Plasmate
The browser engine for AI agents.
We build tools that help AI agents understand and interact with the web. Our flagship project, Plasmate, transforms raw HTML into a Semantic Object Model (SOM) — structured, meaningful data that AI can actually work with.
Web pages are built for humans, not machines. AI agents waste tokens parsing noisy HTML, ads, and navigation. Plasmate solves this by extracting what matters: the semantic content.
- 16x fewer tokens than raw HTML
- Structured output ready for LLM consumption
- Framework integrations for Vercel AI, LangChain, and more
- MCP server for Claude Code, Cursor, and other AI tools
