One Amy, four depths.

Same Amy, same warmth. Higher tiers give you more chat each day and deeper, longer analysis when your decision calls for it. All four run on the same underlying AI. You're paying for capability and time, not a different Amy.

Yes. Change or cancel from Settings whenever you want, with no cancellation fee. Your subscription stays active until the end of the period you've already paid for, and your decision history and saved data stay with you.

All CostMe purchases are final. Cancel before your next renewal to avoid being charged again; your subscription stays active until the end of the period you've paid for. The free Jade tier lets you try CostMe before you commit. If something's broken or you can't access what you paid for, contact Support and we'll fix it.

One chat turn is one back-and-forth with Amy: you send a message, she replies. On Jade that's five thoughtful turns a day; Opal, Flint, and above get high daily limits, subject to fair-use limits so one person can't degrade it for everyone.

Yes. The way Amy frames spending decisions is built on decades of behavioral-economics work. That we feel a loss about twice as strongly as a gain of the same size, that the moment of tapping pay registers as a small loss, and that the pull of the smaller reward now tends to beat the bigger reward later. That grounding shapes every reply at every tier. On Flint and Flint Max, Amy can cite specific studies by author and year when they're relevant to your question.

You keep all your saved history. On Jade, Amy's daily chat drops back to 5 turns and her answers run a little shorter. Upgrade again any time and you're right back to high daily limits and in-depth replies.

We publish the roadmap openly at costme.io/roadmap. Anything listed under your tier arrives included, no price change.
