Overview

The data foundation your AI models depend on

Most AI failures trace back to training data, insufficient coverage, inconsistent labeling, or missing edge cases. Solnix builds the annotation infrastructure, QA workflows, and delivery pipelines that turn raw data into model-ready datasets your teams can trust.

What's included

Image & Video Annotation

Bounding box, polygon segmentation, semantic segmentation, keypoint detection, and frame-level tracking for computer vision models across any domain.

Text & NLP Annotation

Named entity recognition, sentiment labeling, intent classification, coreference resolution, and instruction-response pairs for LLM training and fine-tuning.

Audio & Speech Annotation

Transcription, speaker diarization, emotion labeling, acoustic event classification, and phoneme-level annotation for speech AI systems.

Sensor & LiDAR Annotation

3D bounding box annotation, point cloud segmentation, depth map labeling, and multi-sensor fusion for autonomous vehicle and robotics datasets.

Quality Assurance & Agreement Scoring

Multi-pass QA workflows, inter-annotator agreement scoring, consensus labeling, and automated outlier detection, every dataset meets your threshold before delivery.

Annotation Pipeline Architecture

We design the full annotation infrastructure, tooling, workforce orchestration, quality scoring, and delivery pipelines, integrated with your model training stack.

Developer experience

Simple API. Powerful results.

Integrate in minutes with our SDK. Full TypeScript support, comprehensive documentation, and live examples for every feature.

How it works

From setup to production

01

Task Design

We analyze your model architecture, data distribution, and edge case requirements to design an annotation taxonomy and labeling guide.

02

Pilot & Calibration

A pilot batch establishes inter-annotator agreement baselines and calibrates quality thresholds before full-scale annotation begins.

03

Production Annotation

Annotation runs at scale with multi-pass QA, automated outlier flagging, and daily quality dashboards delivered to your team.

04

Delivery & Integration

Datasets are delivered in your preferred format (COCO, YOLO, TFRecord, JSONL) and validated against your training pipeline before handoff.
