Projects

Open-source AI projects built by Rudra Sarker — AI for social good from Bangladesh: water-quality testing, legal-tech automation, accessibility, mental health, and 3D education tools. Every project ships with a public GitHub repository.

Flagship projects

• JolSetu — AI water-quality testing — Point your phone camera at a 20-BDT arsenic test kit; computer vision (CIELAB colorimetry with white-reference normalization) reads the result and speaks guidance in Bangla. QR-stamped live tubewell map, active-learning risk model, offline safe-well routing. Built on 6,593 real wells from the Araihazar survey.

• AdalatAI — AI-assisted court workflow — Bangla-language legal-tech platform: case intake with verbatim statute quotes from bdlaws.minlaw.gov.bd, judgment draft assembly, judge console with full audit trail. Zero-invention guarantees enforced by automated statute-verbatim tests (4.7M+ pending cases motivated it). Live: https://rudra496.github.io/adalatai · Source: https://github.com/rudra496/adalatai
• Porichoy — DPP-in-a-Box — Turns a factory's messy Excel, ERP and paper records into buyer-ready EU Digital Product Passports (ESPR Art. 8), with Bangla+English header mapping, readiness scoring, QR passport publishing and a SHA-256 provenance chain. Local-first; powered by women DPP Data Stewards. Built through the NIC 3.0 Needle Challenge. Live: https://rudra496.github.io/porichoy · Source: https://github.com/rudra496/porichoy
• ScienceLab 3D — virtual science laboratory — Interactive 3D experiments in the browser (Three.js/WebGL) plus offline Android and desktop builds, so students without lab access can still learn practical science. v1.0.0, listed on the Extella app store. Live: https://sciencelab-two.vercel.app · Source: https://github.com/rudra496/sciencelab3d
• MindWell — mental-health support platform — Educational library covering 393 conditions, 20 non-diagnostic assessments (PHQ-9, GAD-7, PCL-5, AUDIT, CAGE), CBT/DBT/ACT education, pathways to verified psychologists.

• StealthHumanizer — AI text humanization — Open-source rewriting service: BART-based humanizer for short text, gemma3:4b for long, with an automatic AI-detector showing before/after probability. Self-hostable. Live: https://stealthhumanizer.vercel.app · Source: https://github.com/rudra496/StealthHumanizer
• CiteWarden — citation integrity forensics — Live-verifies DOIs, arXiv IDs, PubMed IDs, CFR sections and case law (464-case landmark database + forensic bounds checks) and flags fabricated citations. Built for LexHack 2026. Live: https://rudra496.github.io/citewarden · Source: https://github.com/rudra496/citewarden
