Dedal IA
Belgian AI platform that runs construction sites for architects, safety coordinators and engineering practices. It drafts site reports and meeting minutes, produces CCTB 2022 quantity take-offs and issues Peppol-compliant invoices, all hosted in the EU.
What is Dedal IA?
Dedal IA is a software-as-a-service platform for running building sites, published in Belgium by LTC Group SRL. It addresses three audiences through dedicated pages: architects, health-and-safety coordinators, and engineering practices. Its argument is narrow and deliberate — rather than compete on generic project management, it builds everything around Belgian construction rules. The core of the product is document production. Site reports are dictated on site, with geotagged photos, and the AI structures them into the expected Belgian format: attendees, progress by lot, decisions, actions. Meeting minutes are generated from the recording, reviewed, then sent in one click. Electronic signature by email OTP, with a timestamped certificate, closes the loop. The take-off module is the flagship. The AI reads drawings and the specification, identifies the works, computes quantities and codes each line against CCTB 2022, the standard nomenclature published by the Walloon public service. The vendor documents six anti-hallucination guardrails — mandatory reference to the catalogue, unit validation, quantity traceability, controlled vocabulary, human sign-off and explicit flagging of uncertain estimates — plus versioning that keeps the history of every adjustment. A paid Scan 3D add-on extends this with iPhone LiDAR capture producing a 3D model, a 2D plan and a take-off. For safety coordinators the platform covers a whole assignment under the Royal Decree of 25 January 2001: a phase-structured safety and health plan, a timestamped coordination log, mobile site visits, coordination notices with proof of receipt, a continuously consolidated DIU, and the five-year archiving required by article 50. On the financial side it produces quotes from the take-off, issues Peppol BIS 3.0 invoices, applies the 6, 12 and 21 percent Belgian construction VAT rates including reverse charge, reconciles payments through a PSD2 bank connection and fires reminders on a configurable schedule. Around these sit a document store with AI question-answering, automated mailing, a multi-site Gantt planner, punch lists, permit tracking, a project map and a read-only client portal. The stack is published openly: React and Vite on the front, PostgreSQL through Supabase in Frankfurt, Stripe, Resend, Mapbox, OpenAI and Vercel behind it. Both the company and the product are very young, and the vendor says so itself.
What it does
- Turn dictated site observations and photos into a structured site report
- Generate the minutes of a site meeting from the recording, then validate and send them
- Produce a CCTB 2022 quantity take-off from PDF or DWG drawings and the specification
- Run a full safety-coordination assignment: PSS, coordination log, site visits, notices, DIU
- Issue quotes and Peppol BIS 3.0 invoices with the correct Belgian VAT rate
- Scan a room with an iPhone LiDAR capture and turn it into a 3D model, a 2D plan and a take-off
- Track payments through a PSD2 bank connection and chase unpaid invoices automatically
When to use Dedal IA / When not to
A quick filter to help you decide if Dedal IA is the right fit.
When to use Dedal IA
- Independent Belgian architects juggling one to three live sites who lose their evenings to reports, minutes and take-offs
- Architecture practices of five to fifteen people, since the licence is billed per office with unlimited users and unlimited sites
- Health-and-safety coordinators (level A and level B) who must produce a PSS, a coordination log, site-visit records and a DIU under the Belgian Royal Decree of 25 January 2001
- Engineering consultancies and general contractors working on Belgian sites who need CCTB-coded quantities that contractors will accept
- Practices still running their site paperwork on Word, Excel and paper binders, and ready to move the whole chain into one tool
When not to use Dedal IA
- Anyone looking for 3D BIM modelling — the vendor states plainly that it does none, and suggests pairing the tool with Archicad or Revit
- Practices working outside Belgium, since the value rests on CCTB 2022, Belgian construction VAT and the 2001 Royal Decree rather than on generic site management
- Teams that need an interface or support in a language other than French
- Organisations above twenty active users, who are routed to an Enterprise quote whose price is not published
- Large contractors running dozens of complex sites — the vendor itself points them towards Procore or Autodesk Construction Cloud
How to use Dedal IA
A typical end-to-end flow, from setup to results.
