As of July 2026, Monday.com holds 24.7% of ChatGPT ad placements in the AI Writing & Content Tools niche, despite selling project management, not AI writing. None of the top 5 advertisers in the category sell AI writing software. Work management, resume, and newsletter tools are monetizing the demand the vendors themselves are not buying.
Monday.com, a project management platform, owns nearly 1 in 4 placements in a niche it does not directly sell into. The category's own vendors are absent from the top of the leaderboard.

Top advertisers in AI Writing & Content Tools, ChatGPT
Monday.com is running at roughly 10x the average placement count, a deliberate outsized bet on a niche adjacent to its core work-management product. The auction is treating 'AI writing' as a horizontal workflow lane, not a category-defining one. Resume tools like BeamJobs and Resume.io each pull 3 placements, while no AI writing vendor on the leaderboard is buying at all.

THE UNCLAIMED DEMAND
The branded demand sitting unclaimed
What people actually ask ChatGPT6 real prompts
“adcreative.ai pricing plans explained is the agency tier worth it
“anyword vs writesonic for short form ad copy
“airops content workflow review from real agency operators
“best ai detector 2026 for teachers gptzero vs originality vs copyleaks
“best ai tool for cold email sequences that don't sound like ai
AdCreative.ai has zero placements in the captured set despite its pricing prompt appearing in the top queries. Anyword and Writesonic are both absent despite their head-to-head prompt showing up on the list. AirOps has no placement despite its review-style prompt appearing. Three branded queries, zero branded spend.
What this means for an AI writing vendor
You don't need to outbid Monday.com for the broad lane. The defensible play is to own a single sub-cluster where prompts already exist and no incumbent has shown up: AI detection, grammar for non-native English, cold email sequences, or governed brand content in regulated industries. The window is open because the auction is unusually thin, and it will not stay open once more workflow tools follow Monday.com in.
