The Markdown Layer
for your AI.
Convert PDFs and Docs into clean, structured context directly inside ChatGPT, Claude, and Gemini. Get smarter responses with 40% fewer tokens.

What your AI actually sees
When you feed a PDF to an LLM, it doesn't see a document. It sees a stream of tokens polluted with layout artifacts, font metadata, and garbled characters. Markdown eliminates the noise.
