Geostru AI
Browser-based platform of AI-assisted engineering applications for geotechnics, structures, hydraulics, geology, rock mechanics and surveying. Calculations run exclusively on GeoStru's own algorithms; the AI only assists with input, configuration and interpretation.
What is Geostru AI?
Geostru AI is a platform of browser-based engineering and geoscience applications published at geostru.ai, with the applications themselves running on nx.geostru.ai. It is operated by ENGSOFT SRL, a Romanian company in Cluj-Napoca which since August 2015 has handled the web services, e-commerce and software development of the GeoStru brand — an Italian engineering software house that traces its origins to the early 2000s.
The organising idea is a division of labour between the AI and the mathematics. All calculations are performed exclusively by GeoStru's algorithms; the artificial intelligence assists with analysis, configuration and interpretation but does not generate autonomous or unverifiable solutions. The publisher pushes this further than most: the calculation kernel is ported verbatim from the desktop products, keeping single-precision arithmetic where the original used it, so that results reproduce the desktop rather than drift from it.
Around twenty applications, all carrying the NX suffix, cover infrastructure and structural work (RPD for road pavements), geotechnics and geology (Loadcap for bearing capacity, Slope for slope stability, Liquiter for liquefaction, MRE for reinforced soil, SRS for soil nailing, GDW for gabion walls, RSL III and PS Advanced for seismic response), rock mechanics (GMS, Rock Mechanics, RockPlane), hydrogeology and hydraulics (HID, Hydrogeo, Runoff Lab), in-situ testing (Dynamic Probing), topography (Maps, Trispace) and geology (GeoSection, Stratigrapher). GeoDropbox adds a cloud GIS archive where projects are pinned on a map and searched with AI. Referenced standards include NTC 2018 and Circolare 2019, Eurocode 7 and 8, AASHTO LRFD and 1993, ICMS 2018, ISRM, DIN 4023 and CNR 146/92.
Access is entirely browser-based — no installation, no hardware key — with the interface in six languages, and the calculation methods are also exposed to AI clients through MCP servers. Commercially, a single prepaid credit wallet is spent across every application. Each session generates a unique audit ID allowing a full reconstruction of inputs, outputs and computation steps, which is the platform's answer to a designer's obligation to assess the reliability of the code used.
What it does
- Run geotechnical, structural, hydraulic and rock-mechanics checks in the browser against NTC 2018, Eurocode 7/8 or AASHTO LRFD partial factors
- Describe an engineering problem in plain language and let the assistant configure the analysis
- Generate a native calculation report in DOCX, PDF or DOC, with a session audit ID that reconstructs every step
- Import a geological report in PDF and turn it into a working model, or read items and text out of documents by OCR
- Build terrain from LAS or LAZ drone point clouds, then derive sections, contour maps, cut-and-fill volumes and elevation grids
- Export results to DXF, NEZ (UTM), CSV, GMT, SVG and PDF for use in other engineering software
- Call the certified calculation methods from an MCP client or through an API integration
When to use Geostru AI / When not to
A quick filter to help you decide if Geostru AI is the right fit.
When to use Geostru AI
- Geotechnical engineers who need code-compliant checks (NTC 2018, Eurocode 7/8, AASHTO LRFD) with an exportable calculation report
- Civil and structural design offices wanting traceable results, with a per-session audit ID that reconstructs every input and computation step
- Occasional users who prefer prepaid credits to a subscription: nothing renews automatically, and one wallet covers all twenty-plus applications
- Engineering geologists and hydrologists handling boreholes, stratigraphic logs, liquefaction, rainfall curves and stormwater attenuation sizing
- Surveyors and GIS practitioners working from drone point clouds, digital terrain models, section profiles and DXF or CSV exports
When not to use Geostru AI
- Anyone looking for a free option: there is no free tier and no trial, and an account only exists once a purchase has been completed
- Buyers who require third-party security or product certification: the publisher itself states that no certifying body is involved
- Teams needing a contractual availability guarantee, which the terms withhold unless a separate service level agreement has been signed
- Users of the historical GeoStru desktop range, which is licensed separately and sits outside the scope of these terms
- Occasional buyers who cannot spend their balance within twelve months, since credits expire on that horizon and are never refunded
How to use Geostru AI
A typical end-to-end flow, from setup to results.
