Material tradeoffs
- Murph does not reproduce Exist's non-health integrations or its statistics dashboard. If you want to inspect the numbers yourself, Exist's dashboard-first approach may suit you better.
- Useful correlations need enough overlapping history. A statistical association is not proof of cause.
- Each attribute can use only one source at a time, so you may have to choose when services overlap.
- Exist deliberately avoids generative AI. That suits people who prefer a purely statistical interface and frustrates people who want open-ended explanation. Murph takes the opposite approach and makes conversation central.
- After the 30-day trial, Exist has one paid plan at $6.99 per month or $62.90 per year. It does not advertise a permanent free tier.
Common questions about Murph and Exist
How does Exist compare with Murph?
Exist shows what moves together across your connected services and custom attributes. Murph helps you think through a health question and stick with what you decide. Murph is not a more detailed quantified-self dashboard, and Exist is not an open-ended health conversation.
Does Exist use generative AI?
No. Exist says it uses traditional statistical analysis rather than generative AI. Its insights come from the attributes you track and the correlations between them, not from an open-ended assistant conversation.
How long does Exist need before showing correlations?
Exist needs at least three weeks of data for an attribute and recalculates correlations weekly. More overlapping history can improve confidence. Exist itself warns that a correlation cannot establish cause.
