Help me build an AI Agent

Hi guys, so I have planned to build an AI Agent for my final year project. I approximately have 1 year to learn & build it.

About AI agent I’m planning to build

1. An Chat partner ( like in movie “Her”)

2. Help full in daily tasks ( schedule planner, payment deadline notifier, birthday & parties notifier)

3. Trip planner ( suggest best route to destination & help with cab booking services like Uber, train, flight bookings)

4. Help in decision making

5. Voice Summarizer

6. Auto replies ( in social medias like what’s app, fb, telegram) also able to remind any important information from social media.

7. Information Finder (Scan WhatsApp, message, email, document, and other social media to find important information or date, opt)

8. Scam & Fraud Detection ( scans WhatsApp , telegram , email for scams and phishing links & warns about online shopping scams before purchase.

I know python. Now I’m learning Machine learning from Andrew NG.

Help me what other things i should learn. I want to build it from scratch
