Substack vs Beehiiv

Substack leads on intent; Beehiiv owns feature and budget questions. Substack's edge comes down to one signal: when a model is asked to name a single tool, it picks Substack 39% of the time versus Beehiiv's 17%, and Claude in particular pushes that gap with a 12-point model score advantage. Beehiiv counters on feature-led and budget-framing questions, where buyers comparing specifics find it more frequently recommended, and Gemini actually scores Beehiiv marginally ahead of Substack. The overall citation rate is identical at 68%, so the real separation is positioning, not reach: Substack is the instinctive first answer, Beehiiv is the rational second look.
