Check2Learn is a full-stack AI-powered education platform built for the modern classroom. Teachers create tasks, students submit answers in any format — typed, document, or handwritten — and AI evaluates responses instantly, identifies learning gaps, and re-presents content in alternative formats to reinforce understanding. The platform covers the complete classroom workflow: task and session management, real-time feedback, multi-format answer submission, performance history, intelligent content organisation, and in-platform messaging. Built with LangChain and LangGraph at its core, the AI layer is not a chatbot bolted onto a standard LMS — it is the evaluation engine that drives every student interaction. PieStack built the platform end-to-end, from system architecture through frontend, backend, AI workflow implementation, and cloud deployment.

L3AD is a full-scale digital manufacturing ecosystem built for a 3D printing service bureau in Reutlingen, Germany, where quoting was previously a slow, manual process involving file review, geometry checks, and cost estimation, often taking hours or days and resulting in lost orders. PieStack developed a custom AI-powered quoting platform trained on L3AD’s historical production data, with the main challenge being the structuring and cleaning of scattered legacy data rather than model development. After multiple iterations and accuracy testing, Phase 1 launched in early 2026, covering the complete workflow from file upload to order shipment, reducing manual effort by over 70% and generating standard quotes in just 11 seconds. The platform operates 24/7, enabling instant responses even outside business hours, with Phase 2 currently focused on SaaS automation and global factory synchronization.
