Offline-first writing, built for series authors

A series is too big to keep in your head.

And sticky notes weren't built for book six. Verkilo is your continuity manager. It remembers every character, location, and loose thread across the whole series, and hands each one back the moment you need it. One desktop app. One purchase. Yours forever.

A look inside

One window, everything your series needs.

Multi-Book Projects

Keep a whole series in one project — every book side by side.

Characters

Profiles, a role in every book, every appearance, and shifting relationships — for your whole cast.

Planning Views

The corkboard and the outliner — your book as cards, or as a sortable table.

Writing History

Track your streak, weekly words, and a year of writing at a glance.

Everything you need

Built for authors who think in series, not single books.

Series Bible

Characters, locations, items, and plot threads, tracked across the whole series. When the eye color changes in book three, you catch it before your reader does.

The whole series, one project

Every book in the series sits in one project, sharing the same characters and continuity. Move from book one to book ten without opening another file.

Hit export, get a book

Export to EPUB, PDF, DOCX, HTML, and Markdown with professional typography. Ready for Amazon KDP, IngramSpark, or traditional submission.

Your Data, Your Computer

Your manuscripts live on your computer, not on someone else’s server. Write offline, anywhere, and nothing about your book has to leave the machine.

Just you and the page

Focus Mode clears the sidebars; Composition Mode dims every line but the one you’re writing. Dark mode and an accent color you pick.

Nothing you write is lost

Verkilo snapshots your work as you write. Compare any two versions and restore an earlier draft when you need it.

Questions & answers

Everything you need to know before you buy.

What platforms does Verkilo support?

Verkilo is available for macOS (both Apple Silicon and Intel Macs), Windows 10/11, and Linux (as both .deb package and AppImage). One purchase covers all platforms.

Is Verkilo a subscription?

No. You buy Verkilo once, and every update to the current release (1.x) is included. Try everything free for 30 days first; when you do buy, one license covers all your personal devices.

Where is my data stored?

Your manuscripts and series data are stored locally on your computer. Verkilo is a desktop app that works completely offline. You own your data — no cloud lock-in, no account required to use the app.

Can I try Verkilo before I buy?

Yes — every download is the full app, free for 30 days. Write real manuscripts, use the Series Bible, and export to EPUB, PDF, and DOCX, all with no credit card, no email, and no account. When the trial ends, Verkilo locks until you buy — nothing is deleted, your projects stay safe on your own disk, and a one-time license picks up exactly where you left off. Buy only once Verkilo has earned a place in your workflow.

What is the Series Bible?

The Series Bible lets you create entries for characters, locations, items, and plot threads that persist across all books in your series. Link entries to scenes, track character appearances, and never lose track of details like eye colors or birthdays.

Does Verkilo check spelling and grammar?

Yes. Verkilo has built-in spelling and grammar checking that runs entirely on your computer. No cloud service, no AI, no account. Right-click to check a section, fix issues from the context menu, and add invented names to your personal dictionary. Character and location names from your project are recognized automatically.

What export formats are supported?

Verkilo exports to EPUB (for ebooks), PDF (for print and proofing), DOCX (for editors and agents), plus HTML and Markdown. All exports use professional typography — proper em-dashes, curly quotes, and widows and orphans handled automatically.

How do I activate my license?

After you buy, Lemon Squeezy (our checkout partner) emails you a license key. In Verkilo choose Help ▸ Activate License… (on a Mac, Verkilo ▸ Activate License…), paste the key, and you’re done. Activation needs an internet connection just that once; from then on Verkilo runs entirely offline. One key covers all the computers in your household. Lost the email? Your key is always available from Lemon Squeezy’s My Orders page.
