Clarity by Lumos Inspection

Frequently asked questions

Everything people ask us

Clarity reads a pre-purchase inspection report in PDF, checks every finding against the page that contains it, and delivers an analysis: rating out of ten, priorities, repair estimate, negotiation strategy. The answers below cover accepted reports, the method, estimates and the service.

01Reports

Which reports work?

Every residential inspection report in PDF, in French or English: Québec reports, InterNACHI, ASHI, TREC forms, and reports produced by Spectora, HomeGauge, Horizon, Home Inspector Pro, Enzo, Vesta or Lumos. Pre-delivery, condo and multi-unit reports work too.

What about a scanned report, as images?

Clarity reads pages as images and text at once, so a good-quality scan works. If the text is unreadable, the analysis will say so rather than make things up.

How long can it be?

From 10 to 250 pages. Beyond that, write to us.

What if it is not an inspection report?

Clarity detects it at the door (broker sheet, blank template, article, quote) and stops before analyzing. You are refunded.

02The method

How does Clarity read the report?

In seven passes, each with its own rules and model. 1. It identifies the report, its standard and its severity legend. 2. It reads every page a few pages at a time, in parallel, and captures each inspector finding with its page and exact sentence. 3. A verifier with no AI checks every quote against the text of the page; what is not there is dropped. 4. It classifies every finding on PRISM, Lumos’s building taxonomy (160 categories, 28 domains), and qualifies it under the BNQ 3009-500 grid. 5. It matches it against a bank of more than 1,150 findings written by Québec inspectors. 6. It merges repetitions (the summary, the detail sheet and the recommendation often describe the same defect). 7. It writes the analysis from those findings, and only from them, with domain rules and regional cost grids.

What do “observed”, “to confirm” and “limitation” mean?

That is the inspectors’ grid. Observed: the inspector saw the anomaly. To confirm: he saw a sign (a stain, efflorescence) without confirming the problem behind it; only a closer look will tell. Limitation: something could not be inspected (snow on the roof, stored items, panel not opened). ChatGPT, Gemini or Claude do not make these distinctions; they change everything for your decision.

Where does the rating out of 10 come from?

It is anchored on your inspector’s labels (danger, defect to correct, monitor, satisfactory) and on the weight of what must be fixed, not on the count of cosmetic items. The reasoning is written next to it. It is an assistant’s opinion to help you place the house, not a professional appraisal. Under the rating, “Understand the rating” details the 1-to-10 scale.

Does the AI make things up?

The reading is mechanically verified: a finding whose quote is not found on the stated page is discarded. Explanations, estimates and advice are then produced from those findings only, with the instruction never to add a fact about the house. We measure this on a corpus of real reports: recall of deficiencies, quotes found, stability from one run to the next.

Does Clarity contradict my inspector?

Never. It keeps his label and recommendation word for word, and it suggests questions to ask him. If you find a disagreement, the inspector is right, and we want to know.

03Estimates and advice

Are the amounts reliable?

They are orders of magnitude for your region and currency, for the most likely fix implied by the inspector’s recommendation, within roughly plus or minus 30%. When the report says a specialist must assess first, Clarity does not price it and tells you. Only written quotes count.

Is the negotiation advice serious?

It helps you prepare the conversation: what is reasonable to ask the seller, what is reasonable to accept, and the conditions under which walking away is wiser. Your broker and your notary remain your advisors.

What do I do with the next steps?

Follow it in order: call the inspector with the questions, get the documents and assessments before your inspection-condition deadline, then negotiate in writing. The roadmap then covers the first year.

04The service

How long does it take?

Three to six minutes depending on the report length. You watch the reading progress live, and you can close the page: an email tells you when it is ready.

How much does it cost?

One payment per report, $29, taxes included. Refunded if the file is not a readable inspection report.

Why pay, when ChatGPT, Gemini or Claude are free?

Because Clarity is not a chat. Every analysis chains seven passes and dozens of calls to frontier models, including a large model for reading and writing, then a quote verifier, a 160-category taxonomy, the BNQ 3009-500 grid, a bank of more than 1,150 inspector findings and regional cost grids. This engine is the result of more than a year of work with building inspectors, it is measured on real reports, and it is guaranteed. A free chat reads part of the document, verifies nothing and guarantees nothing.

What if the analysis is wrong, or useless?

We refund 100%. If you show us, with evidence, that Clarity got its analysis wrong, or that the analysis is not relevant to your report, write to us with the link to the analysis and the item in question. We check, and we refund the full amount.

Can I share the analysis?

Yes, by its link. The link is personal and not indexed.

My data?

The PDF is stored privately on our servers in Canada and used only for your analysis. It trains no model. Write to us to have it deleted, along with the analysis.

Who is behind Clarity?

Lumos, a Québec company that also makes Lumos Inspector, the report-writing application used by building inspectors. Clarity applies to the reports you receive what we learned helping inspectors write them.
