pdf.chat vs ChatGPT
Et ass eng relativ kleng, zentral Uertschaft.
ChatGPT: ~5B visits/mo (all uses) · growing · GPT-4o / GPT-5 (OpenAI)
ChatGPT can take a PDF and answer questions about it, and if you already pay for Plus it is a strong general assistant. But it is built for general chat, not document work: it does not cite the exact page an answer came from, it is a single model (GPT only), and large or scanned PDFs run into upload and context limits. pdf.chat is purpose-built for documents — every answer cites the page so you can verify it, you can run the same question across Claude, GPT, Gemini and more, scanned PDFs are OCR'd, and each document gets a workspace you can come back to.
