| Which plan to pick | The free plan is enough to see if the speed and tone suit you. Pro is good value at $14.99 and a sensible second assistant next to Claude. Students can get Pro for $5.99 a month for up to 12 months. | 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. | For chat, it's free. Developers should start with Coding Plan Lite and code off-peak, because usage between 2pm and 6pm Singapore time on weekdays costs more credits. Move to Pro only if you hit the weekly cap. |
