Free AI workflow builder — design visual prompt chains and export them as portable JSON pipelines.
ClaudFlow is a free visual workflow builder for designing AI prompt chains as flowcharts. Drag and drop blocks onto a canvas, connect them to define data flow between LLM steps, and export your workflow as JSON. Five block types cover every workflow pattern — Input, AI Prompt, Condition, Transform, and Output — and pre-built examples get you started in seconds.
- Visual drag-and-drop workflow canvas with SVG connection lines
- Five block types: Input, AI Prompt, Condition, Transform, Output
- Pre-built example workflows: Blog Pipeline, Code Review, Data Analysis
- Export and import workflows as portable JSON files
