AI-assisted data annotation companion for faster, smarter labeling
The extension proposes likely labels or annotations as you work, so you can confirm a suggestion instead of classifying each item from zero.
Runs entirely in the browser via the Chrome Web Store, with no server setup, plugin dependencies, or account creation required.
Acts as a companion layer over the annotation pages you already use, so there is no need to migrate your dataset or tooling.
The developer declares that user data is not sold or shared and is not used for unrelated purposes.
Human-validated training data and evaluation services for frontier AI models
Chain-of-thought reasoning traces, SME-level RLHF, supervised fine-tuning demonstrations and adversarial red teaming for the most capable models.
Golden trajectories, RL environment design, failure-mode taxonomies and software-engineering-driven deep evaluation for autonomous agents.
Multilingual ASR and conversational speech data, expressive TTS annotation, vision-language model training data, video action labelling and voice-agent evaluation.
LiDAR point-cloud labeling, multi-camera sensor fusion, robot demonstration trajectories, world-model rollouts and embodied interaction logs.
SpecialistConnects teams directly with verified human participants for preference tuning and studies, but lacks managed end-to-end labeling pipelines.