- Choose a credit pack on the pricing page and complete the purchase — the account is created at that point, not before
- Sign in at geostru.ai; opening an application at nx.geostru.ai redirects to login, or back to pricing if the wallet is empty
- Pick the NX application matching your problem, or let the assistant suggest one from a plain-language description
- Describe the engineering problem in natural language so the assistant can help configure the analysis
- Build the model: draw the geometry, set stratigraphic contacts and materials, or import a PDF geological report or a DXF profile
- Select the regulatory framework and its partial factors — NTC 2018, Eurocode 7/8, AASHTO LRFD or user-defined coefficients
- Run the calculation; chargeable operations draw credits from the shared wallet at the rate published in the tariff
- Review the 2D section, the navigable 3D model and the stress diagrams, adjusting inputs as the drawing redraws live
- Verify the results yourself — the standard places the reliability assessment on the designer, and the validation documents supply the benchmarks
- Export the calculation report and the drawings, and monitor your balance, expiry date and consumption history in the account
Pros & Cons
Pros
- The calculation kernel is ported verbatim from the long-established desktop products rather than rewritten, so results reproduce a code base engineers already know
- Unusually candid validation posture: the publisher refuses the word certification for lack of a third-party body, and publishes benchmark cases, bibliography and the honest status of documents still in preparation
- Traceability is designed in — each session produces an audit ID and a full reconstruction of inputs, outputs and steps can be requested at any time
- One prepaid credit wallet works across the whole suite, with no subscription and no automatic renewal, and volume discounts reach 32 percent per credit
- Data protection is documented rather than asserted: EU and Switzerland hosting, named sub-processors, a DPA on request, and an unconditional commitment that content is not used to train AI models
- Nothing to install and no hardware key, with the interface available in six languages
- Validation documents state where a result diverges from its reference and explain why, instead of publishing a table of zeros
Cons
- No free tier and no trial: an account only comes into existence once a purchase has been completed
- Credits expire twelve months after top-up, are never refunded, and cannot be transferred or converted back into money
- Roughly half the validation documents are still listed as in preparation, including MRE, HID, RockPlane, GDW, PS Advanced, Dynamic Probing, Rock Mechanics, SRS, GMS, Hydrogeo and RPD
- No public API documentation: the footer entries pointing to documentation are inert, so integration goes through the vendor's team
- No security certification is claimed or published, and no availability guarantee applies without a separately signed service level agreement
- Unedited template residue is still live on the site — two About-page testimonials belong to a fictitious brand, a FAQ phone link carries a placeholder number, and the privacy policy still shows an editorial instruction
- Product pages under the English path are served in Italian, and GeoDropbox storage is billed on top of the credits
Pricing & Plans
There is no free plan and no free trial. Access is sold as prepaid credit packs, in euro and exclusive of VAT, spent from a single wallet valid across every GeoStru NX application. The lowest entry point is the Starter pack at 49 EUR for 500 credits (0.098 EUR per credit); the unit price falls as volume rises, down to 0.067 EUR per credit on the largest pack. Credits carry no subscription and no automatic renewal, but they expire twelve months after top-up and purchases are not refunded, whether the credits are unused, partly used or expired. GeoDropbox cloud storage is billed separately, as a monthly subscription starting at 12 EUR per month; it buys storage only and opens no calculation application, which is why it is not treated here as the entry price of the tool. The credit cost of each individual operation is published in the tariff on the pricing page and inside the applications, but is not visible without an account.

Data, GDPR & hosting
A consolidated view of how Geostru AI handles your data.
GDPR overview
Implementation is concrete and specific rather than declaratory. The privacy policy is drafted under Article 13 of Regulation (EU) 2016/679 and was last updated in July 2026. It names the controller — ENGSOFT SRL, fiscal code 30277934, trade register J2012001517126, Cluj-Napoca — and maps each purpose to a legal basis: contract (6.1.b), legal obligation (6.1.c), legitimate interest (6.1.f) and consent for marketing (6.1.a). Articles 15 to 22 rights are exercised at privacy@geostru.ai, an Article 28 data processing agreement is offered on request, and Article 32 measures are itemised (TLS encryption in transit, dedicated authentication, per-customer data isolation, access controls, security monitoring). The Romanian ANSPDCP is named as lead supervisory authority. Notably, the site never claims to be GDPR compliant in so many words — it simply applies the regulation.
Who owns the data?
Under the terms of use, you keep ownership of the projects, files and data you upload, and the outputs you generate — calculation reports, drawings, exported files — may be used freely in your professional work. EngSoft receives only the rights strictly necessary to host and process your content in order to deliver the service, including through the sub-processors named in the privacy policy. The roles are split explicitly: for account and usage data EngSoft is the data controller, while for the content you upload — and any third-party personal data it contains — you are the controller and EngSoft acts as your processor under Article 28 GDPR, working solely on your instructions. A data processing agreement is made available on request.
