Ryker - Inline HTML & Visual Markdown Editing

Ryker

Ryker is a Chrome extension for editing a document in place and recording every change you make as a prompt-ready change request. A model can draft a report in seconds. What it cannot do is know that the third section should have come first, or that a summary buries its own conclusion. Those corrections are structural and they are yours, and the usual place to make them is back in the prompt, describing a document you are looking at but cannot touch.

Why inline

HTML has become a useful format for delivering rich content when working with large language models: complete reports, tables, figures, layouts and styled documents, in a form that renders immediately in a browser. Markdown has likewise become a common format for structured content.

Both are easy for a model to generate and awkward to edit at the source. Markdown means switching between source and preview. HTML source separates the author from the rendered document the reader will actually see. Inline editing lets you work against the rendered result instead, and Ryker keeps a record of what you changed while you do it.

Two ways to use it

As a Chrome extension. Install it from the Chrome Web Store, then click the toolbar button on any HTML page to edit that document in place. Or open the Ryker workspace and load a Markdown or HTML file from your own disk. On a tab Chrome will not let it touch, a new tab or a chrome:// page, the button opens the workspace instead of failing.

As a drop-in. Add Ryker to an HTML document with npx and it travels with the file. A reader or reviewer can then edit the page and produce a change request without installing anything.

npx --yes @gbti/ryker insert ./report.html

Features

• Inline visual editing for HTML and Markdown

• Export content changes as a machine-readable prompt

• An outline built from the document’s real heading structure

• Move or delete whole sections from that outline, recorded as moves rather than

  as character diffs

• Revision history tracked per document

• Markdown with nested lists, tables and code fences, returned as the file it came from

• Save the edited document back over the file you opened, or as a new file beside it

Install into an HTML document

npx --yes @gbti/ryker insert ./report.html

Preview first with --dry-run. The installer creates a recoverable report.html.ryker-backup, copies the dependency-free browser bundle beside the document, and adds one identifiable managed block before </body>.

npx --yes @gbti/ryker doctor ./report.html
npx --yes @gbti/ryker sync ./report.html
npx --yes @gbti/ryker remove ./report.html

insert writes Ryker into the document. doctor checks an existing install and writes nothing: it verifies the managed block is present and correctly placed, and that the bundle matches this version of the package. sync updates an existing install. remove deletes the managed block from that document and retains the browser bundle, because other documents in the same folder may share it.

Ryker requires Node.js 20 or newer for installation. The resulting HTML and classic browser script work offline and from file:// without Node.js.

Privacy

Ryker keeps its editing history in your own browser and sends nothing anywhere: no server, no account, no sync, no telemetry. The page cannot read it. You can export the record whenever you like and clear it per document.

The extension asks for no standing access to your browsing. It has no host permissions, registers no content scripts, and injects nothing until you click its button. The permission it uses, activeTab, grants access to one tab for one gesture and expires with it.
