Conversion, OCR or a document answer?
These are different jobs. Choose the result before uploading a file.
- Change the file format: ONLYOFFICE documents office-file conversion in a private bot chat. Group behavior is different.
- Get text from a scan: Image to Text is linked by its maker for OCR. Check a small result against the original.
- Ask about the document: use the source-backed question workflow below, and ask for the passage that supports the answer.
These two additional bot profiles are based on public operator documentation. No file conversion or OCR result was tested in them for this page.

| 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.

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.
