Valk WeldingAI knowledge base
A knowledge base chatbot is an AI assistant that answers from the information your organization provides, not from guesswork. It finds the most relevant passages across your files and websites, writes a clear response, and cites the source so people can verify it.
Instead of searching folders, scanning long documents, or asking a coworker the same question again, employees and customers can ask in natural language and get an answer grounded in your current knowledge.
How it works

Upload PDF, DOCX, TXT, Excel, and PowerPoint files, connect Google Drive, crawl a website, or write Q&A directly. Denser Chat indexes the content so it is ready to answer questions.

Alex's Workspace
Workspaces & teams
Create your knowledge base chatbot in a shared workspace and invite your team. Everyone searches the same up-to-date knowledge, so you maintain sources in one place instead of one bot per person.
Denser cut our research time from about 50 minutes to just a few, a huge boost to our team's productivity.
Questions
Websites, PDFs, DOCX and other Word files, PowerPoint presentations, TXT files, Excel spreadsheets, Google Drive, and written Q&A. Combine as many sources as you need into one searchable knowledge base.
Denser uses retrieval-augmented generation (RAG): it finds the exact passage in your own content first, then answers from it and links the citation. If the answer is not in your sources, it says so instead of guessing.
A single Denser chatbot indexes hundreds of thousands of pages and up to 50GB of documents, with three-layer retrieval (keyword, vector, and ML reranking) that stays accurate at that scale.
Yes. Build a chatbot once in a shared workspace and invite your team with owner, editor, and viewer roles. Everyone searches the same up-to-date knowledge, with one place to manage sources and access.
A one-click read-through of everything your chatbot knows. You get a plain-English summary of the topics it covers and a list of any contradictions between documents, so you can fix conflicts before your users hit them.
Denser is SOC2 Type II certified. Data is encrypted in transit and at rest, your content is never used to train shared or foundation AI models, and access controls let you restrict sensitive sources.
