AI Categorization Logic

Tasks are automatically categorized based on keyword analysis:

💼 Work Category

Keywords: office, project, client, meeting, presentation, report, deadline, email, call, conference, proposal, budget, team, manager, work, job, business, professional, corporate, company, task, assignment, review, analysis, development, coding, programming, software, application, system, database, server

👤 Personal Category

Keywords: birthday, family, shopping, grocery, home, house, personal, friend, vacation, holiday, doctor, appointment, health, exercise, gym, hobby, book, movie, restaurant, dinner, lunch, breakfast, party, celebration, gift, anniversary, wedding, travel, trip, visit, clean, organize, repair, maintenance, garden, pet, car, insurance, bank, finance

Urgent Category

Keywords: urgent, asap, immediately, now, today, emergency, critical, important, priority, rush, quick, fast, soon, deadline, overdue, late, must, need, required, essential, crucial, vital, pressing, time-sensitive, hurry, instant, immediate

General Category

Default category for tasks that don't match any specific keywords.

Prerequisites

Viewing Tasks

 ALL TASKS
==================================================
1.  Submit client proposal [Work] - PENDING (Created: 2025-01-15 09:30:00)
2.  Buy birthday gift for mom [Personal] - COMPLETED (Created: 2025-01-15 10:15:00) (Completed: 2025-01-15 18:30:00)

Deployment to Subdomain (todo.saurabhh.in)

Step 1: Package the Application

mvn clean package
# Output: target/ai-todo-manager.jar

Step 2: Deploy to Server

# Upload to server
scp target/ai-todo-manager.jar root@your_server_ip:/home/deploy/

# SSH to server and run
ssh root@your_server_ip
cd /home/deploy/
java -jar ai-todo-manager.jar

Step 3: Apache Reverse Proxy Configuration

Create /etc/apache2/sites-available/todo.saurabhh.in.conf:

<VirtualHost *:80>
    ServerName todo.saurabhh.in
    DocumentRoot /var/www/todo

    ProxyPreserveHost On
    ProxyPass / http://localhost:8080/
    ProxyPassReverse / http://localhost:8080/

    ErrorLog ${APACHE_LOG_DIR}/todo_error.log
    CustomLog ${APACHE_LOG_DIR}/todo_access.log combined
</VirtualHost>

Step 4: Enable Site and Modules

sudo a2enmod proxy
sudo a2enmod proxy_http
sudo a2ensite todo.saurabhh.in
sudo systemctl restart apache2

Step 5: DNS Configuration

Add A Record in your domain provider (Hostinger):

• Name: todo
• Type: A
• Value: your_server_ip
• TTL: 3600
