Scrape paid or free articles from a Substack newsletter, saving both HTML and Markdown versions.

1. Clone the repository and enter the directory:

   git clone https://github.com/gitgithan/substack_scraper.git
   cd substack_scraper

2. (Recommended) Create and activate a virtual environment:

   python3 -m venv venv
   source venv/bin/activate

3. Install dependencies:

   pip install requests beautifulsoup4 lxml markdownify selenium
   

4. Install ChromeDriver and ensure it's in your PATH.

5. Edit substack_scraper.py:

   • Set BASE_URL to your newsletter's main URL (e.g., https://newsletter.eng-leadership.com)
   • Set SITEMAP_STRING to the sitemap path (e.g., /sitemap.xml)

• Scrape free articles:

  python substack_scraper.py
  

• Scrape paid articles (manual login required):

  python substack_scraper.py --paid
  

  This will launch a browser for you to log in manually (doesn't matter email OTP or with password). After solving captcha and logging in, press Enter in the terminal to continue scraping.

  Note: If paid content does not load correctly, you may need to increase the sleep duration in the script (see sleep() in scrape_article_selenium). Paid articles sometimes take longer to render after login.
