Fay

What is Fay?

Fay is a no-code platform for building, deploying, and managing AI agents and deterministic workflows. Its Architect co-builder accepts a plain-language description, then designs, configures, and deploys the requested automation. Agents can reason, decide, and act toward a goal, while workflows provide predictable sequences of actions, conditions, and logic. The two can be combined in the same operational process.

Agents and workflows can start from database changes, inbound messages, forms, webhooks, and other events. They connect with more than 100 tools and can be accessed from Slack, Microsoft Teams, email, and other existing team channels. Fay lists use cases across customer operations, employee onboarding, claims, finance, incident response, procurement, compliance, revenue operations, and supply chain.

3. Connect the business applications, data, communication channels, and triggers involved.
4. Test the agent and deterministic steps with real workflow data.
5. Deploy the automation, then manage access, audit activity, and results.

Frequently Asked Questions

Does Fay require coding?

No. Architect and the visual builder are intended for nontechnical teams using plain language.

What is the difference between an agent and a workflow?

An agent reasons and acts toward a goal; a workflow follows a deterministic sequence. Fay can embed either inside the other.
