ChatDOC

You need an account and have to sign in before you can use ChatDOC, so there is no anonymous drop-in option.

Once you are in, ChatDOC is an AI chatbot and PDF summarizer that extracts and summarizes information from your documents and answers questions about them in a chat format.

It reads text, tables and images, and it works with several document formats rather than only PDFs.

The feature worth noting is cited sources.

Answers come with references back to the original material, so you can check a claim against the page instead of trusting the summary.

You can also select a piece of content and ask the AI to analyze just that part, which helps with long reports where only one section matters.

Accuracy depends on the quality of the document, so a blurry scan or messy layout will likely give weaker results, and ChatDOC may not suit every type of document.

See it as a fast first pass, and verify the citations on anything important.
