the loop

          
Your agent is not a PDF library.

          
Ask Claude, Codex, Cursor, or Grok for a report and they do not reach for a compiler. They write a “small” Python script, miss a dependency, retry, and bill you for the whole show. That is not a feature. That is a tax.

What happens

            
Writes Python. Installs the universe. Debugs A4.

            
Writes Markdown. One call. File exists.

          

          

            
Time

            
Thirty seconds to several minutes.

            
Milliseconds to convert. Seconds for the whole turn.

          

          

            
Where it runs

            
A notebook, a cloud converter, “please upload.”

            
Your disk. This site never sees the file.

          

          

            
Deps

            
Python, pip, Chrome, fonts, luck.

            
One static binary. docgen init-ai wires the agents.

          

        

        
Numbers are typical, not a contract. Fine print.

      

    


    

      

        
the compiler

        
Markdown to PDF. Markdown to Word. JSON to Excel.

        
A free local document converter for the command line. No upload, no Python, no Chrome. One static binary on your PATH — or an MCP tool the agent can call instead of writing reportlab.

        

          

            
pdf

            
Markdown to PDF

            
Skip WeasyPrint, reportlab, and headless Chrome. Write the report in Markdown; the compiler writes a themed PDF on disk.

            
docgen convert report.md -o report.pdf --theme modern-executive

            Markdown → PDF guide
          

          

            
word

            
Markdown to Word

            
Headings, lists, tables, and code become a real .docx. No Microsoft Word install required to generate the file.

            
docgen convert spec.md -o spec.docx --theme tech-spec

            Markdown → Word guide
          

          

            
excel

            
JSON / CSV to Excel

            
Dump an API response or a metrics CSV into a spreadsheet without standing up pandas and openpyxl.

            
docgen convert sales.json -o sales.xlsx

            JSON → Excel guide
          

        

      

    


    

      

        
field notes

        
Things we keep seeing.

        

          
“I’ll just write a small script.”It is never small.

          
Your $20 of fast requests should not die so a table can have the wrong page size.

          
No upload. This page is a poster. The compiler lives on your PATH.

        

      

    


    

      

        
one shot

        
Install it. Point the agent at it. Keep the money.

        
Works as docgen, doc, or docgen-cli. MCP for Claude Code, Codex, Cursor, Grok, OpenCode.
