Steal the Plug-and-Play n8n RAG Agent That Never Forgets
Free n8n RAG Agent Template: Build a Supabase AI Brain with Zep Memory & Cohere Rerank

TL;DR: You’re 17 minutes away from “I told you three times already - I make candles!” to “Shut up and make me money.” It’s time to crack open the Yeti and take a bite of that Tuna wrap, let’s get into it. Template link at the bottom.
Pre-requisites:
Subscribe to the newsletter (Free)
Set up n8n self-hosted plan or paid plan. (You’re on your own, pal!)
Want to automated workflows and AI agents in n8n even faster than having Claude build them?
Download this one right now for free! The catch? Subscribe, and it’s yours. Here’s why you should care: you’ll get access to the most advanced RAG based research Agent on the internet. Don’t believe me? Download it for free and see for yourself.
The Diagnosis: Your Current RAG Flow Was Found Dead In The Wrong Recycle Bin
Here’s the problem: Pop open YouTube right now and you might see a common theme: “This AI Agent Runs My Life and Makes Me Billion$.” Come to find out, it’s an email agent that has no real world value or a knowledge base agent that chunks content like a virtual wood chipper.
You feel left behind, you feel like you’re missing out, and you feel out of touch with the cutting edge of AI. The “gurus” are so far ahead of me, why bother… No more, I say!
You don’t need another email agent that you don’t trust to send emails to real people - you need AI that actually works for you and your business ventures, whether those ventures exist already or you’re just getting started. This is for you!
Just pay for n8n (somehow), subscribe to this newsletter - again, it’s free - and that’s all you need, my friend!

Why This Agent Would Have 6 Rings If It had Fingers
1. Zep – Persistent Memory
Tech: Zep vector-aware conversation storage (this is the cutting edge and beasts Mem0)
The Proof?: Up to 100 percent accuracy gains while slashing latency by 90 percent. (blog.getzep.com)
What It Feels Like: Siri, but it remembers your wife’s birthday, the special type of breakfast salami you like, and the fact you detest the word “webinar.”
2. Context-Preserving Smart Chunking
No random sentence beheadings. Our JavaScript splitter hugs sentence boundaries, sprinkles a 10 percent overlap, and tags every chunk with sentiment, keywords, and a relevance score. Check the logs if you don’t believe me - the difference is night and day.
3. Supabase – pgvector 0.6 Parallel Indexing
Parallel HNSW builds are 30× faster than the single-thread yesteryear approach. Hold my beer.
Old way: 15 minutes to ingest 10k pages.
New way: Blink, “Ok - pass me my beer back,” done.
4. Cohere Rerank 3 – The Bouncer at the Club
Out-scores larger models on ranking quality while being 90-98 percent cheaper to run.
Your AI stops serving random Wikipedia salad and starts serving steak.
5. Multi-Agent Research Swarm
A RAG is useless without context to fill it with. No dice! I built you a full research agent ensemble that connects directly with your RAG agent to fill it with as much context as you desire. You get it all, because - why settle for less?
6. Get All My Prompts
Just want to know prompts I used to make this all possible? Go figure, they’re all in there! No secrets withheld, friends!
Showdown: n8n Basic RAG Template vs. My RAG
Feature | Stock n8n Flow | Distortion-RAG |
|---|---|---|
Memory | Clears on tab close | Writes everything to Zep, retrieves in < 100 ms |
Chunking | “Pretty sure sentences are optional.” | Token-aware, overlap, metadata - chef’s kiss! |
Indexing | Serial, get Wordle ready | Parallel, 30× faster |
Ranking | Cosine ≈ “kinda close” | Cohere Rerank 3 vetting every chunk |
Research | Zero | Perplexity, Reddit, Wikipedia tag-team |
Real-World Wins
Course creator: Perform deep research to create curriculum in concert with real market insights from Reddit on your ICP (Ideal Customer Profile).
SaaS founder: Reddit agent surfaces buyer psychology better than a $6k / mo. copywriter.
Some “Consultant”: “This rules!” I made this up - but I’m convinced that’s what they’d definitely say.

Your Fork In The Road
Option A: Keep hand-holding amnesiac chatbots and re-explaining your business every 20 minutes.
Option B: Click once, get an AI librarian who never forgets, indexes faster than rumors about your morning salami cravings, and writes like it majored in persuasion.
I’d pick B, but I’m just a tad biased.
