As answered by people managing JavaScript Operator Lookup and Guide.MD.
Guide.MD's answer:
Guide.MD gives healthcare providers direct control over their online identity — something most directories don’t allow. Each of the 6.7 million profiles is automatically verified from federal data, then claimable and editable by the provider. It’s built around accuracy, transparency, and physician ownership rather than anonymous listings or paid reviews.
Guide.MD's answer:
Unlike sites driven by ads or patient reviews, Guide.MD focuses on verified data and provider control. Professionals can update their credentials, contact info, and affiliations themselves, ensuring that search engines and AI systems display accurate details. Patients benefit from current, trustworthy information, while providers finally manage how they appear online.
Guide.MD's answer:
Guide.MD serves three main groups:
Healthcare providers — physicians, dentists, podiatrists, nurse practitioners, and therapists who want verified, editable profiles.
Hospitals and practices seeking accurate, SEO-ready listings.
Patients looking for reliable, up-to-date information about their providers.
Guide.MD's answer:
Guide.MD was created by a practicing physician who noticed that most doctor listings online were outdated, incomplete, or wrong. Instead of letting algorithms and data brokers control professional reputations, the goal was to build a verified, physician-first directory — one that physicians could claim, correct, and own.
Guide.MD's answer:
React – frontend framework for a fast, responsive UI
Next.js – server-side rendering and SEO optimization
Node.js / Nest.js – scalable backend services
PostgreSQL – structured database for provider records
ElasticSearch – faceted search across millions of profiles
Stripe – payments for premium and concierge services
Guide.MD's answer:
Independent physician practices
Multi-specialty clinics
Dental offices and DSO networks
Ambulatory surgery centers
Hospital marketing departments
Medical universities verifying alumni listings
