No account, no API keys. You get your own private copy of a real corpus — documents, ingested chunks, a labelled question bank carrying its published scores, and a bank of pre-computed answers — and everything on top of it is live.
What works: asking questions and watching the semantic cache answer them, browsing retrieval and its scores, the eval bank and its published metrics, cost and savings accounting, and the config tabs — plus a scoped set of eval questions you can re-score and autotune for real, and watch the numbers move.
What doesn't: anything whose cost nothing bounds — uploading documents, re-chunking, generating new questions, replaying the corpus under other models. Those need your own keys.
The workspace is deleted after 2 hours. Nothing you do in it touches anyone else's.
