Inline editing for HTML and Markdown. Export your corrections as agent-ready instructions a model can learn from.
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.
Watch the three minute walkthrough.
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.
As a Chrome extension. 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.
Add Ryker to Chrome
from the Chrome Web Store, or load it unpacked from
extension/.
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- 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
npx --yes @gbti/ryker insert ./report.htmlPreview 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.htmlinsert 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.
This repository is at version 0.2.5, and the npm latest tag serves it, so
every npx command above installs this code.
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.

This credit lives here and in the Chrome Web Store listing, and deliberately nowhere else. Earlier commits placed it more widely and were narrowed later, so a commit message asking for it in other files has been superseded by this line rather than by an oversight. CC BY attribution attaches to distribution, and both places it appears are distributed: this file ships in the npm package, and the listing is public.
