Configure the agents that run your workflows.

Build workflows where you decide the steps, agents that choose their own, or both. Run them from Marvin Console, see every result before it goes anywhere, and keep a record of every step, including the ones an agent chose.

Workflows, agents and runs

Three ideas, and everything in Marvin builds on them.

Workflow
You decide the steps: their order, conditions and where people step in. The same input always takes the same path.
Agent
You set a goal, the tools it may use and its limits; the agent decides each next step. Put agents inside workflows wherever judgment helps.
Run
One execution of a workflow or an agent. Every run leaves a record that cannot be edited, with every step, including the ones an agent chose.

What an agent did, and why

  1. 1Read the customer's emailConfiguredTrigger: new email to support@
  2. 2Look up order 88213Agent choseWhy: the email mentions a late delivery for this order
  3. 3Check the shipping statusAgent choseWhy: the order shows shipped 9 days ago, past the promised 5
  4. 4Draft an apology with a voucherAgent choseWhy: policy allows a 10% voucher after 7 days' delay
  5. 5Review before sendingPersonWaiting for the support team

An illustrative run. Each step also records its inputs, outputs, model, cost and time.

The result, before it goes anywhere

How much freedom each step gets

Inside a workflow, you choose each step's mode. Keep what must never change fixed, and let agents work only where judgment helps.

Fixed

Deterministic steps: transforms, checks and API calls.

Integrations, data clean-up

Guided

A model call whose output must match a schema.

Extraction, classification, drafting

Bounded

An agent picks tools within call limits, budgets and approvals.

Research, triage, reconciliation

Open

An agent with a goal, tools and guardrails, in a conversation.

Assistants for staff and customers

People in the loop, built in

Any step, whether you configured it or an agent chose it, can hand work to a person. The run waits, for minutes or weeks, and continues with their answer.

Approve
Approve or reject with a comment, above an amount or before anything is sent, paid or changed.
Review and edit
See the result as it will be delivered, change it, then send it on.
Answer
When an agent is stuck or unsure, it asks a person instead of guessing.
Spot-check
Rate a sample of finished results to keep quality visible over time.
Take over
Step in and finish a step by hand; the run continues with your result.
Assigned, on time, on record
Tasks go to a person, role or team with a due time, reminders and escalation, in the Console or by email, and every response is recorded.

How it will work

Business teams and developers work on the same workflows, and nothing reaches production until it passes its tests.

  1. Connect

    Use Marvin Gateway or add your own model keys, and connect the systems your work lives in: APIs, MCP servers, email and apps.

  2. Build

    Start from a template, describe the work in plain words, or build it visually in Studio. Developers can use code and Git.

  3. Preview

    Try a draft on real examples, compare it with the live version, and activate it once its evaluations pass.

  4. Run and export

    Start runs from the Console, the API, a schedule, a webhook or an email. Approve where you asked to, and export the results.

Everything runs in Marvin Console

One web app for everyone involved: builders configure, operators run, approvers decide, and clients see their own work, each in their own workspace.

  • Run on demandStart any workflow from a simple form, attach files, and watch each step as it happens.
  • Preview before it goes liveTry changes on real examples and compare them with the live version, with no emails or payments sent.
  • Export anythingResults, run lists, audit trails and configuration, as PDF, Word, CSV or JSON.
  • One inbox for peopleApprovals, reviews and agents' questions in one place, with the context to act, whichever workflow or agent asked.

Built to run real work, not demos

The parts teams usually build themselves after the first prototype will be there from day one.

Runs that finish
Each step is saved as it completes, so a timeout, outage or deploy resumes the run instead of losing finished work.
People where you choose
Approve, review, answer or take over at any step. A run can wait days for a person without holding anything up.
A record of everything
Inputs, outputs, versions, costs and decisions are kept in an audit trail you can search and export.
Budgets per client
Set token and spending limits per workspace, so runs stop before they overspend.
Models your way
Use Marvin Gateway, with models from major providers and no keys to manage, or connect your own Anthropic, OpenAI or Google keys and pay providers directly.
One workspace per client
Each client's data, keys and configuration stay separate, which is what agencies need.

Connects to what you already use

Marvin reaches your models, systems and channels through open standards first, with ready-made connections for common apps to follow. All connection types.

Models
Through Marvin Gateway with no keys to manage, or with your own keys for Anthropic, OpenAI, Google and other providers. Choose the model per step.
Tools
Any HTTP API and any MCP server, so agents can read from and act in your own systems. Ready-made connections for apps such as Google Drive and Microsoft 365 are planned.
Starting runs
The API and TypeScript SDK, schedules, webhooks from other systems, and incoming email.
Where people work
Marvin Console and email at launch, on a phone or a desk; Slack and a chat widget are planned.

Built for everyone, with or without code

Business teams and developers work on the same workflows, each in the way that suits them.

No code needed

  • Start from a templateReady-made workflows for common work, adjusted to your team.
  • Describe it in plain languageMarvin drafts the workflow for you to review and change.
  • Build visuallySteps, people, tools and conditions in one editor.

Code when you want it

  • A code view in StudioEvery workflow is readable configuration you can edit directly.
  • Git and the marvin CLIKeep workflows in your repository, review changes and deploy them.
  • API and TypeScript SDKStart runs, read results and answer tasks from your own systems.

Who Marvin is for

Teams that know their work and want it done reliably, without building the platform themselves.

Agencies building agents for clients

Run every client in its own workspace with its own model access, budgets and audit trail, bill model usage through Marvin credits if you like, and reuse your best workflows across clients.

Operations teams with document-heavy work

Hand over customer emails, invoices, contracts or weekly reports without waiting for an engineering backlog, and keep people in charge of the decisions that matter. See use cases.
