New Sidebar Tools: Fact Checker, Second Reviewer & Site Search

I’ve added three new widgets to the sidebar to support reading and research on sarsen.org.

These tools are designed to help evaluate claims, review documents, and find relevant content on the site. They all use Grok, with prompts written to maintain high standards of evidence. Other AI tools are available and I would urge you to use them as well, Grok just produced the cleanest widgets and is very good at fact checking. Having detailed prompts prewritten improves the ease and accuracy of using AI agents.

1. Archaeological Fact Checker

This widget helps assess the strength of individual claims.

You can paste a URL or a block of text, and it opens a structured analysis that evaluates claims according to a clear hierarchy:

• Peer-reviewed papers as the highest standard
• Academic consensus
• Single-author assertions, which are examined using logical and Bayesian-style reasoning

It’s particularly useful when encountering claims in articles, social media, or discussions about Stonehenge, bluestones, sarsens, or Neolithic archaeology.

2. Second Reviewer

This tool is designed for reviewing papers and drafts.

It offers two options:

• Review Pasted Text — Paste a section or excerpt for a structured review covering the referenced science, logic, inferences, strengths, and weaknesses.
• Open Grok for PDF / Document Upload — Opens Grok with a detailed reviewer prompt already loaded. You can then upload a full PDF or document directly for a more thorough review. This version also provides suggestions for improvement when reviewing drafts.

It applies the same evidence standards as the Fact Checker, with a focus on peer-reviewed sources and logical rigour.

3. Search sarsen.org with Grok

This is a site-specific search tool.

Instead of a general search, queries are directed toward content on sarsen.org. It’s useful when you want to find posts or information on particular topics (such as specific monuments, papers, or debates) without leaving the site’s context.

How to use them

All three widgets are available in the sidebar. They are intended as aids rather than definitive answers. The quality of the output depends on the prompt and the material provided. As with any AI-assisted tool, it remains important to check original sources, especially peer-reviewed papers.

These tools are experimental and will likely be refined over time. Feedback on how they perform is welcome.
