🧠 Bilingual & AI Intelligence

TenderFlow bridges standard English commercial terminology with formal Hindi administrative procurement standards.

1. Purpose Library Engine

Transforms simple categories into legally sound administrative purpose statements:

flowchart LR
    C["Category: <b>fire_fighting</b>"] --> E["⚡ Purpose Mapping Engine"]
    E --> H1["🇮🇳 <b>Hindi:</b> 'अग्निशमन एवं आपातकालीन जल आपूर्ति कार्य हेतु आवश्यक सामग्री'"]
    E --> H2["🇬🇧 <b>English:</b> 'Materials required for fire fighting and emergency water supply'"]

Loading

2. Automated Transliteration Cache

English line items are automatically translated/transliterated and cached in IndexedDB for instantaneous future queries:

flowchart LR
    IN["Input: 'Fire Hose Nozzle 63mm'"] --> AI["🤖 Multi-LLM Transliteration"]
    AI --> OUT["Output: 'अग्निशमन होज नोज़ल 63 मि.मी.'"]
    OUT --> CACHE["💾 Saved to Master Dictionary"]
