Agentlet demos

Added it before 2 October 2026? Drag it again once so it picks up new demos within a day.

Most browsers show the bookmarks bar with Ctrl+Shift+B (Windows and Linux) or Cmd+Shift+B (macOS). This bookmarklet is separate from the one on the bookmarklet page, which only works on agentlet.io.

Supported sites

• Wikipedia

  Article pages on any language edition (*.wikipedia.org/wiki/...).

  • Tables to spreadsheet. Finds the infobox and every table of the article, previews them, and exports them to Excel.
  • Date timeline. Finds the dates in the article text and builds a chronological timeline, as a list and as a visual view, that scrolls to each passage.
  • Copy a company as a record. Reads a company article or Wikidata item and copies it as a structured record, ready to paste into a supplier form on a page that runs agentlet.

  Examples: Apollo 11 on English Wikipedia, and Danone on English Wikipedia.

• Wikidata

  Item pages (www.wikidata.org/wiki/Q...). Only the company record demo runs here.

  • Copy a company as a record. Reads a company article or Wikidata item and copies it as a structured record, ready to paste into a supplier form on a page that runs agentlet.

  Example: Danone on Wikidata.

• arXiv

  Listing and search pages (arxiv.org/list/..., arxiv.org/search/...), and abstract pages (arxiv.org/abs/...).

  • Papers to spreadsheet. Finds every paper on a listing or search page, previews them, and exports the ones you tick to Excel. On an abstract page, shows a citation line.

  Example: Recent papers in cs.AI on arXiv.

• Standards and regulations (W3C, RFC Editor, EUR-Lex)

  W3C Technical Reports (www.w3.org/TR/...), RFCs on rfc-editor.org (www.rfc-editor.org/rfc/rfc<number>.html), and EU legal texts on EUR-Lex (eur-lex.europa.eu/eli/... and /legal-content/...).

  • Spec to checklist. Extracts each requirement of a W3C, RFC or EUR-Lex document into an audit checklist with a status and a note per row, and exports it to Excel.

  Examples: WCAG 2.2 on W3C, RFC 9110 (HTTP Semantics) on RFC Editor, and The GDPR on EUR-Lex.

What the demos do and do not do

• They only read the page you are on. They never post, vote, reply or change anything on the site.
• There is no AI call and no backend. Excel files are built in your browser. Nothing is sent anywhere, apart from the lookup described in the next point.
• The company record demo writes to your clipboard when you click Copy. It also asks the public Wikidata API for one or two facts about the company on the page, the SIREN or the country of its headquarters. That request names the Wikidata item and nothing else.
• Closing the panel removes the marks and highlights the demos added to the page.

Limits

A site's Content Security Policy decides whether a bookmarklet can run. On checking, on 30 September 2026, the policies of GitHub, MDN, Stack Overflow and YouTube do not allow scripts that a bookmarklet adds, so nothing starts there. Hacker News restricts scripts to its own domain and a few others, which also blocks a script from jsDelivr, so it has no demo. Wikipedia, Wikidata, arXiv, W3C, RFC Editor and EUR-Lex allow scripts from jsDelivr, which is why they work. The markup of arXiv, W3C, RFC Editor and EUR-Lex pages is read as it is today, and may change. These policies can change at any time.

Bare four-digit numbers are read as years only when a word or bracket before them says so, and some numbers will still be misread. The timeline covers English, French, German, Spanish and Italian month names. It needs a recent browser.

How it is built

The bookmarklet loads a small script from the @agentlet/demos npm package through jsDelivr, which then loads agentlet-core and the demo for the page from the same exact version. Read how the known-site demos are built and hosted, including how to add a site.
