A LITTLE LESS MANUAL. A LOT MORE INTENTIONAL.

A reviewed copy.
In three deliberate steps.

Prepare a useful copy for the next task.
You decide what leaves your workspace.

01 / SELECT↗

Bring your documents.

Open your files, choose the relevant country and domain, and start a local review. Your original stays intact.

02 / REVIEW↗

Review the details.

Inspect grouped findings. Redact, use consistent placeholders or keep a value. Manually mark anything the detector missed.

03 / SAVE & CHECK↙

Save a separate copy.

Export a new document. Check the result and any unresolved content before sharing it with an AI service or another person.

THREE REASONS TO REDACT FIRST

Before you upload.
Before you share.

Remove sensitive details offline.
Then share only what the next task needs.

01 / UPLOADING TO AI

Get AI help with a document.

Need a summary, explanation or analysis? Redact names, contact details and account numbers before uploading a report, contract or statement to an AI tool. Keep the context it needs to help.

02 / SHARING WITH A THIRD PARTY

Share the work. Limit the personal details.

Sending a document to a consultant, vendor or external reviewer? Remove client, employee or customer information they do not need, then send a reviewed copy while keeping your original.

03 / USING ONLINE DOCUMENT TOOLS

Redact before an online upload.

Using a website to merge, compress or convert a document? Remove sensitive information on your computer first. Check the saved copy, then upload that version to the online service you choose.

You decide whether sharing is appropriate. Unusual facts, amounts and relationships can still identify someone after direct identifiers are removed.

MORE THAN A BLACK BOX OVER A NAME

Control over the details.
Room for your judgment.

A focused desktop workflow.
No automatic upload to an AI service.

Local recognition

Rules and a local language model help find structured identifiers and entities such as names and organizations. Document processing happens on your device.

Consistent replacements

Use recognizable placeholders such as PERSON_1 and ORG_1 to retain context. Review repeated occurrences together instead of treating every match in isolation.

Your review, your corrections

Choose an action for a finding, keep relevant text, or mark missed details. A detector’s suggestion is the start of a decision, not the last word.

Country and domain context

Combine common recognition with country-specific identifier coverage and domain choices. Select the scope that fits the document and its intended use.

A new copy, not an overwritten original

Keep the source document separate from your redacted output. Review the new copy before deciding where to send it.

Clear limits, visible review

Scans, protected files and complex embedded content need specific support. Check format coverage and unresolved regions rather than assuming an empty finding list means a clean file.

FIRST-RELEASE FORMAT FOCUS

Documents you already work with.

The initial scope is English-language documents. Exact tested coverage and system requirements will accompany each installer.

PDF

Text-based PDFs

Parseable, unencrypted documents. Scanned or mixed-image PDFs require a separately tested processing path.

DOCX

Word documents

Ordinary text, tables, headers and footers. Complex structures and embedded content need explicit support.

TXT

Plain text

UTF-8 documents and pasted text, with useful text and line structure preserved.

  3. Choose country and domain. Select India and Accounting & tax for this example.
  4. Set a default action. Choose consistent replacement tokens such as PERSON_1.
  5. Redact and review. Run local detection, check the findings and resolve anything that needs review.

  7. View the redacted files. Open the redacted view in the app and check the full copy before sharing.
A LOCAL TOOL. A DELIBERATE DECISION.

Redaction happens here.
Sharing stays up to you.

No document upload for processing. The desktop workflow processes the source locally. This website does not accept document uploads.

No automatic handoff to AI. You choose whether to share the reviewed copy and which service or person should receive it.

No promise of anonymity. Detection can miss details, and context can reveal identity. Review the whole document, not just highlighted matches.

BEFORE YOU GET STARTED

A few useful answers.

What does Offline Document Redactor do?

Offline Document Redactor is a desktop application that automatically finds sensitive information in documents, lets you review and redact or replace selected details, and saves a separate copy locally. It is designed for preparing documents before AI use or external review, starting with accounting and tax workflows.

Does it upload my documents to a server or AI service?

Document redaction is designed to run on your computer. There is no automatic upload of the source or the redacted copy to an AI service. This website does not accept document uploads. Initial installation and model setup may require a download; release instructions will specify the setup requirements.

Can I download it for Mac, Windows or Linux?

The app is in development, with macOS and Windows planned first and Linux later. Public installers are not available yet. Join the waitlist to request a launch notification; release details and system requirements will be shared when ready.

Which document formats are in scope?

The first-release focus is text-based, unencrypted PDF, ordinary DOCX and UTF-8 TXT or pasted text in English. Scanned PDFs, mixed-image pages, protected files and complex embedded content need explicit support. Spreadsheets and standalone images are outside the initial scope.

What kinds of information can I review?

The workflow combines local rules and entity recognition for names, organizations, contact details, addresses and structured identifiers such as tax IDs and account numbers. Country and domain choices affect coverage. Detection can miss values, so manual review and corrections remain essential.

Does replacing names guarantee anonymity?

No. Consistent placeholders can preserve useful relationships, but amounts, dates, locations and unusual events may still identify a person or organization. Review the entire document and decide whether its intended use or destination is appropriate.

Will it replace my original file?

The workflow creates a separate redacted copy and preserves the original. Check the exported document before sharing it. Keeping the original separate also lets you return to the source if you need to revise your decisions.

Is this an always-on privacy firewall or browser extension?

No. The initial product is a desktop document workflow that you deliberately start. It does not intercept browser uploads, prevent you from sending originals elsewhere or automatically submit documents to an AI service.

How much will it cost?

Pricing and license details have not been published. They will be provided alongside release information before a purchase or download decision.
