Campaign Requirement Extractor extracts structured campaign requirement fields from campaign request text. It returns campaign name, objective, channel, budget, deadline, missing fields, source text, and errors. It does not design campaign strategy, judge budget reasonableness, write marketing copy, recommend channels, publish, schedule, send messages, update systems, or take operational actions. The app is read-only, stateless, uses no external APIs, stores no data, and only processes the submitted text for the current request.
