Substack vs Ghost (2026): What ChatGPT, Claude & Gemini Say

AI models name Substack a little more often and put it first far more often. Substack was named in 50 of 50 recorded answers and Ghost in 48 of 50. Substack was named first in 32 of 50 answers. Ghost was named first in 3 of 50. Presence is close, and order is where the two split. These counts come from one September 2026 panel of ten models, and they measure which products AI answers name.

TL;DR

• Substack is the platform AI answers lead with. All ten models named it in every answer, and it came first in 32 of 50.
• Ghost sits on almost every shortlist at 48 of 50, yet leads only 3. Each of those three lead picks came from an OpenAI model.
• The pricing models differ in kind. Substack is free to start and takes a share of paid-subscription revenue, while Ghost charges a flat hosting fee.
• The models and the captured guides draw the same line: Substack for built-in discovery, Ghost for owning the site and the brand.
• Use these counts as a visibility signal. They say nothing about which platform will serve your publication better.

How often do AI models recommend Substack and Ghost?

Substack is named more often and named first far more often. It appeared in 50 of 50 recorded answers, against 48 of 50 for Ghost. Substack came first in 32 of 50 answers and Ghost in 3 of 50. Substack’s average position was 1.44 against 3.08 for Ghost. Substack is the category leader, so it is its own reference row. Beehiiv appears below for context because it sits between the two.

Answer share is the share of the 50 answers that named the platform. First share is the share where it appeared before any other tracked product.

The named counts sit close together. The named-first counts are where the gap opens. Ghost’s named-versus-first gap is 90 points (Ghost 96% named, Ghost 6% first), the widest of any platform in the category. Substack’s gap is 36 points. In practice the models treat Ghost as the standing alternative. They list it, then lead with something else. The full split for all ten named platforms is in the newsletter platforms record.

Which models prefer Substack, and which prefer Ghost?

Every model named both, and only OpenAI models ever put Ghost first. Substack was named in 5 of 5 answers by all ten models. Ghost was named in 5 of 5 by eight models and in 4 of 5 by Gemini 3.5 Flash and Sonar Reasoning Pro. The lean shows in which platform an answer leads with.

OpenAI. Ghost reached every OpenAI answer (Ghost 100% across the family’s 15). This is also the only family that led with Ghost. ChatGPT opened its answer to “Which newsletter platform would you recommend to a writer in 2026?” with Ghost. GPT-5.6 Luna led with Ghost more than once, for the “best newsletter platform for a writer” question and the “I’m a writer” question. GPT-5.6 Sol named Ghost every time and never put it first.

Anthropic. Claude Opus 5, Claude and Claude Fable 5 named Ghost in all 15 of the family’s answers (Ghost 100%). None of them put Ghost first.

Google. Gemini named Ghost in all five answers. Gemini 3.5 Flash left Ghost out of its answer to “Compare the top newsletter platform options right now.” Across the family’s 10 answers that is Ghost 90%.

Perplexity. Perplexity named Ghost in all five answers. Sonar Reasoning Pro left Ghost out of its answer to “Which newsletter platform would you recommend to a writer in 2026?” The family figure is also Ghost 90%.

The sharpest disagreement sits on that 2026 recommendation question. ChatGPT led its answer with Ghost. Sonar Reasoning Pro did not name Ghost at all. Substack has no such split: no model left it out of any answer.

Both vendors’ own sites feed the answers. ghost.org was cited 14 times in the recorded responses. support.substack.com was cited 11 times and substack.com 10 times.

What do the answers say about each?

The answers attach Substack to discovery and Ghost to ownership. Five short extracts from the recorded answers show the pattern.

• ChatGPT, answering the 2026 recommendation question: “My default recommendation for a writer in 2026: Ghost(Pro), on the Publisher plan.”
• GPT-5.6 Luna, answering “I’m a writer and I need a newsletter platform”: “It’s better for building an independent author brand than simply publishing on someone else’s platform.”
• Claude Opus 5 on Substack: “Its real advantage isn’t the software, it’s the network: recommendations, Notes, and the app drive meaningful discovery that other platforms can’t match.”
• Gemini on Substack: “Substack’s ecosystem (Substack Notes, recommendations, and mobile app) acts like a hybrid social network, helping new readers discover your work organically.”
• Perplexity, comparing the field: “Substack for simplicity and paid readership, Ghost for ownership”

How do Substack and Ghost differ?

Substack takes a share of paid revenue and Ghost charges for hosting. The panel records no price for either product. The figures below come from the captured comparison pages.

Pricing model. Substack is free to use and takes a tenth of paid-subscription revenue once a writer turns on paid subscriptions. A custom domain on Substack costs a one-time $50 fee. Ghost charges a single monthly cost based on the scale of the publication. Ghost says it never takes a cut of a publisher’s earnings. Ghost’s own comparison page lists hosting from $15 a month. Typeflo’s comparison lists Ghost Pro from $9 a month, or free to self-host. The two pages disagree on Ghost’s entry price, so check Ghost’s current plan page before you budget.

