Broad sensitive-data detection
Detects sensitive values in pasted text, including names, emails, phone numbers, IBANs, social security numbers, addresses, IDs, medical information, passwords, API keys, and company-specific terms.
ONYRI Sanitize
ONYRI Sanitize is a browser-based tool that anonymizes sensitive text and tables before you send them to an AI assistant, then restores the response locally. It helps individuals and teams use AI with less risk of exposing private, financial, or company data.
Browser-based prompt sanitization for AI
ONYRI Sanitize is a browser-based anonymization tool for preparing prompts, text files, and tables before sending them to an AI assistant. It scans for sensitive information such as names, emails, phone numbers, IBANs, passwords, API keys, and company identifiers, then replaces those values with reversible tokens so the original content can be restored after the AI responds.
The product is designed to keep processing local: the site says the engine runs in the browser, no text is sent to the server during sanitization, and the mapping between tokens and original values stays on the device. That makes it aimed at people and teams that want to use AI while reducing the risk of exposing private, internal, or regulated data.
What ONYRI Sanitize does
Tokenize and restore workflow
Replaces each detected value with a reversible token so you can send a cleaned prompt to an AI model and restore the response afterward.
Custom rules
Lets you define your own regex-based patterns and assign a dedicated color for internal references, business identifiers, or other custom data.
Text and table processing
Supports text as well as CSV and Excel files, with tokenization applied column by column for tabular data.
Large-volume handling
Moves processing to a dedicated worker beyond 1,000 rows so the interface stays responsive on larger datasets.
Reusable profiles and team workspaces
Lets you save detector and rule combinations as reusable profiles, and share rules and profiles across a team workspace.
Practical ways to use ONYRI Sanitize
Sanitize support tickets and customer requests
Before pasting a customer ticket into ChatGPT or another assistant, the tool replaces names, email addresses, IBANs, and phone numbers with tokens so the AI only sees anonymized placeholders.
Protect spreadsheet data before AI analysis
When preparing an HR or internal spreadsheet for analysis, you can drop in tabular data and tokenization applies column by column instead of sending raw identifiers to the model.
Standardize team policy
Teams can define shared rules and profiles so everyone in the workspace applies the same anonymization policy when working with internal prompts.
Cover company-specific identifiers
If your organization uses internal references, business IDs, or other fields not covered by the default detectors, you can add regex-based custom rules to catch them before export.
Reuse the same sanitization setup
For repeated workflows, you can save a detector-and-rule setup as a reusable profile and apply it again in one click for future sessions.
Pros and Cons
Pros
- Runs 100% in the browser with no processing requests sent to the server.
- Covers a wide range of personal, financial, secret, and company-specific data types.
- Supports both freeform text and tabular files such as CSV and Excel.
- Includes custom rules, reusable profiles, and shared workspace policies for teams.
- Provides a reversible tokenization workflow, so the AI sees anonymized text while the user keeps the mapping locally.
Cons
- The product only works in the browser, so the workflow depends on a local browser session and the mapping disappears on refresh.
- The source does not show native integrations with external apps or export formats beyond cleaned text and restored responses.
- Advanced team features such as SSO, SCIM, audit logs, and a DPA are only listed on higher-tier plans.
FAQ
Does my data go through ONYRI Sanitize servers?
No. The site states that tokenization runs 100% in your browser and that no text, file, or token-to-value mapping is sent to the server during processing.
What happens if I close the tab or refresh?
The mapping lives in memory and disappears on refresh. The site says nothing is persisted, so a closed tab or reload clears the anonymization state.
What if the engine misses something?
Detections are visible and editable before export, and custom rules can cover cases specific to your work.
Can my team use the same rules?
Yes. Rules and profiles are shared per workspace so teams can apply the same anonymization policy.
Do I need a card for the Pro trial?
For the 7-day Pro trial, the site says a card is saved when you choose a plan, but €0 is charged during the trial and you can cancel before it ends.
