AI \u2013 a real game changer, or rather a marketing buzzword that sells well? It’s hard to deny that AI has already changed the IT world, including solutions related to process automation. It seems that artificial intelligence, and AI agents in particular, are becoming a perfect complement to robotic business processes, further reducing repetitive activities and, as a consequence, additionally freeing up financial resources in selected areas of the company.<\/p>\n\n\n\n

Rese<\/a>a<\/a>rch<\/a> points to significant savings in AI+RPA vs traditional RPA<\/strong>, despite additional expenditure on licenses, infrastructure, and maintenance of automated systems.<\/p>\n\n\n\n

For example, savings in the area of employee costs can range from 50% to 70% for solutions using AI, compared to traditional RPA solutions, where cost reductions range from 40% to 60%. The increase in quality by reducing errors in the process is even more visible (60-80% vs 35-65%). It’s hard not to resist the temptation to introduce or switch to AI+RPA solutions when you see numbers like these \ud83d\ude0a.<\/p>\n\n\n\n

This article is a review due to the extensiveness of issues related to the use of AI and AI agents in robotic work processes. We will look at this issue more from the perspective of a Business Analyst (which I am \ud83d\ude0a), leaving the technical details only at the level necessary to understand the definitions, concepts, or examples of applications presented.<\/p>\n\n\n\n

I will focus on two well-known tools: UiPath<\/strong> and n8n<\/strong>.<\/p>\n\n\n\n

First, I will present the main differences in architecture, costs for the customer, and TCO. We’ll take a look at a few basic domains of AI agent use. Next, I will briefly present a comparison of the approach to Process Mining<\/em>. Finally, I will touch on the topic of the security of solutions using AI<\/strong> agents in automated business processes. <\/p>\n\n\n\n

Tool comparison: Architecture, costs & TCO (factsheet)<\/strong><\/strong><\/h2>\n\n\n\n

Before we move on to the implementation level of AI agents, it is important to look at the differences in architecture, cost model, and implementation time of both platforms.<\/p>\n\n\n\n

The business model of the two solutions differs significantly. Both tools have different implementation potential.<\/p>\n\n\n\n

UiPath is a product that will work well in infrastructure and systemically complex environments, often still maintaining legacy systems such as banks, insurance institutions,<\/strong> or big pharma.<\/p>\n\n\n\n

The n8n, on the other hand<\/strong>, is rather dedicated to lightweight solutions, e.g., in e-commerce.<\/p>\n\n\n\n

Business domains of use of AI Agents<\/strong><\/strong><\/h2>\n\n\n\n

So, let’s see some examples of how both platforms are used.<\/p>\n\n\n\n

UiPath <\/strong><\/h2>\n\n\n\n

Banking & Finance<\/strong><\/h3>\n\n\n\n

Application:<\/strong> Autonomous verification in KYC (Know Your Customer) and AML (Anti-Money Laundering) processes.<\/p>\n\n\n\n

Agent action: <\/strong>The AI agent does not perform operational tasks directly, but decides which workflow to run. Data extraction from unstructured documents (scans, reports) is carried out by dedicated Document Understanding (DU\/IXP) components. The agent only uses the results of their work. Based on this information, it makes a decision to delegate tasks to classic RPA robots, which are responsible for proper navigation through the graphical interfaces of old banking applications and state registers. The process ends with the generation of a structured risk report for the analyst.<\/p>\n\n\n\n

Wholesale and B2B Distribution  <\/strong><\/h3>\n\n\n\n

Application:<\/strong> Intelligent Order Processing.<\/p>\n\n\n\n

Agent action: <\/strong>Instead of a rigid robot reading standardized EDI files<\/a>, the AI Agent coordinates the process of handling emails from contractors. It delegates the analysis of attachments (Excel, PDF, notes) to the data extraction components, and then commissions RPA robots to verify the states in the WMS. In the event of warehouse shortages, the WMS, based on precisely defined business rules and product mappings, prepares a replacement project. Due to B2B relationships, this proposal is most often addressed to the salesperson through the UiPath <\/strong>Action Center<\/em> for final validation before sending it to the customer.<\/p>\n\n\n\n

Retail & E-commerce (Retail)<\/strong><\/h3>\n\n\n\n

Although e-commerce is often associated with a modern API, large retail chains have a highly fragmented architecture that combines online sales with point-of-sale systems.<\/p>\n\n\n\n

Application: <\/strong>Supply chain hyperautomation and omnichannel complaint handling.<\/p>\n\n\n\n

Agent action: <\/strong>The customer reports damage to the goods. The AI<\/strong> agent analyzes the content of the request for intent, after which it runs RPA robots to<\/strong> collect the purchase history from the CRM<\/a> and verify the batch in the logistics system (serial defect exclusion). Further steps depend on the financial risk thresholds and business rules implemented in the CRM. Low-value reports may result in robots being commissioned to initiate a refund and order a courier. Cases that exceed the designated risk thresholds or require a non-standard assessment are automatically suspended and forwarded to the Action Center<\/em> for a final decision on reimbursement.<\/p>\n\n\n\n

n8n <\/strong><\/h2>\n\n\n\n

And how can we use the n8n platform<\/strong>?<\/p>\n\n\n\n

IT Service Management (ITSM) in DevOps  <\/strong><\/h3>\n\n\n\n

Application:<\/strong> Autonomous evaluation and segregation of alerts and automatic fault repair (Self-Healing Systems).<\/p>\n\n\n\n

Agent Action:<\/strong> When an alert is received (Webhook<\/a> from the system Datadog<\/a>), Agent AI<\/strong> examines error logs, searches the knowledge base in Confluence,<\/a> and assigns tasks to engineers in the system Jira<\/a>.<\/p>\n\n\n\n

Modern E-commerce and Marketing Automation (Startupy\/Scaleupy)<\/strong><\/h3>\n\n\n\n

Purely digital sales environments (based on platforms such as Shopify, Stripe, Klaviyo).<\/p>\n\n\n\n

Application: <\/strong>Hyper-personalization and abandoned cart rescue.<\/p>\n\n\n\n

Agent action:<\/strong> When a customer with a high LTV (Life-Time Value) abandons a high-value cart, the Agent in n8n<\/strong> analyzes their previous purchases and generates a unique, tailored discount code in Shopify in real-time, after which they send a highly personalized SMS or email (using LLM models to set the right tone of communication).<\/p>\n\n\n\n

B2B and Marketing (Lead Enrichment) <\/strong><\/h3>\n\n\n\n

Sales and marketing departments use more than a dozen SaaS tools (CRM, mailing platforms, social media), which makes them an ideal environment for API-based integration platforms.<\/p>\n\n\n\n

Application:<\/strong> Autonomous qualification of leads (Lead Research) and creation of personalized campaigns (Outreach) on a large scale.<\/p>\n\n\n\n

Agent Action:<\/strong><\/p>\n\n\n\n
