plasmate vs chiasmus

plasmate: Plasmate compiles HTML into a Semantic Object Model (SOM), a structured representation that LLMs can reason about directly. It runs JavaScript via V8, supports Puppeteer via CDP, and produces output that is 10-800x smaller than raw HTML. It is purpose-built for AI agent pipelines, with MCP, Vercel AI SDK integrations, and over 60 ecosystem integrations.; chiasmus: Chiasmus is an MCP server that integrates formal verification (Z3, Prolog) and code analysis (tree-sitter) to solve complex logical and structural problems. It translates natural language into formal logic using templates and provides verified results. It also analyzes source code call graphs for dead code, impact, and reachability.
