Inside another tool
These features have no page of their own because you use them in the middle of another job. Here are the direct links, so nobody has to guess where they were.
- OCR for scanned PDFsA scanned PDF is a photo: there is no text to copy. OCR reads it on your device, with the model downloaded once, and from there everything else works.Opens in PDF to Markdown
- Anonymize personal dataIDs, tax numbers, names, emails, phones and addresses become consistent placeholders: the same value always becomes the same placeholder, so the document still makes sense.Opens in PDF to Markdown
- Restore the real dataThe way back: paste the AI's answer and the placeholders turn into the real names and numbers again. Nothing is destroyed along the way.Opens in PDF to Markdown
- Chunk for AIA long document does not fit in a model's context. It is split at headings into pieces of the size you ask for, and each piece carries its heading so the thread is not lost.Opens in PDF to Markdown
Outside the browser
The same engine, for when the work is not a person with a mouse: an AI assistant on your machine, or a script.
- MCP serverTen tools for Claude Desktop, Claude Code or Cursor. The assistant reads and transforms your PDFs on your own machine, with no file going to any cloud.
npx -y @sirdaspdf/mcp - Command lineThe same engine in your terminal, with --json everywhere and stable exit codes. For scripts, batches and CI.
npx sirdas markdown informe.pdf - @sirdaspdf/core libraryThe bare engine, for Node or the browser, if you are building your own thing and want the parser and the anonymizer in your process.
