Prerequisites

To run ToK, you'll need to install two dependencies:

• Ollama: Facilitates easy model downloading, serving, and intelligent device loading. (required)
• Neo4j Desktop: Used for top-tier vector and graph stores. (install if running without docker / with the exe in releases or for research purposes)

Setting Up Neo4j (IF Neo4j Desktop IS INSTALLED)

1. Download and install Neo4j Desktop.
2. Add the Neo4j bin path to your system's PATH environment variable. This allows Neo4j to be accessed by ToK.
   • Example bin path for Windows: \path\to\user\.Neo4jDesktop\relate-data\dbmss\your-current-dbms\bin

• (For Windows) Activate the Neo4j CLI by running the following command in Command Prompt or PowerShell for Windows:

  neo4j windows-service install

Please go through this link to perform the above steps for other arch's (and for reference).

Getting Started

You have two main options to run ToK:

Option 1: Running ToK with Docker (RECOMMENDED)

1. Ensure you have Docker and Docker Compose installed on your machine.
2. Clone the repository:

   git clone https://github.com/gurveervirk/ToK.git

3. Navigate to the directory containing the docker-compose.yml file:

   cd ToK/docker

4. Serve Ollama on your local system. (app may serve it automatically)

   ollama serve

5. Start the application with Docker Compose:

   docker-compose up -d

Option 2: Running ToK Executable (DEPRECATED) (NO LONGER MAINTAINED)

1. Visit the Releases page and download the latest ToK.exe to a location/directory (the app creates necessary files and folders for correct working).

2. Modify the settings by running the app once and clicking the settings icon at the top right hand corner:

   • username: Replace with your Neo4j database username.
   • password: Replace with the password you set in your Neo4j project.
   • uri: Replace with your Neo4j project's URI.

   Note: The default username and URI are the default values for a Neo4j DB. You can also modify it in settings.json, created by the app.

Done! You're now ready to start using ToK.

Usage

After completing the setup:

1. Launch ToK.
2. Choose to either chat directly with the bot or upload documents using the top-right button for enhanced query responses.
3. Enjoy the seamless experience of interacting with a locally-run, AI-powered knowledge assistant that keeps your data private and secure.

Note: On creating a new chat immediately after prompting the LLM / Chat Engine, the latest chat may not be visible in the sidebar along with chatting being unavailable for a few seconds. This may be due to the new chat being stored with an LLM-generated title.
