Nodes. The building blocks.
Each node has one job — read inputs, transform them, hand structured outputs to the next. Five families, every method available on every plan. Fold them together and you have a workflow.
Closed Alpha. Categories below are live; the full thirty-nine methods are listed at plooi.ai/methods. Each tester gets every category from day one.

Anatomy of a node
Every node has the same four parts:
- Header — name, status pip, run button
- Inputs — typed ports on the left edge
- Outputs — typed ports on the right edge
- Inspector — config panel that opens on click (prompt, model, parameters, confidence threshold)

└─────────────────────────────────────────┘Wiring nodes
- Click an output port on the right of a node.
- Drag the line to an input port on the next node.
- Release. The wire stays until you delete it.
Types matter: a node that emits text can’t wire into a port that expects an image. Incompatible ports light up red on hover, so you see it before you let go.
Glass box. Every node carries its prompt, model, confidence and the source it folded in. Hover the confidence pip on any output to see the chain of evidence behind a claim.
Credits
Only AI nodes consume credits. Wiring, editing, opening the canvas and collaborating with your team are always free. Each run shows its credit cost before it spends.
The cost scales with three things:
- Node type — a 1-paragraph summarisation costs less than a long-form synthesis
- Model — frontier models cost more than fast / cheap ones
- Output length — every node has a token cap; longer outputs burn more credits
