Overview

ByLearn is a complete, production-ready web application that empowers users with advanced AI tools for learning, coding, and content creation. Built with Next.js 15, React 19, and TypeScript, this platform combines academic mastery tools—like a real-time coding assistant and math solver—with powerful content integrity features for AI detection and humanization. It features a modern, responsive design and includes everything needed to run a SaaS business, from user authentication to credit-based tool access.

⚠️ Important: External API Costs Disclaimer

ByLearn requires multiple external API services to function. You will incur costs based on your usage of these services.

Required services and their typical billing models:

• OpenAI / Gemini / DeepSeek – Usage-based billing (per 1k tokens). These power the Coding Suite, Tutoring, and Research tools.
• Undetectable AI – Subscription/Credit-based for the AI Humanizer tool (rewriting text to bypass detectors).
• ZeroGPT – API-based billing for content verification and AI detection services.
• Supadata – Usage-based billing for advanced document parsing, PDF analysis, and data extraction.
• Clerk – Free tier available (up to 10,000 MAU). Production scale or advanced features may require a paid plan.
• Stripe – Transaction-based fee (typically 2.9% + $0.30) per successful tool/subscription purchase.
• MongoDB Atlas – Free tier available (512MB). Paid tiers required for large-scale data storage or high concurrency.

Note: The purchase price of ByLearn covers the source code ONLY. You are responsible for all ongoing API, hosting, and service subscription costs.

You are responsible for all costs associated with these external services. The purchase price of this application includes only the source code and does not include any API credits, service subscriptions, or usage fees. Before deploying this application, please review the pricing pages of all required services to understand the costs you will incur based on your expected usage volume.

While many services offer free tiers suitable for development and testing, production use will require paid plans. Ensure you have budgeted for ongoing API costs based on your expected user base and usage patterns.
