ChatGPT Now Has Two Very Different Modes — Here’s the One Most People Are Still Ignoring
If you’ve opened ChatGPT recently, you’ve probably noticed a new option sitting next to the usual chat window: a switch between Chat and Work.
Chat is the ChatGPT you already know — quick questions, quick answers, a conversation you stay in the loop for throughout. Work is something different: you hand it a brief, it goes away and works through it on its own, and it comes back with finished files rather than more text for you to assemble.
Here’s what’s actually changed, a real example of Work in action, and the one thing worth checking before you trust what it hands back.
Chat hasn’t got any weaker
Worth saying plainly: Chat still works exactly as it did before. You can still ask complicated questions about code or process, still upload files and talk it through, and it behaves exactly as it always has. Think of Chat as the space for simple, quick conversations — nothing more has changed there than the name of the tab it sits in.
What Work actually does differently
Work is for handing over an actual piece of work rather than asking a question. Give it a list of tasks and it goes away and spends real time on them — minutes, sometimes hours — and only reports back once the whole thing is done.
A real example: turning a folder of receipts into a finished expense register
The clearest way to see the difference is a real task. A folder of 24 receipt photos, taken on a phone, with a mix of currencies and a few better shots than others, was uploaded to Work with a single brief: build an expense register in Excel, break the receipts down by category, flag whether each was a business expense, sort everything, and produce a one-page expense summary document ready for a bookkeeper — plus a quick summary of what it found once it was done.
That’s a lot in one go — several distinct asks bundled into a single brief, not one simple question. In Chat, this kind of request would likely get a good effort, but risks giving up partway through or producing something generic. In Work, it’s treated as a single job to be worked through properly.
Once set going, there’s no need to sit and watch it — that’s the point. It opened the zip file, found the 24 receipts, and began extracting the details from each one. A few minutes in, it had sorted everything by month and started building the spreadsheet, with a visible plan on screen showing each step and its progress. After 11 minutes, the task was complete.
What came back
The finished expense register listed every receipt by date, with amount, currency, and category, plus a confidence indicator on how sure it was about each entry. A summary tab totalled the receipts flagged for review and the cost broken down by month. Alongside it sat the expense summary document — the kind of thing you could hand straight to a bookkeeper, flagging anything that needs a second look.
That’s the actual distinction between the two modes: Work did work on your behalf, rather than answering a question. It’s work that would otherwise take real time to do by hand.
Check it before you send it on
As with anything AI produces, the output still needs a look before it goes anywhere — the same discipline you’d apply to any piece of work you didn’t do yourself, before it reaches a client or a bookkeeper.
Browser, desktop, and the wider AI landscape
The example above ran entirely from the browser — no separate app needed, though Chat and Work are also available in the ChatGPT desktop app, which has long been solid at working with files like this. Claude and Gemini have their own equivalents of this — Claude Cowork is close to a direct match for ChatGPT’s Work mode, and Gemini has its own version too.
The simple rule
If it’s a quick question, use Chat. If it’s an actual piece of work — something that needs to run on its own and might take a while — use Work.
Which plans include Work
Work is available on ChatGPT’s paid tiers. At the time of writing there’s also a free trial available on free accounts, so it’s worth trying even without a subscription. For tasks like the one above, it’s a genuine time-saver.
