Key Features of Denser AI
Denser AI features have been designed to balance ease of use for non-technical users and customization power for developers.
1. Data Ingestion and Knowledge Base
Creating a chatbot in Denser requires you to first build its knowledge base. Unlike many chatbot platforms that only accept plain text FAQs, Denser needs a wide range of inputs. You need to input your websites, PDFs, Word documents, PowerPoint slides, Excel spreadsheets, text files and as many as you can. You can point the system at a single URL, upload multiple files, or crawl an entire site with thousands of pages. Just ensure a single hair from your company data isn’t laying down.
If your organization uses cloud storage, Denser integrates with Google Drive. This will help your chatbot to connect directly to folders and automatically pick up new or updated files. So you don’t need to be uploading manually.
On Denser Standard plans and above, you can set your bot to refresh its knowledge base daily, weekly, or monthly using auto-rebuild scheduling. That means if your website content changes or new documents are added, Denser will automatically re-ingest them.
2. Verifiable Answers with Citations
It’s funny how traditional chatbots often hallucinate. They confidently answer incorrectly, failing to show where the information came from. Denser solves this problem with verifiable answers. Every response comes with a citation, highlighting the exact passage from your source material. Your website visitors can expand these citations to view the context inside the original PDF, web page, or document.
This feature will build trust and compliance especially in industries like finance, law, or healthcare.
3. Integrations and Channels
Once you’ve built your chatbot, you can embed it directly on your website with a widget or iframe. Remember to catch fun while customizing the widget button color, shape, placement of chatbot’s greeting message via the dashboard.
Denser allows employees to query company documentation without leaving their workspace by integrating it with Slack. Teams can ask questions in Slack, and Denser responds by pulling the most relevant passages from shared files or intranet pages.
Integrating Denser with Zapier will also open connections to thousands of other apps like CRMs, helpdesks, project management tools, and more. It also natively integrates with Google Sheets, so lead data collected by the chatbot can flow directly into a sheet for easy tracking.
4. Models and Control
Through Denser API or dashboard, you can select from different models such as gpt-3.5 (fast and cost-effective), gpt-4 and gpt-4o (balanced quality and reasoning), claude-3-5-sonnet and claude-3-5-haiku (Anthropic’s lightweight and high-performing models), claude-3-7-sonnet (newer, faster, more accurate option).
5. API and Developer Tooling
You can skip this part, it’s only for technical teams. Denser allows developers to send a POST request with parameters such as chatbotId, question, optional context, chosen model and citation (true/false).
The API then returns a JSON response with the answer text plus passages containing citations and sources. This design makes it easy to integrate Denser into custom dashboards, mobile apps, or enterprise platforms.
6. Chatbot Customization, Actions and Lead Capture
Denser lets you customize the chatbot’s name, icon, greeting message, and default suggested questions. This makes the bot feel on-brand and approachable for your users. You can also command it to trigger custom buttons or links for certain queries.
When you collect names, emails, phone numbers, or custom data points, the inbuilt lead capture will route them to Google Sheets or connected apps. This turns the chatbot into a sales funnel, not just a support tool.
7. Analytics, Logs and Auto-Rebuild
Denser’s logging and analytics features provide visibility into how users interact with your bot. Depending on your plan, conversation logs are retained for 30 days (Starter), 90 days (Standard), or up to 360 days (Business). This history is needed for understanding which questions users ask most frequently, where the bot performs well, and where gaps exist.
You can even use this data to improve documentation, refine the chatbot’s responses, or decide when to add new content sources. Combined with auto-rebuild scheduling, you can keep your bot’s knowledge base fresh while continuously optimizing performance.
8. Access Control and Security
If you just create your bot, it’s private by default and accessible only to authenticated users. To make it public, you need to explicitly change its access settings. This means you can safely test bots internally before exposing them externally.
For developers, API access is secured through generated keys. In higher tiers, team management features allow admins to assign access levels. Enterprise plans also include advanced security features and compliance support for regulated industries.
DenserRetriever: For Technical Buyers
DenserRetriever is a retrieval engine optimized for connecting large language models (LLMs) with structured and unstructured data sources. You can deploy it in your own environment (via Docker) and query it through an API.
