The scheduling was wrong. The AI (if any) was generic. Nothing understood what it meant to track revision cycles, manage board exam prep, or sync with the way Indian students actually work.</p> <p>So I built one that does.</p> <h2> What Revisit does </h2> <ul> <li> <strong>Google Drive sync</strong> — your academic files, always accessible</li> <li> <strong>Google Calendar integration</strong> — your schedule, inside the app</li> <li> <strong>Aria</strong> — an AI assistant built specifically for student workflows, powered by Groq</li> <li> <strong>Revision tracking</strong> — know exactly what you've studied and what's overdue</li> <li> <strong>Freemium model</strong> — free to start, no credit card</li> </ul> <h2> The biggest challenge </h2> <p>Building an AI assistant that stays coherent over long conversations without hitting token limits on a mobile app. I had to design a custom context window management system from scratch to make Aria feel natural and useful even during extended sessions — not just a one-shot question-answerer.</p> <h2> Where we are </h2> <p>Beta users are live. Play Store launch is pending. The company (Cynocyte) and parent organization (Unendless) are fully set up with websites, social media, and brand identity.</p> <p>All bootstrapped. No funding. Building this alongside my board exams from Kolkata.</p> <p>🔗 App: <a href="https://getrevisit.vercel.app" rel="noopener noreferrer">https://getrevisit.vercel.app</a><br><br> 🏢 Company: <a href="https://cynocyte.vercel.app" rel="noopener noreferrer">https://cynocyte.vercel.app</a><br><br> 🌐 Parent org: <a href="https://unendless.vercel.app" rel="noopener noreferrer">https://unendless.vercel.app</a><br><br> 🐦 Twitter: <a class="mentioned-user" href="https://dev.to/theswarnadeep_">@theswarnadeep_</a> | @cynocyte</p> ai android productivity showdev
