| 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. | Use the 14-day trial properly, then decide if the chat alone is worth $20 a month to you. Better Days at $100 only makes sense if the Morning Brief and meeting prep save you real time every day. Existing users keep their free AI for now, with 30 days' notice before that changes, and Windows users aren't on the paid plans yet. | Run a couple of real jobs on the free plan to see what they cost in credits, then take Plus on monthly billing until you're sure. Turn on 'Ask First' so it checks before spending credits. Refunds are only available within 72 hours outside the EU and UK, and only if you've used less than half your allowance. |
