Nem-0

You: Hello, my name is *** and an I am an AI builder.

Nem-0: Hello ***. What can I help you with today?

You: I am currently struggling with xyz problem in my business. Here are some xyz ideas.

Nem-0: Ok...you're absolutely right...

You: ...

Nem-0 is an AI-powered business advisor agent with long-term memory, built for small business owners who need a knowledgeable, always-available advisor at their side. Unlike typical AI chat tools, Nem-0 remembers everything; your business history, goals, challenges, and decisions are all stored and recalled automatically. No need to re-explain your situation every session. Nem-0 picks up right where you left off.

How its made:

Tech Stack:

• Frontend: Vite + React + Tailwindcss
• Backend: FastAPI + Mem0
• Database: Supabase
• OpenAI API

AI First Development

• Started from Vega as a foundation and extended it into a memory-enabled AI agent
• Referenced Mem0 docs and collaborated with Claude Code to scaffold the FastAPI backend
• Used Bolt.new to rapidly prototype the frontend, choosing Vite + React over Next.js for simplicity
• Added a validation layer to guard against prompt injection and SQL injection, since the LLM is directly connected to a database

Optimizations

• Add authentication so the app can be deployed for multiple users in a production environment. Currently each user clones the repo and uses their own keys.
• Build a session/folder system to organize and revisit past conversations.
• Explore Mem0's managed cloud mode as an alternative to self-hosting memory on Supabase, to reduce infrastructure overhead.

Lessons Learned

• Running the FastAPI backend and Vite frontend concurrently with concurrently (via a single npm run dev command) significantly improved the development workflow.
• Mem0 in self-hosted mode requires your own LLM and vector store. OpenAI handles embeddings and completions while Supabase stores the vectors. No Mem0 API key needed for this current build.
• Fine-tuning the agent prompt with realistic small business scenarios (cash flow, inventory, revenue goals) was critical to getting useful, grounded responses instead of generic advice.

How to run Nem-0

Prerequisites

• Python 3.10+
• Node.js 18+
• A Supabase project with a Postgres database
• An OpenAI API key

1. Clone the repo

git clone https://github.com/your-username/nem-0.git
cd nem-0

2. Set up environment variables

Create a .env file in the project root:

SUPABASE_URL=your_supabase_project_url
SUPABASE_KEY=your_supabase_anon_or_service_key
DATABASE_URL=your_postgres_connection_string
OPENAI_API_KEY=your_openai_api_key
MODEL_CHOICE=gpt-4o

3. Install backend dependencies

python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

4. Install frontend dependencies

npm install
npm --prefix nem0 install

5. Run the app (frontend + backend concurrently)

npm run dev

This starts:

• FastAPI backend on http://localhost:8000
• Vite + React frontend via npm --prefix nem0 run dev
