data for language models

Model quality starts with data

We are a team of data engineers. We prepare the documents and data language models run on: corpora, datasets, structuring for RAG and fine-tuning.

Quality starts long before the first prompt.
why data

Quality starts long before the first prompt.

A model answers with exactly what is in its data. If documents are gathered without structure, with duplicates and junk — neither model choice nor prompts will help. We put documents and data in order beforethey reach your RAG system or training pipeline.

From raw documents — to ready data.
how we work

From raw documents — to ready data.

We collect and clean corpora, structure documents, annotate examples and check quality at every step. The output is production-ready data, with process documentation.

  • Corpus and dataset collection and cleaning
  • Chunking and metadata for RAG
  • Example validation for fine-tuning

Got documents or data that need preparing for an LLM?
Tell us what documents and data you have and what task they are being prepared for. We will propose a preparation plan and estimate the effort.

What we prepare for language models

Corpora and datasets

We build text corpora from your sources and open data, clean duplicates and junk, annotate for the task. The output is a ready-to-use dataset.

Corpora and datasets
We collect, clean and annotate text corpora and datasets for model training and fine-tuning tasks.
Documents for RAG
Documents for RAG
We structure documentation for retrieval-augmented generation: chunking, metadata, retrieval quality.
Fine-tuning preparation
Fine-tuning preparation
Instruction and domain datasets for fine-tuning: formats, templates, example validation.
Data quality control
Data quality control
We check completeness, consistency and cleanliness: deduplication, quality metrics, sample audits.
Text extraction
Text extraction
We extract text from PDF, DOCX, HTML and scans: tables, structure — without losing meaning or adding junk.
Data readiness audit
Data readiness audit
We assess whether your data is fit for RAG or training and what to fix: an issue map and a preparation plan.
