About This Tool
Interactive Form Logic Designer is a pioneering tool that fills a massive gap in PDF capabilities: creating active, responsive fields instead of flat, dead forms.
Through our visual canvas featuring "glowing glassmorphic nodes" (built on React Flow), form fields are represented as connected modules. You can drag links to define relationships: e.g., when a checkbox is checked ➜ enable a text input ➜ auto-calculate values and update a total field.
Once designed, the AcroJS engine compiles the logic into official Acrobat JavaScript and injects it into the '/AA' (Additional Actions) dictionaries of the AcroForm. The interactive behaviors are then executed natively inside any standard PDF reader.

Not at all. The injected scripts only run on-screen during form completion. When printing, the current state of fields is printed statically without any node visualization.
