Hermes Builder
Describe the flow you want in plain English. Hermes builds it on your canvas — real nodes, connected and paused — and asks before it turns anything on.
Overview
Hermes Builder is a chat on the right side of the canvas. Instead of adding nodes and wiring them yourself, you tell Hermes what should happen and it creates the nodes, connects them and fills in what it can, using the accounts you already connected.
How to use
Open Hermes Builder
Open the workspace you want to build in, and click Hermes Builder on the canvas. The chat opens on the right.
Describe your flow
Write what you want and press Send. Be specific about where events come from, what to check or change, and where they should end up.
Look at what it built
Hermes creates the nodes on the canvas and tells you what it did. The canvas zooms in on the nodes it just created or changed. Open any of them to check its settings, and ask Hermes in the chat for changes.
Turn it on
When something needs your OK — activating the flow, or touching nodes that already existed — Hermes asks in the chat and shows Activate / Cancel or Yes / No. Nothing changes until you answer.
Writing effective prompts
The more specific your prompt, the better the result. Include:
- Where events come from (a webhook, Stripe, Gmail, a schedule…)
- What to check or filter
- Where they should go (your API, Slack, Discord, email, a sheet…)
- Any changes to the data on the way
Example prompts
Create a webhook that receives Stripe payment webhooks,
validates the payload with a schema, then delivers to my API
at https://api.example.com/payments.Create a webhook that validates with a schema requiring
type, data.object.id, and data.object.amount fields. Transform
the payload to extract just the amount and customer ID. Send it
to a Slack channel with a formatted message and to an
analytics webhook.Good to know
- Hermes builds in the workspace you have open. Each workspace has its own conversation, which stays if you close the chat or reload the page, until you close the browser tab.
- Check what it built before you turn it on: values it could not know, like a channel or a URL of yours, may need your real ones.
- Hermes uses your plan's credits: about $0.01 of AI each, from 1 to 40 per message. When they run out, the chat is disabled until they renew. See Hermes credits.
