Open SEOOne login, one credit pack
Preview is free. A download spends one export credit on every tool. MD Clip charges for the saved Markdown, not for fetching the page. MD Diff charges only when the drafts differ. A second format, such as PowerPoint after PDF, is another credit. When 25 exports are used, buy another pack of 25 for $2.50. Credits do not expire.
Workflow
How it works
Bring a source, preview it free, then spend one export credit on the file you download.
Pick a tool
Converter, Publisher, Reverse, Slides, Clip, Diagram, or Diff. Each one is built for a single outcome.
Bring the source
Paste Markdown, upload a file, or clip a public page. Previewing needs no account.
Preview free
Check the document, social card, Markdown, deck, diagram, or draft comparison before you spend a credit.
Export once
Sign in and download. That file spends one export credit. A second format spends another. The first 3 are free, then 25 for $2.50, and you can buy that pack again.
Use cases
Built for every workflow
Each job maps to a tool. The account stays the same.
Technical writers
Keep the source in Markdown and hand stakeholders a styled DOCX or PDF. Diagrams in the file are rendered for the export.
MD ConverterBloggers and publishers
Turn a post into SEO front matter, JSON-LD, and a social card at 1200×630 before it goes live.
MD PublisherEditors with finished files
Bring HTML, Word, PDF, or plain text back to Markdown when the editable source is what you actually need.

Write the talk as headings and bullets, then download a PDF or PowerPoint deck.

Credits
What one export costs
Preview is free. The file you download spends one export credit. These are the same rules as checkout.
One download, one credit
HTML, DOCX, PDF, a social image, a clipped page, a slide deck, a diagram file, or a patch each spend one credit when you download that file.
A second file spends another
MD Slides charges once for PDF and again for PowerPoint. MD Diagram charges once for the .mmd file and again for the PNG. MD Publisher charges once for the Markdown and again for the social image. MD Converter batch charges one credit per file, and download-all returns a ZIP.
Two cases stay free
MD Clip does not charge for fetching a public page. It charges when you download the Markdown. MD Diff does not charge when the two drafts are identical.
When the pack is used up
Buy another pack of 25 exports for $2.50. There is no larger pack and no subscription. Credits do not expire, so a pack already on the account stays until those exports are used.

Security
What happens to your file
Temporary processing with automatic cleanup. Files you upload or export are processed on our server and later removed from a temporary folder. They are not kept as a document library.
Processed for conversion
MD Converter sends your Markdown to the server to build the preview and the export. Each tool sends only the file, page, or outline it needs.
Temporary files
An upload stays in a temporary folder until cleanup deletes it. On a long-running server that job runs every hour and deletes temporary files it finds. On this hosted site the hourly job does not run; files are deleted when a new server instance starts, so a file can remain until then. If a run fails, the file stays until a later run succeeds. The downloaded export is removed when the download finishes. This is not a fixed minute-by-minute promise.
One account for every export
Preview needs no account. Exporting from Converter, Publisher, Reverse, Slides, Clip, Diagram, or Diff uses the same login and the same credit count.
