Gemini dated their 110-year-old house from the ceiling, in 10 minutes
A six-pointed star and an ornate frieze on the ceiling. Gemini placed the frieze in the 1901-1910 period, which dated the house in about 10 minutes instead of hours of searching.

Matched to the original Federation Star
“Gemini told me that the frieze details were typical for the 1901-1910 period, and this helped me date the house.”

What they did
Lives in an Australian house at least 110 years old with many original details, including a six-pointed star on the ceiling. Asked LLMs about it, and one explained it matched the original Federation Star, which had six points before a seventh was added. Gemini said the frieze details were typical of the 1901-1910 period.
How it went
That helped them date the house in about 10 minutes, where it would have taken at least several hours of Googling before.

For each detail, tell me the style and the period it's typical of, and what that suggests about when the house was built. Say how confident you are, and which records (council archives, title deeds) I could check to confirm.
