AI Shortlist Index, September 2026: Release

The finding

On the first maintenance prompt, ChatGPT named Property Meld first and recommended it, with Latchel second. Its answer leaned on Reddit threads and vendor sites, not review platforms.

Data note: this edition is below the full protocol (three runs per prompt per engine, four engines, at least two days). It rests on 1 recorded run from ChatGPT. Numbers are real and thin; treat rankings as a first reading.

The full tables are on the September 2026 edition snapshot; the live category pages carry the current edition.
