How ChatGPT, Claude, and Perplexity show thinking — and what to copy

A product teardown of thinking/streaming UX in major AI chat apps, and which patterns startups should copy without cloning the brand chrome.

Frontier chat apps educated the market. Your users now arrive with expectations about streaming, cancellable runs, and visible “working” states — even if they cannot name those patterns.

Patterns worth copying

Patterns to adapt carefully

What smaller products should do

You do not need to clone ChatGPT’s chrome. You need the underlying contract: submit → visible mind → stream or phases → settle. A compact companion plus a clean transcript often beats a cluttered imitation of a giant chat app.

Where Glim helps

Glim covers the “visible mind” slice with idle/thinking/talking/listening. Pair it with your own stream renderer and citations. That split keeps you differentiated where it matters (answers + workflow) while meeting baseline presence expectations.

Copy the contract, not the costume.
