strongest for teams that need repeatable, visible automations without engineering overhead-if the agent can replace recurring manual steps, the platform can save time and reduce errors.

Pros

• Very accessible for non-developers - plain-English inputs and follow-up questioning lower the barrier to entry.
• Multiple execution modes (UI, API, schedule) provide flexibility for different workflows.
• Clear step previews and run history improve transparency and make it easier to trust automations.
• State support and integrations let agents work across sessions and with various tools.

Cons

• As a newly launched product, available templates and third-party integrations may be limited for some niches.
• Complex workflows can still require careful design and testing; non-technical users may need time to get consistent results.
• Long-term pricing and usage caps beyond introductory credits are not fully detailed on the public page.

Vellum is a strong fit for Sales, Marketing, Product Ops, and Customer Support teams that want to automate repeatable tasks without writing code. It works well for calendar management, meeting prep, content workflows, and multi-source automations where visibility into each step matters.
