I put a chat-with-PDF tool on the web. Here's what the demo taught me.

I build small free tools, and most of them start as a question I ask myself. This one was: what if asking a PDF a question was as easy as opening a web page?

The web version of AI PDF Doctor does three things: you upload a PDF, you chat with it, and you can get a summary or a quiz on its contents. No install, no account. It runs on NVIDIA Nemotron via Nebius Token Factory.

Three things the demo taught me:

1. The quiz is the feature people remember. Summaries are useful; being tested on what you just read is what makes the knowledge stick.
2. Honesty is a feature. The tool is upfront that AI summaries compress information and can misread complex tables. Users trust a tool more when it says what it cannot do.
3. The browser is enough. For a demo, a web page that works beats an app store listing that takes a week.

The demo is live at https://ai-pdf-doctor-web.pages.dev. The Android app is in closed testing on Google Play and live on the Amazon Appstore. Try the demo, break it, and tell me what failed — that feedback is worth more than praise.
