Which plan to pickGive most staff Standard seats and buy Max seats only for the few who use AI all day. Yearly billing saves about 20%, and seat prices drop with volume.Start free and see how often you hit the Pro search limit. If you research most days, Pro pays for itself in saved tabs. Its 4,000 bonus Computer credits are a one-off and run out after about 30 days, so don't count them as a monthly allowance. Max only makes sense if you're using the Computer agent heavily enough to burn through the credits.Start free; most people never need to pay. Go at $4 is cheap if you hit the chat limits. Prices are App Store prices, so check the in-app screen before you subscribe.
