Which plan to pickStart 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.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.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.
