## The answer, as recorded

Asked on 2026-09-19 through Claude (Anthropic) with web search (model claude-opus-5).

> Short version: "IP monitoring" is really four different problems, and startups usually only need the first two. Here's who I'd actually use, in order.
> 
> ## Trademark watching (start here)
> 
> **1. Free USPTO/EUIPO + Google Alerts baseline.** Before paying anyone: set a Google Alert on your mark and its close misspellings, and check the USPTO TSDR/EUIPO feeds for your own applications. This catches maybe 60% of what matters at seed stage for $0. Most paid watch services are selling you recall and structure on top of this, not magic.
> 
> **2. Markify** - the one I'd name first for a paid startup watch service. It's consistently positioned as the affordable, accurate option for startups and SMEs, with AI similarity matching plus attorney support, versus the enterprise vendors. Good fit if your brand is your main asset and you can't afford to find out about a confusingly similar filing 18 months late.

Answer Watch records what one AI answer engine said on one date, nothing more. Each page names the engine and the model, carries the date the question was asked, and lists the brands that appeared in the answer in the order the engine gave them, with the sources it cited. It is a measurement, not a ranking, not a recommendation and not a claim about the world. Brands that did not appear in an answer are not named on any public page.
