📚 Project docs
- 🧭 VISION.md – Why LearnHub exists, what it is (and is not), and the long-term dream.
- 🤖 AI_FEATURES.md – How AI-powered flows, global entry points, per-summary buttons, and live examples.
- 🗺 ROADMAP.md – What’s shipped, what’s in progress, and where the project is headed next.
- 🤝 CONTRIBUTING.md – How to request new topics, report issues, and improve docs / code.
If you are new here, read VISION first, then skim AI_FEATURES, and finally check the ROADMAP and CONTRIBUTING.
Important disclaimer
This repository contains my personal notes and interpretations based on third-party resources (such as online courses, YouTube videos, books, and mock interviews).
These summaries are:
- Not official material,
- Not endorsed by the original creators, and
- Not intended to be a replacement for the original courses, books, or videos.
All rights to the original source content remain with their respective creators.
If you are the owner of a work and you are unhappy about the presence of a summary related to your material in this repository, please contact me at alisolphp@gmail.com. I will review it and remove it if necessary as soon as possible.
💡 Why this repo exists (short version)
LearnHub is a curated collection of concise, high-signal summaries for courses, YouTube videos, books, and mock interviews.
It is designed to help you:
- learn faster,
- review smarter (for example before interviews),
- and use your favourite programming language and natural language when drilling into details with an AI assistant.
For the full story and philosophy, see VISION.md.
🧠 Using this repo with AI
You can combine these summaries with an AI assistant to:
- Ask follow-up questions about any section of a summary.
- Turn flashcards into interactive Q&A practice.
- Translate explanations into your preferred tone and natural language.
- See examples in the programming language you are most comfortable with.
- Get freshness notes after each explanation (useful for older books and videos).
- Simulate interview-style discussions using the mock interview summaries.
- Go deeper into the topic with advanced AI hints at the end.
Typical workflow:
- Open a
summary.*.mdfile for the topic you are studying. - Use the AI buttons at the top (teach / flashcards / quiz / projects / …), or:
- Highlight a section and ask your AI assistant to go deeper, ask “why?”, or request code examples.
See AI_FEATURES.md for detailed routes and prompts.
🧭 Contributing
This is an opinionated, curated project. Summaries are not crowd-sourced – they are maintained by the project owner (and maybe a small trusted core team later).
You can still help a lot by:
- requesting new topics / resources,
- reporting broken links or AI buttons,
- suggesting better prompts and workflows,
- improving docs, and
- sending small, focused code improvements.
Read CONTRIBUTING.md for:
- what kinds of contributions are welcome right now,
- what is out of scope (e.g. editing summaries),
- and how to open good issues / PRs.
