✨ A Small Update: RAG Pitfalls, Unexpected Endorsement, and That Feeling of Fighting Ghosts with FAISS
Been quietly dealing with some Retrieval-Augmented Generation (RAG) drama lately. You know, the kind where LangChain swears it works but your chunks vanish like they owe the LLM money.
But hey, something cool happened too — got an unexpected endorsement that made all the blood, bugs, and blurry eyes feel worth it.

💥 Surprise: The Creator of Tesseract.js Gave a Shout-Out
Tesseract.js (yeah, the legendary OCR lib with 36K+ GitHub stars) — its creator shared and endorsed my semantic firewall project.
Did I cry? No. But did I walk around the house pretending I was a famous researcher for a full hour? Absolutely.

That moment meant a lot. Not just technically — but philosophically.
I've been obsessed with not just what AI outputs, but why it collapses when semantics go weird.

🧠 What I’ve Learned While Drowning in RAG
Here’s what I’ve noticed helping people on Reddit, StackOverflow, and DEV itself lately:

"Why does my LLM not grab the key info even after chunking everything nicely?"

"Why does RAG return irrelevant docs after I spent 2 hours tuning retrieval?"

"Why do my prompts feel like Vegas dice rolls?"

And honestly?
Most people are debugging vector math when the actual problem is semantic instability. It’s not about what you chunk — it’s about what those chunks mean in context.

So I tried a different approach:

→ Chunks ≠ tokens. I now chunk by semantic tension units (yes, that’s a real thing now).
→ I stopped forcing LangChain routers. Instead, I built semantic alignment guards into the system prompt.
→ I made a tiny “semantic firewall” that prevents prompt poisoning and hallucination loops.

And guess what?
It actually works. Not always perfectly, but good enough to breathe again.

🛠️ If You're Also in RAG Hell, Here's a Free Tool
I open-sourced my full semantic firewall / RAG-enhancement kit here:

MIT license. No signup. Just read the PDF and steal everything.

Tesseract.js’s author literally gave it a signal boost.
It’s starting to get serious downloads and forks — and not just from bots (I hope).

💬 Got RAG Problems? Vent Here. I Might've Seen That Monster Too.
I’m not trying to sell you anything. Just saying:

If your LLM:

hallucinates under pressure,

loses track of your internal docs,

or turns “retrieval” into “random PDF bingo”…

...come drop a comment. Let’s trade scars and fixes.
