Automate every conversation

AI at any step, on the model you pick

• Choose the model for each node, from Anthropic, OpenAI, or OpenRouter. Runs use your project's AI credits.
• Agent node: holds the conversation, calls your functions, webhooks, and MCP servers, and moves on when the task is done.
• AI decide: reads the conversation and picks the branch that matches what the customer wants.
• AI fields: write any message or value as a prompt, filled in at runtime with your variables.
• Agents can work with function tools, webhook tools, streamable HTTP MCP servers, 2,700+ apps, a remote sandbox (beta) with GitHub repositories, rich WhatsApp replies, and built-in tools.

Add a step, connect it, done

• Pick from 13 steps, drop them on the canvas, and connect them: Start, Send Text, Send Template, Send Interactive, Wait for Response, Decision, Webhook, App, AI Agent, Custom Function, Emit Event, Handoff, and Call Workflow.

Canvas or code. Same workflow.

• @kapso/workflows: write workflows in JavaScript or TypeScript instead of dragging nodes.
• Kapso CLI: pull workflows and functions into a repo, review changes in Git, and push them back.

Test before it talks to anyone

• Chat like a customer: send mock messages and see exactly what the workflow replies.
• See every step: flow events show which steps ran, in order, and which way each branch went.
• Know what AI costs: see tokens and spend for every agent and AI decision in the run.

Start from anywhere

• Inbound message: a customer messages one of your WhatsApp numbers.
• API call: your backend starts a run with variables and context.
• WhatsApp event: message and conversation events, like a failed send or an ended conversation.
• Project event: custom events from your backend, your agents, or other workflows.
