Curiosity and Elasticsearch
A toolkit, or a system
Curiosity ships as one system; Elasticsearch is a search engine to build on.

Who each tool is for
Different problems, honestly stated
Curiosity
For industrial and regulated teams whose knowledge sits in engineering systems and structured records, where the answer depends on how those records connect, and where the deployment has to run on their own infrastructure.
Elasticsearch
A flexible search engine with vector search and strong control over indexing, self-managed or in Elastic Cloud. It suits engineering teams that want to design and operate their own search layer. Elastic retired its packaged Workplace Search in version 9, so the search experience on Elastic is now something you build.
How Curiosity compares
Where the boundary falls
Elasticsearch is an excellent engine, and if your team wants to own the search layer it is a reasonable choice. Curiosity is the finished layer, including the connectors, permissions and graph you would otherwise build around it.
The parts you would build
Connectors, incremental sync, a typed graph, hybrid retrieval and an interface come with the system rather than being the next quarter of work.
Permissions at query time
Access is synced from the source systems and enforced on every query, down to the record. In a framework that is code your team writes and maintains.
Your code still fits
Custom endpoints, AI tools and agents are written against the graph in C# or Python, so you keep the control a framework gives you.
