Problem

As Korea approaches the 30-million foreign tourist milestone, Small Business Owners in tourist areas (restaurants, cafes) need menus in English, Chinese, Japanese, and Thai, but translation outsourcing costs $112-$225 per job and must be reordered with every menu change. Some businesses receive 3-5 foreign customer complaints per month due to poor translations (from direct Google Translate use).

Solution

Photograph or upload a Korean menu and the tool extracts text via OCR, then a food-specialized LLM translates it into 4 languages (English, Chinese, Japanese, Thai), automatically generating a print-ready PDF and QR web menu complete with allergen labels and price conversions.

Target: Restaurant and Cafe owners in designated tourist zones (annual revenue $75K-$375K), local merchant associations in tourist areas

Revenue Model: Per Transaction $7.50 (1 menu set, 4 languages). Monthly Subscription $22 (unlimited edits + QR menu hosting). 30% group discount for merchant associations.
