Sample decision
A card can look profitable in PSA 10 but lose money in PSA 8 or PSA 9 once grading, shipping, insurance and selling fees are included. Kardive makes that spread visible.

| PSA 9 | $980 | +$92 | +9% |

| PSA 7 or lower | $520 | -$318 | -30% |
What the demo teaches
The demo shows the shape of the decision: start with card identity, add costs, read the best and worst grade outcomes, then decide whether the full app is worth using for live cards.
- Card identity
- Cost model
- Grade spread
- Risk label
Where the demo stops
The public demo is intentionally limited. The authenticated app adds saved scenarios, watchlist actions, alerts, portfolio context, exports and full calculator detail.
- Saved decisions
- Watchlist
- Alerts
- Portfolio
