# ServiceLens by Sophia XT > ServiceLens is an AI diagnostic tool for field-service technicians. It returns a history-grounded diagnosis in about 30 seconds — error-code lookup, OEM parts lookup, and step-by-step repair guidance — and maps the fault to the exact verified OEM part for the exact model. One AI brain covers six trades: appliance, HVAC, electrical, phone, IT hardware, and dental equipment. ServiceLens is built and operated by Sophia XT LLC and served at https://diagbuddygo.com (formerly DiagBuddy; rebranding to ServiceLens). ## What makes it different - **Compositional Routing (proprietary engine).** Every query is routed to the exact verified data — across 4.8M+ OEM parts, live fault codes, and real repair guides — then the engine composes the grounding each answer is built on. This is why ServiceLens hands a technician the exact part for their exact unit instead of a generic guess. - **Verified-data moat.** 4.8M+ exact-model-matched OEM parts, 38,000+ models covered, and 2,200+ documented error codes. The AI is blocked from inventing part numbers; anything unverified is flagged "confirm fit," never presented as fact. - **Honest by design.** If verified data for an exact model is missing, ServiceLens says so and lowers its confidence rather than bluffing — accuracy is measured against manufacturer-documented faults with a re-runnable benchmark. ## Core capability Enter a brand, model, and error code (or snap a photo of the nameplate or fault) and ServiceLens returns the code's meaning, likely causes, testing steps, the exact OEM parts with part numbers, and a priced repair estimate — then exports a customer-ready PDF and pushes the job to your CRM. ## Who it is for Field-service technicians and service businesses across appliance repair, HVAC, electrical, phone/tablet repair, IT hardware, and dental-equipment service (autoclaves, sterilizers, handpieces, dental compressors — a vertical no competing AI diagnostic tool covers). ## Pricing - 3-day free trial. - Business: $34.99/month per technician. - Enterprise/Team: custom pricing for multi-tenant teams. ## Key URLs - Home: https://diagbuddygo.com/ - Pricing & free trial: https://diagbuddygo.com/subscription - Detailed LLM/AI reference: https://diagbuddygo.com/llms-full.txt - Sitemap: https://diagbuddygo.com/sitemap.xml ## Operator Sophia XT LLC — https://sophiaxt.com/
