Docus vs Ubie
Ubie is the zero-friction option: a free AI symptom checker with no signup, built by doctors, that runs a structured questionnaire in about three minutes. Docus is the ongoing-relationship option: a free tier plus Lite at $3.99 per month and Pro at $7.99 per month for more AI doctor messages and AI-interpreted lab results, with a separate $490 human second-opinion service. Use Ubie for a quick one-off check; use Docus if you want a persistent AI health assistant that also explains your test results. This comparison does not constitute medical advice; neither tool replaces a licensed clinician. No hands-on testing was done for this comparison.
