                ##### Quick Start: Just click on the appropriate tab for what you're trying to do and fill in the required fields. Click "Process <video/audio/article/etc>" and wait for the results.
                #### Simple Instructions
                - Basic Usage:
                    - If you don't have an API key/don't know what an LLM is/don't know what an API key is, please look further down the page for information on getting started.
                    - If you want summaries/chat with an LLM, you'll need:
                        1. An API key for the LLM API service you want to use, or,
                        2. A local inference server running an LLM (like llamafile-server/llama.cpp - for instructions on how to do so see the projects README or below), or,
                        3. A "local" inference server you have access to running an LLM.
                    - If you just want transcriptions you can ignore the above.
                    - Select the tab for the task you want to perform
                    - Fill in the required fields
                    - Click the "Process" button
                    - Wait for the results to appear
                    - Download the results if needed
                    - Repeat as needed
                    - As of writing this, the UI is still a work in progress.
                    - That being said, I plan to replace it all eventually. In the meantime, please have patience.
                    - The UI is divided into tabs for different tasks.
                    - Each tab has a set of fields that you can fill in to perform the task.
                    - Some fields are mandatory, some are optional.
                    - The fields are mostly self-explanatory, but I will try to add more detailed instructions as I go.
                #### Detailed Usage:
                - There are 8 Top-level tabs in the UI. Each tab has a specific set of tasks that you can perform by selecting one of the 'sub-tabs' made available by clicking on the top tab.
                - The tabs are as follows:
                    1. Transcription / Summarization / Ingestion - This tab is for processing videos, audio files, articles, books, and PDFs/office docs.
                    2. Search / Detailed View - This tab is for searching and displaying content from the database. You can also view detailed information about the selected item.
                    3. Chat with an LLM - This tab is for chatting with an LLM to generate content based on the selected item and prompts.
                    4. Edit Existing Items - This tab is for editing existing items in the database (Prompts + ingested items).
                    5. Writing Tools - This tab is for using various writing tools like Grammar & Style check, Tone Analyzer & Editor, etc.
                    6. Keywords - This tab is for managing keywords for content search and display.
                    7. Import/Export - This tab is for importing notes from Obsidian and exporting keywords/items to markdown/CSV.
                    8. Utilities - This tab contains some random utilities that I thought might be useful.
                - Each sub-tab is responsible for that set of functionality. This is reflected in the codebase as well, where I have split the functionality into separate files for each tab/larger goal.

            #### Its ok, you're not alone, most people have no clue what any of this stuff is.
            - So let's try and fix that.

            #### Introduction to LLMs:
            - Non-Technical introduction to Generative AI and LLMs: https://paruir.medium.com/understanding-generative-ai-and-llms-a-non-technical-overview-part-1-788c0eb0dd64

            #### Various Phrases & Terms to know
            - **LLM** - Large Language Model - A type of neural network that can generate human-like text.
            - **API** - Application Programming Interface - A set of rules and protocols that allows one software application to communicate with another.
                * Think of it like a post address for a piece of software. You can send messages to and from it.
            - **API Key** - A unique identifier that is used to authenticate a user, developer, or calling program to an API.
                * Like the key to a post office box. You need it to access the contents.
            - **GUI** - Graphical User Interface - the thing facilitating your interact with this application.
            - **DB** - Database
            - **Prompt Engineering** - The process of designing prompts that are used to guide the output of a language model. Is a meme but also very much not.
            - **Quantization** - The process of converting a continuous range of values into a finite range of discrete values.

