The AI assistant built into your knowledge base
Calli reads every article in your knowledge base and answers customer questions in plain language. No training required, no separate tool to install.
How Calli works in three steps
Calli is an AI knowledge base assistant that sits inside your help center and responds to customer questions in real time. It works in three clear steps, and the entire process takes less than five seconds.Step 1: The customer asks a question. Instead of scrolling through categories or guessing at search keywords, your customer types a natural-language question into the Calli chat window. They can ask anything, from "How do I reset my password?" to "What file formats does your import tool accept?" The question can be phrased however they like. There is no need to match exact article titles or use specific terminology.Step 2: Calli finds the answer. Calli searches your entire knowledge base using retrieval-augmented generation (RAG). It identifies the most relevant articles, pulls the key information, and writes a clear, concise answer in plain language. Every response includes a link to the source article so the customer can read the full documentation if they want more detail. Because Calli only draws from your published content, it never invents information or guesses at answers it does not have.Step 3: Escalation when needed. If Calli cannot find a confident answer in your knowledge base, it does not try to bluff. Instead, it tells the customer that it could not find a match and offers a direct link to your contact inbox. This means every question either gets answered or gets routed to a real person. No dead ends, no frustration.
What Calli is not
Most AI chatbots are trained on generic data and will happily make up answers when they do not know something. Calli is different. It is not a general-purpose chatbot. It does not browse the internet. It does not pull from a giant language model's training data to fill in gaps. Calli only answers from the articles you have written and published in your Helpable knowledge base. This is a deliberate design choice. An artificial intelligence knowledge base assistant is only useful if customers can trust the answers it gives. When a chatbot hallucinates a return policy that does not exist, or invents a feature your product does not have, it creates more support work than it saves. Calli avoids this entirely by restricting its answers to your verified content. If your knowledge base does not contain an article that addresses a customer's question, Calli will say so honestly. It will tell the customer it does not have enough information and suggest they contact your support team instead. This honesty is what makes Calli a reliable part of your support workflow rather than a liability. You can think of Calli as an assistant that has memorized your entire help center and can explain any article in conversational language. Nothing more, nothing less.
Why Calli is different from search
Traditional help center search depends on keyword matching. If your customer types "change email" but your article is titled "Update account settings," the search might miss it entirely. Customers have to guess the right words, try multiple searches, and then read through full articles to find the specific paragraph that answers their question. Calli understands intent, not just keywords. When a customer asks "How do I change my email address?" Calli knows they are asking about account settings even if those exact words never appear in the article title. It reads the content of every article, understands what each one covers, and matches the customer's question to the right information. The difference matters most for complex questions. Suppose a customer asks, "Can I add my colleague to my account without giving them billing access?" A keyword search would struggle with that query. Calli can locate your article about team roles, find the section about permission levels, and explain exactly how to add a team member with limited access. It synthesizes information from your articles into a direct answer. Your help center still has full-text search for customers who prefer browsing. Calli is an additional layer that handles the questions traditional search cannot. Both tools are available on every plan that includes Calli, and they work side by side inside the embeddable help widget as well as on your standalone help center.
AI knowledge base features
Natural language answers
Calli reads your questions like a person would and responds with clear, direct answers instead of a list of links. Customers get the information they need without scanning through articles.
Source citations on every answer
Every response from Calli includes a link to the source article. Customers can verify the information or read the full article for additional context whenever they want.
Multi-turn conversations
Customers can ask follow-up questions in the same conversation. Calli remembers the context of previous messages, so customers do not have to repeat themselves.
Automatic knowledge updates
When you publish or update an article, Calli picks up the changes automatically. There is no retraining step, no delay. Your AI assistant always reflects your latest documentation.
Honest "I don't know" responses
When Calli cannot find a relevant article, it tells the customer clearly and offers to connect them with your support team through your contact form. No fabricated answers.
Works with the AI article writer
Use the AI article writer to create documentation quickly, then let Calli answer questions about it. The two features complement each other.
