What you can build

OpenBook is general-purpose: anywhere an agent should reason, call tools, branch, and sometimes ask a human — these are good places to start.

Daily content radar

Pull from RSS, Reddit, and HN; an agent scores and ranks each item; email a formatted digest on a schedule.

AI support agent

A customer message triggers a workflow that looks up the order over HTTP, branches on the situation, and escalates risky cases to a human.

Outbound & follow-ups

Draft, personalize, and send email via the Resend plugin — with an approval step before anything goes out.

Multi-agent pipelines

Chain specialist agents — researcher → writer → editor — passing structured work between them.

Data enrichment

Fetch records over HTTP, have an agent classify/enrich them, and write the results back to your system.

Event-driven ops

Fire a workflow from a webhook or a named event like order.updated and run an agent-driven response.

Order operations

Look up, refund, or update orders through the HTTP action — with human approval on anything irreversible.

RAG over your docs

Ground an agent in your knowledge base with the RAG plugin and answer with citations.

Have a workflow in mind? Describe it to the AI builder and it builds the graph.
