Overview

Scrape Substack by search query or direct URL to gather data on publications, people, posts, and notes. Ideal for identifying influential writers, analyzing content trends, or tracking competitor newsletters.

Substack is a major platform for independent writers, journalists, and subject-matter experts to build direct relationships with their audience. This tool allows you to extract public data from across the platform, giving you a structured view of its ecosystem for market research, lead generation, and content strategy. You can provide either broad search queries (like "fintech" or "generative ai") or a list of specific URLs for publications, writers, or posts. The tool will then collect the corresponding data, which you can filter to include only publications, people, posts, or the short-form 'Notes' feature. ### For Market & Competitor Research Analyze publications in your niche. For each one, you can retrieve its title, description, and whether it has a paid subscription. This helps you understand the competitive landscape, identify market gaps, and benchmark your own newsletter's positioning. ### For Influencer & Partnership Marketing Identify key writers and thought leaders. The scraper collects author bios, handles, and follower counts. This data is critical for finding potential collaborators, podcast guests, or influencers to sponsor. ### For Content Strategy Understand what resonates with audiences by scraping posts and notes. You can see post details, attached media, and engagement metrics like reactions and comments. This reveals trending topics and popular content formats, informing your own editorial calendar.
