1. Chrome extension — injects an AI sidebar into any webpage. Alt+A to toggle. Summarize, ask questions about page content, improve selected text. Manifest V3, vanilla JS, shadow DOM for style isolation. Uses your own Anthropic API key directly from the background service worker (~$0.001/request with Haiku).
2. Python script pack — 5 scripts for common business tasks: lead enrichment with ICP scoring, cold email generation (3 variations), SEO content outlines, meeting notes summarizer, LinkedIn post writer. Plain Python, anthropic SDK, no framework. Batch mode on the CSV-heavy ones.
Both at $9 on Gumroad. Source code, you own it, modify freely.
Happy to answer questions about the Manifest V3 shadow DOM approach or the Claude API integration — had some interesting CORS issues to work through.
