The idea matters less than teams think and more than they act like. A judge does not reward novelty for its own sake; a judge rewards a real problem with a demonstrable solution. These ideas are chosen because each has a clear user and one genuinely hard part — the part that will impress if you solve it.

Agriculture and rural

  • Voice-first crop advisory in a regional language — hard part: evaluation without benchmarks. (Krishi Gyan, our Changethon winner, lived here.)
  • Mandi price alerts from noisy public data — hard part: data cleaning.
  • Pest identification from a phone photo with a confidence gate — hard part: refusing when unsure.

Education and campus

  • Syllabus-grounded study assistant with page citations — hard part: retrieval quality.
  • Lecture-to-notes with slide alignment — hard part: alignment.
  • Timetable and room-clash resolver for departments — hard part: constraints, not AI.
  • Notice-board reader for visually impaired students — hard part: skewed, handwritten text.
  • Placement-prep interviewer that grades against a rubric — hard part: consistent grading.

Health and wellbeing

  • Medication reminder that reads prescriptions — hard part: extraction accuracy and safety.
  • Symptom-to-department triage for a college clinic — hard part: knowing when to escalate to a human.
  • Mental-health check-in with strict escalation rules — hard part: the rules, not the chat.

Food, community and NGOs

  • Real-time surplus food matching between donors, NGOs and volunteers — hard part: logistics. (Annapurna won BYTEBATTLE with this.)
  • Volunteer shift scheduler with fairness constraints — hard part: fairness.
  • Donation receipt extraction and reporting for small NGOs — hard part: schema validation.

Small business

  • Invoice checker that validates totals and flags anomalies — hard part: deterministic scoring.
  • WhatsApp order-taker for a local shop — hard part: ambiguity in orders.
  • Product photo to catalogue listing with honest descriptions — hard part: not inventing specs.
  • Review summariser that cites the review it summarises — hard part: faithfulness.

Accessibility and civic

  • Sign-language-to-text for common phrases — hard part: dataset.
  • Form-filling assistant for government schemes — hard part: eligibility logic.
  • Bus arrival predictor from crowd-sourced pings — hard part: sparse data.
  • Complaint router for a municipal helpline — hard part: classification with accountability.

Developer tools

  • Codebase Q&A with citations to file and line — hard part: chunking code.
  • Dataset validator for fine-tuning files — hard part: catching template mismatches.
  • Prompt regression tester with golden outputs — hard part: judging semantic equality.

Pick the idea whose hard part you actually want to solve, then scope it down to one demo path. That is the project a judge remembers.

Forming a hackathon team: roles, skills and the mistake most teams make

At an Integral Startup Foundation hackathon Originally published at https://pranjulrathour.scult.in/blog/hackathon-team-roles-and-formation . That copy is the canonical version and gets updates first. Team TechVerse — Raman Shukla, Saksham Gupta and me — won three first prizes in 2025 not because we were the strongest coders in the room, but because we had stopped overlapping. When I mentor teams before a hackathon, formation is the first thing I fix. In a packed college auditorium The four roles Builder — owns the core feature and the demo path. Usually backend or the AI piece. Interface — owns what the judge sees: the front end, the flow, the seeded data. Storyteller — owns the problem statement, the pitch, the slides and the Q&A plan; also does user research in hour one. Integrator — keeps the pieces working together, manages the repo, runs the demo rehearsals. In a team of three, the builder or interface person takes this. The mistake Five friends who all write R...

Hello from Kanpur: what I build, and what I'll write about here

On the mic Originally published at https://dev.to/pranjulrathour/hello-from-kanpur-what-i-build-and-what-ill-write-about-here-f2j . That copy is the canonical version and gets updates first. I'm Pranjul Rathour, a GenAI engineer from Kanpur, India. This is the first post on this blog, so here is who is writing, what I have actually shipped, and what you can expect if you follow along. What I build Between February and July 2026, at Next Upgrad Web Solutions, I designed, built and shipped five production AI applications end to end, alone, and deployed all of them with Docker, CI and observability: RAG.NextUpgrad : a retrieval-augmented generation service with hybrid dense plus BM25 retrieval, cross-encoder reranking, streaming cited answers, and a confidence gate that refuses to call the model when the evidence is weak. It runs in about 220 MB of memory, inside a free 512 MB instance. FineTune Studio : fine-tune open models with QLoRA in a browser. Upload a dataset, validate ...

Carousel · 12 slides I built every part of tools.scult.in myself — 15 browser tools, 1,211 version-stamped prompts, a 50,000+ agent-skills library, a public MCP server, and 40 retro photo prompts where I'm the face in every example. All of it free. No signup, no ads, no upload step. Swipe through for what's inside and why I built it this way. Link in the last slide.
