Ship It

Tight scope, real impact

One sharp user, a scope you can finish, and a working demo by Sunday. Small surface, outsized impact.

🎙️

WhatsApp🟢 EasyVoice AI

English coach in WhatsApp

Open WhatsApp, speak for 5–10 minutes, and get better at English. Send a voice message, or just call it.

What to buildSend a voice message → the AI tells you what you pronounced right, what to fix, and how to say it better. Stretch goal: a WhatsApp call where the AI talks back and corrects you live as you chat.

Make it yoursNo app, no fear. It feels like texting a patient friend, not sitting an exam — and it fits into a 10-minute gap in your day.

📸

Product🟢 EasyVision

Photo → structured data

Snap a photo or screenshot of any document and get clean, structured data back.

What to buildImage in → a vision model pulls out the fields you care about → a tidy table or JSON you can use or export.

Make it yoursHandle the messy real stuff — handwriting, bills, regional-language forms, screenshots — not just clean PDFs.

📚

Product🟡 MediumEdtech

Learn-anything tutor

Tell it what you want to learn. It builds the roadmap, teaches you, and tests you — no dumping documents required.

What to buildSay a topic → it makes a roadmap, teaches concept by concept with text, images and a short video, then quizzes you (click an answer, see right/wrong). Upload your own notes and it builds a test from them.

Make it yoursIt teaches step by step and checks you really got it — a path, not a chatbot.

Frontier

Build on the 2026 frontier

Higher ceiling, higher risk. Build the thing that barely exists yet and show the room what's coming.

🧠

Product🔥 FrontierAmbitious

Personal context & intent engine

Connect your notes, calendar, email and LinkedIn — and it learns the context of every person you deal with.

What to buildPlug in a couple of sources → open a chat with someone and it already knows who they are, your history, and drafts a reply for you. Start with one surface and make it feel magic.

Make it yoursIt becomes your memory across the internet — it knows the 'why' behind each contact, so you never start cold.

🔌

Product🔥 FrontierAgents · MCP

Make your app agent-operable

Let an AI agent actually run an app — like a CRM that updates itself when you just ask.

What to buildPick one app (a CRM, a tool you use) and build the bridge an agent drives. MCP is one way; a simple action-API is another. Demo the agent doing a real task hands-free.

Make it yoursGive an agent a clean, safe way to do real work in an app — create records, call actions, move data — end to end.

Real-World

Build something people would pay for

Real users, real money. Go narrow, own one painful slice, and ship a product a team would actually buy.

🧩

Product🟡 MediumTeams

Team onboarding & access agent

Hire someone and the agent sets them up — access to every tool, the right context, the right role. They leave, it pulls it all back.

What to buildNew joiner + their role → the agent grants access across your tools, shares the docs/knowledge they need, and assigns ownership. On exit, it revokes everything. Start with 2–3 tools and one role.

Make it yoursOne agent handles the whole lifecycle by role — joining, the right context, ownership, and clean offboarding.

🎓

WhatsApp🟡 AmbitiousYour campus

Fresher recruiting in WhatsApp

A recruiter in WhatsApp — drop your resume and LinkedIn, and it tells you what fits and even applies for you.

What to buildSend resume PDF + LinkedIn → the agent reads your level and interests → suggests roles that genuinely fit → (stretch) auto-applies on Naukri and others. The richest one here — scope it tight.

Make it yoursBuilt for freshers — it reads your level, guides you, and acts for you, instead of dumping a list of jobs.

How to win

Don't rebuild an app. Build something cooler.

Pick a person, not a market

Build for one real user — a shopkeeper, a student, a teammate. Specific always wins.

Working beats fancy

A rough thing that actually works beats a pretty thing that doesn't. Demo the real flow.

Build the part that does the job

The AI doing the work is the product — not the dashboard around it.

Build in public

Post your progress as you go. It's how the judges — and the whole room — root for you.

Got your own idea? Even better. Run it through the same test — a real person who'd pay, and a version you can demo in two minutes.

That's a wrap — thanks for building.
