Which one is for you
Pick GPT4All if
- Fits if you want chats and documents to stay on your own machine
- Works for tinkerers who like an API server and Python SDK
Look elsewhere if
- Skip it if you want a phone app: only Mac, Windows and Linux are listed
- Tight if your computer is old: models are large downloads
- Watch out: Nomic's site now centres on a product for architecture and construction firms
- Watch out: the docs we read carry a 2024 copyright notice
Pick Jan if
- Fits if you want open models running on your own computer, with no account and no internet
- Works for developers who want a local OpenAI-compatible endpoint for their other tools
Look elsewhere if
- Skip it if you want it on your phone or in a browser, because it's desktop only
- Tight if your computer is short on memory: Jan's Mac guide suggests 16GB of RAM for 7B models and 32GB for 13B
- Not for you if you have an Intel-based Mac, which isn't supported
- Watch out: cloud models need your own key from each provider, and that provider sees the messages you send
- Too light for images or voice, and Cowork, Jan Agent and memory are previews or still to come
How we grade them
| 2.8GPAGPT4AllGood | 3.0GPAJanVery good | |
|---|---|---|
| Value for money | AA desktop program anyone can download and run, with no paid tier listed. The free listing rests on there being no price on the pages. | AIt costs nothing. Jan is free and open source under Apache 2.0, with no paid plan and no account. The only bills come from cloud providers, and only if you choose to connect one with your own API key. |
| Free plan and trial | AFree outright: nothing to pay to run models locally. | AThe full desktop app is free: local models, cloud connections, web search and the local API server. Nothing is held back, because there's no paid tier to hold it for. |
| Features | CLocal chat, LocalDocs, a model library, an API server and a Python SDK. The documentation is dated 2024, and it does less than cloud assistants. | CIt does the run-models-on-your-own-computer job fully, with projects, assistants, web search and an OpenAI-compatible server. A smaller job than a general assistant, though: no image generation, no voice, and Cowork and memory are nightly-build previews. |
| Ease of use | CNo store rating on record. You download large models, such as a 4.66GB one in the SDK example, and your hardware sets the speed. | BInstall it, pick a model, chat. The Hub shows whether each model fits your hardware, and local ones need no account or key. There's no rating on record for a desktop app, so we go by the listing. |
| Platforms and integrations | CMac, Windows and Linux, which is computers only. It has an API server and Python SDK, and LocalDocs works with Obsidian and OneDrive. | CmacOS, Windows and Linux only, not Intel-based Macs, and no phone or web version at all. It connects to OpenAI, Anthropic, Gemini, Mistral AI, Groq and OpenRouter by key, and its local server feeds tools such as Claude Code. |
| Best for | private chat with models on your own computer | running open AI models on your own computer, free |

Worth knowing
GPT4All
- Models are large downloads; the SDK example loads a 4.66GB model.
- Nomic's site now centers on its Nomic Platform for architecture and construction firms, with GPT4All as a sub-page.
- The documentation we read carries a 2024 copyright notice.
- The pages do not state a price outright; the free listing rests on the absence of any paid tier.
Jan
- Desktop only, on macOS, Windows and Linux. Intel-based Macs are not supported.
- Local models need memory: Jan's Mac guide suggests 8GB of RAM for 3B models, 16GB for 7B models and 32GB for 13B models.
- Cloud models need your own API key from each provider, and those providers see the messages you send them.
- Cowork and the standalone Jan Agent are previews on nightly builds, and the memory feature is marked as coming soon.
Key features
GPT4All
- Local chat
- Models run on your own computer, and the vendor says no cloud is required and no data leaves the machine.
- LocalDocs
- Point the app at local files and chat with them. The docs include guides for Excel, Google Drive, Obsidian and OneDrive.
- Model library
- Browse and download models from inside the app. The quickstart suggests starting with Llama 3.
- API server
- The documentation covers a GPT4All API server so other programs on your machine can talk to a loaded model.
- Python SDK
- Install it with pip and load a model in code, using the llama.cpp backend, for scripts and small applications.
Jan
- Local models
- Downloads and runs open models such as Llama, Gemma and Qwen from Hugging Face using llama.cpp or MLX. The Hub shows whether each model fits your hardware.
- Cloud providers with your own key
- Connects to OpenAI, Anthropic, Gemini, Mistral AI, Groq, OpenRouter and Azure OpenAI, or to any OpenAI- or Anthropic-compatible endpoint, using an API key you supply.
- Built-in web search
- Web search and page fetch tools are on by default for models that support tool use. They run through a keyless Exa endpoint, so no API key or MCP server is needed.
- Projects and assistants
- Projects group conversations under shared instructions and files, and custom assistants keep their own instructions for recurring kinds of work.
- Local API server
- A built-in OpenAI-compatible server at localhost:1337 lets other applications use the models running in Jan, and Claude Code can be set to use them as its backend.
- MCP connectors and Cowork preview
- MCP servers add tools such as code execution and databases. Cowork, which works through multi-step tasks on files and commands, ships only in nightly builds as a preview.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
