OpenAI targets domains using 'GPT'

If you bought a clever domain name with "GPT" in it hoping to launch an AI side project, OpenAI's brand police might already be on your trail.

A developer recently shared on Hacker News that they received a cease-and-desist style outreach on behalf of OpenAI. The kicker? The domain, structured like gptsomething.io, was literally just a blank web page.

The email came from BrandShield Ltd., a brand protection agency hired by OpenAI. It warned the domain owner to change course or face escalation, setting a response deadline of 05.10.2023.

Drop it from the title, tuck it into the description

According to the outreach email, OpenAI is strictly enforcing its brand guidelines to avoid consumer confusion. The message pointed directly to a registered trademark for "GPT" listed in the WIPO database in Switzerland.

The agency explained that putting "GPT" in a site name or product title implies a direct endorsement or official partnership that simply does not exist.

So what can builders using the API actually say? OpenAI laid out clear ground rules.

You cannot use model names in your product name or domain title. However, inside your product description, you are permitted to say "Powered by GPT-3", "Powered by GPT-4", or "Powered by ChatGPT".

There is another crucial catch: developers must name the exact model they use. Simply referencing "GPT" in isolation is explicitly barred.

Blank pages under the automated microscope

What makes this incident stand out is that the target wasn't a lucrative scam or a phishing portal. It was an empty domain that had not launched any product yet.

This shows that OpenAI and BrandShield are actively running automated scrapers across domain registrars. The moment a domain with GPT hits the web, it triggers enforcement mechanisms before the creator even writes their first line of frontend code.

Why it matters

For indie hackers and developers, the gold rush of riding OpenAI's organic SEO waves is officially over. If you are building a wrapper, micro-SaaS, or utility, relying on "GPT" in your URL or app name is now a genuine legal liability. You will need to build an independent brand from day one.

For the broader industry, this highlights OpenAI's aggressive push to turn an open technical acronym into proprietary intellectual property. Generative Pre-trained Transformer is an academic architectural term, yet OpenAI is determined to lock down the acronym in consumer minds.

We think this strategy is a double-edged sword. On one hand, shutting down copycats protects everyday users from shady impersonators and subscription traps. On the other hand, unleashing corporate enforcement agencies on blank developer pages feels unnecessarily heavy-handed, especially toward the indie community that helped propel ChatGPT into a cultural phenomenon in the first place.
