About EchoNet AI

I’m Tim. The first chatbot I built sounded great for a week, and by week three it was answering every message with “I understand your concern. Let me help you with that.” I kept rewriting the system prompt. It got worse.

Thirty-five chatbots later, I’d hit the same wall enough times to realize it wasn’t a prompt problem. It was a structural problem. The model wants to drift toward its priors, and storing identity inside the model doesn’t hold against that for long. Once I saw the shape of the problem, the fix wasn’t more prompt engineering. It was different architecture.

Along the way I went through a Python prototype, a Rust physics kernel, measurement experiments, and one accidental success: a game companion I wrote in a weekend that held character better than any of the serious builds.

This site is what I wish someone had handed me on day one.

Who this is for

People trying to build something with AI who keep hitting walls they don’t understand. People who’ve used ChatGPT, Claude, Gemini, or Grok and know there’s more going on underneath than the interface lets on. People who suspect the AI hype is mostly marketing and want the part that still survives contact with real systems.

If you’re here for “top 10 prompts that will 10x your productivity,” the door is that way. If you want to know why your chatbot forgets who it is, why your agent refuses to do the obvious thing, or whether you should run AI locally or in the cloud, keep reading.

What’s here

Failure case studies, mostly. Real projects, what I tried, why they broke, and what held up. Beginner explainers for agents, RAG, local models, and fine-tuning, in language that doesn’t assume a PhD. Honest tool comparisons without affiliate-link brain rot. And a small set of laws I keep running into across my AI projects, written down so I stop having to relearn them.

What’s not here

Breathless hype. Hot takes on which startup raised money. “X tool will replace Y job” predictions, because I don’t know, you don’t know, and I don’t think anyone selling predictions can tell you for sure either. No course upsells. If I ever sell something it’ll be because I built it and it works, not because I trained a funnel.

Get in touch

If you’ve hit a problem I’ve written about and want to compare notes, or if you’ve got a failure story worth adding to the archive, email me at hello@echonet-ai.com. I read everything. Replies are slower than email from an actual company but faster than you might expect from one person running this alone.

Corrections

I try to keep factual claims on this site grounded in my own testing, project records, or cited sources. If you spot a factual mistake, missing attribution, or outdated claim, email hello@echonet-ai.com with the page URL and the correction. I review corrections manually and update the page when the evidence supports it.
