About Plainmark
Plainmark is a focused PDF to Markdown product for one anonymous PDF at a time. It emphasizes reviewable document structure, portable output, and a short-lived server lifecycle.
What Plainmark is built to do
01
One focused workflow
Upload one text, scanned, or mixed PDF, review the recovered structure, then copy the Markdown or download a ZIP with local image assets.
02
Reviewable output
The product prioritizes headings, lists, tables, formulas, and image references that can continue into editing, AI context, and knowledge workflows.
03
Temporary by design
The first release has no account history. Server files enter cleanup after delivery, failure, cancellation, timeout, or expiry.
04
Honest limits
PDF layouts are not always recoverable without ambiguity. Complex tables, equations, reading order, and low-quality scans should be reviewed before reuse.
