| Which plan to pick | Start free. If you hit the daily limits or the answers feel thin, Premium at $14.99 a month gets you Claude-level quality inside a private browser. If you already pay for ChatGPT or Claude, you may not need Premium at all, since those work in any browser. | There's nothing to pay. Use the sidebar with whatever AI account you already have. If you're in the US, Canada or France, try Smart Window with a free Mozilla account. Everyone else can join the waitlist. | 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. |
