| Method | Deterministic same-day rules — RALLY, KEEP, BLEED, CUT — you can read line by line. | Learning models trained on your own account propose bids inside the deterministic envelope. |
|---|
| Pool of candidates | Narrow — built from your proven targets: seeded from your own data, sorted into history classes, then refreshed weekly with promotion/demotion. Spend-safety still covers any target. | Broad — every eligible target, including the long tail rules tend to leave alone. |
|---|
| Reacts to | Today’s spend and conversions so far — fast intraday reaction. | Learned demand patterns, including time-of-day dayparting, across the whole day. |
|---|
| Bid moves | Small, rule-bounded nudges on a per-tier cadence (2–6 runs/day). | Continuous, model-proposed moves on its own cadence — clamped to your caps. |
|---|
| Business value | Protects and presses same-day momentum on known winners — fast, surgical, fully explainable. | Squeezes value from the entire book and the clock — finds moves fixed rules miss. |

| Availability | Every paid plan (Starter, Growth, Pro). | Hosted Growth and Hosted Pro. |
