Questions
An AI chatbot builder is a tool for creating a chatbot that answers from your own content. Most use forms or a drag-and-drop flow editor. Denser's builder also has Ask AI, an assistant that builds and changes the chatbot for you when you describe what you want in plain language.
No. You describe what you want and apply the changes Ask AI proposes. Connecting your own API takes a URL or a request copied from the API's docs, and adding the chatbot to your site is one embed snippet or the WordPress plugin.
No. Ask AI can read your workspace, but every change it suggests is a card you apply, edit, or dismiss. It deletes things only when you ask it to, and a card goes out of date instead of overwriting something that changed after it was proposed.
No. Keys, tokens and passwords go into a secure card that sends them straight to Denser, and Ask AI never sees them. Saved keys are stored encrypted and never shown again.
Yes. Ask it to audit the chatbot or to find questions it answered badly. It checks sources, crawl failures, passage quality, contradictions and settings, reads the answers your customers flagged, and reports each problem with a link to fix it. It can ask your chatbot a question the way a visitor would, and proposes the fix when you ask for one.
Ask AI is included on every plan, including Free. Each message to Ask AI uses one query from your plan, the same as one chatbot answer, and each test question it asks your chatbot uses one more.
For customer support, yes. Besides answering from your content, the agent can run actions such as booking meetings, calling your API or handing off to a person, show cards, and follow playbooks, and Ask AI can build each of those from a sentence.
Point Denser at your website, docs, and PDFs. It answers in minutes, every reply cited to its exact source.
