Quickstart
Build a workflow, connect a tool, and run it in the preview chat. Takes about five minutes.
This page builds a workflow that takes a chat message, calls a model, and replies. You then run it and read the record of each step.
Prerequisites
- A Flowblocks account at app.flowblocks.dev, or a local install.
- A key for at least one model provider: OpenAI, Anthropic, or xAI.
Start a workflow
On the home page, describe what you want in a sentence, for example "Answer support questions, and ask before issuing a refund". Flowblocks drafts a graph for you. If you would rather draw it yourself, open a blank canvas instead.
Every workflow begins with a Start step, which receives the chat message, and finishes at an End step, which returns the last output.
Add an Agent step
Pick Agent from the palette on the left. It appears on the canvas; drag it where you want it, then draw a connection from Start to the agent and from the agent to End.
Select the agent to open its settings on the right. Choose a provider and a model, and write the instructions the model should follow.
Connect a tool
In the agent's settings, pick a connector such as Gmail or Google Drive and approve access in the provider's window. Then choose which of its tools the agent may call.
Select only the tools this step needs. The model can call any tool you leave enabled.
Run it
Press Run to open the preview chat and send a message. The reply streams back as the graph runs.
Each run is saved. Open the Runs tab to see every step's input, output and timing.
Add an approval
Add a Human approval step before any action that needs sign-off. The run pauses there until someone approves or rejects it, then follows the matching path.
