The AI agents are bright, but not ‘intelligent’ – they need a lot of guidance and the language that is used is critical. The instructions in the system prompt of the AI Agent node are critical. Getting the language right in that is very important. It needs to be consistent across the tools.

For example, when designing your system, you need to decide if you’re talking about records, ideas, content, pages, posts or databases – you need a consistent vocabulary in order for the AI to be able to understand and take action.

Testing is particularly challenging because AI responses can vary, making it difficult to ensure reliability. The ultimate goal is to create an effective Master Control Program (MCP) that can manage these interactions efficiently.

Setting up AI agents in n8n presents significant challenges, particularly when it comes to testing them effectively. I’ve been struggling with making MCP (Master Control Program) work in this context.

Key observations about AI agents:
1. AI agents are bright but not truly ‘intelligent’ – they require extensive guidance and structure
2. The language used in instructions is absolutely critical
3. The system prompt in the AI Agent node is particularly crucial for success
4. Getting the language right requires careful consideration and planning
5. Consistency in vocabulary is essential – you must decide whether you’re talking about records, ideas, content, pages, posts, or databases and stick with that terminology
6. Without a consistent vocabulary across tools, the AI will struggle to understand and execute the desired actions
7. Testing is particularly challenging because AI responses can vary based on subtle differences in prompts

The dream is to have a well-functioning MCP system where the AI can effectively understand and process information across different tools and contexts, but achieving this requires meticulous attention to language and instructions.

The Text-to-Speech Revolution: Why Eleven Labs Stands Out

In the rapidly evolving landscape of AI voice technology, Eleven Labs has emerged as a standout player, pushing the boundaries of what’s possible in text-to-speech synthesis. Having tested numerous voice cloning technologies, I’ve found that Eleven Labs offers a compelling combination of quality and versatility that sets it apart from competitors like F5-TTS. Let’s dive into what makes this platform the go-to choice for serious voice projects.

Unparalleled Voice Quality: The Eleven Labs Difference

The first thing you’ll notice when using Eleven Labs’ professional voice cloning service is the exceptional quality of the output. Unlike the often robotic or artificially smooth voices from competing platforms, Eleven Labs produces voices with:

• Natural speech patterns and inflections that mimic human cadence
• Appropriate pauses and emphasis that convey genuine meaning
• Preservation of subtle vocal characteristics that maintain personality
• Accent accuracy that respects linguistic diversity

This quality difference isn’t just noticeable to audio professionals—even casual listeners can distinguish an Eleven Labs voice from standard text-to-speech solutions. The voices simply sound more human, creating a more engaging and authentic experience.

Professional Voice Cloning: Worth the Investment

While Eleven Labs offers a quick cloning option, the platform truly shines with its professional-grade voice cloning service. This premium offering requires:

• A minimum of 30 minutes of clean, high-quality audio samples
• Ideally, up to 3 hours of diverse speech patterns for optimal results
• Consistent recording conditions to maintain audio fidelity
• A variety of speech patterns, tones, and emotional ranges

The investment in collecting this audio pays substantial dividends in the final product. Unlike F5-TTS, which produces acceptable results from just 15 seconds of audio, Eleven Labs’ approach is fundamentally different—it captures the complete essence of a voice rather than just its basic characteristics.

Real-World Applications: Where Eleven Labs Excels

The superior quality of Eleven Labs makes it particularly valuable for:

• Professional content creation: Podcasts, audiobooks, and narration where voice quality directly impacts user experience
• Brand voices: Companies seeking a consistent, distinctive voice across customer touchpoints
• Accessibility solutions: Creating natural-sounding audio versions of written content
• Educational materials: Engaging learners with human-like instruction
• Entertainment and gaming: Developing realistic character voices without hiring multiple voice actors

The Technology Behind the Quality

Eleven Labs achieves its impressive results through sophisticated deep learning models specifically designed for voice synthesis. Their approach likely involves:

• Advanced neural networks trained on vast datasets of human speech
• Models that capture micro-variations in speech patterns
• Algorithms that understand contextual emphasis and emotional nuance
• Continuous refinement through machine learning techniques

This technical foundation explains why more data leads to better results—the models can extract increasingly subtle patterns from larger samples, resulting in more natural-sounding voices.

