A tour of Chapbook
Every part of the write to publish loop
Chapbook is a local-first blog writing app. It turns a quick note into a real post, then commits it to a GitHub repo and Pages site that are yours. Here is what that looks like, feature by feature.
Chat composer
Write like you are texting a friend
Type a thought and send it. Each message becomes a block you can reorder, restyle or split. Twelve block types are a tap away, and the chat bar keeps the writing feeling light.
Every draft stays on your device until you decide to publish. Nothing leaves your machine without you asking.
Blocks and media
Twelve block types, plus a darkroom for your photos
Headings, quotes, code, galleries, tables, embeds and more. The built-in Darkroom resizes photos right in your browser and commits them straight to your repo.
Longer clips live in your own R2 bucket and stream into the post, so a video never bloats the page or the repo.
Interactive blocks
Make your posts interactive
Add quizzes, charts, calculators, decision tools and more. Start with a template, change it by hand, or ask AI. Here is one running exactly as it would on your published post.
This is live, not a video. It renders from the same engine that draws the widget on your published page.
A glyph for every idea
Search 5093 icons and place one in a heading or a card. Pick clean flat 2D, or an extruded 3D wireframe when a page wants a little depth.
AI partner
An editor on call, using your own keys
Bring a key from the provider you already pay for. Chapbook adds a writing Partner, a line-by-line Editor, a playful Goblin, and a Social pack that reshapes one post for each platform.
Your keys stay in your browser and never touch a server. If a model name changes upstream, the request heals itself, so a draft never fails on a renamed model.
Share and planner
Plan the rollout, stay in control of every post
Queue posts for LinkedIn, Instagram and X, tune the wording per platform, and mark each one shared once it is out.
Nothing posts automatically. The planner lines up the work, and you always press the button.
Publish
One click, one commit, live on a blog you own
Publishing writes a single atomic commit to your own GitHub repository. A Pages Action builds the site and your post goes live at your own address. No middle server ever holds your words.
