Detailed Description

I am selling 2nd-brain.app, a fully functional SaaS application designed to be the perfect AI-powered study assistant for students.

The Problem: The market for Personal Knowledge Management (PKM) is filled with powerful but overly complex tools like Notion and Roam. Students, in particular, need a simple, intuitive tool to help them learn and organize information without a steep learning curve.

The Solution: 2nd-brain.app is the answer. It's a minimalist, web-based platform that provides the core features of a "second brain" without the bloat. It allows students to upload notes, get AI-powered summaries, generate flashcards and practice exams, and plan their study schedules effectively.

Traction & Validation: The concept is already proven. Since launching just last month, the app has organically attracted 63 active users, demonstrating a clear product-market fit.

Tech Stack: The application is built on a modern, scalable, and easy-to-manage tech stack:

  • Frontend: Next.js
  • Hosting: Vercel
  • Backend & Database: Supabase
  • APIs: 11labs (Text-to-Speech), Deepgram (Speech-to-Text)

The Opportunity for a New Owner: The foundation is solid and the product is validated. A new owner can immediately focus on growth and monetization. There is a huge opportunity to launch on Product Hunt, start content marketing to the student and productivity communities, and implement a freemium or subscription model to monetize the growing user base.
