TextInspector 1.0.2

TextInspector

TextInspector separates what was detected from what is actually risky.

A complete, standalone .NET text inspection library. TextInspector detects patterns, evaluates risk, preserves exact evidence and produces UI-ready reports. The free edition is fully functional on its own—not a trial, demo or feature-incomplete package.

Features

• 76 included detection rules, with context-aware evaluation.
• Separate detection and risk: recognized signals do not automatically become violations.
• Explainable risk reports with category findings, reasons and supporting evidence.
• Source-accurate highlights linked to the original text and report findings.
• Built-in masking, rule/category exclusions, raw-match helpers and sequential batches.
• Local, deterministic execution with no remote inspection service or usage quota.
• Supports .NET Standard 2.0, .NET 8 and .NET 10.

Install

dotnet add package TextInspector --version 1.0.2

Quick start

using TextInspector;

var inspector = TextInspectorEngine.Create();
var report = inspector.CreateReport("Contact us at hello@example.com.");

Console.WriteLine(report.HasDetections);                  // true
Console.WriteLine(report.RiskAssessment.TotalRiskPoints); // 0
Console.WriteLine(report.RequiresReview);                 // false

An ordinary email address is detected as supporting evidence without automatically increasing risk.

Read findings

foreach (var finding in report.Findings)
{
    Console.WriteLine($"{finding.Title}: {finding.RiskLevel}");
    foreach (var reason in finding.Reasons)
        Console.WriteLine(reason.Message);
}

For source-linked highlights and positions, use Inspect with TextInspectionOptions.IncludeHighlightSpans and IncludeSourceLocations, or use the report highlights.

ASP.NET Core

Install the optional TextInspector.AspNetCore companion package:

dotnet add package TextInspector.AspNetCore --version 1.0.2

using TextInspector.AspNetCore;

builder.Services.AddTextInspector(options => options.EnableMasking = true);