Custom Context for Enterprise: train Calli on your documents
On the Enterprise plan, Calli goes beyond your published help center articles. You can upload PDF manuals, internal documentation, product specifications, and other reference materials as additional context sources. Calli uses retrieval-augmented generation (RAG) to search these documents alongside your articles when answering questions. This is especially useful for companies with extensive technical documentation that lives outside the help center. Instead of copying hundreds of pages from a product manual into individual articles, you upload the PDF directly. Calli indexes the content and references it when a customer asks a relevant question. The original formatting, diagrams, and structure of your documents are preserved. Custom Context sources are managed from your Helpable dashboard. You can upload new documents, remove outdated ones, and see which sources Calli references most often. Each Enterprise account supports up to 500 MB of uploaded documents, with higher limits available on request. This knowledge management software feature is designed for organizations that need their AI assistant to cover more ground than a standard help center. If your support team regularly answers questions by referencing product manuals or technical specifications, Custom Context lets Calli handle those questions directly.
Your knowledge base answers questions beyond your own site
Helpable automatically generates structured data (FAQPage, HowTo, Article schema) for every article you publish. This means your knowledge base content can surface as direct answers in ChatGPT, Perplexity, and Google AI Overviews. When a customer types "how do I reset my password at [your company]" into an AI assistant, the answer can come straight from your published articles. Ticket deflection happens on two levels: customers who visit your help center find the answer themselves, and customers who ask AI search engines get the answer without visiting your site at all. No extra configuration needed. Learn more about SEO and AI visibility.

Frequently asked questions
How does Calli avoid making up answers?
Calli uses retrieval-augmented generation, which means it only generates answers based on the content it retrieves from your published articles and uploaded documents. It does not draw from general training data or external sources. If Calli cannot find relevant content in your knowledge base to answer a question, it will tell the customer that it does not have enough information and suggest they contact your support team directly. This design prevents the hallucination problem that affects general-purpose AI chatbots.
Does Calli work in the embeddable widget or only on the help center?
Calli works in both places. It is available on your standalone help center page and also inside the embeddable help widget that you install in your product. When a customer opens the widget and switches to the AI tab, they get the same Calli experience as they would on your public help center. This means your customers can ask Calli questions directly from within your product without navigating to a separate site. The widget and Calli share the same knowledge base and the same answer quota.
What happens when I run out of Calli answers for the month?
When your monthly Calli answer quota is reached, the AI chat interface is temporarily disabled until your quota resets at the start of the next billing cycle. Your help center and all of your articles remain fully accessible. Customers can still search, browse categories, and submit contact forms. Only the AI-generated answers are paused. If you frequently hit your limit, you can upgrade to a higher plan at any time from your dashboard, and the new quota takes effect immediately.
Do I need to train or configure Calli before it works?
No. Calli works automatically as soon as you have published articles in your knowledge base. There is no training step, no configuration wizard, and no integration setup. Calli reads your articles in real time, so any article you publish or update is immediately available for Calli to reference. If you are on the Enterprise plan and want to add Custom Context sources like PDF manuals, you upload them through your dashboard and Calli indexes them within a few minutes.
Can Calli answer questions in languages other than English?
Calli responds in the same language the customer uses to ask the question. If your knowledge base articles are written in English but a customer asks a question in Spanish, Calli will attempt to find the relevant English article and provide its answer in Spanish. The accuracy of cross-language answers depends on the complexity of the content and how well the underlying AI model handles that specific language. For the best results, we recommend writing articles in the languages your customers use most frequently.
How is Calli different from adding a chatbot to my help center?
Traditional chatbots typically rely on decision trees, pre-written scripts, or general AI models trained on broad internet data. They require manual configuration of conversation flows, and they often give irrelevant or fabricated answers when a question falls outside their scripts. Calli is different because it is grounded entirely in your knowledge base content. It does not follow scripts. It reads your actual articles and generates answers from that specific content. There are no conversation flows to design, no intents to map, and no training data to provide. You write articles, and Calli answers questions about them.
