The most expensive confusion on the chatbot market
In the Peruvian technology market, the terms "chatbot" and "AI agent" are used synonymously. They are not. And confusing them can lead you to hire the wrong solution, waste budget and end up with a system that does not serve what you needed.
This article is technical but not difficult. In the end, you will be clear about which of the two your company needs and what questions to ask any supplier.
What is a flow chatbot (and what is it for)
A flow chatbot is a decision tree. The user chooses from predefined options and the bot executes predefined responses. If the user types something that is not in the tree, the bot does not know what to respond.
It's reliable, predictable and more economical. It works perfectly when the use cases are known, finite and repeatable: reservations, FAQs, schedule queries, order tracking.
- Advantages: low cost, high reliability, easy to audit, no interpretation error.
- Limitations: does not understand free language, does not handle exceptions, requires manual updating.
- Reference price: S/ 2,000 – 8,000 (development) + S/ 200 – 500/month (maintenance).
- Best for: FAQ, agendas, order status queries, linear sales flows.
What is an AI agent (and when do you need one)
An AI agent uses a language model (GPT, Claude, or others) to understand free text, reason about the user's query, and generate responses that adapt to the context. It can handle thousands of variations of the same question, remember what you said earlier in the conversation, and perform actions like searching external systems for data.
The AI agent does not follow a decision tree. Make decisions for yourself within the limits you define. That makes it powerful but also more expensive and harder to predict.
- Advantages: Understands natural language, handles exceptions, scales without manual reprogramming, improves over time.
- Limitations: Higher cost, may "hallucinate" incorrect answers, requires careful configuration and testing.
- Reference price: S/ 10,000 – 40,000 (development) + S/ 800 – 2,500/month.
- Best for: complex customer service, technical support, consultative sales, document analysis.

The table that simplifies the decision
Answer these questions to find out what you need.
| Situation | Flow Chatbot | AI Agent |
|---|---|---|
| My use cases are predictable and finite | ✓ Ideal | × Oversized |
| Users write freely without following menus | × Not useful | ✓ Required |
| I need integration with several external systems | △ Possible but limited | ✓ Native |
| I have a tight budget (<S/ 8,000) | ✓ Viable | × Not feasible |
| I want to scale without rescheduling the bot | × Requires manual labor | ✓ Automatically scale |
The hybrid option: the best of both worlds
For many Peruvian companies, the optimal solution is a hybrid: a flow chatbot to handle first contact and simple cases, with an AI agent activated for complex or off-menu queries. This approach reduces costs by not having to pay for AI at every interaction, and maintains reliability in critical flows.
At Alaz we implement this hybrid architecture for companies that need efficiency at scale but without giving up intelligence in difficult cases.
