AskYourPDF

Chat with documents

Upload a PDF, DOCX, EPUB or TXT file, or paste a URL, and ask questions in plain language. Each answer cites the page it came from, and the site says it works in more than 100 languages.

Knowledge Bases

Premium and Pro group documents into a Knowledge Base, so that one question draws a single cited answer from every file in it.

Choice of AI models

The free plan runs on GPT-5 Mini. Paid plans add GPT-5, GPT-5.2 and Gemini 2.5 Flash, while Claude 4.5 Sonnet, Claude 4.5 Opus and Gemini 2.5 Pro draw on credits.

AI Agent for websites

Trains a chatbot on your website and uploaded files and embeds it with one line of code. Visitors can open a support ticket when the agent cannot answer.

AI form filler

Fills fillable and non-fillable PDF forms using data taken from another PDF, a text file or pasted content.

Developer API

Adds documents by upload or URL and answers questions about them. API plans are separate: free with 100 messages, or $49.99 a month for 6,000 messages and 60,000 pages.
