💡 Inspiration & The Real-World Problem

In Bangladesh, informal social commerce (F-Commerce) and peer-to-peer digital transactions over bKash and Nagad account for over 80% of everyday online purchases. However, this ecosystem has created a ৳1,000+ Crore annual consumer trust deficit:

  1. The Advance Delivery Fee Trap: Fraudulent Facebook pages post viral deals with 70% discounts, collect ৳200–৳500 upfront for "courier charge," immediately block the victim, and clone a new disposable page the next day.
  2. Task & Recruitment Syndicates: University students lose thousands of BDT to Telegram/WhatsApp "online task" scams demanding VIP deposits.
  3. The Regulatory Lag: The Directorate of National Consumer Rights Protection (DNCRP / ১৬১২১) is reactive—it investigates complaints only after financial losses occur.

Citizens lacked an autonomous software-level shield to verify a seller, account, or deal before transferring a single Taka. ThokboNa AI (ঠকবোনা AI) was conceived to turn multi-agent AI and statutory jurisprudence into an everyday pocket defense for 170 million citizens.


🛡️ What It Does

ThokboNa AI is an autonomous, production-grade B2C AI platform built on three pillars:

  • 1. G2-Style Universal Inspector: Consumers paste suspicious social links, mobile wallet accounts, or upload up to 5 transaction screenshots. The system performs client-side canvas compression, multi-modal OCR, and outputs a calibrated 0–100 Threat Index, a 4-vector risk breakdown, and actionable safety checklists.

  • 2. Trustpilot-Style Commercial Registry & Watchlist: A curated directory of 15,000+ business entities in Bangladesh. Features authentic Registrar of Joint Stock Companies (RJSC) numbers, valid municipal Trade Licenses, and tracking of High Court liquidation orders (including landmark cases like Evaly Writ Petition 8242/2021 and Alesha Mart). Users can submit verified purchase reviews with receipt proof via an admin verification workflow.

  • 3. Perplexity-Style Legal Co-Pilot: A conversational legal advisor grounded in Bangladesh case law and the Consumer Rights Protection Act 2009 (Sections 37, 40, 50). It answers consumer queries, cites judicial precedents, and auto-generates safe counter-offer messages to send to suspicious sellers.

  • 4. Janata Scam Radar & Live Watchdog Ticker: A crowdsourced community fraud ledger tracking over ৳13.5 Crore in documented losses with real-time "Confirm Scam" community verification.


⚙️ How It Was Built (Architecture)

  • Multi-Modal Vision & OCR Pipeline: Ingests multiple screenshots simultaneously, extracts fine-print terms, courier barcodes, and bKash transaction IDs.
  • In-Memory Statutory RAG Engine: Grounded directly against Bangladesh Supreme Court judgments, Ministry of Commerce digital commerce directives, and DNCRP statutory provisions without database latency.
  • Dual-Core AI Reasoning: Orchestrates Google Gemini Flash Lite for contextual inference alongside an offline, 100% deterministic heuristic algorithm that guarantees fraud interception even during network outages.
  • Full-Stack Execution: Built with Next.js 14 App Router, TypeScript, and Tailwind CSS. Backed by Supabase PostgreSQL with Row Level Security (RLS) and verified by a 14-suite automated Playwright E2E test harness.

🧗 Challenges Overcome

  • Informal Bengali & Banglish Contexts: Scammers in Bangladesh operate in colloquial Bengali, phonetic English (Banglish), and screenshots with compressed fonts. Engineering prompt scaffolds and OCR pre-processors to reliably parse transaction numbers without hallucinations was a critical breakthrough.
  • Deterministic Fallback Architecture: Because consumers often check transactions on slow mobile networks, the application had to run sub-second client-side evaluations if API connections degraded.

🏆 Accomplishments & Solo Engineering

  • 100% Solo Engineering: Conceived, architected, localized, tested, and deployed to production by a single undergraduate engineering student.
  • Zero Prototype Shortcuts: 15 pre-rendered static routes with sub-second page loads, accessible UI design tokens, and dual Bengali/English language localization.

🚀 What's Next & Market Scalability

  1. Courier Return Rate Mitigation: Integrating pre-dispatch verification APIs with logistics leaders (Steadfast, Pathao, RedX) to eliminate fake customer COD orders, saving merchants up to ৳30,000 monthly.
  2. "ThokboNa Verified" Merchant Seal: A dynamic trust badge for verified RJSC merchants to embed on their stores, boosting checkout conversion by 40%+.
  3. Omnichannel Chatbot Integration: Bringing ThokboNa AI to WhatsApp and Messenger for 1-click screenshot forwarding.
