We have been conducting AI coding and tools use benchmarks to test the real-world capabilities of popular AI agents. In this article, we listed the best AI agent tools:

These AI agents are not yet fully autonomous; most serve as “co-pilots,” low-code LLM or logic-based tools where AI handles the heavy lifting of research and repetitive tasks execution, but with human oversight at key decision points.

Each of these platforms combines LLMs with tools and structured reasoning components like intent recognition, action execution, memory, context, and reflection—core traits of agentic AI systems.

  • Cursor: AI code editor
  • Otter.ai: AI note-taking agent
  • Averi: AI marketing content creator 
  • Make (Celonis): Scalable low-code automation
  • Zapier, n8n: Business workflow orchestration
  • Kompas AI: Deep research and report generation platform.
  • LangGraph: Production-grade framework for complex agentic workflows
  • Beam AI: Document-heavy workflows
  • Relevance AI:  Embedded analytics + decision flows
  • IBM watsonx Orchestrate: Enterprise-grade orchestration

What is an AI agent?

An AI agent is more than just an LLM responding to prompts—it’s a looping system that uses LLM output to drive actions, track context, and continue reasoning until a goal is met.

However, there is no strict definition of what an “Agent” can be; it can be defined in several ways:

  1. Traditional AI defines agents as — systems that interact with their environment.
  2. Some analytics firms define agents as — fully autonomous systems that operate independently over extended periods, using tools such as functions or APIs to engage with their surroundings and make decisions based on context and goals.2
  3. Others use the term to describe as — more prescriptive implementations that follow predefined workflows.3

Here are the factors that cause an AI system to be considered more agentic:

FactorDescription
Language → tool actionConverts natural input to structured tool/API calls.
Prompt ownershipPrompts are designed and versioned for consistency.
Context memorySaves past steps to inform future decisions.
Tool as outputTools are explicit outputs like JSON, not hidden logic.
Start/Stop via APIAgents can pause or resume through APIs.
Error memoryErrors are summarized into memory for retries.
Focused agentsEach agent is narrow in scope and easy to maintain.
Multi-channel triggerAgents can start from Slack, CLI, email, etc.
State managementTracks the state of tasks and peer agents.

Levels of agentic AI systems

2Strategic task automationRPA tools🟠 Equal to 50% of skilled adultsExecutes user-defined tasks with tools
1Rule-based automation (deterministic)IF/THEN logic🔴 Equal to unskilled humansScripted workflows

Level 1. Rule-based automation (deterministic)

  • At the most basic level, a coding assistant can generate code snippets in response to developer prompts.

Level 2. Strategic task automation

  • A more capable agent can analyze an existing codebase and tailor its output accordingly — even writing code preemptively to satisfy a unit test once it’s been written.

Level 3. Context-aware and reflective agents

  • A more agentic tool could not only write code but also compile and run it within a controlled test environment.

Level 4. Highly autonomous, adaptive systems

  • Looking ahead, highly autonomous AI agents may be able to deploy fully tested applications to production through automated pipelines — triggered by natural language instructions and finalized with human approval.

Of note, listed agents are context-aware and reflective agents (level 3).

AI agents: Use cases and real-life examples

1. Task automation

AI agents can undertake a variety of repetitive and time-consuming tasks. These agents can read and extract data from documents. You may instruct the agents to cross-check the extracted data against rules to ensure data correctness. This degree of precision makes AI agents suitable for monotonous jobs such as data input, processing, and invoicing management.

Real-life example:

Canon suffered a four-month backlog after using traditional invoice processing until it opted to use AI agents. They used 135 AI-powered UiPath robots to extract data from invoices, verify it, and enter it into accounting software.6

2. Resource optimization

Businesses may set up AI agents to collect data from many sources, including production logs, sales data, and customer communications. This helps to evaluate data to find patterns, trends, and anomalies that could optimize resource allocation.

Real-life example:

Avi Medical’s integrated multilingual AI agents automated 80% of patient questions, cutting median response times by 85%.7

3. Provide 24/7 omnichannel support

AI agents are available 24/7, guaranteeing that customers receive constant service. These smart assistants can interpret client requests and respond like people.

Real-life example:

Storytel employed an AI agent to roll out automated support in 13+ languages and counting in 109 languages. The company offers its customers more options for resolving their queries 24/7.8

4. Personalized service

AI agents use client data, such as purchase history and browsing activity, to provide tailored experiences. This learning technology enables AI agents to make suggestions and provide tailored replies to specific clients.

Real-life example:

Stitch Fix used agents to provide clothing recommendations to their customers, resulting in a reduction of 30% decrease in chat AHT.9

5. Effective issue resolution

AI  agents can collect and evaluate the necessary data to provide relevant solutions to frequent consumer inquiries. These agents can continuously improve their replies, resulting in effective service.

Real-life example: Bank of America employs a chatbot named Erica. The virtual agent does basic duties such as monitoring account balances and offering budgeting advice to customers, decreasing response times.10

6. Fraud detection

AI agents can track transactions in real-time to detect and prevent fraudulent activity. They can detect unusual activity and highlight possible fraud, reducing the expenses associated with fraudulent operations.

7. Optimizing inventory levels

Companies can optimize inventory levels with AI agents by leveraging demand prediction

8. Tailored real-time feedback

AI agents provide tailored feedback by assessing their replies and recommending areas for growth.

9. Content suggestions

AI agents suggest individualized information and resources depending on the learner’s progress and interests. It guarantees that the learning experience is relevant and interesting.
