AI toolkit and logic simulator suite for engineering students
The Problem: Engineering students waste countless hours writing repetitive lab records, debugging broken circuits on breadboards, and cramming for exams. The Solution (EngineeringOS): Built by an EEE student and full-stack developer under the Nodexi studio, EngineeringOS is a complete, deployable SaaS toolkit designed to save engineering students hours of busywork. Core Features Included in the Sale: Client-Side Logic Simulator: A drag-and-drop canvas for building and testing digital logic circuits. Because it runs client-side, it costs the owner $0 in server fees, acting as a massive free retention loop to bring students back to the site daily. AI Lab Record Generator: Generates formatted lab records to save students hours of manual writing. Truth Table Calculator & Circuit Debugger: Solves boolean logic and helps troubleshoot real-world setups. The Monetization Strategy: The free tools (like the Logic Simulator) act as organic marketing to attract students. The high-value, AI-driven tools (Lab Records, Debugging) can easily be gated behind a $5/month student subscription plan. Why we are selling: My co-founder and I built the core architecture and validated the technical execution. We are developers, not marketers. We are looking to hand this off to an operator or investor who can run the marketing side and scale the student subscriptions. What you get: Full transfer of the GitHub repository. Transfer of the domain. A 1-hour technical handover call to explain the API architecture and token optimizations.
Next step: <p><strong>Immediate Distribution:</strong> Launch the free Logic Simulator directly into engineering subreddits (r/EngineeringStudents, r/ECE) and university Discord servers.</p><p><strong>Turn on Monetization:</strong> Connect Stripe to gate the "AI Lab Record Generator" and "Circuit Debugger" behind a $5/month or $15/semester student pass.</p><p><strong>Content Marketing:</strong> Create 15-second TikTok/Reels showing how EngineeringOS instantly solves complex truth tables or generates a 5-page lab record in seconds. The student virality for tools like this is massive.</p>

Asking price: $1,500 USD
What's included
Source code, All related design work
I will include a 1-hour technical handover call via Google Meet or Zoom. During this call, my co-founder and I will walk you through the codebase, explain the logic simulator's architecture, and show you exactly how the LLM API prompts are optimized to keep your server costs low.
Reason for selling
My co-founder and I are deep-in-the-weeds developers and architects, not marketers. We built EngineeringOS to solve a massive pain point we experienced firsthand as engineering students. The tech is fully built and validated, but we want to hand the keys over to someone who actually understands how to run a go-to-market strategy, build a community, and scale consumer subscriptions.
