About Plainmark
Conversion you can check, not just trust.
Plainmark turns text-based PDFs into editable Markdown while keeping the source document visible beside the result.
Why it exists
PDFs are useful for sharing finished documents, but awkward when the words need to move into notes, documentation, or another writing system. Plainmark provides a practical starting point without hiding the original page.
Review comes first
Document conversion is rarely perfect. Layouts, tables, image placement, and unusual typography can change during extraction. The side-by-side workspace makes those differences easier to notice and correct before export.
What it handles today
Plainmark works best with text-based reports, papers, and presentations. It preserves common elements such as headings, paragraphs, lists, and embedded images when possible. Scanned PDFs are not currently supported because Plainmark does not run OCR.
A focused tool
Plainmark does not require an account and does not send document contents to a third-party AI service. The goal is deliberately narrow: help people move readable PDF content into clean Markdown.
