Question 1

What is PDFLM?

Accepted Answer

PDFLM is a WordPress plugin that turns every PDF in your media library into a searchable, AI-answerable knowledge base. Your visitors ask questions in plain language; PDFLM answers in seconds, citing the exact source PDF and page each answer came from.

Question 2

How do I add AI search to PDFs on my WordPress site?

Accepted Answer

Install the PDFLM plugin from your WordPress admin, activate it, and PDFLM begins indexing every PDF in your media library — including scanned files, via built-in OCR. Drop the PDFLM block into any page or sidebar widget and visitors can start asking questions.

Question 3

Does it work with scanned PDFs?

Accepted Answer

Yes — PDFLM runs OCR during indexing so image-only PDFs become searchable alongside your text-native files.

Question 4

Where does the AI run? Where is my data stored?

Accepted Answer

On our managed infrastructure. Your original PDFs stay in your WordPress media library; PDFLM keeps an index and pointers — never copies of the documents themselves. Your archive remains under your control.

Question 5

Can I customise the chat UI?

Accepted Answer

It inherits your WordPress theme automatically — type, color, and spacing. You can override colors, copy, and layout via the block settings or your theme's CSS.

Question 6

What about new PDFs we upload later?

Accepted Answer

Auto-indexed. PDFLM watches your media library and picks up new uploads in the background — no manual sync.

Question 7

How is PDFLM different from ChatGPT, Claude, or Perplexity?

Accepted Answer

General AI tools can't read your library. ChatGPT and Claude need you to upload PDFs one at a time. Perplexity searches the public web. PDFLM reads every PDF in your WordPress media library and cites the source page on every answer, so visitors can verify it themselves.

Question 8

How much does PDFLM cost?

Accepted Answer

PDFLM has three paid plans plus an Enterprise tier. Starter: £29/month ($36) for 25 documents and 500 questions/month on 1 site. Pro: £79/month ($98) for 250 documents and 5,000 questions/month on 3 sites, with cross-encoder reranking and a signed DPA. Scale: £249/month ($310) for 2,000 documents and 30,000 questions/month on 10 sites, with white-label and 99.5% uptime SLA. Annual billing saves two months on every plan. Enterprise is custom-quoted.
