Building your own personal chatbot can seem like a daunting task, but with the right tools and knowledge, it’s not as complicated as you might think. In this blog post, we’ll be discussing the steps involved in building a chatbot on any topic of your choosing, as the archived Tom Brady chatbot example shows. For a practical next step, see our create a custom chat.
What Is a Personal Chatbot?
A personal chatbot is a source-grounded AI assistant trained on a focused set of documents, webpages, or files chosen by an individual. Instead of answering from the open web alone, it retrieves relevant passages from the approved source set and uses them to answer questions about one topic, project, person, or knowledge base.
| Type | Best For | Knowledge Source |
|---|---|---|
| Generic chatbot | General Q&A | Model training data |
| Personal chatbot | One person, topic, or project | Approved URLs, files, notes, or documents |
| Business knowledge chatbot | Team or customer support | Company docs, help center, policies, or uploaded sources |
If you are building from your own material, start with a narrow approved source set and expand only after testing shows where users need more coverage.
Why Build Your Own Personal Chatbot On A Topic?
Building your own chatbot on a specific topic has many benefits. For starters, it allows you to dive deep into a subject that interests you and gain a deeper understanding of it. This can be especially useful if you’re looking to become an expert in a particular field or learn more about a particular person or brand. Instead of manually opening every relevant page, you can focus on a curated source set and ask questions against it.
Moreover, building a chatbot on a topic also allows you to engage with others who share your interests. By building a chatbot, you’ll be able to connect with like-minded individuals and share your knowledge and insights. This can lead to new friendships and opportunities for collaboration. Imagine building a chatbot on your favorite topic and then sharing it with friends to enjoy or research.
If your goal is to make the chatbot represent your own expertise, follow this guide to create a ChatGPT clone of yourself with CustomGPT.ai.
Additionally, building a chatbot can also be a great learning opportunity. You’ll have the chance to work with new technologies and tools and learn how to use them effectively. This can be especially beneficial for those looking to develop their technical skills or for students/researchers looking to deep dive into a particular field or topic.
Here are some of the main benefits of building your own sitemap and chatbot:
Conduct Research on a Topic
By creating a custom sitemap and chatbot, you can conduct research on a particular topic or industry. For example, if you are interested in learning more about a specific industry or market, you can use a tool like ahrefs to collect a list of relevant web pages and create a custom sitemap.
You can then use a generative AI chatbot like CustomGPT.ai to analyze the content of these web pages and provide insights and predictions about the market. This can help you make more informed decisions about your business or investments.
For example, here is a CustomGPT.ai chatbot built on the topic of “Abraham Lincoln”. It was built from a focused collection of Lincoln webpages.
When asked the question “How was Lincoln’s relationship with his son?”, the bot responded with:
The available evidence indicates that Abraham Lincoln had a close and respectful relationship with his son. Biographer Jason Emerson wrote that Robert was "intelligent, witty, kind, gentlemanly, proper, and generous," and that Abraham showed his gratitude to his stepmother by being "like an own son to her." Furthermore, the soldiers remarked on the "complete and sacred" understanding between the man and the boy when they marched hand in hand through the streets of Richmond.
To build a ChatGPT-style chatbot like this:
- Use this free tool and give it a list of keywords.
- Input the generated sitemap into CustomGPT.ai.
- After the import finishes, start asking questions.
Gather Competitor Intelligence
Creating a custom sitemap and chatbot can also help you gather intelligence about your competitors. By collecting a list of web pages from your competitors’ websites, you can use a generative AI chatbot to analyze their content and provide insights about their strategies, products, and marketing. This can help you identify areas where you can improve and stay ahead of the competition.
Use this carefully: with an approved list of public competitor pages, you can study positioning patterns and generate ideas for your own content plan. Keep the output original and review it before publishing.
Learn from Your Private Data
Creating a custom sitemap and chatbot can also be used to learn from your own private data. For example, if you have a large knowledgebase or repository of documents, you can use a generative AI chatbot to analyze the content and provide insights and recommendations based on the data.
Update: You can now also upload your documents and build a chatbot from approved files. No more manually searching through PDF documents to get the answers you want.
This can help you identify patterns and trends that may not be apparent by manual analysis.
You can do this with a security and compliance-focused no-code cloud-hosted platform like CustomGPT.ai.
Automate Customer Support and Engagement
Finally, creating a custom sitemap and chatbot can also be used to automate customer support and engagement. By using a generative AI chatbot, you can provide instant and personalized responses to customer inquiries and support tickets. This can help reduce response times and improve customer satisfaction.
Overall, creating a custom sitemap and chatbot can provide many benefits for businesses and individuals, reflecting the broader benefits of building your own chatbot. With CustomGPT.ai, you can question approved sources, surface useful patterns, and make better decisions from one focused knowledge base.
How Does This Work?
A CustomGPT.ai chatbot retrieves the most relevant passages from the URLs and files you approve, then uses the selected model to draft an answer from those sources.
When you ask a question, the chatbot searches your approved source collection first: webpages, files, sitemaps, or other connected content. That grounding helps keep answers tied to the material you selected.
The answer is only as strong as the source material behind it, so start with focused, trustworthy content and test the chatbot with real questions before sharing it.
Better source coverage usually means better answers, but relevance matters more than volume.