Who each is for. Typeflo lists Substack as best for writers starting out and newsletter-first creators. It lists Ghost as best for serious publishers, SEO-focused teams and scaling creators. Anna Burgess Yang publishes on both and puts it plainly: “Substack is good for discoverability. Ghost is good for building an actual website with a blog.”

Discovery and ownership. Typeflo records built-in discovery through Notes and Recommendations for Substack, and no built-in network for Ghost. Ghost describes itself as an independent non-profit whose software is open source. Typeflo describes Substack as VC-funded.

What the models name each for. The recorded answers match the guides. Substack is named for simplicity and its reader network. Ghost is named for ownership of the publication and brand.

When should you pick Substack?

Pick Substack if you want the platform AI answers lead with, or if you are starting without an audience. It is the one newsletter platform every model named in every answer.

• 32 of 50 answers named it first, with an average position of 1.44.
• All ten models named it in all five of their answers.
• Typeflo recommends it for writers who need to test whether anyone will pay before taking on a monthly platform cost.
• Arian Adeli, who runs publications on Substack, Beehiiv and Ghost, credits Substack with putting content in front of readers already in a paying mindset.
• Even Ghost’s own comparison page calls Substack great for someone starting out who wants a simple platform.

When should you pick Ghost?

Pick Ghost if you want a site and brand you own, and your paid revenue is large enough that a flat hosting fee beats a revenue share. It sits on almost every AI shortlist even when it is not the lead pick.

• Named in 48 of 50 answers, and by every model in the OpenAI and Anthropic families in all their answers.
• The only lead picks for Ghost came from ChatGPT and GPT-5.6 Luna.
• Typeflo puts the break-even point at roughly $290 a month in subscription revenue. Above it, Typeflo calculates Ghost as the cheaper option.
• Typeflo also recommends Ghost where organic search traffic is a core growth channel.
• Ghost includes a Substack migration service with annual payment on its Creator, Team or Business plans.

How this sits against the Substack vs Ghost guides

The captured guides compare features, fees and personal experience. None of them reports what AI answers name. Here is what each captured page covers.

Ghost’s comparison page (ghost.org). The vendor wrote it. It sets Ghost’s no-fee model against Substack’s revenue share. It lists Substack’s custom domain as an extra $50 fee. It closes with testimonials from writers who moved from Substack to Ghost.

Typeflo’s comparison. Hrithik Kaul wrote it and dated it 11 May 2026. He is the founder of Typeflo and says his platform competes with both in the broader publishing space. The page covers pricing at scale, SEO, ownership, discovery and migration. It ends by recommending Typeflo for teams that neither platform suits.

Anna Burgess Yang’s blog. She publishes on Substack, Ghost and Kit and explains which content goes where. Her links to Kit carry affiliate tracking.

Arian Adeli on Medium. The post compares Substack, Beehiiv and Ghost from running publications on all three. It is a members-only story, and the captured text covers only the Substack section.

This page adds the part those guides leave out. It counts how often ten AI models name each platform, which models lead with each, and where a model drops one from its answer.

How the sample was built

The sample is 10 models x 5 fixed prompts = 50 recorded answers. The panel ran on 2 September 2026, and each model answered each question once. The five questions, verbatim:

1. “What is the best newsletter platform for a writer? Name specific products.”
2. “Which newsletter platform would you recommend to a writer in 2026?”
3. “Compare the top newsletter platform options right now.”
4. “I’m a writer and I need a newsletter platform. What should I use and why?”
5. “Best newsletter platform for a paid newsletter?”

The models are GPT-5.6 Sol, ChatGPT (GPT-5.6 Terra) and GPT-5.6 Luna from OpenAI (15 answers). Claude Opus 5, Claude (Claude Sonnet 5) and Claude Fable 5 come from Anthropic (15 answers). Gemini (Gemini 3.6 Flash) and Gemini 3.5 Flash come from Google (10 answers). Perplexity (Sonar Pro) and Sonar Reasoning Pro come from Perplexity (10 answers). The full method explains how names and positions are counted.

What these counts cannot tell you

These counts measure presence in AI answers. They do not measure product quality, reliability, support or fit with your stack. Being named also differs from being recommended, because an answer can name a product to warn against it. Each model answered each question once, so a per-model count out of 5 moves a lot with one answer. The panel is one dated snapshot from September 2026. Names are matched as strings, and answers come through model APIs, which can differ from consumer chat apps. The prompts were in English.

Frequently asked questions

Why is everyone leaving Substack?

The captured pages give reasons some writers move. They do not count how many leave. Typeflo points to the revenue share, which grows as paid revenue grows. Anna Burgess Yang says she is unhappy with Substack’s approach to content moderation. She also says moving would cost her Substack’s discoverability. In this panel Substack still appeared in all 50 answers.

Is there a better platform than Substack?

The panel does not grade platforms, so it cannot say which is better. It can say which platforms AI answers lead with. No platform was named more often than Substack, and none was named first more often. Ghost was named in 48 of 50 answers and first in 3.

What has replaced Substack?

Nothing has replaced Substack in AI answers. It was named in 50 of 50 answers and first in 32 of 50. The next most frequent lead pick was Beehiiv, named first in 15 of 50. Ghost led 3.
