🚀 Getting Started

Prerequisites

Before you begin, ensure you have the following installed:

  • Node.js 18.x or higher
  • npm, yarn, or pnpm package manager
  • PostgreSQL database
  • Google Client ID and Secret (for authentication)
  • Optional provider keys depending on the features you want to use:
    • OpenAI API key (for cloud text generation)
    • Together AI API key (for image generation)
    • FAL API key (for additional image generation flows)
    • Tavily API key (for web search)
    • Unsplash access key (for stock images)

Installation

  1. Clone the repository

    git clone git@github.com:allweonedev/presentation-ai.git
cd presentation-ai

  2. Install dependencies

    pnpm install

  3. Set up environment variables

    Create a .env file in the root directory with the following variables:

    # Database
DATABASE_URL="postgresql://username:password@localhost:5432/presentation_ai"

# Authentication
NEXTAUTH_SECRET=""
NEXTAUTH_URL="http://localhost:3000"

# Google OAuth Provider
GOOGLE_CLIENT_ID=""
GOOGLE_CLIENT_SECRET=""

# AI Providers
OPENAI_API_KEY=""
TOGETHER_AI_API_KEY=""
FAL_API_KEY=""

# File Upload Service
UPLOADTHING_TOKEN=""

# Optional search and media providers
UNSPLASH_ACCESS_KEY=""
TAVILY_API_KEY=""

    💡 Tip: Copy .env.example to .env and fill in your actual values. If you plan to use local text models through Ollama or LM Studio, you can run text generation without an OPENAI_API_KEY.

Database Setup

  1. Initialize the database

    pnpm db:push

  2. Start the development server

    pnpm dev

  3. Open the application

    Navigate to http://localhost:3000 in your browser.

🧠 Local Models Guide

ALLWEONE Presentation AI now supports both Ollama and LM Studio as local model providers.

LM Studio

  1. Install LM Studio.
  2. In the LM Studio app, turn the Server ON and enable CORS.
  3. Download any model you want to use inside LM Studio.

Ollama

  1. Install Ollama.
  2. Download whichever model you want to use (for example: ollama pull llama3.1).

Using Local Models in the App

  1. Open the app and open the text model selector.
  2. Choose the model you want to use.
  3. For LM Studio, load the model in LM Studio first.
  4. For Ollama, installed models appear automatically, and some recommended models can be downloaded on first use.
  5. Enjoy the generation.

Notes:

  • OpenAI remains available as the default cloud text model.
  • Models will automatically appear in the Model Selector when the LM Studio server or the Ollama daemon is running.
  • Make sure LM Studio has CORS enabled so the browser can connect.
