flowcheck

Students study from text and flowcharts, and AI can make flowcharts in seconds. It can't show you which bullets it made up. flowcheck turns a reading into a branching flowchart and ties every bullet to a sentence from the source. Muse Spark 1.2 writes the chart. Then plain code, not a model, checks that each quoted sentence appears in the source text word for word, and checks the chart's structure. A chart with a dead end or an unlabeled loop fails. Anything still unconfirmed after one repair round turns red with a warning sign, so you know what to re-read. An optional second pass, --verify, uses a model to judge whether a quote really supports its claim. You can use it three ways: a command line, a web UI, or an agentic skill in Muse Code. All three share the same engine and the same checks. The output is plain Mermaid, so any renderer opens it. I tested it on Wikipedia articles and a MedMCQA exam question. It is exam practice and checks documents, not patients.
