# Knowledge Base

> Upload documents so the AI can answer detailed patient questions from your own content

The knowledge base lets you give the AI additional information about your clinic beyond the basic profile fields. Upload any PDF document — a price list, service brochure, doctor bios, or FAQ — and the AI will read it and use it when answering patient questions.

## What to upload

Any document that contains information patients commonly ask about is a good candidate:

* **Price lists** — consultation fees, procedure costs, lab test prices
* **Service descriptions** — what treatments or procedures your clinic offers
* **Doctor bios** — education, experience, and areas of expertise for each doctor
* **FAQ documents** — common questions your receptionist already answers manually
* **Preparation instructions** — what patients need to do before certain visits

<Info>
  The AI does not read image-only PDFs (scanned documents without selectable text). Make sure your PDFs have actual text content, not just images of text.
</Info>

## Uploading a document

<Steps>
  <Step title="Go to the knowledge base">
    Navigate to **Dashboard → Knowledge Base** (or **Dashboard → AI → Knowledge**).
  </Step>

  <Step title="Click Upload">
    Click the upload button and select a PDF file from your computer.
  </Step>

  <Step title="Wait for processing">
    Kashfy extracts and indexes the text from the PDF. This usually takes under a minute.
  </Step>

  <Step title="Test it">
    Go to **Dashboard → AI → Test Chat** and ask a question that should be answered from your document. Verify the AI responds correctly.
  </Step>
</Steps>

## How the AI uses documents

When a patient asks a question, the AI:

1. Checks if your knowledge base documents contain relevant information
2. If yes, references that content in its answer
3. If no, falls back to the clinic profile and doctor data it already has

The AI does not quote documents verbatim — it uses the information to compose natural-sounding responses.

## Managing documents

From **Dashboard → Knowledge Base** you can:

* **View** all uploaded documents with their upload date
* **Delete** documents you no longer want the AI to reference

<Warning>
  Deleting a document removes it from the AI's knowledge immediately. If a document contained information patients frequently ask about, removing it may cause the AI to say it doesn't know the answer.
</Warning>

## Tips for better results

<Tip>
  Keep documents focused. A PDF dedicated to "Pricing" will perform better than a single large file covering everything. The AI is better at finding specific information in shorter, well-structured documents.
</Tip>

<Tip>
  Use clear headings and organized formatting in your PDFs. The AI reads the text linearly, so well-structured content is easier for it to use accurately.
</Tip>

## Limitations

* **Maximum file size:** Documents must be under 10MB per file
* **File format:** Only PDF is supported currently
* **Language:** Documents can be in Arabic or English. The AI handles both.
* **Scanned PDFs:** Not supported — the text must be selectable
