PDF Knowledge Base

Train Your Voice AI on PDFs

Your product datasheets, service manuals, policy documents, and price lists are already PDFs. Upload them and your voice agent answers callers straight from that content—no rewriting, no copy-paste. It reads the PDF, remembers it, and speaks the right passage back on demand.

PDFs Worth Uploading

The documents your callers ask about

Product Datasheets

Specs, dimensions, compatibility, model numbers—everything a buyer or support caller wants to confirm.

User & Service Manuals

Installation steps, troubleshooting, maintenance schedules. The agent walks callers through them by voice.

Policies & Terms

Warranty terms, returns, cancellation, SLAs—answered precisely from the policy document itself.

Price Lists & Quotes

Rate cards, package tiers, and discount rules so the agent quotes the right number every time.

FAQ Sheets

Existing FAQ PDFs become instant voice answers—no re-authoring required.

Brochures & Company Info

Locations, hours, service areas, and about-us material callers frequently ask for.

From PDF to Spoken Answer

What happens after you drop in a file

  1. Step 1 of 4: Upload the PDF

    Drag your PDF into the dashboard—up to 10 MB per file. Add as many as you need.

  2. Step 2 of 4: Text Extraction

    The system reads the text out of the PDF. Text-based PDFs (exported from Word, InDesign, or a design tool) work best.

  3. Step 3 of 4: Chunk & Embed

    The text is split into ~512-token passages with overlap and embedded with OpenAI text-embedding-3-small, then stored in a Pinecone index.

  4. Step 4 of 4: Ready in Minutes

    Processing finishes in about 1-5 minutes. The agent now retrieves from your PDF on the very next call.

Prep Your PDFs for Best Accuracy

A little cleanup goes a long way

Use Text PDFs, Not Scans

A PDF exported from a document keeps its selectable text. Scanned or photographed PDFs are just images—run OCR first to turn them into real text.

Split Very Large Files

The limit is 10 MB per file. A big master manual? Split it into logical sections and upload each—retrieval works just as well across several files.

Keep Text Selectable

Before uploading, try selecting text in your PDF viewer. If you can highlight it, the agent can read it. If not, it needs OCR.

Clean Headers & Footers

Repeated page headers, footers, and watermarks add noise. Trimming them helps retrieval find the passage that actually answers the question.

Prefer Real Tables to Images

Spec tables as actual text extract cleanly. A table saved as an image will not be read unless it is OCR'd first.

Re-Upload When It Changes

Replace an outdated datasheet or price list and the index refreshes in minutes—no retraining, no redeploy.

Example: Caller Asks a Manual Question

A datasheet PDF, answered live

  1. Step 1 of 3: Caller Question

    Caller: 'What's the maximum flow rate on the ProMax 500, and does it need a pre-filter?'

  2. Step 2 of 3: Semantic Retrieval

    The agent searches your uploaded datasheet PDF for 'ProMax 500' + 'flow rate' + 'pre-filter' and pulls the matching passages.

  3. Step 3 of 3: Grounded Answer

    Agent: 'The ProMax 500 has a maximum flow rate of 15 litres per minute, and yes, it needs a sediment pre-filter—that's on page 4 of the datasheet.'
