Hackathons are intense. You have limited time, mixed skill levels on the team, and judges who care more about working demos and clear ideas than big promises.
This guide focuses on specific tools that help with real hackathon problems:
coming up with strong ideas
building something functional fast
showing clear visuals and workflows
presenting your project clearly
All tools below are explained in plain language, with practical use cases for beginners and non-technical founders.
1. Gemini (Idea & Strategy Brainstorming)

Description
Understanding the hackathon prompt and generating strong project ideas.
Gemini is useful at the very beginning of a hackathon, when teams are still confused about what to build. You can paste the full hackathon prompt, judging criteria, and even competitor ideas into Gemini. It helps you analyze everything together and suggest directions that judges are likely to care about.
Because Gemini can handle a large amount of text at once, it’s especially helpful when rules and constraints are long or complex.
Key Features
Accepts large inputs like prompts, rules, and competitor lists
Suggests project ideas based on constraints and judging criteria
Helps draft simple business models or value propositions
Useful for team discussions and quick feedback
Note on context size: Gemini supports very large inputs compared to most AI tools, which makes it better for reading full hackathon briefs at once.
Did you know? Gemini 3’s context window is much bigger than other AI models:
Gemini 3: 2 million tokens
GPT-5.1: 256k tokens
Claude 3.7 Opus: 1 million tokens
Use Cases in Hackathon
Turn a long prompt into 3–5 realistic project directions
Compare your idea with likely competitors
Draft a simple business model canvas before coding starts
2. Nano Banana Pro (Visuals & Branding)
Description
Making your project look polished without a designer.
Nano Banana Pro focuses on visual consistency. Instead of spending hours searching for images or fixing slide styles, your team can quickly generate logos, mockups, and visuals that all match.
This matters because judges often associate visual clarity with product maturity, even in early prototypes.
Key Features
Generates high-resolution visuals quickly
Keeps characters and styles consistent across images
Allows fast edits (text, lighting, outfits, layout)
Turns rough sketches into presentable scenes
Here is how Nano Banana Pro is different from old design tools:

Nano Banana Pro helps your team work fast and wow judges with great pictures. You can focus on your best idea and let AI do the design. That is how you win a hackathon.
3. Cursor (Fast Coding with Control)
Description
Turning ideas into real code quickly.
Cursor is an AI-powered code editor. You describe what you want in plain English, and it helps generate or modify the code. This is useful when your team wants a working demo, not just slides.
Cursor is more hands-on than no-code tools. It’s ideal when someone on the team wants control over logic or structure.
Cursor vs. Lovable (Quick Comparison)
Lovable: best for instant UI deployment with minimal setup
Cursor: better when you want to customize behavior or logic
Many teams switch between both depending on speed vs. control.
Key Features
Easy code editing based on feedback
Works well for rapid prototypes
Use Cases in Hackathon
Build a working frontend quickly
Adjust features based on judge or mentor feedback
Connect your frontend to a backend service (for example, Momen)
4. Momen (Backend Without Backend Complexity)
Description
Adding real backend functionality without heavy engineering.
Many hackathon projects fail because they only show mockups. Momen helps teams add real backend features—like user accounts, data storage, and APIs—without setting up servers.
For non-technical teams, this means you can still demo something that feels “real.”
Tip: Momen is full-stack web app builder. But you can choose it to build your hackathon backend. You will save hours and impress judges with a real, working app.
Key Features
Visual database builder for storing your project data.
User authentication that works out of the box.
Workflow automation with built-in AI agents.
API logic you can set up with a few clicks.
Seamless integration with vibe-coding tools for fast prototyping.
Momen’s Backend-as-a-Service cuts down setup time. You can add user login, data storage, and APIs in minutes. Traditional backend solutions take much longer and slow your team down. With Momen, you get more time to develop features and test your idea.
Use Cases in Hackathon
Add login and user data to your demo
Store and retrieve real project data
Connect AI-generated frontends to a working backend
Your team can use Momen to power any AI app. At an AI Bootcamp, teams built working prototypes fast. They created smart agents like a Sales Prospect Agent and an AirBnB Finder. One team even built Smooth Operator, an AI tool that helps people move by automating tasks like finding movers and negotiating prices. These projects show how Momen makes workflow automation easy.
If you want to win, connect your ideas to a real backend. Momen is the shortcut for hacker-founders who want to demo a full-stack AI app. Build your hackathon backend on Momen and show judges what your team can do.
