Worldbuilding and manuscript, side by side.
No card needed

Bring the manuscript you already have. Upload a Word or Markdown file and Neku turns it into chapters, ready for you to keep writing.
Drop in a .docx or .md file, whatever you've already got. No copying and pasting chapter by chapter.
Neku detects your chapters automatically. Check the preview, hit import, and you're straight into your story.
It starts scattered. Characters, places, half-formed scenes you can't hold in your head. Lay them on the Storyboard until the shape appears. The mess becomes a map you can actually work from.
Use one of the storyboard cards to map your ideas — each card is its own full editor.
Connect cards that belong together — a character to a place, an idea to an event. Those connections then surface as annotations right inside your text.
Mention a card title in your prose and it lights up as an annotation. Your story map, right inside the editor.
You planned in one place, now you're writing in another, flipping back and forth while your notes go stale. Not here. Your map sits beside the page, so mention a character or place by name and it lights up in your prose.
Everything you need to style your prose, from headers to blockquotes, without the bloat.
Fully mobile-responsive. Whether you're on a train or a couch, the page is ready when you are.
Forget the 'save' button. Your progress is synced instantly as you type.
Dim the noise and drop into a distraction-free view, with a timer and ambient sound to keep you in the zone.
View your Storyboard connections, then hide them to get back into the zone.
Simplicity is the cure for writer's block. Start writing immediately, with zero setup.

Got questions? hi@neku.io
Yes, and the Free plan is free forever, not a trial that expires. You can write, organize, and export in Neku without ever paying. Paid Pro adds the Storyboard and Annotations, and every account gets a 30-day Pro trial to try them with no card needed.
No. Neku has no AI writing or generation, and your work is never fed to AI, used to train anything, or shared with third parties. Your story stays yours. The whole idea behind Neku is tools that help you write, not something that writes for you.
Yes. Upload a .docx or .md file and Neku automatically splits it into chapters, ready for you to keep writing. You don't have to start from a blank page.
Anytime, to DOCX, PDF, or Markdown. Your writing is never trapped in Neku. You can take a clean copy with you whenever you want, for backup or to work elsewhere, with no lock-in.
Pro unlocks the Storyboard, a visual canvas for mapping your characters, locations, events, and ideas, and Annotations, which surface those connections right inside your prose as you write. It's the link between planning your story and actually writing it.
Nothing is lost. You simply drop back to the Free plan with all of your writing fully intact, and you keep everything you've written. You can also export it all at any time, so downgrading never puts your work at risk.
No. When you share a story, anyone with the link can read it, with no sign-up and no paywall in their way. Only you need an account, and only for writing. Sharing your work with readers, beta readers, or friends stays completely frictionless.
One writer and developer building the tool he wished existed. Neku is a focused product made by someone who writes fiction and cares about getting the details right.
Yes. Neku works in your mobile browser, so you can pick up writing wherever you left off, whether you're at your desk or catching an idea on the go.
No AI. No noise. Just the tools that get out of your way and let you tell your story.
