Free. Private. No AI. Catches your plot holes.
KoraKagaj is novel writing software with a story bible that checks your continuity for you. It runs in your browser, keeps your book on your device, and exports print-ready files for Amazon KDP.
No account. Nothing to install. Your book stays on your device.
Features
Everything a novel needs, from first draft to paperback
Story Check
Catches a dead character who speaks again, a misspelled name, an age that doesn't add up, eyes that change colour, and plot threads you never closed. Plain rules, no AI.
A story bible that stays in sync
Characters, places and plot threads, linked from your text with @mentions. See every chapter a character appears in.
Style checks
Repeated words, filler words, long sentences, adverbs and passive voice, plus chapter stats: dialogue versus narration and who speaks most.
Daily goals and streaks
Set a daily word goal and keep a streak going. Deleting words never costs you progress, so editing days still count.
Print-ready books
A PDF for Amazon KDP and IngramSpark with the right margins for your page count, mirrored pages, front matter, and a cover with the spine sized for you.
A calm place to write
Focus and typewriter modes, version history, comments in the margin, and EPUB and Word export when you need them.
Privacy
Your book never leaves your device
Stored in your browser
Your chapters, notes and images live in your browser's own storage on this device. There is no account and no server copy.
Keeps working offline
Install it like an app. Once you've opened a book, you can keep writing it without a connection.
Backups you control
Download a backup file any time, or point it at a folder (in Chrome and Edge) for automatic daily copies, including into a Dropbox or Google Drive folder.
The one network call: when you paste a link into Research, the link itself is fetched to show a title and image. Your writing is never sent. Read the privacy page.
Print templates
Paperbacks that look professionally typeset
Classic
Garamond, justified, centred chapter openers with a fleuron. The traditional novel.
Modern
Source Serif with large left-aligned chapter numbers and clean running heads.
Minimal
Crimson Pro, ragged right, no running heads. Quiet and spacious.

Questions
Good to know
- Is it really free?
- Yes. Every feature is free with no limits on books or words. The project is funded by optional print template packs, sold once, and by donations.
- Where is my book stored?
- In your browser's storage on your own device. Nothing you write is sent to a server. The one exception: if you paste a link in Research, that link (and only the link) is fetched to show a preview.
- What happens if I clear my browser data?
- Your books would be deleted, like any local file. Download a backup now and then, or turn on folder backup, and you can restore everything in a minute, on any computer.
- Does it use AI?
- No. It never writes for you and never sends your text to an AI. Story Check and the style checks are plain rules that run on your device.
- Can I publish on Amazon KDP with it?
- Yes. Export a print-ready PDF interior with fonts embedded and margins set for your page count, plus a matching cover PDF. Always check the proof in KDP's previewer before you publish.
- Does it work on a phone?
- It runs in a mobile browser, but it's built for writing on a laptop or desktop with a keyboard.
