Whoop is a sensor with an app. Cuilvor is a coach with no sensor. Whoop measures strain, sleep and recovery better than almost anything on a wrist - but it only sees what the strap sees. It doesn't know what you ate, what your ferritin's doing, or what your GP flagged in March. Cuilvor's whole job is the layer above: read everything - wearable data, meals logged in a sentence, blood panels from any lab - and write you one short weekly review with the one or two changes that matter.
The honest framing: if you own a Whoop, Cuilvor makes it more useful. If you don't, Cuilvor works anyway - you can log sleep and training in plain words.

No - they do different jobs. Whoop is a measurement device; Cuilvor is the coaching layer that reads measurements from any source (Whoop included), plus food and blood work, and tells you what to change each week.
Whoop's official API can feed Cuilvor's database; until you connect it, you can log sleep and recovery in plain language and Cuilvor parses it.
No. Cuilvor works from what you tell it and any lab results you share. Wearables just remove the typing.
No. Cuilvor tracks, trends and flags out-of-range values for a conversation with your GP. It never diagnoses or prescribes.
Your data is already telling the story. Cuilvor reads it.
