You can run the whole flow without an account, but to keep a blueprint, you'll want to save it.
Save it
Signed in, you can save a blueprint to your account and find it again later under your agents. Anonymous runs aren't saved. We only record anonymous, lumped-together usage stats to help improve the product.
Download it
Any blueprint can be downloaded as Markdown: the whole thing, including the customer groups and their profiles, the things to check and the tests we suggest for each, who's circling, and what's buildable now. Drop it into a doc, a notebook, or hand it to a developer.
Saving is also how you'll be able to pick things back up over time as Discover Agents grows.
