Ghost vs Substack

Ghost leads overall; Substack owns the first-pick and startup questions. Ghost holds a higher Visibility Score and gets named in 76% of answers versus Substack's 68%, driven almost entirely by Gemini, where Ghost scores 74 against Substack's 54.6. Substack punches back on the metrics that matter to buyers making a final call: it is chosen first 44% of the time compared to Ghost's 26%, and it wins both the startup-and-small-team and the 'if you could pick one' question themes. ChatGPT and Claude both prefer Substack, which means Ghost's overall lead rests heavily on Gemini's strong preference rather than a consensus across models.
