An AI chatbot trained on your data

Turn your website, docs, and PDFs into a chatbot that answers visitor questions in your own words, with a link to the source.

Your visitors are asking questions your website already answers. The problem is finding those answers: scrolling through a long FAQ page, navigating a help center, or giving up and sending an email. An AI chatbot trained on your data removes that gap. It reads your website, your documents, and your files, and answers visitor questions in your own words, with a link to the source.

This is not a general-purpose AI assistant. It does not draw on public internet knowledge. It is an AI chatbot trained on your data, and only your data.

How training on your data works

Knowster reads the content you point it at, builds a search index from that material, and uses that index to answer visitor questions. When someone asks a question, the system finds the passage that best matches the query, forms a response from that passage, and cites the source so the visitor can read the original.

If the answer is not in your training data, the chatbot says so rather than guessing, and offers to connect the visitor with your team.

For a full step by step walkthrough, see the guide to training an AI chatbot on your own data.

What you can train the chatbot on

Training data comes from three sources. You can use any combination.

Your website. Paste any URL you own and Knowster crawls the page and linked pages under the same domain. You can train on a full site, a specific section such as your help center, or individual pages. The chatbot re-syncs automatically when your content changes. Supported: public HTML pages. Pages behind a login are not crawled.

Your documents. Upload files directly from the dashboard. Knowster extracts the text, indexes it, and makes it queryable within minutes. Supported: PDF, DOCX, TXT.

Pasted text. Copy and paste any text directly into the training panel. Useful for FAQ content you maintain in a spreadsheet, policy summaries that change often, or product details that do not have a public URL.

A typical setup combines all three: a website URL for main product and help content, a few PDFs for detailed technical specifications, and pasted text for policies or announcements updated on short notice.

Answers from your content, not guesses

Generic AI tools answer from broad public knowledge. They know what the internet says about your general category, not what your specific product does, what your return policy says, or what changed in your last release.

When the chatbot is trained on your data, every answer comes from a source you control. The chatbot cites that source on each reply. If an answer is wrong, you trace it to the source, update the content, re-sync, and the chatbot corrects itself. There is no opaque retraining step required.

Knowster vs a generic chatbot

How training your data compares to ChatGPT and generic RAG chatbots

Teams exploring AI chatbots often start by testing a general-purpose AI assistant with a custom system prompt, or by evaluating a scripted chatbot builder that maps every response path by hand.

A prompted general AI session has no specific knowledge of your content. It approximates your product based on what it has seen publicly. When your product differs from the category average, it gives visitors confident but wrong answers.

A scripted chatbot builder requires maintaining every response manually. When your product changes, you rewrite responses. When new questions arrive, you add new branches. The maintenance burden scales with the product, not with the team.

A system trained directly on your documents sits between these two approaches. It answers from your specific content, updates when that content changes, and does not require scripting responses one by one. The limitation: it only knows what is in the training data, and answers are only as accurate and complete as the source material.

What you get

• A chatbot that answers from your own website and documents.
• Auto re-sync when connected source content changes.
• Source citation on every answer.
• Human handoff when the chatbot cannot answer or the visitor requests it.
• A widget that embeds on any website with one script tag.
• An analytics view showing what visitors asked and where the chatbot answered or handed off.

Set it up in minutes

1. Add a content source: paste your website URL, upload a document, or paste text directly.
2. Wait for training. Most runs complete in under two minutes.
3. Test with real questions. Use the preview panel to ask what your visitors actually send.
4. Embed the widget. Copy one script tag and paste it into your site.

FAQ

How does Knowster train a chatbot on my data?

Knowster reads your website pages, uploaded documents, and pasted text, then builds a search index from that content. When a visitor asks a question, the chatbot finds the most relevant passage and uses it to write the answer, with a link to the source.

What kinds of documents can I use?

You can use URLs you own, PDFs, Word documents, plain text files, and pasted text. Most teams start with their help center, product pages, and existing FAQ content.

Do I need to code anything?

No. You paste a URL or upload a file, click train, and the chatbot is ready. The embed code is one script tag.

How long does it take to train?

Most training runs complete in under two minutes for a typical website or document set. Larger libraries take longer but run in the background.

Can I train a chatbot on my own data?

Yes. Knowster is built specifically to train a chatbot on your own website, documents, and files. It learns from your content, not from general internet data.

What is the difference between training a chatbot on my data and using ChatGPT?

ChatGPT answers from public internet knowledge. A chatbot trained on your data answers only from your specific content, so it knows your product, your policies, and your exact wording rather than working from general assumptions.

How do you train a chatbot on custom data step by step?

Add a content source (a URL, file, or pasted text), wait for training to complete, test with real questions in the preview panel, then embed the widget on your website. The companion longread walks through each step in detail.

What is chatbot training data, and what makes good training data?

Training data is the text the chatbot learns from. Good training data: product documentation, help articles, FAQ pages, policy documents. Poor training data: internal notes, marketing decks, out of date content not written to answer customer questions directly.

Can I train an AI chatbot on a PDF or Word document?

Yes. Upload a PDF, DOCX, or TXT file from the dashboard. Knowster extracts the text, indexes it, and makes it available to the chatbot within minutes.

Does the chatbot re-train automatically when my website changes?

Yes. Knowster monitors connected URLs and re-indexes them when content changes. You can also trigger a manual re-sync at any time from the dashboard.

Is my data private if I train a chatbot on it?

Your content is stored in your Knowster account and is not shared with other users or used to train any shared model. Your training data stays in your account.

Can I try Knowster free before I train it on my data?

Yes. The free plan lets you connect your first content source and test the chatbot without a credit card.

Keeping it current

Training data goes stale when products change, policies update, or new content replaces old. Knowster monitors connected URLs and re-indexes them automatically when changes are detected. For uploaded documents and pasted text, you re-upload or re-paste from the dashboard at any time, and the chatbot updates within minutes.

If a sync fails, such as when a source URL becomes unreachable, you receive a notification before outdated answers reach visitors.
