Smallpdf is a PDF utility suite for compressing, converting, merging and e-signing files, built in Switzerland and used widely since 2013. It has added AI tools, including Chat with PDF and an AI summarizer, to that suite. AskYourPDF was built AI-first, around asking questions across one or many PDFs and getting answers with page-level citations. Here is how they compare for document research.
Quick Verdict: Choose AskYourPDF if your priority is conversational document research, source-cited answers and a broad set of AI writing tools. Choose Smallpdf if your main need is classic file manipulation, with AI as a secondary feature

I'm using this as a GPT-5.2 plugin. It has really streamlined my efforts to keep up with the literature in my field. Love it!

Seamless and quick. I have been supporting similar apps on Product Hunt, but this one seems to have the least downtime (maybe no one knows about it), but the customer service and accuracy of the LLM. data model and prompts seem to be above the rest of them. I would surely pay in the future to be apart of something great. In the meantime, I am loving the process and how this product saved me hours of reading time for a 125 page document. Best of luck and much success in becoming the next unicorn in the space.

I used this software for getting answers from various Trivia books. That way i can easily organize family game nights and ask questions from the app without having to go through the stress of browsing through for answers.\n I love it! Hopefully the free version remains effective in the long run.

Products like this will revolutionize knowledge retrieval. So much information out there, so little knowledge retrieved from it, until now.

This is a useful, highly intuitive tool that works very well! A couple of use cases I've explored: Ask a service contract which services are covered and when payment is due. Ask an eBook to summarize a concept that's spread over several chapters. This is AI your mom could use, and I mean that in the best way!

AskYourPDF is an amazing application. It blew my mind the first time I tried the application and started having a conversation with the document I uploaded. The application makes the process of reading and reviewing documents a really pleasant and fun experience.

Quite a substantial improvement in getting good answers from LLMs, especially for getting better summaries of papers than abstracts offer.
