About this app

A simple tool for building stories.

Multi-platform

This app is where ever you are. Your phone, tablet, desktop, laptop, this program can be installed and run, not simply a website-in-a-box, but instead using native client side technologies to provide the best experience possible.

Multi-Screen

Whether you are on a phone, tablet, or desktop, Hammer will make the best use of your screen space. Also supporting both light and dark modes.

Offline first

I was frustrated with most of the story writing software I was finding as they were using web technologies (aka: Web Page in a box) which always seems to run into problems while being used offline for long periods of time. Hammer is designed from the ground up to be entirely local, no internet connection required, ever.

Transparent Data

Your data is yours. It's not stored in the cloud, or some opaque database. It is stored in simple, human readable files, just using files and folders to define the project structure. You can open your OSes file browser and take a look for your self. If this program went away today you would be able to easily interact with your data.

Intelligent Syncing between devices

Your data can be synchronized between devices allowing you to work on your story from anywhere, and have no fear of a change on one device, overwriting a change on another device.

Optional and Self hosted Syncing

Syncing is entirely optional, you can install the client and use it on one device, or you can install the server and sync your data between devices. You could even use some other service to sync your data, like Dropbox, Google Drive or syncthing. (however these will only work for syncing between desktop computers. Mobile clients will have to use the built in syncing protocol.)

It's all up to you. Instructions can be found here: https://github.com/Wavesonics/hammer-editor/blob/develop/docs/HOW-TO-RUN-A-SERVER.md

If you don't know how, or just don't want to setup your own server, we're also running an official syncing server.

Official Server: hammer.ink

This is also the best way to support the project! Subscribe to our Patreon in order to get instant access to this official Sync server.

This official server endeavors to be a reliable, and secure way to sync your projects. We perform regular backups, and of course encrypt all of our data both in transit, and at rest in our database. Let us manage the server, and you worry about writing!

What's new

v3.8.0Aug 5, 2026
  • Set the language a project is written in, and have spell check follow it
  • Self-service account deletion from the web dashboard, with an admin restore window
  • Import and export documents as HTML, alongside Markdown
  • "What's New" release notes shown in-app with no network request, and reopenable from About
  • Import preview warns when a scene comes in unusually large, so a failed chapter split doesn't quietly collapse a manuscript into one scene
  • Text editor: faster typing and relayout, word-wise undo with a much deeper history, and rich copy and paste that preserves formatting between apps
  • Text editor: platform-correct key bindings on macOS, and AltGr chords type their character instead of firing shortcuts
  • Large Markdown imports are dramatically faster: 1600 scenes went from 37 seconds to about 3
  • Search matches the rendered prose, resolving Markdown escapes and formatting
  • Tag search matches accented and non-latin characters, and searches entry names as well as bodies
  • Scene drag and drop stays accurate while the list autoscrolls
  • Chapter detection on Markdown import understands Setext-style and bold titles
  • Visible scrollbars on scrolling screens, and scroll-away footers float over their lists
  • Translations updated for German, Spanish, French, Italian, Portuguese (Brazil), and Ukrainian
  • Server: the setup page can create the initial admin account
  • Server: a self-hosted server not serving HTTPS now reports a clear error instead of "Network error"
  • Server: smaller Docker image
  • Web: error responses show a toast instead of failing silently
  • Client: importing a very large story no longer freezes the app
  • Client: scene drag could grab the wrong row
  • Client: literal ** and _ left around emphasis imported from RTF
  • Client: sync server URLs are normalized consistently when saved
  • Client: a number of text editor crashes around undo, paste, and joined paragraphs
  • Web: htmx requests denied access landed on a blank page instead of being redirected
  • Web: broken download link on the home page
