API for Deep Text-Based Psychological Insight

Detect NLP meta-programs, emotions, moods, and communication styles from any text. 🌐 Analyzes any language, returns any language. Plug the output into your product via a simple API.

What is IntenCheck?

IntenCheck is an API-first text analysis engine that detects NLP meta-programs, emotional states, and communication styles directly from natural language. It works as a language-agnostic server you can plug into any product to profile how people think, decide, and communicate in real time.

It turns raw text into rich psychological insight using NLP meta-programs, emotions, moods, and communication styles as its core dimensions. Instead of only measuring sentiment, it reveals where a person focuses attention (goals vs. problems), how they structure information (big picture vs. details), how they make choices (options vs. procedures), and how proactively they act. On top of that, it tracks dominant emotions, background mood and verbal style, giving you a multi-layered map of the author’s inner state.

How It Works

  • 1. Send Data

    Send text (or conversation logs) to the IntenCheck API.

  • 2. Multi-dimensional Analysis

    Receive structured JSON with meta-programs, emotions, mood, and communication style indicators.

  • 3. Take Action

    Use these signals to personalize content, coach users, segment audiences, or support human professionals.

Example Use Cases

  • 📈 Customer Reviews Analysis

    Automatic tone detection + recommendations. E-shop example: extract dissatisfied reviews and automatically suggest empathetic response templates.

  • 🤖 Chatbot Intent Recognition

    Real-time emotion & tone correction. Support example: if a client is aggressive, automatically adjust the chatbot's response to be more polite and accommodating.

  • ✉️ Marketing A/B Testing

    Tone comparison before publishing. Email marketing: "Version A is too cold, change to Version B with +20% more sincerity."

  • 👥 HR Communication

    Sincerity & tone checking. Employee feedback: filter out insincere or overly aggressive reviews before moderation.

🌐 All Languages – No Compromises

Native Analysis in Your True Language

  • Input text in EN, LT, RU, DE, FR...

    Send text in its native language. IntenCheck analyzes it precisely in that language without losing context through intermediate translation steps.

  • Get structured JSON in any language

    Need results for a Lithuanian team? Request "output_lang": "lt". Need them for global clients? Request "en". Get labels, tones, and recommendations exactly as you need them.
