Poralekha Bondhu (পড়ালেখা বন্ধু — 'Study Friend') is a Bangla-first AI study companion for Bangladesh's SSC & HSC students, powered by Meta's open-weight Muse Glimmer (30B), self-hosted by the builder on a free cloud GPU.

THE PROBLEM: Millions of students in Bangladesh study every subject in Bangla, but quality help is scarce and expensive, and mainstream AI study tools are English-first generic chatbots that don't speak the student's language — literally or culturally. A student in a village in Mymensingh stuck on a fraction problem at 10 pm has nowhere to turn. Poralekha Bondhu is built for exactly that student — by one: a higher-secondary student in Bhaluka, Mymensingh, building solo and phone-only.

WHAT IT DOES: Tutor Q&A in simple Bangla with real-life examples; a practice-question maker (MCQ + short questions with answer key); a daily study plan ('Today's Plan'); learn-from-a-photo explanations; and a built-in motivational story with voice. The UI ships in 16 languages (117 translation keys, full RTL for Arabic/Urdu) plus an open 'any other language' AI mode.

TECHNICAL: A single-file web app (~700 KB) that runs in any phone browser — no install, no app store — with streaming chat against an OpenAI-compatible endpoint and the model's thinking traces hidden for clean answers. Built, tested and deployed entirely from a Redmi Note 12 during the hackathon (26 Oct – 4 Nov 2026).

Built for the Meta Global AI Developer Hackathon, Indie Dev Track (solo), theme: Build for Your World.
