Who DIAVAG is built for

A platform for expert appraisers. Not for corporations.

View into the cockpit of a vehicle during an appraisal
Solo appraisers

You appraise. The platform does the writing.

You work on your own, often without an office behind you. DIAVAG takes the writing off your hands: you capture on site, review the draft and approve it. No digital experience required.

Small offices

One shared standard for every appraisal.

Two to ten appraisers, many jobs, different writing styles. With DIAVAG every appraisal follows the same process, with your letterhead and a traceable approval.

We modernise the delivery.

Every asset class comes with its own capture profile, from the battery test on an EV to operating hours and hydraulics on a construction machine. The workflow always stays the same: capture, review, deliver under your brand.

What's in it for you. Five answers

Your expertise makes the appraisal valuable. Your time shouldn't be the price.

AI chat in the DIAVAG customer portal: the customer asks about the battery value and the valuation, and the chat answers straight from the appraisal
From the customer portal: the AI chat answers only from the appraisal, and you see every question.

DIAVAG is built for expert appraisers who would rather assess than type. No digital experience needed: if you can record a voice note, you can work with DIAVAG.

Time.
The platform handles the wording, formatting and assembly. You review and approve instead of spending your evenings at the desk.
Calm.
Your customers' questions land in the portal instead of on your phone. The AI chat answers what the appraisal says. You see every question and step in only when needed.
Presence.
Email, PDF and portal carry your logo and run on your domain. Your one-person office comes across as professional as a large firm.
Control.
No appraisal leaves the system without your logged approval and signature. The AI suggests, you decide.
Data protection.
Your data is stored in the EU, GDPR-compliant, and is not used to train AI models. You remain the owner of your data.
How to measure us

No logos, no number games. Five principles.

Your readings, your devices: you run the diagnostics as before, and the platform takes over afterwards.

With appraisals, trust is not built on marketing promises but on traceability. That's why we don't show you purchased seals, but the rules the platform works by.

The human gives approval

Human-in-the-loop, in the spirit of VDI 5900: the AI creates drafts, but the expert appraiser is accountable for the appraisal. Nothing is delivered without your review and signature.

Every figure has a source

Every statement in the draft is tied to a data field you captured yourself. Anything not measured or noted does not appear in the text.

Hosting in the EU

Your assignments, photos and appraisals are stored on servers in the European Union and processed in a GDPR-compliant way.

No training use

Your appraisals and customer data are not used to train AI models. You remain the owner of your data.

Your brand, not ours

Your customer sees your logo, your colors and your domain. DIAVAG is the tool in the background, not the sender on the appraisal.

Questions and answers

What you should know before you start.

If your question isn’t covered here, write to us at info@diavag.com. We’ll answer you personally.

DIAVAG is a software platform for expert appraisers and assessors. You create an assignment, record measurements, photos and notes on site in plain language, and the platform turns them into an appraisal draft. You review the draft, approve it with your signature, and your client receives the appraisal as an email and PDF in your branding, including access to a client portal.
No. The AI creates a draft, based solely on the data you recorded yourself. Every statement is tied to a data field; there are no invented figures. You review the draft, change anything you don’t like, and approve it with your signature. No appraisal is delivered without your logged approval.
No. You work with your own measuring devices, just as before. For the platform, a smartphone for photos and notes on site and a computer or tablet for review and approval are all you need. You don’t need any special digital experience: on site you jot down or dictate in plain language instead of filling out forms.
You set up your logo, colors and domain once. After that, every appraisal PDF, delivery email and the client portal carry your identity. Delivery runs through your own domain, with DIAVAG staying in the background.
Your client receives an email with the appraisal as a PDF and access to the client portal. There they can view the appraisal and the photos and ask questions. The AI chat answers only from the content of the appraisal. You see every question asked, and via the follow-up button your client can reach you directly.
You can start for free and try the platform on real assignments. You’ll find the current terms on our pricing page at diavag.com/preise. If you have questions about your specific case, write to us at info@diavag.com or request a demo.
Your assignments, photos and appraisals are kept on servers in the European Union and processed in line with the GDPR. Your appraisals and client data are not used to train AI models. You remain the owner of your data.
For cars and electric vehicles as well as construction machinery and boats. Each asset class has its own capture profile; the process from capture to client portal is the same.
The next step

Try it with your next appraisal.

No migration project, no training days. You create an assignment, capture everything on site as usual, and see for yourself how little writing work is left.
