Once you have a saved analysis, the Improve panel rewrites your copy for personas you choose. Each saved analysis can hold up to 3 variants — different angles, audiences, or appeal types — that you can compare side-by-side. Variant 1 is free; variants 2 and 3 each cost 1 credit. The cap keeps you focused on the strongest 1-3 directions rather than infinite tweaking.

Anonymous analyses expire after 24 hours to keep storage manageable. Spending 1 credit converts the analysis to permanent: it stays in your "My analyses" dashboard forever, and you can come back, generate variants, or share the link. If you want the result, save it.

Credits are flexible — they spend on saving, iterating, or bulk analyzing. The $25 deck unlock is per-variant and one-shot: it removes the paywall on a specific variant so you can see the full rewrite, judge narrative, all annotations, and download the presentation deck. You only pay for the variants you actually want to ship.

Yes — every saved analysis has a public URL (e.g. thatsbetter.com/a/<slug>) you can send to anyone. They'll see the same analysis you do. The Improve panel and dashboard are only visible to you (the owner).

No. Credits stay in your account until you spend them.

Lift = sum of positive persona-fit deltas, weighted by inverse of the original score. Lifting a Cold persona from 20 to 50 counts more than nudging a Hot persona from 80 to 85. Typical range: 0 to 150+. A high lift isn't always the goal — sometimes deepening appeal to your strongest personas (Sharpen mode) is the right move even though the numeric lift is smaller.
