Hey Sumo-lings! 👋

Casper here, co-founder of First Book ai.

We've shipped a lot since our last launch. Here are the three things you'll notice on day one.

✍️ The writing flow is completely new

You don't have to arrive with a plan anymore.

The AI helps you come up with ideas, suggests angles, and asks the right questions along the way. You just react.

It feels more like a conversation than a form. And the books coming out are much better.

🌍 Write in 12 languages

English, Spanish, French, German, Portuguese, Danish, Norwegian, Swedish, Dutch, Italian, Polish and Finnish.

Real writing in your language, not translation.

And new this round: you can change the language of a book you've already written. One click. Write it in English, publish it in Spanish the same day. 🤯

🎨 Design your own cover

Generate a cover, set the title, add your own text, tweak the layout.

The cover you make is the cover you upload to Amazon. No Canva. No designer. No extra cost.

💬 Plus 350+ authors to write with

The First Book Author's Club on Skool is now 350+ members. People sharing what worked, what sold, and what they're stuck on.

Included with every tier.

💛 What this means for you

Everything above is included in every tier, right now. No upgrade, no add-on, no waiting.

And you keep all the good stuff you already had: unlimited outlines, chapter-by-chapter control, your writing coach, and export to Google Docs, Word and PDF.

Grab the deal, pick your language, and start your book today.

Then drop a comment and tell us what you're writing. We read every single one. 🙌

Hey Sumo-lings! 👋

We've got two major updates to share — both landing in the same week, and both shaped by what you've been asking for.

🌍 Write in your own language

Until now, First Book AI only generated books in English. That was a real ceiling for a huge part of our community — authors who think, speak, and sell in their native language were stuck translating their way through the tool.

Not anymore.

First Book AI now generates in your preferred local language. ✍️

This has been one of our most requested features for a long time, and it's finally live. Whether you're writing in Spanish, German, Portuguese, French, or beyond — you can now create your book in the language your readers actually read in.

🎨 The Book Generator just got a major upgrade

We didn't stop at languages. We also shipped a big upgrade to the book generator itself.

Before, you got a cover. Now, you can actually customize the cover — and use it immediately to:

📚 Self-publish your book

📣 Promote it across your channels

🚀 Launch faster, without a separate design tool

No more "good enough" placeholder covers. The thing you generate is the thing you ship.

💛 What this means for AppSumo buyers

If you're grabbing the deal right now, you get both of these — straight away. No upgrade, no add-on, no waiting.

Two major releases in one week. And there's more on the roadmap that we can't wait to put in your hands.

Open your workspace, pick your language, design your cover, and tell us what you're writing first. We read every comment.

We're just getting started. 🙌

Hey Sumo-lings!

It's Casper here — and I have a small but meaningful update for our Tier 4 members.

We've just increased the monthly full books limit on License Tier 4 from 15 to 20 books per month.

That's 5 more manuscripts every month — at no extra cost.

Why the change? Simple: we kept hearing from our most active authors that they were hitting the ceiling. Whether you're running client projects, building a content library, or just on a writing streak, we didn't want the plan to slow you down.

This update is live now. No action needed on your end.

As always, thank you for being part of the First Book ai community. Your feedback genuinely shapes what we build — and updates like this are proof of that.

Now go write something great. 📖

Cheers,

Casper & the First Book ai Team

Hey Sumo-lings! 👋

I’m Casper, co-founder of First Book ai—and we’re back on AppSumo!

Since our last launch, a lot has happened.

First Book ai has now helped 2,400+ authors across 60+ countries generate more than 10,000 books. Seeing that many ideas turn into real manuscripts has been unreal. And as always, we listened carefully to the feedback.

That’s why we’re launching Version 3.0.

This is not a small update. We rebuilt the platform from the ground up.

What’s new in Version 3.0?

✅ Completely redesigned app with a clear chapter-by-chapter writing flow

✅ Stronger, more consistent AI output across the entire book

✅ Improved onboarding so your manuscript truly reflects your voice and expertise

✅ Smoother editing and regeneration experience inside each chapter

✅ A brand-new Author’s Club community to help you go from finished manuscript to published book

The biggest change is the structure.

You now move through your book step by step. Chapter 1. Then Chapter 2. Then Chapter 3. Each chapter builds naturally on the previous one, creating a cohesive, professional manuscript from start to finish.

If you missed us before, here’s why we built this in the first place:

After writing my first book, which took more than two years, I knew there had to be a better way. Lucas and I created First Book ai so busy professionals could finally turn their knowledge into a real book without spending years doing it.

How does it work? 🤖

You answer a few guided questions about your idea, expertise, and stories. Our AI then crafts a structured nonfiction manuscript based on your input. Think of it as having a focused co-author helping you go from idea to full book—without the overwhelm.

And now, with the Author’s Club, we help you with what comes next:

📖 Finalizing your book

📖 Covers and formatting

📖 Self-publishing step by step

📖 Approaching publishers

📖 Using your book to grow your brand or attract clients

To everyone who supported us before—thank you. And to those discovering First Book ai for the first time, welcome.

We can’t wait to help you write your book.

Cheers,

Casper & the First Book ai Team

Hey Sumo-lings! 👋

Yep, we’re back—launch #3!

It’s Casper here, co-founder of First Book ai, and I just want to say: wow. Over 1,000 new authors have joined us since we first launched on AppSumo.

The stories you’ve shared, the feedback you’ve given, and the books you’ve published… it’s been wild—in the best way. And we’ve used your input to make this version our biggest and most flexible yet.

Here’s what’s new for this round:

🚀 Tier 5: You asked for more firepower—so we added it. Now you can generate 20 full books + 20 blueprints every month.

🌍 Languages: Multilingual support is here.

⚙️ More control: Outline flexibility, better editing, and smarter structure options.

New here? Here’s what First Book ai does:

You answer a few guided questions.

Our AI ghostwriter turns that into a full, professional book draft.

No fluff. No wasted time. Just a clean manuscript in hours—not months.

Perfect for coaches, consultants, solopreneurs, and creators who want to grow their credibility, build a lead magnet, or finally get that book idea out of their head and into the world.

Real talk from fellow Sumo-lings:

🗣️ “The draft was returned about two hours later and was brilliant… three days later I was published on Amazon!” — LeadWorks

🗣️ “Some books were almost ready to publish after the first try. The interface is intuitive and easy to use.” — CyberSumo

🗣️ “It does exactly what it promises: blueprints or full books based on a handful of questions. A 160-page book in 24 hours is impressive.” — 2bdb880…

And this gem from another user:

🗣️ “It felt like having a writing coach + ghostwriter in one.”

We’re super proud of what’s new in this version—and incredibly grateful to the Sumo-lings who’ve helped shape it.

So if you’re ready to finally write that book (without locking yourself in a cabin in the woods), now’s the time.

Let’s make you an author.

Cheers,

Casper & the First Book ai Team
