1. Customer Service Agent

24/7 AI Customer Support Assistant

What is a Customer Service Agent?

A Customer Service Agent is an AI programmed to receive, process, and respond to customer requests automatically. It can replace or assist a customer service team, operating continuously 24/7 without breaks.

With natural language understanding capabilities, this Agent can communicate smoothly across multiple channels: websites, fan pages, Zalo, email, or internal company applications.

Common Use Cases

A Customer Service Agent helps businesses handle hundreds or even thousands of requests daily without increasing staff.

Practical examples include:

• Automatically answering frequently asked questions (FAQ)
• Guiding customers on order tracking, returns, and warranties
• Sending notifications and appointment confirmations
• Receiving and categorizing feedback or complaints
• Sending post-service satisfaction surveys

An AI customer service assistant operates continuously, ensuring that businesses never miss a request — even outside business hours.

Real-World Example

• Dental Clinic:
  Uses an AI Agent to confirm appointments automatically via Zalo and SMS, reducing 80% of reminder calls from reception staff.
• Online Cosmetics Store:
  Integrates AI assistants into websites and fan pages to handle inquiries about orders, shipping, and returns — cutting human-handled messages by over 50%.

Who Should Use It?

Customer Service Agent is ideal for:

• E-commerce and online retail businesses
• Spas, clinics, beauty salons, hospitals  
• Training centers, schools with many students
• Logistics, transportation, warranty, and maintenance services

If your business is overloaded with messages and calls or struggles to respond promptly, this is a solution worth implementing soon.

2. Sales Agent

Intelligent AI Sales Assistant for Automated Conversions

What is a Sales Agent?

A Sales Agent is an AI specifically designed to perform automated sales tasks. It can provide product consultations, personalize offers, respond to customers, and encourage purchases — without human intervention.

Often deployed as a sales chatbot or AI assistant integrated into websites, fan pages, apps, or email marketing campaigns.

Common Use Cases

AI sales agents help businesses engage and persuade customers directly at digital touchpoints, working 24/7 without missing opportunities.

Key examples:

• Product recommendations based on behavior and purchase history
• Cross-selling and upselling
• Responding to product queries, quotations, and payment guidance
• Creating personalized promotions for specific customer groups
• Sending timely sales messages (e.g., when a customer hesitates, abandons a cart, or revisits the website)

AI sales assistants keep customer contact alive even after business hours, increasing the chance of conversions.

Real-World Example

• Health Supplement Store:
  Uses AI to recommend immunity-boosting products when customers search for terms like “fatigue” or “low energy,” increasing conversion rates by 35%.
• Online English Center:
  Deploys an AI sales chatbot to segment learners by age and needs, then sends personalized trial learning paths — doubling the conversion rate.

Who Should Use It?

Sales Agent is best suited for:

• E-commerce and online retail businesses
• Fashion, cosmetics, health supplement brands
• Online education and training centers  
• Insurance, real estate, and personal finance agencies

If you want to boost sales without expanding your sales team, AI sales agents let you sell more, faster, and smarter.

3. Data Analyst Agent

AI Data Analyst for Insights & Action Recommendations

What is a Data Analyst Agent?

A Data Analyst Agent is like an in-house AI data analyst. It can read, interpret, and explain business data — and recommend specific actions — without requiring deep analytical skills from the user.

You can ask it questions in natural language, such as:

• “How are today’s sales?”
• “Which product is selling best?”
• “Has marketing spend increased unusually?”

Practical Applications

AI data assistants help businesses:

• Automatically compile revenue, cost, and KPI reports from multiple sources
• Interpret data in plain language instead of complex tables
• Suggest efficiency improvements to save budget or time
• Predict trends from historical data, such as next week’s revenue
• Answer ad hoc questions like, “Why did the conversion rate drop this week?”

This eliminates the need to open multiple Excel files or wait for the analytics team — insights arrive instantly.

Real-World Example

• Coffee Chain:
  Automatically sends branch-specific revenue reports every morning so managers can monitor performance without requesting manual summaries.
• Advertising Agency:
  Uses AI to analyze marketing channel performance, reallocating budgets according to actual conversion rates to improve ROAS.

Who Should Use It?

Data Analyst Agent is perfect for:

• Businesses with large amounts of sales, marketing, finance, and operational data
• Business owners or mid-level managers who need quick decisions without a BI/Data team
• Teams wanting to save time reading reports and avoid missing critical information

If you spend hours every week “digging” through data without decisive results, this AI assistant is worth trying immediately.

4. Workflow/Task Agent

Automating Internal Tasks & Workflows

What is a Workflow/Task Agent?

A Workflow/Task Agent is an AI that handles administrative tasks, reminders, report sending, progress tracking, and repetitive processes within a company.

It works like an internal assistant, helping teams save time and reduce errors in everyday repetitive tasks.

Real-World Applications of Workflow/Task Agent

These agents help businesses maintain stable work efficiency, ensure smooth coordination across departments, and free up staff from repetitive manual tasks.

Practical Applications:

• Automatically sending scheduled reports (daily/weekly/monthly) via email or internal systems
• Scheduling meeting reminders, tracking deadlines, and notifying relevant team members
• Tracking and updating task progress (checklists, task statuses) 
• Sending follow-up emails to customers or staff
• Triggering workflows when specific events occur (e.g., creating a new task when a large order comes in)

Workflow Agents can integrate with tools like Notion, Slack, Trello, and Google Workspace to keep work flowing smoothly without manual intervention.

Real-World Example

Media Agency: Uses Workflow Agent to remind weekly meeting schedules and automatically send meeting minutes to departments, saving 3–5 admin hours weekly.

SaaS Company: Configures an agent to send daily new-user reports directly to the CEO’s email, eliminating manual data exports.

Who Should Use It?

Workflow/Task Agent is ideal for:

• Businesses with clear, repetitive workflows
• Teams with many small tasks and tight deadlines
• Departments like operations, HR, accounting, and customer service
• Startups and SMEs wanting streamlined operations without sacrificing productivity

If you spend too much time “reminding” people, checking deadlines, or manually sending reports, a Workflow/Task Agent will help you work smarter.

5. Personal Assistant Agent

Smart AI Personal Assistant for Work & Life

What is a Personal Assistant Agent?

A Personal Assistant Agent is a digital AI assistant that helps you remember schedules, organize tasks, gather information, and remind you of important matters at the right time.

Unlike traditional calendar tools, it understands context, prioritizes work, personalizes suggestions, and proactively supports you daily — just like a real assistant.

Practical Applications of Personal Assistant Agent

• Reminding you of meetings, events, personal and work deadlines
• Summarizing important emails and messages
• Suggesting work priorities based on urgency and deadlines
• Quick search and summarization of requested information (news, reports, documents)
• Weekly work planning and daily reporting with ready-made templates
• Suggesting rest breaks to prevent burnout

Personal Assistant Agent helps you reduce stress, stay focused on what matters most, and work in an organized way—without having to “remember everything” yourself.

Real-World Example

• Project Manager: Uses AI to compile morning email summaries and meeting reminders, starting the day more smoothly.
• Senior Executive: Uses AI to summarize industry news and highlight key weekly tasks, saving 4–5 hours of preparation time.

Who Should Use It?

Personal Assistant Agent is best for:

• Entrepreneurs, managers, and freelancers with busy schedules
• Multitaskers who need better organization
• Office workers wanting to save time on emails, notes, and planning

Anyone who wants to improve personal productivity intelligently.
