Ask questions about your PDFs and scans on Android

Instead of scrolling through pages to find one number or date, you can ask your documents a question in plain words. This guide explains what that looks like, what to expect, and how NEXO Chat does it on your phone.

What kind of questions work

"How much do I need to pay?" or the total on an invoice
"Until when is my cover valid?" or when something expires
"Where am I flying to?" or when a trip starts
Who issued a document, or an address inside it
A short summary of a long document

What to look for in any document-chat tool

Sources you can check. An answer without a page reference is hard to trust, especially for amounts and dates.
Honest "not found" answers. A good tool says it can't find something instead of guessing.
Where your documents go. Many AI tools upload files to a server. Check whether your documents and questions leave the device.
File types. Scans, photos, screenshots and Office files should all work, not only clean PDFs.

How NEXO Chat works

It reads the documents you scan, import or connect from folders you choose, and answers in plain words.
Every answer taken from your documents shows its source and page. Tap a source to open that page, or tap "Show me where" to see the exact passage.
Answers come only from your documents. If NEXO can't find something, it says so instead of guessing.
You can ask about one file or your whole library. A chat opened from a file is about that file only.
It suggests questions based on what your documents actually contain.
It reads scans, photos of documents, screenshots, PDFs and Word, Excel and PowerPoint files.
It runs on your phone. Your documents and your questions are not uploaded, and it keeps working in airplane mode.

Tips and limits

Clear, well-lit text works best. A photo with no readable text has nothing to ask about.
For important amounts and dates, tap the source and double-check.
If you get no answer, ask for one fact at a time or open the chat from that document.
After you connect a folder, wait until "Preparing your documents" finishes.
On the free plan NEXO Chat has a daily limit (5 questions); NEXO Pro removes it. See pricing.

NEXO Chat is part of the Android app. An iPhone version is coming soon and is not yet released.
