ChatGPT's customisable personas changed how I start conversations and they are being widely overlooked

The customisable personas via the Voice tab are the feature most coverage glosses over. Being able to adjust the AI's tone and personality means a persona calibrated for technical documentation produces meaningfully different output from one set for casual copy, even on identical prompts. For people doing varied writing work that is not a minor tweak.

The sidebar redesign is genuinely useful rather than cosmetic. Managing multiple concurrent chat threads through the previous interface was friction that built up slowly. A dedicated sidebar that makes navigation between threads fast changes how you work when several things are running simultaneously.

The improved context retention across a long conversation is real and noticeable in practice. Earlier versions had a drift pattern where the model would lose thread of earlier constraints as the session extended. The improvement holds context more reliably which matters more than the interface changes for daily use.

The message feedback options being more accessible are worth using deliberately. Training the model on which responses worked for you only improves future responses if the feedback mechanism gets used consistently.

Are you using different personas for different types of work or finding one default that covers most of what you need?
