How to Use LogLenx

🚀Getting Started

LogLenx helps you quickly understand any error, log output, or stack trace and get actionable fixes — no setup required. It works with any language, framework, or platform.

1. Create an account — click "Get Started Free" to register with your email.
2. Paste your content — paste any error message, log output, stack trace, build failure, or terminal output into the text area.
3. Click Analyze — LogLenx detects patterns like exceptions, build errors, database issues, network failures, and more.
4. Review results — see grouped issues, severity levels, and suggested fixes for each problem.

📋Paste & Analyze

The simplest way to use LogLenx. Paste any content — error messages, stack traces, build output, terminal logs, browser console errors, or even config snippets — into the text area and click Analyze.

LogLenx detects 25+ pattern types including:

Each detected issue gets a severity label (Critical, Error, Warning, Info) and suggested fixes or commands to resolve it.

🤖AI Deep Analysis

After running a standard analysis, click AI Deep Analysis to get a thorough AI-powered breakdown. Works with any content — error messages, logs, build output, or even screenshots.

The AI identifies root causes, assesses severity, and provides:

1. Root Cause — explains why the issue is happening, not just what the error says.
2. Severity Assessment — rates the impact with justification.
3. Immediate Actions — copy-paste ready commands to fix or mitigate right now.
4. Investigation Steps — deeper debugging steps if the immediate fix doesn't resolve it.
5. Prevention — recommendations to avoid recurrence.

After the AI analysis, you can use the Follow-up Chat to ask clarifying questions — the AI remembers the full context of your logs and analysis.

📁File Upload

Instead of pasting, you can upload log files directly. Supported formats include .log, .txt, .json, .csv, .xml, .yaml, and .zip archives.

1. Click the Upload button or drag and drop files onto the upload area.
2. The file content is extracted and placed into the log text area.
3. Click Analyze to process the uploaded logs.

💻Codebase-Aware Debugging

Upload your source code alongside error logs so the AI can cross-reference errors with your actual code.

1. Click Upload Codebase and select a .zip file of your project source.
2. Paste your error logs into the text area.
3. Run AI Deep Analysis — the AI will point to specific files where issues originate and provide copy-paste code fixes.

Supports all major languages: Python, JavaScript/TypeScript, Java, Go, Rust, C++, and more. Skips node_modules, .git, and other build artifacts automatically.

🖥️Live Screen Capture

Share your screen to capture logs in real-time — useful for monitoring live systems or terminals you can't easily copy from.

1. Click Start Screen Capture and select the window or screen to share.
2. LogLenx captures frames every 2 seconds and runs OCR to extract text.
3. Extracted text is automatically deduplicated and appended to the log area.
4. Click Stop Capture when done, then Analyze the captured text.

📤Exporting Reports

After analysis, export your results in three formats:

📚History & Saved Analyses

LogLenx automatically saves your last 20 analyses in your browser for quick access.

1. Click Analysis History to open the history panel.
2. Click any past analysis to restore it — the full results load instantly.
3. Click the star icon to save an analysis permanently to your account (stored in the cloud).
4. Saved analyses persist across devices and browser sessions.

🔀Comparison Mode

Compare two sets of logs side-by-side to spot differences — useful for comparing "before and after" deployments or different environments.

1. Run an analysis on your first set of logs.
2. Enable Comparison Mode from the tools panel.
3. Paste a second set of logs and analyze again.
4. LogLenx highlights differences between the two result sets.

🎯Custom Pattern Rules

Define your own detection rules for application-specific log patterns that LogLenx doesn't cover out of the box.

1. Open Settings and navigate to Custom Patterns.
2. Add a regex pattern, give it a name, and choose a severity level.
3. Your custom patterns are applied alongside the built-in detectors during every analysis.

🔗Sharing Reports

Generate a unique shareable link for any analysis result — perfect for sharing with teammates who don't have LogLenx accounts.

1. After running an analysis, click the Share button.
2. A unique link is generated and copied to your clipboard.
3. Anyone with the link can view the report — no login required.
