Jean is a free bioinformatics and biotech suite for the whole experiment. Design constructs, primers and CRISPR guides; simulate digests, PCR, Gibson and Golden Gate builds; analyze Sanger traces, qPCR and ddPCR runs, variants, trees, mass-spec proteomics and molecules; verify the clone you got. Every engine is checked against its field's reference tools and every result explains its method. It runs in the browser with no account, and as a remote MCP server any AI assistant can call.
