jb-markit

Use markit to convert almost anything into markdown.

Tested and adjusted against markit 0.5.0.

Install

bun add -g markit-ai

Best modes for agents

• markit <source> -q → raw markdown only
• markit <source> --json → structured output for parsing
• markit <source> -o output.md → write markdown to a file
• markit <source> -i extracted-images/ → save extracted images to a directory
• cat file.pdf | markit - → read from stdin

Quick start

# Documents
markit report.pdf
markit document.docx
markit slides.pptx
markit data.xlsx
markit proposal.pages
markit deck.key
markit budget.numbers

# Web
markit https://example.com/article
markit https://en.wikipedia.org/wiki/Markdown
markit https://github.com/user/repo
markit https://gist.github.com/user/abcdef

# Data / config
markit data.csv
markit config.json
markit schema.yaml

# Raw markdown or JSON
markit report.pdf -q
markit report.pdf --json

# Save output
markit report.pdf -o report.md

Media + AI

Images and audio include metadata extraction by default. AI descriptions/transcriptions require an API key.

# OpenAI (default)
export OPENAI_API_KEY=sk-...
markit photo.jpg
markit recording.mp3

# Anthropic
markit config set llm.provider anthropic
export ANTHROPIC_API_KEY=sk-ant-...
markit photo.jpg

# Focus image description / extraction
markit receipt.jpg -p "List all line items with prices as a table"
markit whiteboard.jpg -p "Extract all text verbatim"
markit diagram.png -p "Describe the architecture and data flow"

# Save extracted images alongside markdown output
markit report.pdf -i ./report-images -o report.md

Onboarding

Plugins

markit plugin install npm:markit-plugin-dwg
markit plugin install git:github.com/user/markit-plugin-ocr
markit plugin install ./my-plugin.ts
markit plugin list
markit plugin remove dwg

Plugin converters run before built-ins, so plugins can add new formats or override existing converters.

Good defaults

• Prefer -q when you want clean markdown in pipelines.
• Prefer --json when another tool or agent will parse the result.
• Use -p to constrain image description/extraction to the exact task.
• Use -i when you want extracted images written to a durable folder.
• Use -o when the conversion should become a durable artifact in the repo.
