# What is TopK?

> Turn your documents into reliable context for agents and humans.

TopK is an end-to-end solution that turns unstructured documents(PDFs, Images, Markdown, HTML) into reliable context for agents and humans.

You can search, explore, and extract relevant information from your documents, all grounded in the source material.

We believe that **context is a search problem.** Agents need relevant data to make the right decision. Without the right context, even the best AI models fall short — garbage in, garbage out.

## How it works

<Steps>
  <Step title="Ingest" icon="upload">
    Upload your documents via the CLI, Python SDK, or JavaScript SDK. TopK supports PDFs, images, markdown, HTML, [and more](/core/ingest#supported-formats).
  </Step>

  <Step title="Process" icon="zap">
    TopK parses, chunks, and indexes your documents—preserving structure from tables, charts, and complex layouts.
  </Step>

  <Step title="Query" icon="search">
    Ask questions, search for relevant passages, or run complex research queries across your documents.
  </Step>

## Use cases

* **AI agents & copilots** — ground your agents' context in private knowledge to reduce hallucinations and improve decision quality.
* **Document-heavy workflows** — automate extraction and Q\&A over contracts, filings, research papers, and more.
* **Enterprise knowledge bases** — give employees instant, cited answers from internal documentation, policies, and reports.
* **Customer support** — surface the right answers from your knowledge base instantly, at scale.
