Claude sidebar + 5 Python scripts for $9, no subscription, CORS shadow DOM done right.

Strengths
  • •Manifest V3 + shadow DOM isolation shows real browser extension chops, not hand-wavy.
  • •Batch CSV processing and API cost optimization ($0.001/req with Haiku) demonstrates practical thinking.
  • •Owns the code, modify freely — removes friction that kills impulse purchases.
Weaknesses
  • •Sidebar summarization and text improvement are table-stakes features; Claude sidebar wrappers exist.
  • •No evidence of differentiation from existing sidebar tools (Perplexity sidebar, Copilot, etc.).
Target Audience

Knowledge workers, content creators, business automation enthusiasts

Post Description

Built two small tools this weekend that scratch my own itch:

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.

DoScript – Automation language with English-like syntax

DoScript trades shell terseness for English-like primitives (make folder, for_each file_in ...) plus safety features like a global --dry-run, typed errors (try/catch NetworkError) and rich file-loop metadata — handy for ad-hoc backups and file-sorting. The inclusion of a node-based visual IDE and a tiny installer suggests someone pushed this beyond a toy CLI, but the overall idea sits in a crowded space (PowerShell, Node-RED, AutoHotkey) so its appeal will be strongest for users who value human-readable syntax and a simple GUI.
