I Built an AI Learning Companion for People Who Want to Learn by Building

Ajay Dhangar — Fri, 02 Oct 2026 07:44:15 +0000

For the Hacktoberfest Weekend Challenge: Build for a Friend, I wanted to build something that wasn't just another AI demo.

I wanted to build something that could actually help someone learn.

So I built AIBuddies.

AIBuddies is an open-source AI learning companion that brings together learning paths, practical projects, interactive demos, and community-driven resources in one place.

The Problem

Learning AI can be overwhelming.

There are thousands of tutorials, courses, papers, GitHub repositories, tools, and frameworks.

But when someone is just starting, the difficult question is often:

"What should I learn next, and what should I build?"

I wanted to create something that makes that journey easier.

Instead of only reading theory, learners should be able to:

Learn → Build → Experiment → Understand → Share

That's the idea behind AIBuddies.

What's Inside AIBuddies?

The platform currently brings together different areas of AI learning, including:

🧠 Machine Learning fundamentals
🔥 Deep Learning with Python
👁️ Computer Vision
💬 NLP and AI applications
🛠️ Hands-on projects
🧪 Interactive AI demos
📚 Learning resources
🤝 Community-driven learning

There are also practical examples such as AI-powered chatbots, image recognition, voice assistants, text-to-speech, and style-transfer experiments.

The goal is not to make AI feel magical.

The goal is to make it understandable and buildable.

Why I Built It for a Friend

The inspiration behind this project is simple.

Imagine someone who wants to learn AI but doesn't know where to start.

They jump between YouTube, documentation, courses, GitHub repositories, and random tutorials.

After a while, they have consumed a lot of information but haven't built much.

I wanted AIBuddies to become the kind of resource I could send to that person and say:

"Start here. Pick a path. Build something. Keep going."

That's what Build for a Friend means to me.

Not necessarily building something for a person's specific job.

Sometimes it's building something that helps someone you care about become better at something they want to learn.

Why Open Source AI Matters

This project is part of CodeHarborHub, my open-source initiative focused on making technology education more accessible.

AIBuddies follows the same philosophy:

Learning should be open, practical, and community-driven.

Open-source AI makes this ecosystem even more interesting because learners can go beyond simply calling an API.

They can explore models, tools, implementations, experiments, and projects.

They can learn how things work.

They can modify them.

And eventually, they can contribute back.

That creates a much more interesting learning loop:

Learn
  ↓
Experiment
  ↓
Build
  ↓
Break Things
  ↓
Understand
  ↓
Contribute
  ↓
Help Someone Else

What I'm Exploring

While building AIBuddies, I'm also exploring how an AI education platform can evolve beyond static documentation.

Some areas I'm interested in developing further:

Interactive AI experiments
Project-based learning
AI-assisted learning experiences
Open-source model experimentation
Beginner → advanced learning paths
Community contributions
Practical AI challenges
More browser-based AI demos
Better project discovery
AI tools that help learners understand concepts

The long-term idea is bigger than a collection of tutorials.

I want AIBuddies to become a place where people learn AI by actually building AI.

Built as Open Source

AIBuddies is publicly available so developers and learners can explore the project, suggest improvements, and contribute.

GitHub: https://github.com/ajay-dhangar/ai-buddies
CodeHarborHub: https://codeharborhub.github.io/

What's Next?

This challenge is only the beginning.

I'm planning to continue improving AIBuddies with more practical learning paths, projects, experiments, and community contributions.

Because I don't think the best way to learn AI is to consume 100 tutorials.

Sometimes it's better to build one small thing, understand why it works, break it, fix it, and then build the next thing.

That's the learning experience I want AIBuddies to encourage.

Build for a Friend

For me, this challenge isn't just:

"Build something with AI."

It's:

"Build something that makes another person's journey easier."

And that's exactly what I wanted AIBuddies to be.

If you're learning AI, I'd love for you to explore it.

If you're building something similar, I'd love to see it.

And if you have an idea for how AIBuddies could help learners better, feel free to contribute or open an issue.

Let's make AI learning more open, practical, and fun.

CodeHarborHub is an open-source learning platform offering tutorials, documentation, and community-driven projects for developers.

As a maintainer, I focused on:

Creating clear contribution guidelines and issue templates
Managing pull requests using GitHub Actions for automation
Reviewing PRs efficiently and merging with proper checks
Supporting contributors through discussions and mentorship

I also introduced a contributor scoring system and auto-comment bots to keep engagement high and ensure fair recognition of all contributions.

Highs and Lows

The most rewarding moment was seeing first-time contributors successfully complete their PRs and share excitement about open-source for the first time.

On the flip side, managing a large influx of PRs and resolving merge conflicts was challenging especially when contributors submitted similar fixes. But, through collaboration and improved documentation, we made it work smoothly.

A lightbulb moment was automating repetitive maintainer tasks using GitHub Actions, saving hours of manual review and improving consistency.

Growth

Before Hacktoberfest 2025, my focus was mainly on building and managing personal projects. Through this maintainer journey, I honed my community management, code review, and automation skills.

I also learned how to better structure large-scale open-source repositories for long-term sustainability.

After Hacktoberfest, my goal expanded not just to build projects but to build open communities that empower learning and contribution.

Web hosting issues || GitHub Page is not showing up on the website?

Ajay Dhangar — Fri, 23 Sep 2022 08:41:50 +0000

I have created one repository on GitHub and hosted it with the help of the GitHub page. My issue is that if I have put all code (CSS and JavaScript code) in HTML, then it works, but if I have created another folder of CSS and JavaScript and saved the path in HTML, then it's not working. I don't understand why.

For example, you create one simple hello world website and try code from this condition.
