Six trades, one brain

One app for the whole service truck.

Most diagnostic tools pick one trade. ServiceLens runs the same history-grounded engine across all six — including the one nobody else will touch.

Only on ServiceLens

Dental equipment

Chairs, compressors, autoclaves, handpieces. A dedicated dental corpus and built-in dental error codes — the trade no other AI diagnostic tool covers.

What's inside the lens

Not a chatbot.
A diagnostic instrument.

Four things every general-purpose AI gets wrong about a service call — and the reason techs trust the answer.

01

History-grounded, not internet-guessed

Every diagnosis you confirm becomes signal. ServiceLens retrieves your shop's real past jobs and weighs them against OEM data.

02

Live OEM parts + pricing

The exact part number and current price from Encompass and PartSelect — no tab-juggling, no guessing at a fitment.

03

2,200+ error codes decoded

Cross-checks the fault against a maintained error-code library across all six trades, including dental.

04

Customer-ready PDF reports

A branded report your customer trusts, generated in one tap — parts, pricing, and the work performed.

AI diagnostics · 6 trades

AI diagnostics across six trades

The same history-grounded engine runs appliance, HVAC, electrical, phone & tablet, IT hardware, and dental equipment — one brain for the whole service truck, not six single-trade apps.

The proprietary core

Not a generic chatbot — a model that knows this equipment cold.

ServiceLens runs on a proprietary diagnostic model trained and grounded on real repair data — not a general-purpose chatbot improvising from the open web. The brands and faults above aren't a marketing list; they're what the model is built around.

Put it to work on your next call
Grounded on a proprietary corpusProprietary data

Verified OEM parts, real fault histories, and a maintained error-code library across all six trades — the data the model is trained and grounded on, not scraped guesses.

NCN specialist modelsNCN specialists

Dedicated specialist components focus the model on each trade's equipment, so the answer is the named fault and the right OEM part — not a generic best-guess.

Sophia memory recallSophia memory

Semantic recall of real repair history surfaces the jobs that match the unit in front of you, so every diagnosis is weighed against what actually fixed it before.

Why ServiceLens

Why techs choose ServiceLens

Not a chatbot with a parts link, not a single-trade gadget, not a $15k platform. A grounded diagnostic brain that walks your tech to the fix — the exact part, the exact test, for the exact model.

vs. general AI (ChatGPT, generic tools)

It never invents a part number

A general chatbot answers from memory and guesses parts — wrong part, callback, wasted trip. ServiceLens routes every diagnosis to 1.96M+ verified OEM parts and hands back the exact part for the exact model, or says it isn't sure. Grounded, not guessed.

vs. single-trade tools

Every trade your crew touches

The deepest diagnostic rivals cover HVAC only. ServiceLens spans appliance, HVAC, electrical, phone, IT hardware and dental equipment — one grounded brain, so one tool covers the whole truck instead of a stack of them.

vs. the big FSM platforms

Specialist accuracy, tool pricing

The enterprise platforms charge per-tech many times our price, add five-figure setup fees, and bolt AI on as a general helper. ServiceLens is purpose-built for the diagnosis — with a built-in CRM and dispatch included — at a fraction of the cost and no implementation fee.

Exact-model grounding

1.96M+ verified OEM parts, 16,071+ models — matched to the exact unit, not a similar one.

Real test plans

Every diagnosis includes the ordered field tests — with the expected ohms / continuity readings — not vague advice.

It gets smarter every repair

A self-improving flywheel: parts your techs confirm fixed a symptom lead the next time that symptom appears.

Snap the nameplate

Photograph the rating plate and the model auto-reads — no typing a 14-character model number under a machine.

And we won't quote you a fake “99% accurate.” Our accuracy is measured on a re-runnable benchmark against manufacturer-documented faults — real numbers you can hold us to, tracked as first-time-fix and wrong-part rates with your own shop.

Measured, not marketed

Accuracy you can actually verify

Most AI repair tools are a generic chatbot with a parts link. ServiceLens is a verified repair-intelligence layer — every answer is grounded in real, model-verified data, and we test it instead of just claiming it.

Compositional RoutingProprietary engine

ServiceLens runs on Compositional Routing — our proprietary engine that routes every query to the exact verified data across 4.8M+ OEM parts, live fault codes, and real repair guides, then composes the grounding each answer is built on. It's why the model hands a tech the exact part for their exact unit, not a guess.

Calibrated confidence — no overconfident bluffing

From a re-runnable benchmark + routing verification against manufacturer-documented faults. Numbers grow as the corpus does.

Grounded, not guessing

Every diagnosis is backed by 4.8M+ exact-model-verified OEM parts and live fault codes. The AI is blocked from inventing part numbers — anything unverified is flagged “confirm fit”, never presented as fact.

Real repair guidance, not vibes

Layered grounding: manufacturer + iFixit verified repair guides and service manuals on top, real-world technician fixes below — so you get the documented fix first, corroborated by field experience.

Honest when it doesn't know

If we lack verified data for your exact model, ServiceLens says so and lowers its confidence instead of bluffing — then searches to add it. Trust beats a confident wrong answer on a service call.

Tested, not claimed

Accuracy is measured by a re-runnable benchmark against manufacturer-documented faults — auditable, and improving every week as the corpus grows. We show our work.

Compare

Built different: a grounded diagnostic engine, not an API wrapper with gimmicks.

Most "AI for trades" tools are a prompt around a general model — easy to build, easy to copy, and they guess the part number. ServiceLens puts the engineering into a verified corpus and exact-part grounding. Here is exactly where we sit, stated comparatively — not as beat-everyone hype.

No gimmicks

Deliberately silent — no voice, ever. That's a strength, not a missing feature.

A tech talking to an app in a customer's kitchen looks unprofessional and slows the job down. ServiceLens is text and diagrams only — a quiet screen a tech taps while staying in control of the room. We put the engineering into accuracy and the exact part, not into a talking gimmick. Voice demos well; a verified part number gets the truck back on the road.

vs Aquant

Aquant targets enterprise, expensive, complex industrial and medical fleets. ServiceLens is affordable and field-tech-first — appliance and HVAC for SMB shops, silent with diagrams, and a stronger office-to-tech prescreen that gets the part right before the truck rolls.

vs Aiventic

Aiventic leans voice-heavy on a leaner corpus. ServiceLens is no-voice, with a larger verified-OEM-parts corpus, exact-part grounding, a self-improving flywheel that learns from confirmed field fixes, and a built-in auto-estimate — the depth and the close-the-loop, not just the conversation.

vs general FSM

Housecall Pro, Jobber and ServiceTitan run scheduling, dispatch and invoicing — not diagnosis. ServiceLens is the complementary AI diagnostic brain they lack, and it pushes the diagnosed, quoted job directly into them (Housecall Pro + Jobber wired today; ServiceTitan is an FSM we push into, not a live integration).

vs manufacturer tools

OEM tools are locked to one brand and one portal. ServiceLens is brand-agnostic and far broader — one tool across makes, models and trades, instead of a different login per manufacturer.

4.8M+ parts · 38,000+ models · 2,200+ codes

ServiceLens is complementary to FSM platforms — the AI diagnostic brain they lack, that pushes work into them. Accuracy figures are from a re-runnable benchmark: 81% strict exact-component, 100% on common faults, 86% calibrated confidence — kept distinct, never blended.
