Hinglish Is Where Generated Copy Still Fails
Most Indian advertising is not written in English or in an Indian language. It is written in the mix people actually speak, and generated copy handles that register worst.
The failure is not vocabulary. Tools have plenty of Hindi and a reasonable amount of several other languages. What they lack is the rule nobody has written down: which word stays English, which word must be Hindi, and where the switch happens in a sentence for it to sound like a person rather than a translation.
Why Generated Copy Gets The Mix Wrong
Because the mix is social rather than grammatical. A word choice signals class, city, age and how seriously the speaker is taking themselves, and those signals are learned by living somewhere rather than by reading a corpus.
The common failure mode is over-correction: the tool produces either an English sentence with two Hindi words dropped in for flavour, or full formal Hindi that nobody speaks in a metro living room. Both are instantly recognisable to an Indian ear and both make a brand sound like an outsider.
Getting the mix wrong does not read as a language error. It reads as a brand that does not know who it is talking to.
Where It Does Help
Volume work. Product descriptions, listing copy, subject lines and the fifteenth variant of a functional line are genuinely faster, and the risk of embarrassment is low because the register is neutral by design.
Transcreation briefs are another: getting a first pass into eight languages so a human writer in each one is editing rather than starting is a real saving, provided the editor is a writer and not a checker.
What Not To Do
Do not let a generated line go out in a language nobody on the team speaks. That is the single most reliable way to produce the mistake that ends up screenshotted, and it is entirely avoidable by keeping one native speaker as the last approval on every language, every time.
