Questions, bug reports, privacy concerns, or feedback about the offline-first PDF redaction tool. Reach out here.
Founder note
hddn is built for people who need to clean up PDFs before sending them to another person, service, or AI tool.
The goal is a practical privacy tool: load the redaction workspace, disconnect if you want, review every mark, and export a redacted copy without uploading the document to an app server.
