Datasaur

Datasaur is a data labeling and LLMOps platform with NLP annotation (Data Studio) and LLM Labs, using a multi-model approach to speed labeling and cut costs by up to 70%.

Datasaur started as a specialized NLP data labeling tool and has expanded into a broader platform spanning annotation and LLM operations. Its Data Studio handles NLP labeling tasks like classification, NER, and span annotation, while LLM Labs provides tooling to build, evaluate, and ship LLM-powered applications and to use LLMs to accelerate the labeling process itself. A core theme is multi-model flexibility: Datasaur gives teams access to many models, including Claude, Llama, and GPT-family models, and claims its multi-model approach can cut costs by up to 70% while turning labeling projects that took a year into a few months. It is aimed at data scientists, ML engineers, and AI researchers who need efficient, high-quality labeled data and LLM workflows. Pricing spans both products. NLP labeling has a free plan plus Starter and Growth annual tiers and custom enterprise; LLM Labs offers a free pay-as-you-go plan, a Growth monthly plan, and custom enterprise, with flexible subscription or usage-based billing. This makes Datasaur suitable for teams ranging from small projects to large annotation and LLMOps operations.
