Redact Text From Documents Before Using AI
Prepare sensitive text safely before sharing, processing or using AI assistants
Why Document Redaction Matters
Documents often contain sensitive or confidential information.
This may include:
- personal data
- customer information
- medical records
- contracts
- financial details
- internal business communication
- research material
- private messages
Many people copy content from documents into ChatGPT, Claude, Gemini, Copilot, Grok or other AI assistants without realizing how much sensitive information is included.
Removing sensitive data before sharing or processing text helps reduce privacy, security and compliance risks.
Supported Input Methods
Redaxa allows users to work with text in different ways.
You can:
- paste text directly
- write text inside the editor
- import DOCX files
- import PDF files
- import ODT documents
- import EPUB files
- import HTML files
- import TXT files
This makes it easy to prepare text from many different sources before sharing or using it with AI systems.
How Redaxa Works With Documents
Redaxa imports and processes text extracted from documents.
The application does not visually edit or overwrite PDF or DOCX files directly.
Instead, users can import text from documents, detect sensitive information locally and prepare cleaned versions safely for sharing, anonymization workflows or AI-assisted tasks.
Example
Original Text
Patient Emily Carter visited the clinic in Manchester on 12 March 2026.
Please send follow-up information to [email protected].
Redacted
Patient [REDACTED] visited the clinic in [REDACTED] on [REDACTED].
Please send follow-up information to [REDACTED].
Pseudonymized
Patient [PERSON_1] visited the clinic in [LOCATION_1] on [DATE_1].
Please send follow-up information to [EMAIL_1].
The important context remains intact while sensitive information is removed locally before sharing the text.
Why Local Processing Matters
Many anonymization and AI privacy tools require users to upload documents or text to cloud services.
For sensitive information, this can itself become a privacy or compliance concern.
Redaxa works locally on your own PC.
No cloud processing. No external AI required. No document uploads.
This makes Redaxa suitable for:
- GDPR-sensitive workflows
- healthcare organizations
- legal departments
- research institutions
- business communication
- privacy-conscious users
- users working with confidential documents
