AI assistants and search decision
Aviation.Bot
A competent technical user can reproduce the core Q&A, search, and citation features, but the full commercial product (live EUR-Lex sync, curated standards mapping, audit polish, and vendor support) is nontrivial to match and would require ongoing ops and integrations.

Not priced
No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Aviation.Bot alternatives, with the arithmetic →
What a replacement has to do
- User asks a regulation question → system finds exact regulation text and version → returns a cited answer with link/permalink → user optionally compares versions or saves the clause.
What it still won’t have
- Commercial EUR-Lex integration and its real-time 'see which rules changed today' functionality
- Industry-specific mappings (e.g., Standards Mapping to ICAO/EUROCAE/RTCA) curated by the vendor
- Audit-ready product polish, UIs for traceable permanent links, and vendor support/SLAs
What remains hard
- Product polish and ongoing maintenance
First-year cost
No published price
Aviation.Bot does not publish a price we could read, so there is nothing to compare against. What building costs is below.

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a web app (Node.js + Express backend, PostgreSQL, Elasticsearch or OpenSearch for full-text search, Python worker for PDF parsing and EUR-Lex sync, React frontend) that: 1) ingests EASA Easy Access Rules PDFs with version metadata and exposes them in Postgres; 2) implements a periodic EUR-Lex sync worker to fetch amendment notices and store diffs; 3) indexes full text and paragraph-level anchors in Elasticsearch and exposes a citation API that returns exact paragraph text and a stable permalink; 4) provides a chat UI that composes context-aware prompts and returns answers annotated with clickable citations from the citation API; 5) implements a compare/diff view highlighting changes between versions; 6) includes user collections/bookmarks and shareable links. Out of scope: enterprise billing, multi-tenant advanced access control, training proprietary LLMs. Include error handling for parsing and network failures and automated tests for the ingestion worker, citation API, and chat integration.

- 4 cited sources+3
- 3/3 assessment runs agreed+4
- Evidence score64
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
