NLP Pro
Key phrases, aspect sentiment, custom classification (zero-shot), entity linking, and conversational PII.
The capabilities that take Azure AI Language and AWS Comprehend from "basic" to "useful" — at a fraction of the price.
Interactive NLP Suite Endpoint Playground
Test all 5 language endpoints in real time. Inspect deterministic JSON responses and millisecond execution metrics.
Unified Language Intelligence vs Hyperscaler Sprawl
Building modern production applications typically requires juggling 4 to 6 disparate vendor services for entity linking, PII sanitization, and classification—each with separate authentication keys, variable rate limits, and enterprise commit floors. Brainiall NLP Pro consolidates the entire language pipeline into a single high-performance API key.
What you get
/v1/nlp/keyphrasesKey Phrases
Top-N ranked phrases from text via statistical scoring (TF + position + casing + stopword filter). No ML model, predictable cost, blazing fast.
/v1/nlp/sentiment/aspectAspect Sentiment
Per-aspect sentiment scoring. Send a product review + aspects like [camera, battery, screen, price] and get a per-aspect verdict with mention spans.
/v1/nlp/classify/customCustom Classification (zero-shot)
Define your labels at call time — no training data, no model upload. Returns predicted label + per-label scores. Single or multi-label.
/v1/nlp/entities/linkEntity Linking (a public knowledge base)
Detect entities AND link each one to its canonical a public knowledge base Q-id, label, and description. Disambiguate "Apple" the company from "apple" the fruit.
/v1/nlp/pii/conversationConversational PII (multi-turn)
Detect PII across a multi-turn dialogue with cross-turn coreference. Same email, name, or ID gets the same stable entity_id no matter how often it appears.
When NOT to Use NLP Pro Endpoints
- Open-ended conversational chat generation: NLP Pro provides deterministic structured classification, extraction, and PII masking endpoints. For agent reasoning and long-term memory, use our Agent Infrastructure family.
- Scanned document and PDF image OCR: If your input is an unparsed PDF or image scan, use Document Intelligence family to extract text and layout before submitting text to NLP Pro.
- Heavy audio transcription: Send raw audio to our Audio & Speech family first to generate transcripts, then pipe transcripts to NLP Pro for aspect sentiment or PII scrubbing.
