Editorial read

By Ryan York · September 2026 edition · 25 runs · 25 prompts

Twenty-five prompts, one run each, from ChatGPT with web search. Property Meld was named in 91% of runs, Lula in 65% and Latchel in 64%, and all 12 vendors in the database were named at least once, the smallest field of the three categories. The most-cited domains were latchel.com, propertymeld.com and lula.life, and Property Meld's documentation subdomain drew 17 citations on its own. A support site earning that many citations suggests the engine reaches for product documentation when a prompt asks how something actually works. Treat the ranking as a first reading; the full protocol is three runs per prompt per engine across at least two days.

Ranking

Maintenance & Vendor Network Software, September 2026. Mention rate = share of runs that named the vendor, averaged over engines that answered (1 of 4 this edition). Rank by mention rate. Consistency = share of prompt×engine cells where all runs agreed; shown as – with fewer than two runs. Movement vs the prior edition; – when there is none. Green means named.

Every vendor in the category database is listed, named or not. A vendor that is absent from every answer is still a row, because absence is the finding. Add or correct a vendor.
