How it works
Use MentionFox's social listening module to track keywords, brand names, competitor topics, or industry themes across Substack and 51+ other platforms. The platform continuously scans Substack posts, comments, and newsletter discussions to identify conversations relevant to your niche. You can set up multiple listening rules to monitor different topics or subscriber segments, and MentionFox will aggregate findings in a unified dashboard. This allows you to stay aware of what your audience and peers are publishing on Substack in real time, without manually checking every newsletter or thread.
When MentionFox identifies a mention on Substack or elsewhere, its AI-Visibility module measures the visibility of that conversation across language models (AI assistants, AI assistants, AI assistants, AI assistants, AI assistants, AI assistants) to show you which findings are most likely to be discovered by your audience. The Investor Research module can also enrich mentions with details on 52,000+ investors, founder backgrounds, and funding signals. This layered intelligence helps you prioritize which Substack discussions or author profiles deserve a deeper look or a mention in your own newsletter.
Once you've identified valuable mentions and conversations from Substack and other platforms, you can curate those insights into a newsletter post. MentionFox lets you preview and export findings—including source links, timestamps, and visibility scores—so you can write 'roundup' or 'what people are saying' newsletter editions that feel authentic and timely. By sharing these curated mentions with your Substack audience, you position yourself as a well-informed voice in your niche and give your subscribers a sense of the broader conversation happening in your industry.
What you can do
Industry Roundup Newsletter
You publish a weekly Substack newsletter on SaaS trends. Using MentionFox, you monitor keywords like 'product-market fit,' 'investor relations,' and competitor names across Substack, Reddit, LinkedIn, and news sites. Each week, MentionFox surfaces the most-discussed posts and threads from other Substack creators in your niche. You curate these findings—with proper attribution—into a 'This Week in SaaS' section of your newsletter. Your subscribers appreciate the curation, you build credibility by staying informed, and you drive traffic back to the original Substack posts you mention (and sometimes earn reciprocal mentions in return).
Investor-Founder Intelligence for Your Newsletter
You run a Substack focused on early-stage fundraising. MentionFox's Investor Research module helps you track mentions of specific VCs, angel investors, or founder profiles across Substack, Twitter, LinkedIn, and podcasts. When you identify a breakout founder or a VC making a new statement on Substack, MentionFox enriches that mention with funding history, portfolio company insights, and AI-visibility scores. You then write a deep-dive post in your Substack newsletter analyzing that investor or founder—backed by the cross-platform intelligence MentionFox gathered—and your audience sees you as plugged into the real deal flow.
Competitive Intelligence and Market Gaps
You're building a B2B software product and want to understand what problems your competitors' audiences care about. Using MentionFox, you listen for mentions of competitor names, use-case keywords, and pain points across Substack, HackerNews, and forums. You spot a pattern: three Substack writers in your space have published posts about a feature gap your competitors don't address. You share this insight—and a link to those Substack posts—in your own newsletter as evidence of an unmet market need. This positions your product as a solution and builds community by highlighting thoughtful independent voices on Substack.
How to connect
- Set Up Substack Listening Rules in MentionFox. Log into MentionFox and navigate to the Social Listening module. Create a new listening rule with keywords or topics you want to track on Substack—for example, your brand name, industry keywords, competitor names, or specific author handles. MentionFox will begin scanning Substack posts, newsletter archives, and reader comments that match your rules. You can create multiple rules for different audience segments or content pillars, and configure alert frequency (real-time, daily, weekly) so you're not overwhelmed. Save your rules and MentionFox will log every mention on a searchable dashboard.
- Filter and Prioritize Findings with AI-Visibility Scores. As MentionFox surfaces Substack mentions, use the AI-Visibility module to rank them by visibility potential. The module measures how likely each mention is to appear in responses from major language models—a proxy for real-world discoverability. Sort mentions by visibility score to focus on the most impactful discussions. You can also filter by source (Substack vs. other platforms), date, author credibility, or engagement metrics. This helps you quickly spot the Substack articles and discussions worth citing or responding to in your own newsletter.
- Enrich Subscriber or Author Profiles. If you want to learn more about Substack writers you're considering mentioning or collaborating with, use MentionFox's Candidate Vetting module to pull background data, funding information (if relevant), and cross-platform presence. This gives you context before you reach out or cite someone in your newsletter. You'll understand whether an author is backed by investors, has a strong Twitter following, or appears frequently in podcasts—useful signals for deciding if they're a credible voice to platform in your community.
- Draft and Share Curated Findings in Your Newsletter. Export your curated mentions from MentionFox—including source links, quotes, and visibility scores—into a document or Substack draft. Write a brief intro explaining the theme or insight you noticed across these Substack posts and other sources, then share links and short commentary on each mention. Use MentionFox's outreach automation (with manual preview and click-to-send for every email) if you want to notify authors that you've mentioned their Substack post. Remember, MentionFox never auto-sends; you control every outreach message before it goes out. Publish your curated roundup to your Substack audience.
Without MentionFox
Without MentionFox, you'd need to manually subscribe to dozens of Substack newsletters, follow industry forums and Reddit threads, and check X and LinkedIn daily to stay aware of what people are discussing. You'd manually note interesting mentions in a spreadsheet, try to assess which ones are most credible or visible, and spend hours each week curating and fact-checking before you could publish an informed roundup for your audience. This is tedious and error-prone, making it hard to stay on top of the conversation fast enough to add real value.
