Navigate codebases by semantic concept rather than file path. An IDE for the meaning beneath the code.
Most code navigation tools answer the question "where is this thing?" Lexicon answers "what are all the things that mean this?" It constructs a semantic graph of your codebase — not a call graph or an import graph, but a concept graph.
Built on top of the Language Server Protocol and a fine-tuned embedding model, Lexicon lets you search by intent. "Show me all the places where we handle payment failures" returns not just string matches but semantic matches — code that does that thing, regardless of what it is named.
Each function and class is embedded as a vector using a model trained on code-comment pairs. These vectors are indexed and queried at development time. The result is a new kind of navigation: semantic, intent-aware, .
