caht is a typo. Here's the chat.

So, what does “caht” actually mean?

Nothing. “Caht” has no entry in the Merriam-Webster dictionary or any other respected lexicon. It's the fingerprint of a very common typing slip: your right index finger hits ‘h’ a millisecond before your left pinky can get to ‘a’ — and you've just spelled chat wrong.

Research from the CHI 2019 study on mobile typing errors found that letter transpositions account for 38.4% of uncorrected keyboard mistakes — the largest single category. Short, common words with adjacent-fingered letters (“chat,” “what,” “that”) get transposed the most.

“High-frequency words are more susceptible to transposition errors because they're typed faster — users rely on muscle memory rather than visual confirmation.”

Bottom line: if you typed caht, your brain wanted chat. And chances are you wanted to talk to an AI.

What is AI chat, and why does everyone suddenly want it?

AI chat is a conversational interface powered by a large language model (LLM). You type in plain English; the model responds in plain English. Under the hood, models like GPT-5, Claude Sonnet 4.5, and Gemini 3 Pro have been trained on trillions of tokens of text and code, and fine-tuned with reinforcement learning from human feedback.

As of early 2026, according to Pew Research, over 58% of U.S. adults have used an AI chatbot, up from 18% in 2023. Enterprise adoption grew even faster — a McKinsey 2025 State of AI report found that 78% of organizations now use generative AI in at least one business function, up from 55% a year earlier.

People use AI chat for: writing emails, summarizing long documents, debugging code, learning new subjects, drafting business plans, translating languages, and planning trips. The consumer AI chat market was estimated at $7.76B in 2024 and is projected to hit $46B by 2030.
