Everything You Need to Know About Leide

Leide is an AI engineering platform built for offshore and maritime professionals. It combines four tools in one workspace:

AI Navigator — ask engineering design and compliance questions in plain language and get clause-cited answers in seconds.
Drawing Checker — upload a technical drawing and get an automated compliance review with findings classified by severity.
Engineering Calculators — pipe flow, bolt torque, weld sizing, pressure vessel, and padeye design — all with built-in AI assistance.
Project Management — organize drawings, assets, certificates, and queries into shared projects with your team.

Yes. Sign up and you get a 14-day free trial with full access to the AI Navigator, Drawing Checker, all five engineering calculators, and project management features. No credit card required.

During the trial you get a generous allowance of Navigator queries, drawing checks, and calculator runs. If you need more time to evaluate, reach out to hello@leide.ai.

Leide is designed for engineers and technical professionals working in offshore, maritime, and heavy industry — structural engineers, piping engineers, design engineers, QA/QC engineers, project engineers, and technical leads.

If you spend time looking up clauses, reviewing drawings for compliance, or running design calculations, Leide is built to accelerate those workflows.

Leide covers a wide range of offshore and structural engineering domains:

Structural design — steel structures, jackets, topsides, fatigue assessment
Lifting & rigging — padeye design, sling calculations, crane operations
Pressure vessels — ASME VIII and EN 13445 design, nozzle loads, MAWP
Piping — flow analysis, pipe sizing, stress analysis, material selection
Welding & fabrication — weld sizing, WPS guidance, NDT requirements
Materials — material certificates, corrosion, HISC, temperature limits
Drawing standards — tolerancing (GD&T), weld symbols, title blocks

Coverage spans DNV, NORSOK, ISO, EN, and ASME frameworks. New domains are added continuously based on user requests.

Type a question in plain language — for example, "What material certificate is required for padeye plates under DNV-ST-0378?"

The Navigator searches across its engineering knowledge base, retrieves the most relevant clauses, and returns an answer with specific references. Each answer includes source traceability so you can verify against the original document.

Typical response time is under 3 seconds.

In the Leide portal, go to the Knowledge Coverage page and use the request form to suggest an engineering domain or topic. Requests are reviewed and prioritised based on user demand.

You can also email hello@leide.ai with specific coverage requests.

The Navigator accelerates the lookup process — instead of searching through PDFs or paper copies, you get the relevant clause in seconds. Every answer includes references so you can go straight to the source for verification.

It does not replace engineering judgement. Final decisions always rest with the responsible engineer.

The AI performs a two-pass analysis. First, it extracts drawing data — dimensions, tolerances, weld symbols, notes, material callouts, NDT requirements, and title block information. Then it checks the extracted data against 15+ specific rules covering:

Material & certificates — correct certificate type (e.g. EN 10204), material traceability
Dimensional standards — tolerance callouts, general tolerance reference (ISO 2768)
Welding — weld symbol convention (ISO 2553 vs AWS A2.4), throat/leg size, NDT
Drawing presentation — title block completeness, scale, projection method
Design-specific — SWL marking, proof load, corrosion allowance (where applicable)

Each finding is classified as CRITICAL, MAJOR, or MINOR with a clause reference where available.

PDF, PNG, JPG, and JPEG files up to 32 MB. Multi-page PDFs are fully supported — the AI reads all pages, which is important for assembly drawings where the BOM appears on a separate sheet.

For best results, use exported PDFs from CAD software (AutoCAD, SolidWorks, Inventor) rather than scanned paper drawings. Scans work, but OCR quality affects extraction accuracy.

You can also upload multiple files in one session — an assembly drawing and its component drawings — and Leide will cross-check BOM completeness across the set.

Yes. All drawing check results are saved to your account. Open the Recent Analyses panel to see your history. Click any previous result to re-open the full findings report, including any notes you added.

For batch uploads, you can re-open the combined batch report from the history view — all findings across the batch are reconstructed with their original severity classifications and statuses.

Leide includes five engineering calculators, each with built-in AI assistance:

Flow Calculator — pipe sizing, pressure drop (Darcy-Weisbach), system curves, erosional velocity
Bolt Torque — VDI 2230 method, offshore materials (B7, L7, duplex), subsea tensioner mode
Weld Sizing — EN 1993-1-8 and AISC, fillet and butt welds, fabrication guidance, fatigue classification
Pressure Vessel — ASME VIII Division 1 and EN 13445-3 dual-code, shell/head/nozzle sizing, MAWP
Padeye Calculator — DNV-ST-0378 Appendix E, five utilisation ratio checks with clause references

All calculators produce clause-referenced results. The AI can explain results, suggest next steps, and flag potential issues.

Yes. The standalone padeye calculator is available without an account. It performs all five DNV-ST-0378 Appendix E utilisation checks — bearing, shear-out, combined stress, cheek plate weld, and net section.

The full portal version adds AI assistance, project linking, drawing pre-fill (results from drawing checks auto-populate calculator inputs), and history tracking.

Yes. Leide is hosted on Railway (EU region) with data stored in a persistent database. Drawings you upload are processed in memory and passed to the AI for analysis — the original file is not retained server-side after processing.

Authentication is handled by Clerk with session management and full user isolation. Each user can only access their own data and projects they have been explicitly invited to.

For enterprise deployments or custom data residency requirements, contact hello@leide.ai.

Yes. Open any project and invite colleagues by email. Shared project members can view all drawings, queries, assets, and calculations in the project — no separate sign-up flow needed for invitees.

Project owners control access: members can be removed at any time, and members can also leave a shared project themselves. Shared projects show a team badge in the sidebar.

Yes. The Asset Register lets you create assets within a project, attach certificates (with certificate number, applicable standard, expiry date, and next inspection date), and get automated alerts when certificates are approaching expiry.

Drawing check results can be linked to specific assets for full traceability — from drawing review to certificate status in one workspace.

No. Leide is a productivity tool that accelerates engineering workflows — finding clauses, checking drawings, running calculations. All outputs include source references so engineers can verify.

The Drawing Checker surfaces potential issues for engineer review — it does not make accept/reject decisions. Calculator results include the applicable code clauses and assumptions. Final engineering judgement always rests with the responsible engineer.
