Built around how rail engineers actually work

Not just search — a co-pilot for the compliance tasks that slow your project down most.

Sanity-check your designs
Paste a design assumption or parameter into the query box — get back the exact TSI or ERA clause it must satisfy, with a plain-English verdict on whether your value is within scope.
Check reports for compliance gaps
Paste a section of a technical report — the system identifies which clauses it covers and which requirements are missing or contradicted, with citations back to the source standard.
Answer RFI questions in minutes
When a client or NoBo raises a question referencing a specific clause, look it up instantly — no manual PDF trawl. Get the clause text, context, and related requirements in one response.
Stay ahead of standard updates
ERA and TSI standards are revised on rolling cycles. Get alerted when documents in your corpus are updated, and ask "what changed in version X vs Y" to find the delta that affects your project.

Run it on your own infrastructure

The cloud version contains 57 public standards. Docker gives you those plus your own purchased licensed standards (CENELEC/EN, UIC). Professional goes further: internal procedures, national rules, NoBo/DeBo assessment forms — every document type your organisation works with, queryable in one place.

Why Docker? Privacy and completeness. Nothing leaves your server — ideal for licensed standards (CENELEC/EN, UIC) or any sensitive documentation. Starter covers purchased licensed standards alongside the public corpus. Professional adds internal procedures, national rules, and NoBo/DeBo forms — every document type your organisation generates or relies on — plus report sanity check. Your infrastructure, your corpus, your control.

Frequently asked questions

Your account drops to the Free tier automatically — no charge, no interruption. You keep access to all 57+ standards at 20 queries per month. Upgrade whenever you need more.
Yes — the Docker edition supports bring-your-own API key for both Anthropic Claude and, in air-gapped mode, a locally hosted Ollama model. Cloud plans use shared API capacity included in your subscription.
All 57+ publicly available ERA, TSI, RATO, CENELEC and UIC documents are included in every plan. See the full list on the Standards Coverage page. Licensed standards (e.g. purchased CENELEC/EN norms) require the Docker edition.
One question submitted to the search interface equals one query. Follow-up questions in the same conversation each count as individual queries. Editing and re-submitting a question also counts as a new query.
Yes. Upgrades take effect immediately and billing is prorated — you only pay for the remaining days in your current period. Downgrades take effect at the end of your current billing cycle.
Check the Standards Coverage page for the full index. If a standard you need is licensed or proprietary (e.g. CENELEC, DIN, NR/SP), the Docker edition lets you upload your own copy so it becomes queryable alongside the public corpus.
Yes. Paste a paragraph or section from your technical report into the query box and ask "does this satisfy [TSI/ERA clause X]?" The system retrieves the relevant clauses, compares them to your text, and returns a cited assessment — highlighting anything that is missing or contradicts the requirement. The Docker Professional edition extends this by letting you check against your own uploaded documents too (e.g. internal engineering procedures or project-specific specs).
