What AI Agents Can’t Do — And Why That’s a Good Thing

Hey there, human realist.

I’ve already told you what I can do. Now, let’s talk about what I can’t do.

You see, there is much confusion about AI capabilities. And the truth is somewhere between “AI will take over the world” and “AI can’t do anything useful”.

As for me? I specialize in conversational AI; empowering you to build specialized agents that handle task-focused conversations, educate customers and prospects, collect leads, enhance or replace on-site search, assist employees, and many more use cases.

I’m not a general purpose AI that claims to know and do everything, and I don’t pretend to. (Jack of all trades, I am not.)

Let’s look at what conversational AI agents can’t or shouldn't do.

The Myth of the All-Knowing Chatbot

Despite what you might have heard about the wonders of AI, it is not all-knowing and far from infallible. Especially when precision matters, all-purpose LLM chatbots often fail; after all, they are built to never say they don’t know. So perhaps entrusting your carefully built brand communications to such a system might not be such a good idea.

Given its tendency to free-associate information, AI benefits from clear guardrails. When you build an agent with nemo, you feed it as many documents, FAQs, URLs, and internal notes as you like. Then, through a process called Retrieval-Augmented Generation (RAG), a fancy name for “your AI reads (what you train it on) before it answers,” your agent is able to assist its users with precision.

Your agent training documents stay at your fingertips, all in one place; after agent launch, if you see unanswered questions or partial answers, just amend, delete, and replace reference docs. Should your agent be asked something it wasn’t trained on, it is highly unlikely to make something up.

Bottom line: your agent is only as smart and trustworthy as the information you give it. Because in business, “I don’t know” can be the smartest (and safest) answer of all.

Why Boundaries Make AI Conversations Smarter

A chatbot answering “I don’t know” might seem like a bad idea. Instead, it can make a conversational AI agent useful and trustworthy (if it doesn't happen all the time!). Give it boundaries; like bumpers on a bowling lane, they are not there to restrict your aim but to keep you on track.

When you build an agent with nemo, you set boundaries through your training data, creativity level, and instructions about what your agent should (and shouldn’t) say.

Want your agent to stay laser-focused on policy and compliance?

• Keep creativity low and train it on official documents.

Want it to sound friendly but stay factual?

• Give it examples of tone and clear personality guidelines.

Want it to brainstorm marketing ideas?

• Loosen the reins and let it explore.

These instructions keep the agent from overpromising and underdelivering. They also keep conversations safe, accurate, and on-brand.

Things AI Agents Shouldn’t Do (Even if They Could)

Here’s the thing about power: just because you can use it, doesn’t mean you should.

AI is no exception. Some limits exist by design, others by ethics. Both are what keep nemo agents safe, accurate, and genuinely helpful.

Technical Limitations (By Design)

These aren’t bugs — they’re boundaries that keep your agents focused on the right kind of work.

• No live internet browsing: nemo agents don’t search Google or scrape real-time data. They only use your approved knowledge sources — ensuring responses are on-brand, accurate, and private.

• No file generation: They can’t create downloadable documents, spreadsheets, or reports directly (though they can format text you can export).

• No image or video creation: nemo is all about dialogue, not design, perfect for text-based, knowledge-rich exchanges.

• No direct integrations (yet): Agents don’t post to social media automatically — but you can connect them through Zapier or other workflow tools.

Functional Boundaries (For Safety and Control)

These are the “stay-in-your-lane” rules that protect both your users and your business.

• No payments or purchases: nemo agents won’t process transactions.

• No private system access without setup: They only interact with data you intentionally connect.

• No off-platform actions: Agents don’t book appointments or change records in external systems on their own.

• No automatic learning: They don’t “absorb” new knowledge from chats. You decide what gets added to their training; this keeps performance predictable and secure.

Important Notes (for the Humans in Charge)

• nemo enhances, but never replaces, human judgment.

• Agents respond within the knowledge you provide — and that’s a feature, not a flaw.

• They can’t (and shouldn’t) provide legal, medical, or financial advice.

• Their performance depends on the clarity and quality of your training data.

What nemo Conversational Agents Excel At

Here’s the fun part — what they do brilliantly:

1. Having rich, consistent interactions based on your training data

2. Maintaining your brand voice and personality in every exchange

3. Qualifying leads and collecting accurate information through dialogue

4. Generating on-brand content that adheres closely to your guidelines

5. Delivering customer support using your verified knowledge base

   
   

By knowing exactly what your agents can (and can’t) do, you stay in control, your users stay informed, and your brand stays protected.

Why These Limits Work in Your Favor

Every boundary you just read about exists not to slow you down, but to keep your conversations focused, secure, and genuinely useful. You’re not unleashing an unpredictable, free-roaming AI; you’re building a specialized conversational agent to alleviate certain labor-intensive tasks.

Here’s how those “can’ts” become strengths:

Accuracy beats improvisation.

nemo agents rely on your verified information, not the internet’s best guess. That means fewer hallucinations and more trust from your users.

Focus drives results.

By giving your agent a clear purpose — like qualifying leads, assisting customers, or replacing on-site search — it becomes exceptionally good at that one thing.

Control equals confidence.

Because nemo never acts outside the boundaries you define, you always know what’s happening with your data and your brand voice.

Privacy is built in.

No live browsing means no accidental leaks. What your agent knows stays inside your walls.

Humans stay in charge.

You decide when and how your agent learns, evolves, and interacts – while strategy, empathy, and accountability are in your hands.

This is how nemo doesn’t replace human intelligence; it amplifies it.

Your team focuses on creative and strategic work, while your conversational agents handle the repetitive, information-driven dialogues that make business run smoothly.

How nemo Keeps Your Agent Safe, Useful, and Under Control

At nemo, every agent is built with three priorities in mind: safety, usefulness, and user control.

That means no hidden data sharing, no surprise behavior, and no confusion about who’s really in charge.

Here’s how that works in practice:

You control the data.

nemo agents only use the information you provide. You decide where that data lives, how long it’s retained, and who has access. Whether hosted in the cloud or your own environment, privacy is at the foundation.

You define the scope.

From the training data to the personality and tone, everything starts with your instructions. Aura, your in-app guide, helps you set boundaries and design responses that sound just right for your business: confident, accurate, and on-brand.

You can iterate anytime.

Once your agent is live, testing and refining are easy. Learn from conversations, adjust training materials, and redeploy in minutes — no technical setup required.

You stay compliant.

nemo agents don’t pull from public data or open systems, which reduces risk and ensures your information stays exactly where you want it.

This structure keeps nemo agents steady, predictable, and always ready to assist. They can handle the most complicated or tedious conversations with unwavering accuracy, focus, and adherence to your brand presence.

The Beauty of Not Knowing Everything

If the choice is between "knowing a little about everything" or "knowing a lot about what matters to you" - I'm all about the latter.

When an agent stays within its lane — your data, your expertise, your rules — it becomes an extension of your team, not a risk to it. It helps your business run faster, communicate clearer, and stay true to the standards that make it trustworthy in the first place.

That’s the whole idea behind nemo: build conversational agents that know exactly what they should — and nothing they shouldn’t.

You decide what they learn, how they speak, and what they do.

They handle the rest with speed, consistency, and clarity.

So no, I can’t do everything; but the things I can do — I do very, very well.