Step-by-Step Guide
Here is the setup flow.
Step 1: Choose Your Topic
The first step in building your own chatbot is to choose a topic. This can be anything you’re passionate about or knowledgeable about. It can be a celebrity, a sports team, a historical figure, a specific brand or keyphrase. Once you’ve chosen your topic, you’ll need to gather information about it. This information will form the basis of your chatbot’s knowledge base.
UPDATE: If you are unsure about how to build your collection, see this library of free tools we have built to help you create your collection of knowledge bases.
For example, let’s say your topic is “Tom Brady”
Step 2: Collect Your URLs
Next, you’ll need to collect a list of URLs that contain information about your chosen topic. There are a few different ways to do this. One of the simplest methods is to use Google to search for relevant websites and then use Ahrefs to export the list.
To build my Tom Brady list, I simply searched Google for a bunch of Tom Brady-related keywords and then used Ahrefs to download the list.
Step 3: Create the Sitemap
Once you’ve cleaned your URLs, it’s time to create your sitemap. You can use this free online tool to create your sitemap. Use the Copy option to copy the link to the sitemap.
Build Your CustomGPT.ai Chatbot
And now, the final step: To build your personal custom ChatGPT-style chatbot based on the webpages you collected, do these simple steps:
Step 1: Setup the Project in CustomGPT.ai
Once you sign up for CustomGPT.ai, select “Create Project” and enter your validated sitemap URL into your Project.
Step 2: Enjoy!
After the import finishes, click on the “Ask Me Anything” button and start questioning your chatbot just like you would with ChatGPT.

What Webpages Can I Use?
You can use any web pages that you want. You can literally research any topic, make a collection based on that and make a chatbot from it.
Example: You can build a chatbot from your own public writing, notes, and approved source material, then use it to draft responses in a consistent voice. Review every answer before using it for email, social posts, essays, or other public content.
Can We Use Your Spreadsheet?
Absolutely. Here is my Google Sheets. Make a copy and replace the URL list.
Help – I’m Not Technical
This procedure is simple. If you are non-technical, use the CustomGPT.ai free tools library to create your sitemap, then add it to your project.
Can I build a chatbot just using keywords?
We hear you: you have a list of keywords based on your niche and want to build a chatbot from it. Use the CustomGPT.ai free tools library with your keyword list, then use the generated sitemap to build your chatbot in CustomGPT.ai.
Tip: Search for your own name with the free tools library and build a ChatGPT-style chatbot based on keywords with the public information about you.
When to Use a Personal Chatbot
Use a personal chatbot when you have a focused source set and repeat questions. It works best for studying one topic, researching a project, summarizing your own notes, drafting in a consistent voice, or helping others explore a curated knowledge base.
Do not use a personal chatbot as a general search engine or as a substitute for expert review in legal, medical, financial, or compliance-sensitive decisions. For those topics, keep answers tied to approved sources and have a qualified person review the output before acting on it.
Frequently Asked Questions
How do I make my own personal chatbot without coding?
You can build a personal chatbot without coding by choosing one topic, gathering the URLs or files you want it to use, importing them into a no-code RAG chatbot builder, and then testing it with real questions. Published examples for this use case include Tom Brady and Abraham Lincoln chatbots built from focused source collections. Start narrow, use clean source material, and expand only after testing shows gaps.
Can I train a personal chatbot on my own private data instead of public websites?
Yes. A personal chatbot can be grounded in your approved files, documents, audio, video, or URLs instead of public websites. If privacy matters, look for GDPR compliance, a stated policy that your data is not used for model training, and SOC 2 Type 2 audited security controls. Retrieval-augmented generation helps keep answers tied to your source material rather than relying only on general model knowledge.
Is it possible to build a personal chatbot as an individual, or is this only for companies?
Yes. Personal chatbots are not limited to large companies. If you are building one on your own, the simplest approach is to start with one audience, one topic, and one small set of trusted sources.
How much content do I need to build a chatbot on a specific topic?
There is no fixed minimum. For a narrow topic, a few high-quality sources can be enough to start. For broader subjects, larger collections can help; start with the most authoritative material first, then add more only when testing reveals gaps.
How accurate can a topic-specific personal chatbot be?
A topic-specific chatbot can be highly accurate when it retrieves answers from approved sources and shows citations. In practice, accuracy is strongest when your source material is current, well-structured, and directly relevant to the questions users will ask.
Can a personal chatbot help me study or research one topic faster?
Yes. A personal chatbot can speed up study and research because it lets you question a focused body of material instead of manually opening dozens of sources. That is the practical advantage: faster exploration, follow-up questions, and synthesis on one topic.
How do I test whether my personal chatbot is ready to share?
Test it with the exact questions real users are likely to ask, then check whether each answer stays on topic and cites the source it used. A practical checklist is: verify coverage for your top questions, try messy wording and edge cases, confirm citations are correct, and review conversation analytics for failure patterns.
Conclusion
A focused personal chatbot helps you question one trusted source set, find patterns faster, and reuse your expertise in answers, drafts, and research workflows.
By following the steps in this post, you can build a chatbot around one topic, test it with real questions, and improve it as your source collection grows. Ready to build from your own source material? Start a free CustomGPT.ai project.
