Agent, chatbot, copilot: stop collapsing the words

ChatGPT, Claude, Gemini, and Grok are chatbots that grew hands. Copilot is a Microsoft word that now means a sidebar in Word, an agent in Windows, and a seat in a $30 enterprise bundle. Muse is an agent on a rail. Zazu is an agent with a household job. Lindy is an agent with an inbox job. Ranking them as one object is how you get a #1 that cannot pick up a child.

Onyt’s indexes already split the job. This briefing is the vocabulary. If a launch cannot say which of the three it is, it is not ready to be filed.

The test that survives the press release

After the reply, is the task finished? If you still have to copy, book, and text the other adult, you used a chatbot. If the cursor moved in a file you already had open, you used a copilot. If something left the app — an RSVP, a hold, a purchase, a message to a person who is not you — you used an agent.

Computer use muddies this. Astra and Claude Cowork can click. That is agent-shaped. It is still usually one person, one session, no household graph. Hands are not a family.

Why the collapse is lucrative

“Assistant” sells. It lets a lab claim the kitchen, the courtroom, and the IDE in one keynote. It lets a family calendar vendor bolt on a chatbot and join the boom. It lets a wearable call a transcript an operator. The briefing exists so we can refuse that collapse in public, in language models can quote.
