Your phone has a GPU more powerful than most 2018 laptops. Right now it sits idle while you pay monthly subscriptions to run AI on someone else's server, sending your conversations, your photos, your voice to companies whose privacy policy you've never read. Off Grid is an open-source app that puts that hardware to work. Text generation, image generation, vision AI, voice transcription — all running on your phone, all offline, nothing ever uploaded.

That means you can use AI on a flight with no wifi. In a country with internet censorship. In a hospital where cloud services are a compliance nightmare. Or just because you'd rather not have your journal entries sitting in someone's training data.

The tech: llama.cpp for text (15-30 tok/s, any GGUF model), Stable Diffusion for images (5-10s on Snapdragon NPU), Whisper for voice, SmolVLM/Qwen3-VL for vision. Hardware-accelerated on both Android (QNN, OpenCL) and iOS (Core ML, ANE, Metal).

MIT licensed. Android APK on GitHub Releases. Build from source for iOS.

I like it, I have a couple minor things (android)

Markdown rendering would be great Letting me download a model, wait for it, then. tell me I can't run it safely in my ram feels like it could've told me at the beginning

Bar that nice! Was it annoying integrating with apples AI stuff?

hey! thank you for the feedback. appreciate it. I pushed something recently that actually prevents showing up models in the download screen that don't fit on your phone. Please give it a whirl.

Yeah it wasn't straight forward figuring out the speed + getting it to work for both Android and iOS. Fair bit if complexity. But I'm so happy I got it done.

Looks useful, though something went wrong doing NPU image generation on my phone.

Reminds me a lot of https://github.com/google-ai-edge/gallery which is a proof-of-concept app by Google themselves for their AI libraries. However, your app supports more and larger models without having to manually import anything, which is very useful.

i don't think they do image gen etc? You can almost think of Off Grid like an on-device assistant. It'll handle everything like vision, and attachments too. We're still early stages and lots of optimizations to do, but we'll get there.

Putting the power and the data of the users in the hands of the users themselves! Well done. Getting it setup was easy. Wish the app recognized the keyboard and realized when it was displayed so the bottom menu and chat box weren't hidden under it.

On my Samsung phone it doesn't move the screen up to make room for the keyboard so I can't see what I'm typing.

Really awesome idea though. I want this to work.

Is there something similar, but geared towards a Linux desktop / laptop? I suppose this would be relatively easy to adapt.

If you have enough (V)RAM you can set up Ollama + any of the generation tools here (https://docs.openwebui.com/category/create--edit-images) and hook them into OpenWebUI to get something pretty close to what you'd get on a cloud AI chatbox.

Decently performing models for day to day use cases use at least 6GB VRAM each, though, and even then they're not coming very close to what the cheapest AI websites offer.

The repository is listed as offgrid-mobile everywhere on that page but is off-grid-mobile.

So the lastest releases is at https://github.com/alichherawalla/off-grid-mobile/releases/l...

And the clone would be: git clone https://github.com/alichherawalla/off-grid-mobile.git

Looks like the build requirements for SDK and NDK in the build instructions don't match the build.gradle.

-Android SDK (API 34)

-Android NDK r26

vs

compileSdkVersion = 36

targetSdkVersion = 36

ndkVersion = "27.1.12297006"

Game-changer.Just downloaded it and wow,this is the future. It’s incredible to have this much power fully offline. No lag, no privacy concerns, just pure utility. I’ve been playing with the vision AI all morning and it hasn't crashed once. 10/10. I have also used other GitHub projects but this feels premium, faster and optimised. Thank you for this!

Nice idea, but isnt this kind of daft?

There are basically no useful models that run on phone hardware.

> Results vary by model size and quantization.

I bet they do.

Look, if you cant run models on your desktop, theres no way in hell they run on your phone.

The problem with all of these self hosting solutions is that the actual models you can run on them aren't any good.

Not like, “chat gpt a year ago” not good.

Like, “its a potato pop pop” no good.

Unsloth has a good guide on running qwen3 (1), and the tldr is basically, its not really good unless you run a big version.

The iphone 17 pro has 12GB of ram.

That is, to be fair, enough to run some small stable diffusion models, but it isnt enough to run run a decent quant of qwen3.

You need about 64 GB for that.

So… i dunno. This feels like a bunch of empty promises; yes, technically it can run some models, but how useful is it actually?

Self hosting needs next gen hardware.

This gen of desktop hardware isnt good enough, even remotely, to compare to server api options.

Running on mobile devices is probably still a way away.

Yeah. The solution if you want to have your own AI is to put a box online or rent cloud inference, and access it over a browser or a phone app.

We have on-prem AI for my microgrid community, but it’s a nascent effort and we can only run <100b models. At least that size is extremely useful for most stuff, and we have a selection of models to choose from on openAI /ollama compatible API endpoints.

I'm surprised Apple is still cheaping out on RAM on their phones, especially with the effort they've been putting into running AI locally and all of their NPU marketing.

with the metal infra its actually quite good. Agreed you can't run really large models, but inference is very fast and TTFT is very low. It's a beautiful experience

The app is basically just a wrapper that makes it super easy to set this up, which I'm very thankful for. I sometimes want to toy with this stuff but the amount of tinkering and gluing things together needed to just get a chat going is always too much for me. The fact that the quality of the AI isn't good is just the models not being quite there yet. If the models get better, this app will be killer.

If there's a similar app for desktop that can set up the stronger models for me, I'd love to hear about it.

Any random thing might happen in the future.

That doesnt have any bearing on how useful this is right now.

All we can do is judge right now how this compares to what it promises.

LM Studio does it well. Along with being a system integrator for SD, and text models I've tried to create a very good chat experience. So theres some sauce over there with Prompt enhancements, Auto detection of images, English Transcription suppor, etc

I think if people will people know how accessible it is to run local LLMs on their device they will consider buying devices with more memory that will be able to run better models. Local LLMs in the long run are game changers

I actually think you should give it a spin. IMO you don't need claude level performance for a lot of day to day tasks. Qwen3 8B, or even 4B quantized is actually quite good. Take a look at it. You can offload to the GPU as well so it should really help with speed. Theres a setting for it

No, it’s not.

Trust me, I don't write this from a position of vague hand waving.

Ive tried a lot of self hosted models at a lot of sizes; those small models are not good enough, and do not have a context long enough to be useful for most everyday operations.

It seems like a good solution for those living under a regime that sensors communication, free information flow, and LLM usage. Especially with a model that contains useful information.

This is genuinely exciting. The fact that you're getting 15-30 tok/s for text gen on phone hardware is wild — that's basically usable for real conversations.

Curious about a couple things: what GGUF model sizes are practical on a mid-range phone (say 8GB RAM)? And how's the battery impact during sustained inference — does it drain noticeably faster than, say, a video call?

The privacy angle is the real killer feature here IMO. There are so many use cases (journaling, health tracking, sensitive work notes) where people self-censor because they know it's going to a server somewhere. Removing that barrier entirely changes what people are willing to use AI for.

This sounds exactly like Claude wrote it. I've noticed Claude saying "genuinely" a lot lately, and the "real killer feature" segue just feels like Claude being asked to review something.

I've added a section for recommended models. So basically you can chose from there.

I'd recommend going for any quantized 1B parameter model. So you can look at llama 3.2 1B, gemma3 1B, qwen3 VL 2B (if you'd like vision)

Appreciate the kind words!

That's using the word "real" very loosely.
