Datachain

Context Layer for Unstructured Data

Your researchers and AI agents are flying blind in S3

Every LLM, embedding, or classifier pass over your files runs once. The next read costs cents. Your data stays in your cloud; compute runs in your VPC. SOC 2 Type II.

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.

  • 10,000× cheaper

    AI compute spend. 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.

  • weeks → minutes

    Time to result. Find answers a teammate already produced. Researchers locate datasets by schema, stats, or LLM summary instead of asking around.

  • zero

    Reproducibility risk. Avoid 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

CAST · Container  /  Asset  /  Sense  /  Task

Four layers of unstructured data that researchers and AI agents read instead of rebuild.

  1. Storage

    Sensor data · Videos · Images · Logs · Docs

    S3 · GCS · Azure

    Your cloud

  2. Container

    h5/jpg/mp4 file headers · JSON sidecars · joint metadata

    cheaper to recall

    20×

  3. Asset

    audio tracks · frames · clips · np.array · dataset mixtures

    cheaper to recall

    400×

  4. Sense

    ML scoring · LLM responses · embeddings

    cheaper to recall

    10,000×

  5. Task

    insights · curated datasets · data analytics

    cached forever

    Instant

In the tradition of Codd (1970), Kimball (1996), Iceberg (2017) — applied to data they never saw

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.

Distributed Python over your files

Read, transform, and save data at scale. In your own cloud (BYOC).

pipeline.py
import datachain as dc

(
    dc.read_storage("s3://acme-robots/runs/**/*.mp4")
    .filter(dc.C("file.size") > 1000)
    .settings(parallel=8, prefetch=5, workers=700)
    .map(obstacles=detect_obstacles)
    .save("obstacle_detections")
)
  • Scale Run the same Python pipeline on your laptop or across 700 workers.

  • Parallelism Combine parallel Python functions with async I/O across S3, GCS, and Azure.

  • Resilience Resume from automatic checkpoints and process incremental updates without starting over.

  • Files in storage Keep original files in your cloud and work with pointers, without copying data.