Making the Choice: When to Use Eleven Labs

While Eleven Labs’ professional cloning isn’t the quickest or least expensive option, it’s the clear choice when voice quality matters. Consider Eleven Labs when:

• The voice will represent your brand or content publicly
• You need extended speech that maintains natural qualities
• Accent preservation and speech authenticity are priorities
• You want listeners to connect emotionally with the audio

Conversely, if you need a quick solution with minimal setup time and lower quality requirements, F5-TTS might be sufficient. But remember: your audience will notice the difference.

Conclusion: Quality That Speaks for Itself

Eleven Labs has positioned itself at the forefront of voice synthesis technology by prioritizing quality and authenticity. While it requires more input data than some alternatives, the results speak for themselves—literally. For professionals serious about creating compelling voice content that engages audiences and maintains human-like qualities, Eleven Labs represents the current gold standard in accessible voice cloning technology.

The Power of n8n.io

n8n.io is an amazing automation solution that stands out in the crowded field of workflow automation tools. As an open-source platform with a visual workflow builder, it lets you connect different services and automate complex processes without deep technical knowledge. The flexibility to self-host and the extensive integration library make it a powerful option for businesses of all sizes.

When Templates Become a Distraction

While n8n offers numerous templates designed to jumpstart your automation journey, I’ve found these can sometimes be more of a distraction than a help. Many templates include random services that you might never have used before or have any intention of using regularly.

The workflow often goes like this: you search for a template that sounds “about right” for what you’re trying to accomplish. The thumbnail and description look promising, so you click to implement it. Then reality hits – the template requires you to connect to three or four different services you’ve never heard of before.

The “Random Grab Bag” Problem

This creates what I call the “random grab bag” problem. To use the template, you need to:

• Create accounts with unfamiliar services
• Generate API keys or authentication tokens
• Learn the basics of how each service works
• Manage free tier limitations

Before you know it, you’re managing a collection of demo accounts across disparate services just to implement a single workflow. This scattered approach can quickly become unwieldy, especially if you’re implementing multiple templates.

Templates Often Don’t Follow Latest Practices

Another issue is that many templates don’t follow the latest build options available in n8n. The platform evolves rapidly, regularly adding new nodes and capabilities that can streamline workflows. However, templates often lag behind, using older, more complex approaches rather than newer, more efficient methods.

This means you might be learning outdated practices or implementing unnecessarily complex solutions when simpler options now exist.

Making Better Use of n8n

Despite these challenges, n8n remains an excellent automation platform. Here’s how I’ve found it best to approach it:

1. Start from scratch – Build simple workflows connecting services you already use rather than adopting complex templates
2. Use templates as inspiration – Study the logic and approach of templates without necessarily implementing them exactly as designed
3. Focus on core services – Prioritize connecting the tools your organization already uses daily
4. Regularly audit your connections – Periodically review and clean up unused service connections to avoid the “random grab bag” effect

Conclusion

n8n.io is a powerful automation platform with tremendous potential to streamline workflows and connect diverse services. The template system, while well-intentioned, can sometimes lead to a scattered approach that leaves you managing numerous random accounts.

By focusing on building workflows that connect your core services and using templates only as guidance rather than gospel, you can harness the full power of n8n while avoiding the pitfalls of template-driven development.

I haven’t played with a no-code platform for a while, but it looks interesting. Node-red was the last one I played with, which was mildly infuriating.

This seems to have more of an ai focus…..but we will see.

this is a quick index to the various ai tools I have been playing with, and I will add extra links to posts where I expand on my experiments and thoughts

open-hands / devin + claude 3.5 & 3.7

this was very easy to setup, provides a coding buddy, agent setup. however, claude gets overwhelmed with context/tokens and you can become rate limited incredibly fast.

when it is working it is fantastic, but until the tokens are managed better, not that useful.

F5-TTS + local models

mildly involved setup, playing with this for voice cloning for possible podcast ideas. wow. incredible.

runs locally on a 4gb RTX 3050. it isn’t perfect, but creating a script in gemini and feeding that into F5TTS – the quality is impressive and I am sure it can be improved with playing.

ms copilot / ms365

easy to setup, hard to get good results from, very useful in day to day office work.

irritating licensing.

lm studio – local models

if you have a 4gb+ GPU this is definitely worth playing with.

runs local open source models. your GPU will be primary limitation, but you can still get good use from the smaller models.

trivially easy setup, great community on reddit. this is a playground for learning about how llm models work.
