Commercial desktop app In development

Philter Desktop

Redact PII from documents on your own Windows machine. Philter Desktop opens PDF, Microsoft Word, and text files, finds the sensitive information with an AI model that runs entirely on your computer, and writes a redacted copy. Nothing is uploaded, and no service has to be running.

Philter Desktop is in active development and not yet released. Contact us about your use case and we will reach out as it nears release.

Every document is redacted on your computer, and nowhere else.

Philter Desktop opens, analyzes, and redacts each file locally on your own Windows machine. There is no cloud service, no server, and no network call at any step. Your documents, both the originals and the redacted copies, never leave the device, and it runs with no internet connection at all. We cannot see your files, because they are never sent anywhere.

  • 100% on-device: detection and redaction run on your machine
  • No uploads, no cloud, no servers, no network calls
  • Works fully offline, with no internet connection
  • Your documents never leave your computer

What Philter Desktop does

Runs on Windows

A native Windows application a non-technical user can install and run. No server to stand up, no command line, no cloud account.

Redacts PDF, Word, and text

Open a PDF, a Microsoft Word document (.docx), or a plain text file, and get a redacted copy back. The formats office and legal teams actually work in.

Configurable redaction policies

Choose what to redact and how, with the same policy engine that powers Philter. Start from a ready-made policy or tailor names, dates, account numbers, and your own custom terms.

Fully offline

Detection and redaction happen on your machine. Your documents never leave the computer, there are no outbound network calls, and it works with no internet connection at all.

AI-powered detection

The same trained Philterd model that powers the toolkit finds PII in context, not just with pattern matching, and runs in-process on your CPU.

Open source, auditable

The application is open source under the Apache license, the same as the rest of the Philterd toolkit. Your IT team can read exactly what it does and confirm it keeps your documents local.

Who Philter Desktop is for

Small law firms and solo practitioners

Redact court filings, discovery, and client documents on your own machine, with no IT department required.

Small practices handling sensitive records

Clinics, accountants, and advisors who need to scrub PII and PHI from documents without sending them to a cloud service.

Anyone who cannot stand up a server

When Philter (the self-hosted API) and Phileas (the embeddable library) are more than you need, Philter Desktop is the install-and-run option for a single Windows machine.

Not sure which Philterd tool fits? Contact us and we will help you choose. Philter Desktop is for a single Windows machine; Philter and Phileas are for pipelines and applications.

Built on the open source Philterd toolkit

Philter Desktop is the desktop face of Phileas, the open source redaction library underneath Philter. The application code is open and auditable, and inference runs locally with the Philterd PII model. For risk-sensitive work like legal and healthcare, that means a tool you can verify rather than trust on faith: the documents stay on the machine, and you can prove it.

Frequently asked questions

Is Philter Desktop available now?
Not yet. It is in active development. Contact us and we will reach out as it nears release.
Do my documents leave my computer?
No. Detection and redaction run entirely on your Windows machine, with no outbound network calls. It works with no internet connection. This is the point of a desktop tool for privileged and regulated documents.
Can you see my documents?
No, never, because your documents never leave your computer. Philter Desktop does all detection and redaction locally, so we have no way to see what you open or redact.
Is it open source?
Yes. The application is open source under the Apache license, like the rest of the Philterd toolkit, so you can audit exactly what it does. The $100 per user per year covers commercial use, the signed auto-updating build, a commercial license to the bundled PII model, and support. Personal and evaluation use is free.
What file types does it redact?
PDF, Microsoft Word documents (.docx), and plain text files at launch.
Can I control what gets redacted?
Yes. Philter Desktop uses the same configurable policy engine as Philter, so you decide which entity types to redact and how, and you can add your own terms and rules.

Philter Desktop brings the Philterd redaction toolkit to a single Windows machine, for small law firms, solo practitioners, and business users who need to redact sensitive documents without sending them to a cloud service. It is the offline, install-and-run companion to the self-hosted Philter API and the embeddable Phileas library.

Need offline redaction for your firm?

Whether you want to follow Philter Desktop as it nears release or scope a larger offline redaction deployment, you can work directly with the team that builds the toolkit. Contact us about what you are redacting and we will help.
