| Key features | - Monitor AI agent conversations without code by connecting Langfuse or LangSmith
- Judge conversations on six criteria: accuracy, goal alignment, decision quality, completeness, helpfulness, and factuality
- Create code-based rules that block risky actions before they run
- Group failures into problems with suggested rules and failure counts
- Send Slack alerts for serious mistakes and reply checks immediately
- Add to agents with one line of Python code for OpenAI Agents SDK, LangChain and LangGraph
- Mask sensitive data like email addresses, phone numbers and card numbers before sending to Kalytera
- Rules continue running offline if Kalytera goes down
- Correct judge verdicts by marking conversations as passed or failed
| - Sentence-level highlighting of AI-like text
- Paste text or upload files (.txt, .docx, .pdf)
- Detects patterns from ChatGPT, GPT-6, Claude, and Gemini
- No sign-up or account required
- Private text processing
- Minimum 50 words required for checking
- Identifies repetitive vocabulary and generic wording patterns

|---|
| What makes it different | - Rules are code-based, not AI, so they cannot be overridden or argued with
- No code setup using Langfuse or LangSmith connections for immediate visibility
- Rules continue protecting agents even when Kalytera is offline
- Catches exact mistakes from real AI agent incidents like database deletes, account takeovers and crypto theft
- Customer data stays on your servers; Kalytera only reads conversations, never writes or stores sensitive data
| - Sentence-level highlighting shows exactly which parts appear AI-generated, not just a percentage
- Detects multiple AI models including ChatGPT, Claude, and Gemini
- Optimized for ChatGPT and newer GPT-6 style text
