What your team can finally do.
Impossible with raw bytes. Automatic with Data Context Layer.
Researchers find work, not files.
Search by schema, statistics, or LLM summary. Last quarter's labeled dataset is one prompt away — instead of three engineer-days hunting through Slack for who built it.
Agents reuse, not regenerate.
Claude Code, Cursor, and Codex read schemas, previews, and lineage before they write code. Six hours of recompute become a six-cent read.
Recall replaces recompute.
Read a summary: $0.0001. Run a query: $0.20. Recompute from raw files: $100 and three hours of wall-clock. Same answer, four orders of magnitude apart.
Every result is reproducible.
Each .save() records source code, inputs, author, and time. Audit-ready by construction. A six-month-old experiment re-runs in one line of Python.
Three numbers that move when you adopt DataChain
No headcount changes. No new platform. The math comes from making compute reusable.
AI compute spend
10,000× cheaper
Recall vs recompute. Sense work (LLM annotations, embeddings, classifier passes) is the dominant line item in most AI budgets. CAST persists it once; every later question reads it.
Time to result
weeks → minutes
for questions a teammate already answered. Researchers find the dataset by schema, stats, or LLM summary instead of asking around.
Reproducibility risk
zero
lost experiments. Every dataset carries source code, inputs, author, timestamp, and lineage. Six months later, the result re-runs with one line of Python.
Why DataChain works
Four layers of unstructured data that researchers and AI agents read instead of rebuild.

What our customers say
“
We realized we were solving a problem we shouldn't be solving. With DataChain, what used to require data engineers is now handled seamlessly by researchers - and the whole team moved to the next level.
Yoni Svechinsky
Director of Research | brain.space
“
DataChain added real value to our workflows - versioned datasets, automated ETL, and MLOps, all in Python. If you need a data management layer on top of cloud storage, give it a try.
Nikhilesh Saggere
Lead Engineer | Alps Alpine Europe
“
What surprised me was how easily researchers adopted DataChain - data tools are usually hard for non-engineers. What surprised me more was when hardware and QA started asking for access too.
