## In short

- A rule-based bot costs $300-900 and fits lead forms, fixed-slot booking, price lists and loyalty programs.
- An AI chatbot starts at $1,200 and is justified where there is a large knowledge base, consultative service and free-form questions.
- The decision rule: if you can script 90% of the answers in advance, you need a rule-based bot; if not, consider AI.
- PaintBox case: choosing paint from a described task cannot be solved with buttons, the variations are too many.

## A Regular Bot (Button-Based / Scripted)

It works on fixed scenarios: press a button, get an answer. The logic is defined in advance, and the bot doesn't deviate from it.

When this is exactly what you need:

- accepting requests through a form;
- booking with fixed time slots;
- sharing a price list or catalog;
- a loyalty program with points;
- notifications and reminders.

> **Cost: $300-900**
>
> Fast to launch, predictable behavior, low cost of error.

## AI Chatbot

Handles free-form requests, "understands" context, and can answer open-ended questions, analyze, and make recommendations.

When AI is genuinely worth it:

- a large knowledge base (hundreds of questions phrased in different ways);
- consultative services (medicine, law, product selection);
- personalized recommendations based on behavior;
- 24/7 customer support with no operator;
- message analysis and routing between departments.

> **Cost: From $1,200**
>
> Requires setting up a knowledge base, testing, and monitoring.

## Real-World Example: PaintBox

Darobots built an [AI chatbot](/ai-products) for PaintBox, a service that helps customers pick paint and materials for renovation. Customers asked questions like "what paint works for a humid room with a kid's bedroom" and got specific recommendations from the catalog.

- **Client:** What paint works for a humid room with a kid's bedroom?
- **System:** Selecting options from the catalog…
- **PaintBox:** You'll need a washable, odor-free, moisture-resistant paint. I've picked three options across different budgets
- **Client:** How much do I need for 18 m²?
- **System:** Calculating material usage…
- **PaintBox:** For 18 m² in two coats, 5 L will be enough - that's one bucket
- **Client:** Great, please submit a request
- **PaintBox:** Passing this to a manager: washable paint, kid's bedroom, 18 m², 5 L. They'll confirm availability and delivery

A regular button-based bot couldn't have handled this: too many variations of the question. AI processes them naturally, offers options, and hands the request to a manager already complete with the customer's preferences. Details in the [PaintBox case study](/cases/paintbox).

## The Main Rule for Choosing

> **Ask Yourself**
>
> "Can I script 90% of the answers in advance?" If yes, you need a scripted bot. If not - if customers ask questions in free form and you need flexibility - consider AI.

Darobots offers both types of solutions. We help you figure out which one fits at the briefing stage, for free.

> **Conclusion**
>
> AI is a powerful tool, but not a cure-all.
> 
> The right approach: understand the task first, then choose the technology. Darobots can help you figure it out - reach out and get a recommendation tailored to your business.
