Substack vs. Laterpress for Going Direct to Readers

Whether you’re writing serialized fiction or traditional books, going direct to readers is one of the smartest moves an indie author can make. Two platforms that enable this — Substack and Laterpress — take fundamentally different approaches.

Substack is a newsletter platform where some authors publish fiction. Laterpress is an AI storytelling platform built specifically for fiction writers, from brainstorming to publishing to monetization. This article breaks down how each works, where each shines, and which is a better fit depending on how you write and sell.

Substack

The subscription network for independent writers and creators

Substack is a San Francisco-based company founded in 2017 by Chris Best, Jairaj Sethi, and Hamish McKenzie. Originally aimed at journalists and essayists, it has grown into a broad platform for writers of all kinds — from political commentators to fiction authors. As of early 2025, Substack has over 5 million paid subscriptions and 50 million active subscriptions across the platform.

At its core, Substack is an email newsletter platform. Authors write posts, and those posts land directly in subscribers’ inboxes. The format works well for essays, commentary, and episodic content — and some fiction authors have adapted it for serialized storytelling.

Why it might be right for you

Connect Directly with Readers

Substack newsletters create a direct line to your readers’ inboxes. This immediate relationship builds loyalty and keeps your work top of mind, as long as you’re consistent and readers find value in what you send.

Large Built-In Network

With over 5 million paid subscriptions, Substack has significant brand recognition. The platform’s recommendation engine and Substack Notes — a social feed where writers share quick updates, snippets, and engage with other writers’ audiences — give fiction authors more discoverability tools than the platform had even a year or two ago.

Ease of Use

Substack’s editor is genuinely good. You can be publishing within minutes, and the platform handles payment processing, subscriber management, and email delivery. For authors who want minimal technical overhead, it’s hard to beat.

Serialized Fiction-Friendly

Stories released in installments can work on Substack. Authors publish regular chapters as posts, building anticipation and encouraging subscriptions for access to new content. The episodic delivery model maps naturally to serial fiction.

No Cost to Start

Substack is free to use. Authors can build an audience without any upfront costs. However, once you start charging for subscriptions, Substack takes a 10% cut of your revenue.

Monetization

Substack’s monetization centers on paid subscriptions. Authors set a monthly or annual price (typically $5–$20/month), and subscribers get access to paywalled content. Authors can also offer free posts alongside paid ones to attract new readers.

In dollar terms: on a $10/month subscription, Substack takes $1, Stripe takes roughly $0.59 (including a recurring billing fee added in 2024), and you keep about $8.41.

Why it might not be right for you

It’s a Newsletter, Not a Book

This is the fundamental tension. Substack delivers chapters as individual emails or blog posts. There’s no table of contents, no progress saving, no chapter navigation, no book-like reading experience. Readers scroll through posts in reverse chronological order. If someone discovers your serial 20 chapters in, they’re scrolling backwards through an archive — not opening a book.

For readers, the experience feels more like following a blog than reading a novel.

Lost in a Crowd

Substack’s audience is massive, but so is its contributor base. Over 40,000 creators have paying subscribers. Discovery is improving with Substack Notes and the recommendation engine, but fiction remains a niche on a platform dominated by journalism, politics, and nonfiction commentary. Authors still need to drive most of their own traffic through social media and external marketing.

Email Delivery Limitations

While Substack now allows you to edit posts on the web after publishing, emails that have already been sent to subscribers can’t be changed. If you catch a plot hole or a critical typo after hitting publish, readers who opened the email version have the old text. This is manageable for essays but more painful for fiction where continuity matters.

Platform Fees Add Up

Substack takes 10% of subscription revenue, plus Stripe’s processing fees (approximately 3.6% including the recurring billing surcharge added in July 2024). Combined, authors keep roughly 86–87 cents of every dollar earned. On top of that, Substack charges a one-time $50 fee to use a custom domain.

For a serialized novel released over 10 months at $5/month, a single reader pays $50 — and the author keeps about $43 after all fees.

Subscription Fatigue

Readers are juggling more subscriptions than ever — streaming, news, software, and now individual writers. Asking a reader to commit to a monthly fee for a single author’s fiction is a harder sell than a one-time book purchase. If readers don’t know what they’re committing to, they may not commit at all.

Inbox Overwhelm

Readers receive dozens of emails daily. A chapter that arrives alongside work emails, promotions, and other newsletters can easily be missed or deleted unread. If a reader misses a few chapters, they may lose the thread of the story entirely and cancel.

Laterpress

The AI storytelling platform for fiction writers.

Laterpress is a purpose-built platform for fiction writers that covers the entire creative workflow — from brainstorming and worldbuilding to drafting, editing, publishing, and monetizing. Authors publish books and serials directly from their own custom domain, with a web-native reading experience designed for long-form fiction.

Where Substack is a newsletter platform that some authors use for fiction, Laterpress is a fiction platform from the ground up.

