The problem
The answer exists. Finding it is the job.
A single vehicle authorisation or safety-case question can touch a TSI, two or three EN 5012x parts, a UIC leaflet and a national rule — each a few hundred pages, each with its own numbering, each cross-referencing the others. So the work isn't understanding the requirement. It's locating it: the right clause, in the right revision, and every place it's mentioned again downstream.
Today that means keyword-searching PDFs, chasing "see clause 6.2.3", and rebuilding the same cross-reference map you built last month. It's slow, it's easy to miss a reference, and it's the least valuable part of an expert's day.
- Hours per week lost to searching, not assessing.
- Miss one cross-reference and it surfaces in review — or later.
- The knowledge lives in a handful of people's heads and a folder of PDFs.
How it works
Three steps from a question in your own language to a clause you can cite.
Pick your jurisdiction and start asking
The public corpus is already built in and indexed: TSIs, ERA/ERTMS subset documents, EU directives and national rules. On Pro, add your own licensed copies of copyrighted standards (EN 5012x, UIC leaflets) to your private, EU-hosted workspace. We don't redistribute standards — copyrighted texts are searchable only from copies you already hold a licence for.
Ask in your own language
"What are the SIL apportionment requirements for a trackside interlocking function?" "Vilka krav ställs på dörrkontroll i förarhytten?" Ask the way you'd ask a colleague, in English, German, French, Spanish, Italian, Dutch, Swedish, Norwegian or Finnish. Answers cite the clause in the official language version of the standard, so a Swedish question returns the Swedish text of the TSI, not a translation. No Boolean syntax, no guessing the exact wording the standard used.
Get the answer, with the citation
Every answer points to the exact section, table or figure number in your source document, so you can verify it and cite it. Open the passage in one click. And if a question needs a standard you haven't ingested, the free plan tells you exactly which standard is required and points you to the upload or upgrade path — rather than guessing. Trust, then verify — never the other way round.
Pricing
Start free on a real question. Upgrade when the time-saving pays for itself.
For trying it on a real question before you commit.
- 20 queries per month — enough to test it on this week's work
- Answers with section / table / figure citations
- Query the built-in public corpus — TSIs, ERA/ERTMS subsets, EU directives and national rules
- Honest gaps — if a question needs a standard you haven't ingested, it tells you which one, instead of guessing
For assessors and RAMS / compliance engineers who cross-reference standards daily.
- 100 queries per day
- Private document uploads — your licensed EN 5012x and UIC copies, searchable in your workspace
- Citations to exact clause / table / figure for every answer
