How Lehvel handles your data and its AI.

How we treat the businesses in our research, where the facts on this site come from, what our AI may and may not do, and what you can buy today. Where something is unfinished, we say so.

Updated

Businesses in our research stay anonymous unless they agree.

  1. Totals, not businesses. Customer data appears in our research only as anonymized totals. The September 2026 study covered four businesses, 25 AI answers and 135 claims. It names none of them and gives no figure for any one business.

  2. Named with permission. We name a business only when its owners agree. Our fieldwork page describes one company's results without naming it.

  3. What stays private. Supplier names, staff portraits, vendor quotes and screenshots of a client's tools stay off this site.

  4. Small samples stay small. Each Lehvel number comes with its method, sample and dates, and we don't stretch it past that sample.

Every fact has a source and a date.

  1. On this site. A research figure carries its source, its date and the day a person last checked it. After 120 days it shows as due for review.

  2. In a client's record. Each fact is marked confirmed, needs review, unknown, or stopped. It records who stands behind it, from the owner down to an inference, and when it was last confirmed.

  3. Observations. A website, a listing or an AI answer is evidence, not fact. When one disagrees with a confirmed fact, a person decides. The confirmed fact is never overwritten.

  4. “Supported” isn’t “verified”. In the September study, a supported claim matched a draft record built from the business's own website and Google profile. The owners hadn't confirmed it.

    Published research

  5. Fixes. A fix counts only when a later check confirms it, and the checker is never the one who made the change. Proven on a public listing.

What our AI may do, and where a person steps in.

Our software uses AI to read, sort and draft. A person answers for the result either way.

  1. Meeting notes. AI meeting notes are evidence, not fact. A person corrects them against what was said, and only then does a statement become a dated ruling with a name on it.

    In use

  2. Job photos. The AI sorts the photos, writes captions, blurs faces and house numbers, and proposes the change. A person approves it before anything goes live.

    In use

  3. Paper quotes. The AI reads a vendor quote into fields but never sets a price. A person checks every field. The tool can create an estimate and nothing else: no invoices, no payments, nothing sent to a customer.

    In useAt one office, still being tuned

  4. AI answers. The Lehvel Observatory records what the AI platforms your customers use say about a business and grades each claim. A person starts every run, and an answer never changes the business's record.

  5. Where changes land. The AI never chooses which client's website a change goes to. The target comes from the request, and an automated check guards that rule.

What is running, and what you can buy.

  1. Fieldwork website. One company's public site, checked on the live page.

  2. Meeting, photo and quote workflows. Running for a building-products company. We build the same kind of workflow for other companies in an engagement.

Business Truth Diagnostic

A written diagnosis of one business and its primary website, with a two-hour results review included. Research and recommendations only.

Contact Lehvel to discuss the scope.

About the Diagnostic

You can also book an initial discovery call, a working day or an engagement. Website updates by voice, and AI invoicing and estimating workflows, are built inside engagements. Existing clients keep the services in their agreements.

How we work with you.

The standard every person and agent at Lehvel works to.

  1. We watch your leads. On the client sites we run, we track each inquiry from the form to the owner’s inbox. If one may not have arrived, we send it again from team@lehvel.com and tell the owner.

  2. One address. Mail from Lehvel comes from team@lehvel.com, and replies come back to our desk. The one exception is a lead we forward to you: replying to it reaches your customer directly.

    In production

  3. A day, not “soon”. When we promise something, we give the day. If it moves, you hear it from us before it passes.

  4. Done means checked. We call a change live only after we have opened it on the live site ourselves.

  5. When we get it wrong. We tell you what happened in one sentence, fix it, and change how we work so it doesn’t happen the same way again.

  6. Your customers stay yours. We never contact your customers on our own, and we don’t name you publicly without your permission.

What we ask for, and what we do with it.

  1. For a Discovery. Your business name, primary website, a contact, what you want answered, and any materials you choose to share. Payment goes through Stripe. We never store card numbers.

  2. Access to your systems. We start from public material and what you share. If more access would help, we ask for it explicitly and only for the agreed scope. We don't ask for a master password.

  3. Google accounts. If you connect Google, we read only the sites and locations you select. You can revoke access from your Google account at any time.

  4. Selling and lists. We don't sell your information, and we don't add you to marketing lists without your consent.

  5. A copy, a correction or deletion. Ask for a copy of what we hold about your business, a correction, or deletion. We reply within 30 days.

  6. Keys and passwords. They stay out of our code. An automated scan looks for them before anything ships.

  7. If we built your website. Your agreement governs. Once the build fee is paid, you own the site's content, design and code, and your domain stays yours.

  8. Other companies’ services. We use models and services from OpenAI, Anthropic, Google, Perplexity, Vercel, Supabase and GitHub, under their terms. Using one isn't a partnership or an endorsement.

What we won’t do.

  1. Present planned work as running.

  2. Invent metrics, ratings, testimonials or AI scores.

  3. Claim certifications. We hold none.

  4. Call a passing test a verified change.

  5. Promise a ranking, or what an AI assistant will say.
