FAQ

Frequently asked questions

Everything you need to know about Smith.

Smith currently supports Word documents (.doc and .docx) and Markdown files (.md). We are actively working on adding support for additional formats including PDF, plain text, and more. Stay tuned for updates.
Smith uses advanced natural language processing to identify personally identifiable information (PII) such as names, email addresses, phone numbers, physical addresses, dates of birth, and more. Detected entities are highlighted for your review, and you can accept, reject, or add custom terms before the anonymization is applied.
Yes. Your documents are encrypted in transit and at rest. We do not share your documents with any third parties, and documents are only retained as long as you choose to store them. You can delete your documents at any time and they will be permanently removed from our systems.
Billing is usage-based. You are charged $0.01 each time you anonymize a document, and $0.20 per GB of storage used per month. There are no upfront costs or subscription fees. You are billed at the end of each billing cycle for the usage incurred during that period. Creating an account is completely free.
Absolutely. Once anonymized, you can download the document immediately in its original format. You can also keep it stored in Smith and organize it in folders for convenient access later. There is no limit to how many times you can download a stored document.
Folders let you organize your anonymized documents however you like — by project, client, date, or any other structure that fits your workflow. You can create as many folders as you need, move documents between folders, and rename or delete folders at any time. Folder organization is included at no extra cost.
