AI productivity Chrome extension that injects web content — PDFs, sites, Canvas LMS courses — directly into ChatGPT, Claude, and Perplexity conversations.
What I did: Joined a stalled codebase and delivered 80 commits over 9 weeks. Built the full file upload system with parallel PDF processing, token-aware context building (Pro/Free tier limits enforced before injection), and rate-limit tracking for ChatGPT. Migrated core sidebar components to React 19.
Also contributed to the Vercel/Next.js backend: Stripe checkout, Neon PostgreSQL endpoints, and subscription enforcement.
