About Denser Retriever
Denser transforms your website, PDFs, docs, and help center into an AI chatbot that answers questions with every reply cited to its exact source. No code required, and you can have a live bot in about five minutes. It's built on Denser Retriever, an open-source retrieval-augmented generation (RAG) engine that grounds responses in your own data, keeping answers accurate and verifiable. Denser is used by over 2,000 businesses, including city governments and global enterprises, and is suited for customer support, lead generation, and internal knowledge management teams that need trustworthy AI responses without engineering overhead. Denser offers two chatbot types: a Website Chatbot that crawls your site for visitor-facing support, and a Knowledge Base Chatbot that ingests PDFs, docs, and Google Drive files for internal teams. Both rely on the same open-source retriever backend. You can embed the chatbot via a no-code widget, script, iFrame, or React component. The system continuously trains on your content, surfaces conflicting facts with contradiction detection, and provides tap-to-verify citations so users can check the source themselves. Beyond citations, Denser includes lead capture forms with CRM-ready exports, an analytics dashboard tracking queries, latency, satisfaction, and topics, plus custom actions like Calendly and Zendesk integrations. It deploys across multiple channels—web widget, Shopify, Slack, WhatsApp, Telegram—and offers a REST API for custom integrations. Pricing scales from a free tier to enterprise plans with private LLM deployment as an add-on, making it accessible for small teams and large organizations alike. Compared to opaque chatbot solutions like Zendesk or Intercom, Denser's open-source RAG engine and source transparency are genuine differentiators. It balances simplicity for non-technical users with extensibility for developers, all while keeping verifiability at the forefront.
Behind the Verdict
We'd reach for Denser when the whole point of the bot is verifiable answers. Few no-code chatbots let you click through to the exact passage behind every reply. That's a huge deal for customer support and internal knowledge bases where accuracy matters more than flash. Where it bites: the free tier is tiny — 20 queries a month and only 100 pages per bot. That's fine for testing, but you'll outgrow it fast. The jump to $39/mo buys you 1,500 queries, which is more realistic. If you need heavy traffic, Standard at $119/mo gets 7,500 queries and 2,000 pages per bot. Compared to Chatbase, Denser leads on cited answers and handling up to 100,000-page chatbots, per recent comparisons. But Chatbase might be simpler if you only need a basic FAQ bot. Denser's contradiction detection is a differentiator, but it's not a search engine — it's a chatbot. Don't expect it to replace a site search tool. Private LLM deployment costs extra on Enterprise, so if that's a hard requirement, factor in the add-on. The no-code limits mean deep custom tweaks need coding; developers will use the REST API instead. For most teams, the deployment options — web widget, Shopify, Slack, WhatsApp, Telegram — cover where customers actually ask. In practice, the 5-minute setup claim holds for a basic site crawl. The analytics dashboard is useful for tracking satisfaction and topics, and lead capture with CRM exports helps marketing. If you want a bot that feels like a support agent and can prove where it got its answer, Denser delivers.