- Create an account at /register — no bank card is asked for, and the fourteen-day trial opens the full Max feature set immediately
- Sign in with an email and password or with Google, and switch on TOTP two-factor authentication if wanted
- Import a first site, which the vendor says takes about five minutes, and upload the PDF drawings
- On site, dictate observations and take geotagged photos from a phone; the AI structures them into a report
- Record a site meeting and let the platform draft the minutes, then review and send them to the attendees
- For a take-off, upload the drawings or the specification and let the AI detect the works and compute quantities
- Review the generated take-off line by line, adjust anything flagged as uncertain, then export it to XLSX or PDF
- Turn the take-off into a quote, convert the accepted quote into an invoice, and let the correct Belgian VAT rate apply
- Connect the bank account through PSD2 so payments reconcile themselves, and set the reminder schedule
- At day fourteen, either add a payment method from Settings to activate Pro or Max, or let the account fall back to read-only with the data still exportable
Pros & Cons
Pros
- Regulatory depth that is genuinely rare: CCTB 2022, the Royal Decree of 25 January 2001, Peppol BIS 3.0, Belgian construction VAT and the Order of Architects mention are all handled natively
- One continuous chain from the scan to the take-off to the invoice, replacing several tools that do not talk to each other
- Priced per practice with unlimited users and unlimited sites, which removes the per-seat arithmetic that penalises growing teams
- A fourteen-day trial of the most complete plan, with no bank card and no commitment, so evaluation costs nothing
- Unusual candour about the AI: six guardrails are documented on the take-off and human validation is required before export
- Transparent hosting and processing — seven subprocessors named, Frankfurt hosting stated, DPA available on request, and a repeated commitment that customer data is not used to train models
- Real portability: full JSON export plus PDF, Excel and CSV at any time, with no minimum term and cancellation from the Stripe portal
Cons
- The published terms describe an offer that no longer exists: two formulas, a permanent free demonstration tier and a Pro plan at 79 EUR including VAT, with no mention of the Max plan the site actually sells excluding VAT — a 21 percent gap on the headline price
- Both the company and the domain are brand new, so there is no track record, no independent review and no archived history to check the vendor against
- Several advertised capabilities are announcements rather than deliveries: the mobile apps are promised for 2026, and the iPhone capture that the paid Scan 3D add-on depends on is still described as coming soon to the App Store
- The site contradicts itself on Peppol invoicing, calling it early access and coming soon on the homepage while the feature page states that invoices are already issued in that format
- APIs are offered to engineering practices but no public documentation exists anywhere on the site, so integration effort cannot be scoped before signing
- French only, with no dedicated support address — support is promised in French within 24 working hours but runs through a generic contact mailbox
- The time savings quoted, up to 80 percent on take-offs and up to five hours a month on invoicing, come from the vendor's own internal tests and are hedged as such
Pricing & Plans
No permanent free plan is offered in the published price list. The commercial grid sells two subscriptions and one add-on, and the cheapest paid entry point is the Pro plan at 79 EUR per month excluding VAT, or 790 EUR per year excluding VAT. The Max plan costs 249 EUR per month excluding VAT, or 2,490 EUR per year. The Scan 3D add-on is charged 14.90 EUR per month on top of a subscription and is not available on its own. Pricing is per practice rather than per seat, with unlimited users and unlimited sites included; above twenty active users the vendor asks prospects to request an Enterprise quote, whose amount is not published. A fourteen-day trial of the complete Max feature set is available without a bank card. Readers should note two things. The 0 EUR figure visible on the homepage is not a plan: it is the card authorisation amount taken during the trial, and only for exporting and sending. And the terms and conditions still describe a different structure — a permanent free demonstration mode and a Pro plan at 79 EUR including VAT — which should be clarified with the publisher before committing.

Data, GDPR & hosting
A consolidated view of how Dedal IA handles your data.
GDPR overview
GDPR compliance is claimed explicitly and backed by concrete detail. The privacy policy, last updated 20 April 2026, names LTC Group SRL as controller with its enterprise number, tabulates a legal basis for each purpose (contract, legal obligation, legitimate interest, consent for Google sign-in), lists seven named subprocessors and describes non-EU transfers as covered by Standard Contractual Clauses and the Data Privacy Framework. Data-subject rights are spelled out — access, rectification, portability through a JSON export, erasure, objection, restriction, withdrawal of consent — with a one-month response target and a pointer to the Belgian Data Protection Authority. A DPA is offered on request. As the publisher is established in Belgium, no Article 27 representative is required or named.
Who owns the data?
The customer keeps ownership. Article 8 of the terms states that the client retains full ownership of everything fed into the platform: projects, clients, reports, documents. The privacy policy repeats that business records entered by the user remain that user's exclusive property. What LTC Group keeps for itself is the software side — source code, graphics, software architecture and the Dedal IA brand. The publisher processes customer content only to run the service, and states across four separate pages that none of it is used to train AI models. Data can be pulled back out at any time: a full JSON export sits under Settings, and PDF, Excel and CSV exports are available throughout.
