1. Why protect sensitive text before using AI?
AI tools can help draft, summarize, translate, organize, and analyze professional text. The same text may also contain names, contact details, dates, financial values, client information, internal identifiers, credentials, project references, or other confidential details that are not necessary for the AI task.
A privacy step before AI use helps separate the useful meaning of the text from the sensitive values inside it. Instead of sending every original value, you can work with a protected version that preserves context through placeholders such as [PERSON_1], [DATE_1], [AMOUNT_1], or [SECRET_1].
This is useful when the AI needs to understand the structure and purpose of the text but does not need the real identity, account number, access credential, or confidential reference.
2. What anonymization, redaction, masking, and tokenization mean
The terms anonymization, redaction, masking, and pseudonymization are often used interchangeably in searches, but they do not describe exactly the same process.
Irreversible anonymization
True anonymization generally aims to prevent information from being linked back to an identifiable person. It is not designed for restoring the original values later.
Redaction
Redaction removes or obscures information. A permanently redacted value may no longer be available in the resulting text.
Masking
Masking hides all or part of a value, such as displaying only the final digits of an account number.
Reversible tokenization
Layrin uses reversible local tokenization. Sensitive values become structured placeholders, while original values and their mappings remain on your device for local restoration.
Unlike irreversible anonymization, this workflow intentionally preserves a local mapping so supported values can be restored after the AI responds.
3. How Layrin’s local-first workflow works
The workflow follows four clear stages:
Protect locally
Paste the text into Layrin. The local protection engine identifies sensitive values and replaces them with numbered placeholders. Original values and their mappings remain on the device.
Review
Review the protected text before it is used with AI. You can verify the detected values and manually protect text that requires additional attention. Review is important because professional context can be subtle and no automated detector should be treated as infallible.
Use AI
With Layrin Protect, copy the reviewed protected text into the AI tool or workflow you already use. With Layrin Pro, keep the protected drafting workflow inside Layrin through the managed AI experience.
Restore locally
After the AI response is available, Layrin restores recognized placeholders with the original values on the device. The restored result can then be reviewed and copied for its intended use.
Protect locally → Review → Use AI → Restore locally
4. What types of sensitive information can be protected?
Depending on the wording and context, Layrin is designed to detect or help you manually protect information such as:
- People and contact information, including names, email addresses, and phone numbers
- Dates, locations, and postal addresses
- Financial values, account details, and business identifiers
- Legal, clinical, research, and project references, including matter, participant, and specimen identifiers
- Credentials, secrets, access keys, URLs, paths, hosts, and other technical resources
- Other confidential values selected during review
Detection results depend on the text, language, formatting, and context. Layrin’s review and manual-protection controls are part of the privacy workflow, not optional decoration.
5. From short emails to longer professional reports
Layrin is not limited to a single sentence or a short email. The same protect-and-restore workflow can be applied to longer professional text pasted into the application.
Emails and messages
Protect names, contact details, dates, amounts, confidential references, and source signatures before drafting or revising a message.
Reports and meeting notes
Replace participant names, projects, decisions, budgets, timelines, and internal references while preserving the structure needed for summarization or analysis.
Contracts and legal drafts
Protect client information, parties, matter references, contract identifiers, financial values, addresses, and selected confidential clauses in pasted legal text or contract excerpts.
Clinical and research text
Protect patient-related references, participant identifiers, dates, study information, specimen references, and research project details before using AI for an appropriate reviewed task.
HR and employee information
Protect candidate names, employee details, compensation values, workplace references, dates, and internal identifiers in recruiting or workplace text.
Financial, operational, and technical text
Protect amounts, account details, business identifiers, project codes, infrastructure references, secrets, and operational information before requesting AI assistance.
Layrin currently works with text pasted into the application. Direct PDF, Word, spreadsheet, image, and OCR import are not currently offered.
6. Layrin Protect and Layrin Pro
Layrin Protect
Protect is for people who want to keep using their existing AI tools. Layrin protects and reviews the text locally, you copy the protected version to the AI workflow you choose, and you restore the response locally in Layrin.
Layrin Pro
Pro provides the integrated managed AI workflow. The text is protected and reviewed before the managed request, and original sensitive values and local mappings remain on the device. The protected content required for the task is processed through the managed Layrin service, then the response is restored locally.
Both plans use the same core principle: original sensitive values should not be included in the AI task when a protected placeholder can preserve the necessary context.
7. Why human review still matters
Professional context can make a project nickname, unusual identifier, internal reference, or organization-specific phrase confidential even when no clear label announces it.
Review the protected text before AI use and correct any missed value, ambiguous token, or classification that needs additional judgment.
8. Current scope and responsible use
Layrin currently works with pasted text as a local-first privacy gateway. It is not a general chat application or a substitute for professional legal, clinical, security, or privacy review.
- Detection may miss a value or protect more text than necessary.
- Use manual protection for values requiring additional judgment.
- Compliance with laws, policies, contracts, and professional obligations still depends on the user, organization, task, and chosen workflow.
- Choose an AI provider and workflow appropriate for your organization and task.
Use professional judgment for the content, AI output, and decisions involved in the task.
9. Frequently asked questions
How do I anonymize text before ChatGPT?
Paste the text into Layrin, protect and review the sensitive values locally, then use the protected version through Protect or Pro. Supported placeholders can be restored locally after the AI responds.
Is Layrin a PII-redaction tool?
Layrin can detect and replace many types of personally identifiable and confidential information. It uses reversible local tokenization, which differs from permanent redaction or irreversible anonymization.
Does the AI see the original sensitive values?
With Protect, you choose where to use the reviewed protected text. With Pro, reviewed protected content uses the managed workflow while original values and mappings remain local.
Can Layrin restore values in the AI response?
Yes. When the response contains supported Layrin placeholders, the application can restore their original values locally on the device.
Can I use Layrin with longer text?
Yes. The workflow supports longer professional text such as reports, notes, and contract excerpts; review remains important for every task.
Can I upload a PDF or Word document?
The current workflow uses pasted text from an email, report, contract, note, or other source. Direct file import and OCR are not currently offered.
Does Layrin guarantee that every sensitive value is detected?
No. Detection can miss or overprotect a value, so Layrin includes Review and manual-protection controls for inspection and correction.
