Optimize for AI & RAG

Extra cleanup for LLM ingestion: strip HTML, fix smart quotes, tidy Unicode and spacing.

Add YAML front matter

Prepend a metadata block (title, source, date, word & token counts) for knowledge bases and RAG.

Add table of contents

Build a linked index from the headings. Handy for long documents.

Export RAG chunks (.json)

Split the result into retrieval-ready chunks. Download per file from the result panel.

Most converters quietly upload your documents to a server. This one physically can't.

01Why

Source code,
ready to share.

Ruby leans on blocks, symbols, heredocs and string interpolation that break when pasted into plain prose. Converting drops the whole .rb file into a fenced block tagged ruby so it reads the same everywhere it lands.

RBapp.rb

def greet(name)

"Hello, #{name}"

end

puts greet("world")

MDapp.md

```ruby

def greet(name)

"Hello, #{name}"

end

puts greet("world")

```

02Features

Everything you
actually need.

Ruby source in, a clean tagged fenced block out, with no server and no account anywhere.

It never leaves your browser

Your .rb file is read on your own device. Nothing is uploaded to any server, ever.

local
RBapp.rb

# Heading

- point one

3 chunks

AI & RAG ready

Optional cleanup, YAML front matter, a table of contents and RAG chunk export.

Works offline

Once the page has loaded you can switch off your connection and it keeps converting.

```ruby

puts "hi"

```

Code, preserved

Each line lands verbatim in a fenced block tagged ruby, so blocks, symbols and interpolation read exactly as you wrote them.

éñü

Unicode safe

Accents, symbols and non-Latin scripts come through intact as UTF-8.

Free, and unlimited

No sign-up, no quotas, no watermarks. Convert one file or a thousand; it all runs the same way, on your own device.

03Fidelity

Every byte
survives.

Honest about what comes through, and what stays put. These are the same notes the Formats list shows for Ruby, so the page never drifts from what the converter really does.