Reuse rights
Nothing in the terms restricts what customers do with their own content. Because the client keeps full ownership of the projects, reports, minutes, take-offs and invoices produced in the platform, those documents can be reused, sent to contractors and clients, archived or fed into another system without asking the publisher for permission — the terms in fact make the customer solely responsible for the accuracy and for keeping an external backup. Export routes are built in: a full JSON export of the account, plus per-document PDF, Excel and CSV output, and accounting exports in CODA, Peppol or CSV. The publisher's own reuse is limited to operating the service; it commits to not training AI models on customer data. Third-party processing happens only through the seven named subprocessors, and the OpenAI component is triggered only when the user opens the AI assistant.
Data retention & training
Hosting summary
Data stays in the European Union. The database, authentication and file storage run on Supabase in its Frankfurt region, and the legal notice describes the servers as Supabase and AWS in Frankfurt. The web application and the marketing site are served by Vercel in EU and EEA regions. Payments are handled by Stripe Payments Europe in Ireland. Traffic is encrypted with TLS 1.3, data at rest with AES-256, and daily backups are kept for seven days. Tenants are isolated through PostgreSQL row-level security, and documents live in private buckets reachable only through signed access. Three points deserve attention. The site names the city, Frankfurt, rather than the country. Several processors are US-incorporated companies operating EU regions — Supabase, Vercel, Google, OpenAI, Resend and Mapbox — so transfers outside the EU do occur; the publisher says they are covered by Standard Contractual Clauses and the Data Privacy Framework. And Vercel's EU and EEA regions are stated without naming a city.
Things to keep in mind
Risks and trade-offs to weigh before adopting Dedal IA.
- The terms and conditions and the price list describe different offers, including a 79 EUR figure quoted once excluding and once including VAT; get the applicable version confirmed in writing before subscribing
- AI-drafted reports, minutes and take-offs are professional deliverables that carry liability — the vendor requires human validation before export for a reason, and a reviewer who stops reading carefully is the real risk here
- SOC 2 Type II belongs to Supabase and PCI-DSS level 1 to Stripe; these are the hosting and payment providers' certifications, not the publisher's own, and should not be read as such
- The site advertises analytics cookies subject to consent in its legal notice and cookie banner while the privacy policy states that no third-party analytics tracker is used; the page also loads a PostHog endpoint that appears in neither published subprocessor list
- The CCTB is a Walloon standard: the site sells Belgian compliance without stating how far that extends in Flanders or Brussels, which is worth checking for practices working outside Wallonia
- Quoted productivity gains of up to 80 percent on take-offs and up to five hours a month on invoicing come from the publisher's internal tests, not from an external audit
- Concentrating reports, minutes, take-offs, invoices and legal archives in one young vendor creates real dependency; the JSON and CSV exports exist and should be used regularly rather than only on the way out
Setup & Integrations
Technical difficulty
Low on the technical side. It is a pure SaaS product with nothing to install: create an account, and the trial opens without a bank card. The publisher says a first site can be imported in about five minutes, offers help getting started and accepts PDF drawings directly. Two optional steps take a little more care — connecting a bank account through PSD2, and syncing the calendar with Outlook or Google Calendar. The real effort is professional rather than technical: configuring reminder schedules, fee scales and VAT rules, and above all reviewing every AI-generated take-off before it is sent out.

Should you pick Dedal IA?
Dedal IA is a narrow tool, and that is its strongest argument. Almost everything it does could be found elsewhere in some form; what cannot be found elsewhere is the combination of CCTB 2022 coding, safety coordination under the Royal Decree of 25 January 2001, Belgian construction VAT and Peppol invoicing in one place. For a Belgian architect or safety coordinator that verticality is the whole point, and the per-practice pricing with unlimited users makes it easier to justify across a small team than per-seat alternatives. The functional reach is wide for such a young publisher — reports, minutes, take-offs, quotes, invoices, planning, punch lists, permits, document management — and the posture around the AI is more candid than usual: six guardrails documented, human validation required before export, subprocessors named, and a repeated commitment that customer data is never used to train models. The counterweight is maturity. The company and the domain are both very recent, there is no independent track record to check, and several selling points are still announcements rather than shipped features: the mobile apps, and the iPhone capture that the paid Scan 3D add-on depends on. More awkwardly, the site contradicts itself in places. The terms and conditions still describe a two-tier offer with a permanent free demonstration mode and a Pro plan at 79 EUR including VAT, while the price list sells Pro and Max excluding VAT. Peppol invoicing is called coming soon on one page and already live on another. None of that is disqualifying, and the fourteen-day trial without a card makes evaluation free. But the contractual terms and the exact scope of what ships today are worth settling in writing with the publisher before signing anything.
