Write the long novel without losing the thread.

Pendraic keeps your whole story in one place: the people, the world, your voice, every promise you made the reader. So the writing you do today still fits the book you started a year ago.

What Pendraic is

A real writing tool, not a chat window.

The editor is the center of everything. AI helps where you want it and stays out of the way when you don’t. The work stays yours.

Editor

An editor built for novels.

A clean writing surface that handles a hundred-thousand-word book without choking. Side panels for who’s in the scene, what beat you’re on, and any open threads you’re juggling.
Structure

Your story, organized eight ways.

Eight tabs covering everything a long novel needs: the premise, the people, the world, your voice, your beat plan, and your revisions. Chapter twelve still remembers what chapter one set up.
Your AI, your way

Pick your AI, or let us pick.

Bring your own account from Claude, ChatGPT, Gemini, Grok, or OpenRouter, or top up a Pendraic wallet and we’ll handle it. Switch any time.

The PENDRAIC Method

Eight pieces. One book.

A long novel has too many moving parts to keep in your head. Pendraic gives each one a home, and pulls them all together whenever you ask for help.

  1. Promise
    What kind of book this is, and what you're promising the reader. Genre, tone, the hook on the back cover.
  2. Engine
    What keeps the story moving. The big questions and the pressure that pushes your characters forward.
  3. Nexus
    The choices that turn the story. Where your characters pick a path and live with it.
  4. Dynamics
    Your scene-by-scene plan. Where each beat lands and how the tension rises and falls.
  5. Registry
    Everyone and everywhere. People, places, things, kept consistent so chapter twelve still matches chapter one.
  6. Anchors
    How your book sounds. We learn your voice and keep new pages on the same page as the rest.
  7. Iterations
    Every revision pass, saved. Draft, polish, humanize, compare versions side by side.
  8. Closure
    Setups and payoffs tracked from start to finish. Nothing you planted gets forgotten.

Pick your AI path

Bring your own, or let us handle it.

Two ways to power your writing. Connect your own account from Claude, ChatGPT, Gemini, Grok, or OpenRouter and pay them directly, or top up a Pendraic wallet and let us run the AI for you. Either way, you get the same writing tools.

Big jobs like a full read-through of your manuscript or a humanizing pass on a hundred pages run in the background. You can close the tab and come back when they’re done.

The promises we make

Your book is yours.

You own it

The book is yours.

Every word, every character, every note you write is yours. We don't claim rights to it, we don't license it, and we don't take a cut if you sell it.
Pendraic doesn't train

We don't feed your book to anything.

Pendraic doesn't train models on your work and we don't sell your content. When you ask for help, your text goes to the AI account you chose, under that provider's own terms.
Encrypted

Locked away when not in use.

Everything you save is encrypted on our servers. The connection between you and us is encrypted too.

How the AI helps

Quick answers, big jobs, and everything in between.

Quick help

Right in the editor.

Continue this scene. Describe this character. Tighten this paragraph. Answers come in under a minute, with your whole story already in context so suggestions actually fit.
Big jobs

Run while you're away.

Read my whole manuscript and find the inconsistencies. Humanize this chapter. Rework the ending across three chapters. These take a while, so you start them and come back.
Always tidy

Quietly keeping things in order.

When you edit something that affects the rest of the book, Pendraic notices and updates everything that points to it. You never have to clean up after yourself.

What you’ll use

The places you’ll spend your time.

Dashboard

Your writing day at a glance.

A single view of what you wrote yesterday, what's open across every project, and where to pick up. Quick links into the parts you use most.
Bookshelf

All your books in one place.

A grid or list of every book you're writing, grouped by series if you have one. Filter by status or genre. It remembers what you were last working on.
World Builder

The map, the cast, the rules.

Maps, family trees, calendars, languages, timelines, and encyclopedia entries that scale from a city block to a multiverse. Everything links back to the prose.
Editors

A clean place to write.

Full-screen prose, outline, and arcs editors with optional side panels for character lookups, voice consistency, the beat you're on, and any unresolved threads.

Frequently asked

Questions worth answering.

What does Pendraic actually do?
It’s a writing tool for long novels. You write your book in it, and it quietly keeps track of every part of your story so the writing you do today still fits the book you started a year ago. Eight tabs cover the things long novels need: your premise, the people, the world, your voice, your beat plan, and your revisions.
Do you train AI on my book?
No, Pendraic does not train AI on your writing, and we don’t sell your content to anyone. When you ask for AI help, your text goes only to the AI account you chose, under that provider’s own terms. Everything you save with us is locked away when not in use.
Which AI tools work with Pendraic?
Bring your own account from Claude, ChatGPT, Gemini, or OpenRouter. You can use a different one for different jobs if you want.
Is there a free version?
Yes. Free gives you the full editor, your Bookshelf, hands-on control of every part of your story, and exports to Word, Markdown, and plain text. It’s a real writing tool, not a stripped-down trial. AI writing help is on the paid plans.
What if I don't have a Claude or ChatGPT account?
You can buy AI credits from us and skip the setup. The price you pay covers what the AI actually costs, plus a small service fee that covers payment processing and our work running it. Credits never expire, you can refund any time, and there’s a $500 monthly cap so nothing ever runs away from you. Bringing your own account is cheaper and most writers do that. Credits are for the people who want it to just work.
Can I use Pendraic from Claude or ChatGPT directly?
Yes, on the Premium plan. You can connect Pendraic to Claude Desktop, ChatGPT, or any AI app that supports it, and read or update your book without leaving the AI you’re already using.
How do you keep my book consistent across hundreds of pages?
Pendraic remembers what you set up in chapter one and keeps it in mind every time you ask for help. Genre, tone, the people, the world, your voice. Chapter twelve still matches what you promised at the start.
Can I write with a co-author?
Not yet. Real-time co-writing is on the roadmap, and the editor we use already supports it. We’ll turn it on in a later release.
