PDF AI vs Konjer

PDF AI lets you upload a PDF and ask questions in plain language, with cited answers pulled from the document text. The web app handles chat across books, legal contracts, financial reports, and research papers, while a Chrome extension adds the same chat panel to local files, Google Drive, and Dropbox PDFs. Developer APIs at api.pdf.ai parse documents into JSON, extract custom fields, and split files by section.

Most PDF chat tools stop at Q&A. PDF AI also ships a Parse API (POST /api/v2/parse), Extract API for invoice and form fields, and Split API for section-aware document breaks. Ultimate and Enterprise plans add specialized AI Agents for verticals like lease review, tax documents, and medical records, plus Capture and Ask screenshot questioning. SOC 2 Type II storage and a private-document mode that skips cloud retention address teams handling sensitive files.

Researchers, legal teams, and financial analysts use the chat interface for one-off document review. Developers embed the REST APIs into automation pipelines, with commercial API credit packs starting at $50 per month for 1,000 credits. The free Hobby plan allows 1 PDF upload and 100 questions per month to test the workflow before upgrading.

Konjer is a chat library where books become conversational partners instead of static files. The site calls itself a library full of books you can talk to, and the portal welcomes visitors to chat with any title in the collection.

Unlike a PDF reader or a general-purpose chatbot, Konjer lists each book with a short topic blurb before you open a chat. The portal shows nonfiction titles like The Mom Test and Sapiens, so you choose a work and then ask questions in dialogue form.

Konjer fits curious readers who want to probe ideas through back-and-forth conversation rather than linear reading. Students and self-learners exploring business or science books can use it as a lightweight study companion when they want a title to answer follow-up questions.