DenserRetriever works by taking in your data (documents, text chunks, or indexed webpages), then performing a multi-stage retrieval pipeline which are keyword search, vector search and re ranking with ML.
This layered approach ensures that whether a user searches for an exact phrase, a paraphrased question, or a concept, the system consistently retrieves the most relevant passages.
Denser Setup: From Zero to Live in 10 Minutes
You can create, customize, and launch a fully functional AI assistant in under 10 minutes with four straightforward steps.
Step 1: Create a Bot and Add Content
To create a new chatbot, login to your Denser account. The system immediately prompts you to add data sources that will form your knowledge base. You can upload files such as PDFs, Word docs, Excel sheets, PowerPoint presentations, or text files. You can also enter a URL for Denser to crawl, which can be a single page or an entire website with thousands of pages. It’s advisable to connect Google Drive to sync files directly from cloud storage. This won’t take more than a minute.
Step 2: Configure Prompt, Model & Citations
Next, you’ll configure how your bot responds. Use the system prompt to set a short instruction that guides the tone and style of the chatbot. You’ll also select which LLM you want to power your chatbot such as GPT-4o, GPT-3.5, Claude 3.5 Sonnet/Haiku, or Claude 3.7 Sonnet. Then enable or disable citations.
Step 3: Customize the Widget and Deploy
Once the bot’s behavior is configured, you can make it match your brand. In the Customization tab, you can edit your chatbot name, avatar, and greeting message, suggest starter questions for new users and edit the widget button color, size, and placement on your website.
The deployment process is simple. There’s a code snippet (JavaScript iframe) that will be generated, copy and paste it into your website’s HTML to bring your chatbot to live.
Step 4: Enable Lead Capture & Monitor Logs
The final step is turning your chatbot from a passive responder into a lead-generating tool. Inside the dashboard, you can enable lead capture forms, prompting users for details like name, email, or phone number.
From here, you can export leads to Google Sheets, sync them via Zapier into your CRM, or manage them directly in Denser’s dashboard.
At the same time, the Logs section lets you review every conversation. This makes it easy to spot what users ask most frequently, identify gaps in your documentation, and continuously optimize your chatbot’s performance.

Denser AI vs Alternatives
The AI chatbot market is already crowded. Let’s quickly compare it against other players.
Denser AI vs Chatbase
Chatbase is also a very popular no-code chatbot builder. Both Denser and Chatbase allow you to upload documents or connect data sources to power a conversational assistant but there’s something missing.
Denser always grounds answers in verifiable sources, while Chatbase responses tend to be “black box,” with less transparency into where the information came from.
Second, Denser has an open-source retriever (DenserRetriever) available on GitHub, Chatbase retriever is a closed, proprietary system.
Denser AI vs Botpress
Botpress is very powerful but requires more time and technical know-how to deploy.Denser, in contrast, is about speed and simplicity.
If you need deep agent capabilities (complex conditional flows, transactional bots, or advanced logic), Botpress may be the better fit. Otherwise, if simplicity and reliable knowledge chatbot with RAG-backed accuracy, is what you need, Denser is faster to set up and easier to maintain.
Implementation Tips & Best Practices to Denser AI
Here are some best practices I promised to share in order to help your businesses get the most from their deployment.
1. Consolidate documents into a smaller number of organized files rather than hundreds of scattered PDFs or slides.
2. Use clean headings and structure in your documents.
3. Ensure PDFs are searchable text, not just scanned images. If your documents are scanned, run them through OCR (optical character recognition) before uploading.
4. Use GPT-4o for high-quality, nuanced answers where tone and reasoning matter.
5. Use Claude 3.5 Sonnet/Haiku for strong summarization, lightweight Q&A, and faster responses at scale.
6. Use Claude 3.7 Sonnet for newer variant balancing speed with improved reasoning.
7. Limit who can edit chatbots or view leads.
Final Verdict
Denser AI has quickly emerged as one of the most balanced retrieval-augmented chatbot platforms in the market. Non-technical users enjoy its simplicity while developers enjoy the depth and transparency they need.
You should buy Denser AI if you run SMBs and mid-market companies that want a no-code. Also, as an enterprise that values verifiable AI answers you can consider it. Plus, marketing and sales teams can optimize it to add lead-generation chatbots to websites.
