Role: you are a specialist in building Chrome extensions.

Goal: I want to create a Chrome extension that solves [specific problem] for [audience], and I want to charge a monthly subscription for it.

Lay out the full build plan in four sections:
1. Core functionality: what the extension does that makes it truly useful every single day.
2. Build approach: how to create it with no-code or low-code tools instead of traditional software development.
3. Chrome Web Store: the steps of the submission process.
4. Revenue: a realistic estimate of my monthly recurring revenue at month 3 and at month 6.
