You stay in charge

It proposes. You apply.

  • Every change is a card: apply it, edit it, or dismiss it.
  • Applied changes run with your permissions, nothing more.
  • API keys and passwords go straight to Denser. Ask AI never sees them.

Audit

Find problems before customers do.

Ask “Audit my chatbot.” It checks:

  • Sources that failed or went stale
  • Pages that are mostly navigation or boilerplate
  • Content that contradicts itself
  • Missing instructions, starters or citations
  • Answers your customers flagged
Ask AI's audit report for a chatbot: instructions that conflict with the chatbot's own sources, and passages that are mostly navigation and marketing copy, each with a link to where to fix it.
Each problem comes with a link to fix it.

Questions

What is an AI chatbot builder?+

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.

Do I need to write code?+

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.

Can Ask AI change my chatbot without asking?+

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 It deletes things only when you ask it to, and a card goes out of date instead of overwriting something that changed after it was proposed.

Does Ask AI see my API keys or passwords?+

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.

Can Ask AI check my chatbot's answers?+

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.

How much does Ask AI cost?+

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.

Is Denser a no-code AI agent builder?+

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.
