Context Crystal

Upload a file. Build shared understanding from it.

Select a file — a ZIP, a document (PDF, DOCX, XLSX), a text file (TXT, MD, CSV), or a video — and ask the first question. Distil prepares it on the server and returns a reusable context handle. Use it to address a situation, evaluate advice, support a proposal, or surface a risk with the evidence available for review.

Context Crystal

What a Context Crystal actually is

A Context Crystal is a prepared, reusable reference to your material — not a search index you query every time. You upload a source once; Distil compresses it into a durable handle. Every question after that runs against the prepared handle directly, instead of re-reading the original file from scratch.

How it's different from a typical "search your documents" AI tool

Most AI tools re-search your source material on every question — read the file, find the relevant passage, paste it into the prompt, repeat. That's search grounding (often called RAG), and it's good at pulling an exact quote.

A Context Crystal is prepared once. The AI's understanding of your material is already built into the handle, so it doesn't have to re-search or re-read the source for every question — it works from a durable reference instead. The two approaches pair well together: some questions need an exact quote (search), others need synthesis across the whole source (a prepared handle).

Two ways to use a crystal

  1. Inside PDC Dev Studio — ask questions against your crystal directly in the chat interface. No code required.
  2. As a handle in your own project — the same crystal is a context_handle you can call from your own application through the Distil API. Anyone can create a crystal without writing code; using it outside the Studio does require an API key.

What people use it for

  • Reviewing a proposal or contract against the full source material
  • Evaluating advice or a recommendation with the evidence on hand
  • Surfacing a risk buried in a large document set
  • Giving a support or research workflow durable memory of a source, instead of re-uploading it every session

Questions

Frequently asked

What is a Context Crystal?

A Context Crystal is a prepared, reusable reference to a document, codebase, or video, created by Distil. You upload the source once; questions after that run against the prepared handle instead of the raw file.

Is a Context Crystal the same as RAG?

No. RAG re-searches your source material for each question. A Context Crystal is prepared once into a durable handle, so it doesn't need to re-search the source every time. The two work well together — Distil supports both.

Do I need to know how to code to make one?

No. Anyone can create a Context Crystal on this page. Using the resulting handle inside your own application does require a Distil API key.

What can I upload?

A ZIP, a document (PDF, DOCX, XLSX), a text file (TXT, MD, CSV), or a video.

Where does my crystal live?

Server-side, as a hosted handle. You get a reference to query, not a downloadable copy of the prepared context.
