Paste your legacy source
One file — COBOL, RPG, PowerBuilder, VB6, PL/SQL, or similar. No preprocessing or copybooks required to get started.
Business logic is extracted
Decision rules, validation conditions, status outcomes, and calculation logic are identified and traced back to their source paragraphs.
Unknowns are flagged as risks
Missing dependencies, unresolved calls, and ambiguous conditions are surfaced as risks — not silently guessed or omitted.
