</h2> <p>Using open-source AI is important for HostelAI because student information can be personal.<br> An open approach provides benefits such as:<br> Greater control over data<br> Possibility of running models locally<br> Ability to change or upgrade models<br> Lower running costs<br> More customization<br> Freedom to experiment with different AI models</p> <p>I built HostelAI for a college friend who lives in a hostel and often has to deal with scattered information such as timetables, assignments, notices, and hostel-related information.<br> Instead of searching through different PDFs, messages, and notes, HostelAI provides a simple AI-powered interface to find the required information.</p> <h2> How It Works </h2> <p>The student provides relevant college or hostel information.<br> HostelAI processes the information using AI.<br> The student can ask questions in natural language.<br> HostelAI provides a relevant answer based on the available information.</p> devchallenge weekendchallenge hf26challenge Aman Kumar Sat, 03 Oct 2026 10:58:09 +0000 https://dev.to/amankumar099/dev-challenge-49lp https://dev.to/amankumar099/dev-challenge-49lp <p><em>This is a submission for the <a href="https://dev.to/challenges/hacktoberfest-weekend-2026-10-01">Hacktoberfest Weekend Challenge: Build for a Friend</a></em></p> <h2> What I Built </h2> <h2> Demo </h2> <h2> Code </h2> <h2> How I Built It </h2> <h2> Why Does Open Innovation Matter?
