1. Chat With Customizable AI Characters On Your PC

An example RP chat with a customized AI character inside the OobaBooga WebUI.
OobaBooga Text Generation WebUI is in my honest opinion one of the best locally hosted alternatives to the well-known character.ai

With the aid of tools such as the OobaBooga Text Generation WebUI, you can easily chat and roleplay with thousands of pre-made AI characters (and make customized ones by yourself), provided you have an average-spec system that can handle it. You just have to try it out if you have already used sites like character.ai.

How is it better from character.ai? Well, while the quality of the models it can run depends solely on your hardware, using the OobaBooga WebUI is 100% private – you don’t share any conversation data with the outside world. Other than that, you can used uncensored models without any filters getting in the way of your RP sessions or AI assistant conversations. This makes it one of the best locally hosted alternatives for character.ai there are!

Moreover, the OobaBooga experience is much more customizable with hundreds of different open-source models available online and the large amount of setting tweaks you can do inside the WebUI. And it’s all available for free!

The best thing about it? I have a full guide on how to install, set up and import your own models and custom characters using this neat piece of software right here: How To Set Up The OobaBooga TextGen WebUI – Full Tutorial

I’m running the software on my pretty dated NVIDIA RTX 2070 Super with the Dolphin-2.1-Mistral-7B-AWQ model, getting generation speeds between 15-20 tokens per second with the right configuration. In practice, this almost matches the ChatGPT client experience!

The whole prep process won’t take you more than 15 minutes. Be sure to try it out!

2. Generate Images With Stable Diffusion

The RVC WebUI and AICoverGen are two of the most popular projects which you can make use of to generate AI vocal covers on your PC.

Another great use of AI tools is live voice changing.

5. Convert Songs To Stems And Separate Acapellas!

The Ultimate Vocal Remover user interface.
The Ultimate Vocal Remover is a free software that can help you convert any song you want into stems, or separate the acapella vocals from the instrumental.

Using the Ultimate Vocal Remover, you can do two fun things. The first one, is splitting any song you throw at it into an acapella and an instrumental track. This means that you can create a karaoke version of any track you can imagine, or get clean vocal parts from most of the music files you have on your system. Neat!

Another great thing this software is capable of is separating songs into individual stem files. What does that mean? Well, imagine you import a song, and after a few minutes of the AI model doing its magic you are presented with 5 separate tracks, one with just the drums, the second one with the vocals, bass guitar, synth and so on! It’s possible with the UVR software, and it’s very useful for me as a music producer to reverse engineer some more complex songs!

Although I don’t have a guide for installing the Ultimate Vocal Remover, there is a reason for that. The installation process is so simple that there is little to no guidance needed there! Just see for yourself – give the official GitHub repository of the UVR software a visit for the short and concise installation instructions!

6. Local ChatGPT-like Experience Without a GPU!

GPT4ALL software chat interface.
With GPT4ALL you can get the local large language model conversation experience literally without having a GPU on your system!

Last things last comes the GPT4ALL software which is pretty similar to the OobaBooga WebUI I’ve already mentioned, but… it doesn’t require a GPU to use!

While the text generation might be a little bit slower with some older processors, this program allows you to use tens of compatible open-source LLM models for local AI assistant conversations on almost every relatively recent average-spec laptop.

If you don’t have a graphics card strong enough (or with enough VRAM) to use it with larger text generation models, you really should give GPT4ALL a try!

Check out my full guide on the GPT4ALL setup here: How To Run Gpt4All Locally For Free – Local GPT-Like LLM Models Quick Guide.
