A worked example

A small example to try before using your own data.

Input

{
  "draft": "Lee said, \"Revenue doubled in 2025.\"",
  "source": "Lee: Revenue grew by 20 percent in 2025."
}

Expected result

{
  "status": "mismatch",
  "quote": "Revenue doubled in 2025.",
  "source_words": "Revenue grew by 20 percent in 2025.",
  "correction": "Use the source wording, or paraphrase the 20 percent increase without quotation marks."
}

What to check: Flag the numeric difference and preserve the source wording; an inaccessible source is unverified, not confirmed false.

Limits: Search snippets and secondary repetitions are not substitutes for the original source.

Worked example included. Model-specific performance and vendor compatibility have not been benchmarked.

🧠 Why it works

Flag the numeric difference and preserve the source wording; an inaccessible source is unverified, not confirmed false.

⚙️ How it works

Extract every direct quotation and the person, date and publication attributed to it.

Locate the exact wording in a primary source; preserve a page, timestamp or stable link.

Distinguish exact matches, disclosed omissions, paraphrases and unsupported quotations.

Check whether surrounding context changes the meaning and whether the named speaker is correct.

Offer a supported correction without silently rewriting someone’s words inside quotation marks.
