Pretrained text classifier

Identify rude text with one API call.

A pretrained rude text classifier that sorts text into one of 2 categories. Use the rude text API immediately, no training required, then adapt it to your own data when you need more.

What this rude text classifier recognizes

A sample of the 2 labels this pretrained classifier chooses between.

Not Rude
Rude

Call the rude text API

Get your own copy of this classifier behind your own endpoint — callable from any HTTP client:

API quick start
curl -X POST "https://www.nyckel.com/v1/functions/YOUR_FUNCTION_ID/invoke" \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"data": "The text you want to classify"}'

Example response

{
  "labelName": "Not Rude",
  "labelId": "label_...",
  "confidence": 0.92
}

Under the hood

Model type
Nyckel-trained

Trained on a Nyckel-curated dataset covering 2 rude text categories, served on Nyckel's own infrastructure — your text snippet stays on Nyckel.

Input
Text

Send raw text to the invoke endpoint; the response is a label with a confidence score.

Make it yours
Adaptable

Clone it, then correct predictions and add your own samples in the console — Nyckel retrains automatically, turning this into a custom model tuned to your data.

More than a demo: this page is one of thousands of pretrained functions on Nyckel, an ML classification platform. You can invoke classifiers by API, review predictions, correct labels, collect samples from production traffic, and promote any pretrained function to a private custom model — without changing your integration.

Where teams use rude text classification

Social Media Monitoring

Businesses can use this function to monitor and filter out offensive or inappropriate comments and posts on their social media platforms to maintain a positive and respectful digital environment for their audiences, ensuring their brand image is maintained.

Work Communication Etiquette

The function can be integrated within an organization’s internal communication tools to automatically flag and report any disrespectful or unprofessional language in email or chat conversations, promoting a positive workplace environment.

Customer Feedback Analysis

It can be used to categorize user generated content such as comments, reviews, and emails as rude or not, assisting customer service representatives in prioritizing and better responding to customer concerns.

Content Moderation in Forums & Discussion Boards

Forums and discussion boards can use this function to identify and block offensive content before it's publicly visible, reducing the risk of verbal confrontations and maintaining civil discourse.

Chatbot Interaction

This function can be employed in AI-powered chatbots to ensure they don’t respond to messages that contain offensive language, reducing the chances of inappropriate interactions.

Cyber Bullying Prevention

Online platforms geared towards younger audiences can utilize this function to detect and prevent bullying or cyber harassment by identifying abusive or threatening language.

AI Training

Training AI and machine learning models to understand human language and respond appropriately is essential. This function can be utilized to classify and filter out rude texts to ensure that the AI is not learning or replicating disrespectful language.

Common questions

What's the difference between a zero-shot and a Nyckel-trained classifier?

A zero-shot classifier uses a large foundation model's general knowledge to pick between your labels — no task-specific training, so new or edited labels work immediately. A Nyckel-trained classifier has been trained on labeled examples and runs on Nyckel's own infrastructure, which typically makes it faster, cheaper per call, and more accurate on data that resembles its training set. The "Under the hood" section on this page shows which kind this classifier is, and any classifier can be adapted into a trained one by adding your own examples.

How do I know whether this will work for my application?

Honestly: we can't know in advance — it depends on your data stream and how closely it resembles what this classifier has seen. The reliable way to find out is to measure it on your own data: start invoking the classifier with real traffic, or upload and annotate a set of text samples in the console — make sure they look like your production data, not idealized examples. Nyckel's evaluation metrics then show you exactly how it performs on that data before you rely on it.

What happens when it makes a mistake?

No classifier is perfect, so Nyckel is built around the correction loop: invokes can be captured for review, you confirm or correct predictions in the console, and corrections become training data. Over time the model adapts to your data distribution — accuracy on your traffic improves with use rather than staying fixed.

Do I need training data to get started?

No. This rude text classifier works out of the box — clone it into your console and you'll have your own API endpoint in under a minute. Training data only enters the picture when you want to adapt it: your corrected predictions and uploaded samples improve the model, and you can also edit the label set to match your needs.

What does it cost to try?

Trying the classifier on this page is free with no signup. Cloning it requires a free account, and the free tier covers your first API calls each month — see nyckel.com/pricing for current limits and paid tiers.

Ready to classify rude text at scale?

Add this pretrained classifier to your Nyckel console — you'll get a live API endpoint in under a minute, and a path to a custom model when you need one.
