AI study and writing tools platform
We designed and built an AI study platform for students from scratch, with eight tools covering paraphrasing, grammar, summaries, AI detection, plagiarism, citations and a study helper that turns uploaded documents into notes and quizzes. The React and Django product runs on AWS with single sign-on, subscription billing and usage metering.
Problem
The client wanted a single student-focused product combining the writing and study tools students otherwise use separately, delivered from scratch against a hard launch deadline.
Solution
The team designed the product in Figma, then built a React + Vite + Tailwind frontend and a Dockerised Django/PostgreSQL backend on AWS EC2 with S3 and CloudFront. It integrated an LLM chosen after cost and accuracy benchmarking, third-party AI-detection, plagiarism and humaniser APIs, Clerk sign-on with Google and Apple, and Stripe subscriptions with trials, webhooks, upgrades and USD/CAD pricing, plus per-feature word metering, prompt history and admin analytics. After launch it resolved in-app-browser sign-in blocks and page-speed issues and delivered a paid enhancement round.