Reuse rights
You may reuse everything the platform produces for you without asking permission: the terms state that generated calculation reports, drawings and exports are free to use in your professional work, and every application ships export functions (DOCX, PDF, DXF, CSV and others) precisely so that you keep your own copies. On the publisher's side, use of your content is deliberately narrow. Uploaded files are processed on your instructions only, to run the service. The AI features — item extraction, OCR and the assistants — pass through Google's Gemini API on a paid plan, under terms where content is not used to train artificial intelligence models. No automated decision-making or profiling within the meaning of Article 22 GDPR is carried out, and the privacy policy states that personal data is not sold to third parties. Derived artefacts such as extracted text, embeddings and assistant conversation history are deleted together with the source content.
Data retention & training
Hosting summary
Files and content uploaded to the platform are hosted on Google cloud infrastructure located in the European Union and in Switzerland, a country covered by a European Commission adequacy decision, and are encrypted in transit. Some AI processing, also carried out by Google, may take place outside the EU in the United States; those transfers are governed by the Standard Contractual Clauses approved by the European Commission. Security measures cited under Article 32 GDPR include HTTPS/TLS encryption in transit, dedicated authentication, per-customer data isolation, access controls and security monitoring. The two declared sub-processors are Google, for infrastructure and the Gemini API, and Stripe for payments; full card details are not stored by the publisher. The controller is established in Romania, which makes the Romanian ANSPDCP the lead supervisory authority. Note that the marketing site itself resolves to a Google Compute Engine address in Poland, which describes the showcase server and not the jurisdiction of customer data.
Things to keep in mind
Risks and trade-offs to weigh before adopting Geostru AI.
- Automation bias is the central risk: the standard and the terms both place the assessment of the code's reliability, the choice of method and the verification of results on the designer who signs the report, not on the vendor
- The AI features — assistants, OCR, extraction from documents and drawings — are described by the publisher as producing approximate results that must always be checked before being used in a project
- Plain-language input can hide modelling assumptions: a description accepted by the assistant still resolves to a specific method and parameter set that the engineer remains responsible for auditing
- Fluent output can erode the habit of cross-checking; the platform offers several calculation methods on the same model precisely so that a single result is not taken at face value
- Continuity risk: applications can be added, changed or permanently withdrawn, and credits expire twelve months after top-up with no refund, so budget and project timing need to line up
- You upload third-party personal data at your own risk — for that content you are the controller and the publisher only the processor, so client data in project files is your compliance responsibility
- Marketing language and the compliance pages disagree on certification, and unedited template content is still live on the site, so any factual claim taken from the showcase should be verified against the terms, the privacy policy or the validation page
Setup & Integrations
Technical difficulty
Very low for the applications themselves. There is nothing to install, nothing to configure and no hardware key: buying a credit pack creates the account, and the applications open in any browser on any device. The assistant accepts a plain-language description, which lowers the barrier further on data entry. The real prerequisite is professional rather than technical — you need to be a qualified engineer able to choose the calculation method and verify the output. Integration work is a different matter: MCP and API access is arranged through the vendor's team, and no public developer documentation is published.

Should you pick Geostru AI?
Geostru AI is an unusually honest piece of engineering software marketing wrapped around a genuinely conservative technical proposition. Rather than claim that artificial intelligence computes better, the publisher confines it to input, configuration and interpretation, and carries the calculation kernel over from its desktop range unchanged — down to preserving single-precision arithmetic so that results match what engineers already trust. The validation section makes the same choice: it states plainly that this is validation, not certification, because no third-party body certifies the code, and it lists the documents still in preparation instead of hiding them.
That candour is the strongest reason to take the platform seriously, and it is reinforced by the per-session audit ID, the published benchmark cases and a data protection posture that is specific where most sites are vague: EU and Swiss hosting, named sub-processors, a DPA on request and an unconditional commitment not to train models on customer content.
The reservations are commercial and editorial rather than technical. There is no free tier and no trial, so evaluation costs at least 49 EUR, and credits expire after twelve months with no refund — a poor fit for genuinely occasional use. Roughly half the validation documents remain unwritten. There is no public API documentation despite MCP servers being advertised. And the showcase still carries unedited template residue — testimonials belonging to a fictitious brand, a placeholder phone link, an editorial instruction left in the privacy policy — alongside an unsourced 4.9 rating and product pages served in Italian under the English path.
The result is a young platform, on a domain registered in 2025, built on three decades of engineering work. Practitioners who already know GeoStru will find the transition low-risk; newcomers should budget the entry pack as the cost of finding out.
