Read the sample passage (269 words, set in June 1962, outside New York)

It was the second week of June, 1962, and the kitchen was hot by eight. Nan folded the two pages twice, creased them with her thumbnail, and got them into the envelope before she could read them over and lose her nerve.

She wrote the zip code from memory, the way you do with a street you have known since you were small. Then the stamp, eight cents, pressed down harder than it needed to be.

Mrs. Vance had her radio in the window again. "Please Please Me" for the third time before nine, and the sound came down the drive after Nan like something she had forgotten to put away. She walked to the box at the end of the road with the envelope held out from her side, the way you carry something you have decided not to think about.

A plane went over low on its way out of Idlewild, one of the new 727s, and she stopped in the gravel to watch it the way she still stopped for planes. Her mother had done that. It was the one thing of her mother's she had not managed to put down.

The walk back took longer. It always did. By the time she reached the porch the heat had come up off the road and the morning had that flat white look it got before noon, and her father was awake and wanting his coffee and the television on for The Fugitive, and she would sit through it beside him the way she sat through most mornings now, waiting for something in the room to change.

6 real-world claims checked in 269 words. The checker is an AI: a large language model that searches Wikipedia and the web for evidence, judges each claim against it, and sends every problem it finds to a second pass, the Skeptic, which argues against it. These cards are the ones that survived, saved from one real run on the sample passage.

“She wrote the zip code from memory”
The evidence consistently establishes that the five-digit ZIP Code was introduced on July 1, 1963, so ZIP codes were not yet in use in June 1962.
contradicted92%
“Then the stamp, eight cents”
The USPS rate table shows first-class postage was 4 cents from August 1, 1958 until January 7, 1963, so in June 1962 the rate was 4 cents, not 8 cents (8 cents took effect May 16, 1971). DollarTimes independently confirms a 4-cent first-class stamp in 1962.
contradicted70%
“"Please Please Me" for the third time before nine”
Evidence shows 'Please Please Me' was only written by John Lennon in June 1962 and not released until later, its UK release was 11 January 1963 and its US release was February 1963, so it could not have been played on US radio in June 1962.
contradicted95%
“one of the new 727s”
The Boeing 727 first flew on February 9, 1963, and entered commercial service on February 1, 1964, so it was not in service in June 1962 (its prototype was not even rolled out until November 27, 1962).
contradicted95%
“the television on for The Fugitive”
The evidence establishes that 'The Fugitive' premiered in the United States on September 17, 1963 (on ABC), not in June 1962; the series ran from 1963 to 1967.
