| Which plan to pick | Try it on Plus with a couple of real jobs. If you hand it work most days you'll run out of credits, and that's when Pro or extra credits make sense. | Stay on free. The side panel, tab comparisons and Journeys cover what most business owners need, and they cost nothing. Microsoft 365 Premium is only worth it if you're in the US and already want Office for the household; don't buy it just for the browser agent, which Microsoft still calls experimental. | Use it free: the sidebar assistant alone is worth having, and most people never need more. Pro makes sense if you want Perplexity's research tools anyway, but don't buy it just for the browser agent, since Pro's credits are a one-off bundle. Nobody needs Max just for the browser. |
