Convert plain text to Markdown.
Drop a .txt file and get Markdown back with every line intact. It runs entirely in your browser, so your file never leaves your device.
Drag & drop your files

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.
Already text,
just renamed.
Plain text is already valid Markdown, so conversion keeps every line exactly as you wrote it. Give a tool a .md file and it treats the same words as structured, ready-to-use content.

Everything you
actually need.
Plain text in, Markdown out, with no server and no account anywhere.
It never leaves your browser
The .txt file is read and converted on your own device. Nothing is uploaded to any server, ever.
# 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.

Chat exports, tidied
A file detected as a chat export is reformatted into clean speaker-labeled lines.
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.
What survives
the trip.
Plain text is lossless: every character comes through. The right column is not lost work, it is simply formatting that plain text never held in the first place.
Kept
