What does Velin do?

Velin is a fact-based intelligence tool that lets you upload documents and ask questions in plain English. It uses retrieval-augmented generation (RAG) to search across your entire library and pull the exact facts you need. Instead of guessing or making things up, the AI responds with answers anchored to your sources — complete with citations back to the original files. You can upload PDFs, Excel sheets, CSVs, images, and even videos (on higher-tier plans). The system handles massive documents: 1000-page manuals, million-row spreadsheets, or batch uploads without breaking a sweat.

What makes Velin stand out is its emphasis on trust and transparency. The interface shows you retrieval match coordinates, cosine similarity scores, and exactly which module retrieved each fact. You don't just get an answer — you see why the AI thinks it's correct. Features like "Vision" let the AI read charts and images inside your documents. Web search grounding adds external context when needed. And the whole system is designed to fight hallucinations by keeping every answer tied to a specific source.

Velin works well for researchers, analysts, students, and anyone who regularly digs through piles of documents. Instead of skimming hundreds of pages to find one data point, you ask a question and get a direct answer with a link to the source. It's also useful for financial report analysis, academic literature reviews, legal document queries, or product manual troubleshooting. The plans are straightforward: a Starter tier for lighter use, an Unlimited tier for heavy research, and an Unlimited Plus plan that adds video processing.
