Locally Uncensored vs Jan.ai
Jan.ai has earned a reputation as one of the most polished, ChatGPT-like interfaces among local AI apps. Built on Electron with a clean design, it supports both local models and cloud APIs from providers like OpenAI, Anthropic, and Google. For users who want a single chat interface that bridges local and cloud AI, Jan is an appealing option.
Locally Uncensored takes a fundamentally different approach. Rather than trying to be a universal chat client, it focuses on being a complete local AI creative suite. It combines LLM chat via Ollama with image generation and video generation via ComfyUI -- capabilities that Jan does not offer at all. If you are exploring the best local AI apps in 2026, these two represent very different philosophies about what a local AI app should be.
Both apps run on Windows, macOS, and Linux. Both let you chat with local models on your own hardware. But the similarities end there. This comparison breaks down exactly where each app excels and where it falls short.
Feature Comparison
| Feature | Locally Uncensored | Jan.ai |
|---|---|---|
| LLM Chat | Yes (Ollama) | Yes (Cortex/llama.cpp) |
| Image Generation | Yes (ComfyUI) | No |
| Video Generation | Yes (ComfyUI) | No |
| Cloud API Support | No (local only) | Yes (OpenAI, Anthropic, etc.) |
| Custom Personas | 25+ built-in | No |
| Extension System | No | Yes |
| Uncensored by Default | Yes | No |
| License | MIT | AGPL v3 |
| UI Framework | Tauri (Rust) | Electron (Chromium) |
| App Memory Usage | Low (50-100 MB) | High (300-500 MB) |
| HuggingFace Browser | No | Yes |
| Model Management | Built-in (Ollama) | Built-in + HF |
| Docker Required | No | No |
Where Locally Uncensored Wins
- Image and Video Generation -- This is the single biggest differentiator. Locally Uncensored integrates ComfyUI for full image generation (Stable Diffusion XL, FLUX.1 Schnell, Pony Diffusion, Juggernaut XL) and video generation (Wan 2.1, AnimateDiff). Jan has no visual generation capabilities whatsoever. If you need anything beyond text chat, this alone justifies the switch.
- Lightweight Runtime -- Locally Uncensored is built with Tauri, which uses Rust and your system's native webview. This typically means 50-100 MB of RAM for the app shell. Jan uses Electron, which bundles an entire Chromium browser and routinely consumes 300-500 MB before you even load a model. On machines with limited RAM, that difference matters for model inference headroom. This is similar to the advantage over other Electron-based apps like LM Studio.
- MIT License -- Locally Uncensored uses the permissive MIT license. Jan uses AGPL v3, which requires you to share source code of any modifications and has stricter redistribution terms. For developers building on top of these tools, the MIT license offers significantly more freedom.
- Custom Personas -- 25+ built-in AI personas let you switch between different personalities instantly without writing system prompts. Jan provides a blank chat window with no persona system.
- Uncensored by Default -- Ships with abliterated model recommendations and no content filters on text, images, or video. Jan does not specifically cater to uncensored use cases.
Where Jan.ai Wins
- Cloud API Support -- Jan connects to OpenAI, Anthropic, Google, Mistral, and other cloud providers alongside local models. If you want a single interface for both local and cloud AI, Jan is one of the few apps that does this well. Locally Uncensored is purely local by design.
- Polished Chat Interface -- Jan has one of the cleanest, most intuitive chat UIs among local AI apps. It genuinely feels like a local version of ChatGPT. The conversation management, threading, and overall design are excellent.
- Extension System -- Jan supports a plugin architecture that lets the community build and install extensions for additional functionality. Locally Uncensored does not currently have an extension system.
- HuggingFace Integration -- Browse, search, and download models directly from HuggingFace within Jan. You can filter by quantization level and see model sizes before downloading. Locally Uncensored handles model management through Ollama's built-in model library.
- Self-Contained Inference -- Jan bundles its own inference engine via Cortex, so it does not depend on an external process like Ollama. Locally Uncensored requires Ollama to be installed and running for text chat.
Architecture Differences
The architectural differences between these two apps reflect their different priorities. Jan is built with Electron and ships with its own Cortex inference engine based on llama.cpp. This makes it a self-contained package, but the Electron runtime adds significant memory overhead.
Locally Uncensored uses Tauri (Rust backend with native system webview) and delegates inference to Ollama for text and ComfyUI for image/video. This modular approach means a lighter app footprint and the ability to leverage each backend's full feature set, but it does require those backends to be installed separately. The setup script automates this process.
For users who already have Ollama installed, Locally Uncensored adds zero redundant inference engines. For users who want everything in one package with no external dependencies, Jan's self-contained approach is more convenient.
The Verdict
Choose Jan.ai if you want a polished ChatGPT-like interface that supports both local models and cloud APIs like OpenAI and Anthropic. Jan is the right choice if text chat is all you need and you value a clean UI with HuggingFace model browsing.
Choose Locally Uncensored if you want a lightweight, fully local AI app with text, image, and video generation capabilities. The MIT license, Tauri runtime, uncensored defaults, and ComfyUI integration make it the better choice for users who want a complete creative AI suite on their own hardware.
Frequently Asked Questions
Is Locally Uncensored better than Jan.ai?
It depends on your priorities. Locally Uncensored is better if you want text chat, image generation, and video generation in one app with a permissive MIT license. Jan.ai is better if you need cloud API support alongside local models and prefer a polished ChatGPT-like interface.
Does Jan.ai support image generation?
No. Jan.ai focuses on text-based LLM chat and cloud API integration. For local image and video generation, you need a tool like Locally Uncensored which integrates ComfyUI for Stable Diffusion, FLUX, and Wan 2.1 support.
Is Jan.ai open source?
Jan.ai is released under the AGPL v3 license, which is open source but has copyleft requirements. Locally Uncensored uses the more permissive MIT license, which allows unrestricted use, modification, and distribution.
Which uses less memory -- Locally Uncensored or Jan?
Locally Uncensored uses Tauri (Rust + system webview) which typically consumes 50-100 MB of RAM for the app shell. Jan uses Electron which bundles a full Chromium instance and often consumes 300-500 MB or more. Actual model inference memory depends on the model size, not the app.
