Who builds AI Chatbot UIs with VisuallyJs

Any product for designing automated conversational experiences is a diagramming app at its core. VisuallyJs is what AI startups and enterprise platform providers choose for a visualization layer that's embedded, branded, and production-ready.

Conversation Designers

Visual editors where UX designers map out complex dialogue flows, defining how the AI responds to user intent, handles edge cases, and maintains context across multiple turns.

LLM Orchestration & RAG Workflows

Dashboards for building Retrieval-Augmented Generation (RAG) pipelines, where document retrieval, prompt templates, and model calls are visualized as an interactive workflow.

Customer Support Automation

Tools for support teams to build and maintain automated resolution flows, combining traditional decision trees with modern AI reasoning to solve customer issues efficiently.

AI Agent Builders

Platforms that enable users to create autonomous agents by connecting specialized LLM nodes, tool-use blocks, and long-term memory components in a visual environment.

What VisuallyJs gives you out of the box

Conversational domain nodes

From simple message bubbles to complex LLM tool-calling nodes, VisuallyJs lets you build custom shapes for any AI component and reuse them across your flows.

Agentic workflow layout

Conversational flows can grow rapidly. VisuallyJs includes powerful layout engines that can automatically organize complex branching and loops into clean, readable diagrams.

Live inference visualization

Bind UI elements to your AI backend to visualize the path an agent takes through a graph during inference, helping with debugging and transparency.

Logic validation and testing

Attach validation logic to connections to ensure conversation paths are valid and all branches are covered before deploying to production.

Extensive plugin library

Accelerate development with 15+ pre-built plugins for common editor needs: miniviews, snaplines, undo/redo, automatic edge routing, and more.

Interactive prompt engineering

AI nodes require fine-tuning. VisuallyJs supports integrated property inspectors for editing system prompts, temperature, and tool definitions directly within the UI.

Framework-agnostic

VisuallyJs works with React, Angular, Vue, Svelte and TypeScript. Integrates cleanly into your existing application architecture without constraints - but offers a range of tightly integrated components to help you build professional applications for your target library with ease.
