3. Global Library

Everything you need to
engineer your story.
Writing a book is not just typing; it is architecture. Blue Period provides a structural environment for novels, technical books, and essays.
Structure First.
Don't get lost in the sea of text. Organize your ideas into a hierarchical tree. Drag, drop, and restructure your narrative as easily as refactoring code.
- Nested Hierarchy (Part > Arc > Chapter > Story > Section)
- Drag & Drop Reordering
Understanding Recursion
To understand recursion, one must first understand recursion. Below is a classic example using the Fibonacci sequence.
function fibonacci(n: number): number {
if (n <= 1) return n;
return fibonacci(n - 1) + fibonacci(n - 2);
}
Notice how the function calls itself. This is the essence of...
Not just for Fiction.
Blue Period is a "Web Book" platform. Whether it's a technical book with code blocks, a photo essay, or a philosophy treatise, we support the format your intellect requires.
- Markdown & Code Syntax Highlighting
- Image & Media Support
Your Intelligent Partner.
Stuck on a plot hole? Discuss it with the AI. Simulate conversations with your characters to deepen their personalities. It's not just auto-complete; it's a creative dialogue.
What drives the protagonist in this scene? Is it anger, or resignation?
It's resignation. He knows he can't win, but he has to try anyway.
I see. In that case, let's describe the rain not as a storm, but as a cold, indifferent curtain.
Quality is not accidental.
It is Engineered.
We believe that a great reading experience starts with a great filter. Every published work on Blue Period undergoes a rigorous AI-based review process before it reaches the public library.
-
Completeness Guarantee
No more abandoned cliffhangers. The system verifies that the narrative has a proper conclusion.
-
Safety & Ethics
Automatic filtering of prohibited content ensures a safe environment for all readers.
Not a Censor, but a Companion.
We are not the Thought Police. We do not judge your ideology, your themes, or your passion.
Our AI reviewer is modeled with a specific persona: "A supportive teacher who wants to give you a perfect score!"
As long as your story is complete and adheres to basic safety guidelines (no illegal acts or graphic violence), we welcome any world you wish to build.

Bring Your Own Key BYOK
Your creativity should not be capped by our subscription tiers. Connect your own API keys (OpenAI, Anthropic, Google) directly. You pay for what you use, directly to the provider. We are just the interface.
- • No hidden markups on token costs.
- • Freedom to switch AI models instantly.
Bring Your Own Data BYOD
Your drafts live on your device, not our servers. We provide the studio; users hold the keys to the vault. This means total privacy, but also total responsibility for your backups.
- • Local-First Architecture.
- • Zero data mining on your drafts.
- • You own 100% of your IP.
Qualitative First
We distance ourselves from the noise of "likes" and ephemeral trends. Our mission is to help you craft something that lasts. We focus on the depth of the connection between one writer and one reader.
- • No gamification of creativity.
- • Designed for deep work.
- • Respect for the reader's time.
Let us carry the
weight of your data.
True ownership (BYOD) implies total responsibility for backups. But you don't have to bear that burden alone.
Upgrade to Blue Period Pro.
We provide automated, encrypted cloud backups, so you can focus
entirely on weaving your story, knowing your legacy is secure.
Cloud backups sound convenient—but can you truly trust them with
your most precious work?
We built our system on a principle: even we can't read your
data.
Local-level privacy
in the cloud.
The Pro plan's cloud sync is built on a simple promise: your Sync Key is the only key in the universe that can unlock your work. We provide the vault, but we can't open it.
What We See: Gibberish
Our database only stores a scrambled, unreadable block of data. It's like a letter written in an alien language without a dictionary.
What You See: Your Story
Your device uses the Sync Key to decrypt the data back into your beautiful, structured book.