AI Storytelling Tools

This is Laterpress’s core differentiator — and something no newsletter platform offers. Laterpress integrates AI tools directly into the writing workflow:

• Wiki system: Idea cards, character cards with traits and visibility toggles, lore entries across 10 worldbuilding categories, and scene cards — all linked to your manuscript
• AI generation: Generate characters, lore, outlines, and drafts from seed ideas, or extract wiki cards from existing chapter text
• Custom story tools: Build personalized AI prompts with up to 3-step prompt chains, using different models per step from OpenAI and Anthropic
• AI editing suite: Highlight text for thesaurus suggestions, tense scanning, expansion/condensation, rephrasing, and plot hole detection
• Author Assistant: Freeform AI chat with full manuscript context — your chapters, characters, lore, and outlines

These tools are optional. You can use Laterpress purely for publishing and never touch the AI features. But for authors who want AI assistance without leaving their writing environment, it’s a significant advantage.

Built for Book Reading

Laterpress is designed to feel like reading a book, not scrolling a blog. The web-native reader includes:

• Chapter-based navigation with an auto-generated table of contents
• Progress saving — readers pick up exactly where they left off
• Swipe navigation between pages and chapters
• Customizable fonts, themes, and dark mode
• No ads, no distractions

See the Reader Experience Overview for a visual walkthrough. Readers access books from any device without downloading an app — just open a link and start reading.

0% Commission on Direct Sales

Laterpress takes 0% of your direct sales revenue. You keep everything minus Stripe’s standard processing fee (2.9% + $0.30 per transaction). Compare that to Substack’s 10% platform fee plus elevated Stripe fees.

On a $10 book sale, you keep about $9.41 on Laterpress versus $8.41 on a $10 Substack subscription.

Flexible Monetization

Authors have full control over pricing. You can:

• Sell books as a one-time purchase
• Offer chapter bundles (pay-as-you-go)
• Set up monthly or annual subscriptions
• Mix free and paid content across multiple books
• Offer EPUB downloads for purchased books

Set up a Stripe account to start receiving payments, and learn more about monetization options.

Free Custom Domains

Publish books from your own branded URL — like books.yourname.com — at no extra cost. Your branding stays front and center, and readers don’t even have to know Laterpress exists. Unlike Substack’s $50 custom domain fee, this is included for every author.

Custom domains also mean no platform lock-in. Your URLs are yours.

Publish and Update Anytime

No approval process. All genres welcome. Update any chapter at any time — readers always see the latest version. Schedule chapter releases for serialized fiction, so your serial runs on autopilot.

Reporting

Real-time reporting on readers and payments. See who’s reading, how far they’ve gotten, and where they drop off — data that helps you understand what’s working in your story.

Why it might not be right for you

You Are Responsible for Your Traffic

Laterpress is built for direct sales. Readers who find your book on Laterpress are readers you brought there — through your newsletter, social media, or other marketing. That’s a big part of why Laterpress takes 0% of direct sales: you did the work, you keep the money. But if you’re hoping for a built-in browsing audience like Substack’s network, Laterpress isn’t that.

Direct Sales Mean Tax Responsibility

Because sales revenue goes directly to you via Stripe, you’re responsible for any applicable taxes. Check your state’s economic nexus laws — for most states, the threshold is at least 200 sales in a 12-month period. When in doubt, talk to an accountant.

Community Discovery is Growing

Laterpress’s community features — reader recommendations, ratings and reviews, affiliate links — are functional but still maturing. Authors looking for a large built-in marketplace will find Substack’s network larger. That said, Laterpress is designed so that community features grow the platform’s revenue alongside the author’s, aligning incentives.

Use Both Together

Here’s what many authors miss: Substack and Laterpress aren’t mutually exclusive. A smart strategy is to use both:

• Substack as your free newsletter — build an audience, share writing updates, tease new chapters, engage with readers through Notes and comments
• Laterpress as your bookstore — where the actual books and serials live, with a proper reading experience, chapter navigation, and direct sales

This way you get Substack’s audience-building tools without paying 10% on your fiction revenue. Your newsletter drives readers to your Laterpress storefront, where they buy at 0% commission. You own the reading experience, the custom domain, and the reader relationship.

Which Should You Choose?

Choose Substack if:

• You’re primarily a nonfiction writer or essayist
• You want to build an email audience before you have a book to sell
• Newsletter-style delivery fits your content (commentary, updates, short essays)
• You value Substack’s large built-in network and Notes social features

Choose Laterpress if:

• You’re writing fiction — serialized or complete books
• You want AI tools integrated into your writing workflow
• A book-like reading experience matters to you and your readers
• You want to keep 100% of your sales revenue (minus Stripe fees)
• Custom domains and data portability are important to you
• You want flexible pricing: one-time purchase, bundles, or subscriptions

Choose both if:

• You want to use a free Substack newsletter to build audience, and Laterpress to sell the books

Both platforms require authors to do the work of building their audience. The question is: when a reader is ready to pay, would you rather they read your story in an email archive and give up 10%+ in fees — or in a purpose-built book reader where you keep everything?