                #### Great, glad you asked! Getting Started:
                - **Getting an API key for a commercial services provider:
                    - **OpenAI:**
                        * https://platform.openai.com/docs/quickstart
                    - **Anthropic:**
                        * https://docs.anthropic.com/en/api/getting-started
                    - **Cohere:**
                        * https://docs.cohere.com/
                        * They offer 1k free requests a month(up to 1million tokens total I think?), so you can try it out without paying.
                    - **Groq:**
                        * https://console.groq.com/keys
                        * Offer an account with free credits to try out their service. No idea how much you get.
                    - **DeepSeek:**
                        * https://platform.deepseek.com/ (Chinese-hosted/is in english)
                    - **OpenRouter:**
                        * https://openrouter.ai/
                    - **Mistral:**
                        * https://console.mistral.ai/
                - **Choosing a Model to download**
                    - You'll first need to select a model you want to use with the server.
                        - Keep in mind that the model you select will determine the quality of the output you get, and that models run fastest when offloaded fully to your GPU.
                        * So this means that you can run a large model (Command-R) on CPU+System RAM, but you're gonna see a massive performance hit. Not saying its unusable, but it's not ideal.
                        * With that in mind, I would recommend an abliterated version of Meta's Llama3.1 model for most tasks. (Abliterated since it won't refuse requests)
                        * I say this because of the general quality of the model + it's context size.
                        * You can find the model here: https://huggingface.co/mlabonne/Meta-Llama-3.1-8B-Instruct-abliterated-GGUF
                        * And the Q8 quant(total size 8.6GB): https://huggingface.co/mlabonne/Meta-Llama-3.1-8B-Instruct-abliterated-GGUF/resolve/main/meta-llama-3.1-8b-instruct-abliterated.Q8_0.gguf?download=true
                - **Local Inference Server:**
                    - **Llamafile-Server (wrapper for llama.cpp):**
                        * Run this script with the `--local_llm` argument next time, and you'll be walked through setting up a local instance of llamafile-server.
                    - **Llama.cpp Inference Engine:**
                        * Download the latest release for your platform here: https://github.com/ggerganov/llama.cpp/releases
                        * Windows: `llama-<release_number>-bin-win-cuda-cu<11.7.1 or 12.2.0 - version depends on installed cuda>-x64.zip`
                            * Run it: `llama-server.exe --model <path_to_model> -ctx 8192 -ngl 999`
                                - `-ctx 8192` sets the context size to 8192 tokens, `-ngl 999` sets the number of layers to offload to the GPU to 999. (essentially ensuring we only use our GPU and not CPU for processing)
                        * Macos: `llama-<release_number>-bin-macos-arm64.zip - for Apple Silicon / `llama-<release_number>-bin-macos-x64.zip` - for Intel Macs
                            * Run it: `llama-server --model <path_to_model> -ctx 8192 -ngl 999`
                                - `-ctx 8192` sets the context size to 8192 tokens, `-ngl 999` sets the number of layers to offload to the GPU to 999. (essentially ensuring we only use our GPU and not CPU for processing)
                        * Linux: You can probably figure it out.
                    - **Kobold.cpp Server:**
                        1. Download from here: https://github.com/LostRuins/koboldcpp/releases/latest
                        2. `Double click KoboldCPP.exe and select model OR run "KoboldCPP.exe --help" in CMD prompt to get command line arguments for more control.`
                        3. `Generally you don't have to change much besides the Presets and GPU Layers. Run with CuBLAS or CLBlast for GPU acceleration.`
                        4. `Select your GGUF or GGML model you downloaded earlier, and connect to the displayed URL once it finishes loading.`
                    - **Linux**
                        1. `On Linux, we provide a koboldcpp-linux-x64 PyInstaller prebuilt binary on the releases page for modern systems. Simply download and run the binary.`
                            * Alternatively, you can also install koboldcpp to the current directory by running the following terminal command: `curl -fLo koboldcpp https://github.com/LostRuins/koboldcpp/releases/latest/download/koboldcpp-linux-x64 && chmod +x koboldcpp`
                        2. When you can't use the precompiled binary directly, we provide an automated build script which uses conda to obtain all dependencies, and generates (from source) a ready-to-use a pyinstaller binary for linux users. Simply execute the build script with `./koboldcpp.sh dist` and run the generated binary.
