Field notes
The hint control has several levels of disclosure: it can name a technique or highlight the candidates involved. The analyzer accepts a pasted puzzle and returns the techniques used, the hardest one required, and a difficulty rating. The site lists 32 technique guides with examples that can be stepped through in the app, and identifies the software as GPL-3.0-or-later.
