Choose by the result you need
| Your task | Starting option | Important limit |
|---|---|---|
| Summary, then a few questions | @vustSummaryBot | Text-based PDFs. Its question flow allows up to 3 paid questions within 30 minutes of delivery. |
| Structured document analysis | @vustbot | A separate documented workflow: one document, up to 50 pages. No clickable paragraph citations. |
| Read a scan or photographed page | @image_to_text_free_bot | Extract the text first. Its operator counts each PDF page as a credit. |
VUST documents the Summary bot’s question flow separately from document analysis. The limits above belong to those specific workflows. Check the price shown in the bot; a free summary does not establish that follow-up questions are free. These published features were checked October 22; answer quality and account allowances have not been tested here.
If your PDF is a scan
Try selecting and copying a sentence. Check that the copied words make sense, including numbers and column order. If the text is missing or scrambled, use OCR before asking for a summary.
The Image to Text operator advertises five free images per month and charges a credit per PDF page. A supported long file is not necessarily a free file. Follow the image-to-text guide for a small practice image and the page-cost distinction.
Try a file whose answers you can check
Our original two-page workshop notice includes a registration exception on page 1 and an unannounced room on page 2. Use it to see whether an answer keeps the exception and admits the missing room number.

This exercise is a checking method, not a ranking of the bots. For your own document, ask about one fact near the end as well as one at the beginning. A successful upload does not establish that every page was included.
