The original
GPT4All
A local AI chat app with document chat built in, from Nomic AI. Stable, MIT licensed, but not updated since early 2025.
Replacements
Listings that take over the same core job as GPT4All.
LM Studio
A polished desktop app for downloading, running and chatting with local language models, with an OpenAI-compatible server built in.
LM Studio adds Hugging Face model search, an OpenAI-compatible server and MLX support on Apple Silicon, but it is closed source and cloud features need an account.
Jan
An open-source ChatGPT replacement that runs entirely offline, and can also front cloud providers when you want them.
Jan is Apache 2.0 licensed and developed in the open, runs offline, and can also connect to cloud providers like OpenAI and Anthropic, though it is still pre-1.0.
AnythingLLM
A desktop AI app that answers questions about your own documents, with no account and no API key needed.
AnythingLLM matches GPT4All's document chat with a built-in vector database and separate workspaces per document set, and it can use cloud provider keys if preferred.
Ollama
The simplest way to pull down an open language model and run it on your own machine, from one command or a desktop app.
Ollama runs models from one command or a desktop app and exposes a localhost REST API, but document chat like LocalDocs needs a separate front end.
Msty
Desktop workspace for chatting with local and hosted AI models in one place.
Msty keeps chats, prompt libraries and knowledge bases in one desktop app for local and hosted models, but it is closed source with paid workspace features.
TextGen
Chat with local language models using the TextGen desktop interface.
TextGen offers local chat with text, vision and API access in portable builds under AGPL-3.0, without GPT4All's built-in LocalDocs feature for folder document chat.
KoboldCpp
A single executable that runs GGUF language models locally, with a web interface and no installation at all.
KoboldCpp is a single AGPL-licensed executable that runs GGUF models with CPU or GPU offload, but you download model files yourself and its interface is denser.
Open WebUI
A self-hosted chat interface that talks to Ollama and any OpenAI-compatible API, so your local models get a proper front end.
Open WebUI provides document upload and retrieval with multi-user roles, but it is a self-hosted server you run yourself and needs Ollama or an OpenAI-compatible backend.
Also worth comparing
These listings name GPT4All as their own alternative, so the relationship runs both ways.
llamafile
Packages a language model and the code to run it into one executable file that works on several operating systems without installation.
GPT4All is an MIT-licensed installed chat app with LocalDocs for offline document questions on CPU, but it has not been updated since February 2025.
Open Notebook
Self-hosted, open source alternative to Google's NotebookLM.
GPT4All answers questions from local files with LocalDocs as a desktop app running on CPU, but it has not been updated since February 2025.
