Build agents with or without code. See every result before it goes out, and keep a human in the loop wherever it matters.
Illustration: Marvin Console running a customer email. The agent looked up the order and its delivery status, drafted a reply, and the reply now waits for a person to approve it.
Four steps from an idea to work that runs every day.
Your email, apps and AI models.
From a template, in plain words or in code.
Agents do the work, step by step.
Your team approves what matters.
You set the fixed steps. Agents handle the parts that need judgment. People decide what matters.
Diagram: a new email starts the workflow; an AI step understands the request; an agent decides to look up the order and check delivery; a person approves the reply; the reply is sent.
Every step, including the ones the agent chose, is recorded with its reason, so you can always see what happened and why.
Approve, edit, answer or take over at any step.
See emails, documents and data exactly as they will go out.
Inputs, outputs, costs and decisions, including each agent's own choices.
Use Marvin Gateway, or your own Anthropic, OpenAI or Google keys.
Separate data, keys and budgets for every client or team.
A typed SDK, test keys and webhooks. First run in minutes.
Ready-made templates you can adjust to the way your team works.
