When did AI first come in home computer programs in the 1980s?
Research question: When did AI-based tools first appear in software sold to home or office computer buyers in the 1980s?
The records show that in 1984, Prolog-KABA was commercialized on MS-DOS, which greatly contributed to the spread of Prolog 4. By 1985, some personal computer software publishers were claiming their products had artificial intelligence or expert system capabilities, though others doubted that true expert systems existed 1. The first generation of commercial natural-language systems, also described in 1984, required mainframe computers and so was not yet suited to personal computers 6. The facts do not identify when AI-based tools first appeared in consumer or office software, so the question is only partly answered 2.

The document says that in recent years the share of expert systems being developed on microcomputers has grown, citing a 1990 source, but it does not say when AI-based tools first appeared in consumer or office software.

Prolog-KABA was commercialized on MS-DOS and greatly contributed to the spread of Prolog.
"この処理系は MS-DOS 上で製品化されて Prolog の普及に大きく貢献した。"Prolog

Prolog was expected to become a base language for business software on early personal computers, but this did not happen because Prolog-KABA only handled 16-bit integers and could not handle floating-point numbers.
"Successful pop や末尾再帰の最適化など高い安定した性能で黎明期のパソコン上のビジネスソフトの基礎言語としての展開も期待されたが、16ビットの整数しか持たず、浮動小数点数も扱えない仕様であったため、この分野への展開は起こらなかった。"Prolog

The first generation of commercial natural-language systems required mainframe computers with large amounts of storage and processing power, so they were not yet suited to personal computers.
