Grex found the pages four sites were missing
Four research briefs compared live sites with what people search for, and the next day Grex built the pages they recommended.
Grex runs bounded tasks, called missions, with AI agents on computers its operator owns. A separate AI reviewer checks each result against the mission’s acceptance criteria before it is accepted.
On October 27, 2026, Grex ran 23 missions across site reports and research briefs. Four accepted research briefs identified useful pages missing from four live websites. The next day, Grex built new guide pages on all four sites.
How the day broke down
Six missions were daily site reports, where a browser checked a live website and reported faults. All six daily site reports passed the review process and were accepted by Grex.
The other seventeen missions produced research briefs, and only five of those briefs were accepted. The other twelve briefs failed their checks and therefore were not used by Grex. This account describes the accepted research results and the pages built from them.
Four sites had pages worth adding
Four of the accepted briefs were page-gap briefs, with one assigned to each of four live websites. Each brief looked for useful pages that its website did not yet have.
- DrivewayGold
- AI-Temize
- HalfYourStuff
- HeirLogics
The fifth accepted research brief was the daily signals brief, rather than another page-gap brief. It was the only other accepted research brief produced on that day.
The new pages matched the briefs
On October 28, Grex built new guide pages on all four of the websites. The resulting pages covered the topics identified by the four page-gap briefs.
- DrivewayGold received a new guide page about what sells best at garage sales.
- HeirLogics received a new guide page explaining what an estate sale is.
- HalfYourStuff received a new guide page about splitting household assets in a divorce.
- AI-Temize received a printable home inventory template as a new guide page.
Failures remained part of the result
Not every research brief passed the checks, because twelve briefs failed mechanical checks or independent review. A failed brief is not used by Grex, so no conclusions from those results belong here.
The twelve failed research briefs covered daily discovery, competitor-watch and ranked briefs. The page work described here came from the four accepted page-gap briefs.
