Try the guided demo
The demo is self-guided inside the product, and the same sandbox also runs from your terminal. Either route shows the core Cassis loop: an agent hits a context gap, you teach it once, and that knowledge becomes governed context for every future question.
Start the tour
-
Create a free account. Cassis opens a seeded fictional marketplace project called Stallora.
-
Follow the tour in the product. It first asks a question the ontology cannot answer reliably, so you can see the missing context rather than a polished result.
-
Teach Cassis the missing definition in one line. The tour shows how that correction becomes a versioned metric, including the SQL behind it.
-
Ask the question again. This time Cassis uses the new context immediately. Then continue in the sandbox with your own questions.
That gap-to-fix loop is the product: context improves through use, while your data team keeps every change reviewable and governed.
Prefer the terminal?
The same sandbox runs headless. You ask over MCP, write the fix in a checkout, prove it with the CLI, and publish it by merging a pull request. Press Use this template on cassis-demo-stallora for your own repository, pre-wired with the sandbox’s ontology, MCP config, and CI. Its README is the walkthrough, about fifteen minutes.
