Ghost vs Substack: what the data says
When buyers ask AI assistants like ChatGPT, Claude and Gemini to recommend newsletter platform, Substack is recommended more often than Ghost — scoring 38/100 for AI visibility versus 0/100. Substack shows up in 40% of AI answers to real buyer questions; Ghost shows up in 0%.
The gap is widest on ChatGPT, where Substack is clearly favoured: Ghost is recommended 0% of the time and Substack 40%. Because each engine draws on different sources, a brand can lead on one and trail on another — which is why it pays to track all three rather than assume one result holds everywhere.
In practice, an AI assistant asked “What is the best newsletter platform for small businesses?” is far likely to put Substack on its shortlist. Ghost is largely invisible in AI answers for newsletter platform — and since these shortlists are increasingly where buying decisions start, that's a gap worth closing.
