| Which plan to pick | 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. | Try the Free plan for a week to get a feel for how many credits a real task uses, then move to the $20 Pro tier. Only go higher if you run out most months or you want it to publish websites for you. |
