Unmatched built-in discovery (Notes, recommendations, app) means writers grow from zero without an audience, zero upfront cost, and the strongest brand for paid subscriptions among readers
Gemini The lowest friction setup for starting a paid publication combined with a powerful built-in discovery network (Notes and recommendations) that drives high organic growth.
Grok Easiest for writers to start publishing and build community with built-in discovery, seamless paid subscriptions, and social-like features that help new creators gain visibility fast
GPT Easiest path for writers to launch, charge readers, and gain discovery through its recommendation network, app, Notes, podcasts, video, and built-in community
Where Substack falls short, per the models
- GPT Replace the 10% paid-subscription revenue cut with predictable flat pricing
- Claude Replace the flat 10% cut of paid revenue with a capped or tiered fee — successful writers outgrow the economics fast and churn to owned-stack alternatives.
- Gemini Eliminate or reduce the flat 10% revenue share fee for high-earning creators in favor of flat-rate tier pricing.
- Grok Add robust automations, segmentation, and better custom branding/SEO ownership to compete on professional growth

Zero cost until you monetize, built-in recommendations network that genuinely drives subscriber discovery, and frictionless paid subscriptions — the fastest path from nothing to a paying technical audience, which keeps it ranked despite weak dev ergonomics
Grok Extremely easy onboarding, built-in discovery, payments, and audience tools; handles technical writing adequately with good formatting; massive network effects for visibility in tech circles.
GPT Fastest route from zero to a functioning free-or-paid publication, with frictionless publishing, payments, comments, recommendations, Notes, podcasts, and meaningful built-in discovery
Gemini The lowest friction, zero-cost setup with a built-in recommendation engine for discovery, making it ideal for writers who want to publish without configuring any tech stack.
Where Substack falls short, per the models
- GPT The 10% paid-subscription fee and limited control over design, automation, and site architecture make it a poor long-term fit for technically demanding or high-revenue publishers
- Claude Poor fit for technical content itself — clumsy code formatting, no markdown editor or API, 10% revenue cut, and your growth rides on a platform whose network and policies you don't control
- Gemini Offers no developer API, custom CSS styling, or Markdown-first editing, giving writers no programmatic control over their platform.
- Grok Platform takes 10% revenue cut and owns the relationship/data to some degree; less flexible for custom dev integrations or full export control (not for those prioritizing independence or avoiding platform dependency).
