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
- Token streaming — silence feels broken once users have seen streams elsewhere.
- Stop button — control is part of trust.
- Step or tool disclosure — especially for agents; keep it skimmable.
- Immediate ack — something changes the frame as soon as you submit.
Patterns to adapt carefully
- Long chain-of-thought theater — can overwhelm; summarize for prosumer UIs.
- Playful filler copy — ages poorly in serious workflows.
- Heavy brand mascots — fine for consumer chat, noisy inside an IDE.
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.
