Top AI Product

There’s a moment most of us have experienced: you’re about to type something personal into ChatGPT or Claude, and you pause. Maybe it’s a health question, a private journal entry, or a half-baked business idea you’re not ready to share with anyone. That little hesitation — knowing your words are about to land on someone else’s servers — is exactly what pushed developer Ali Chherawalla to build [Off Grid](https://github.com/alichherawalla/off-grid-mobile).

Off Grid is an open-source mobile app that packs text generation, image generation, vision, voice transcription, and document analysis into a single package, and it all runs locally on your phone. No cloud calls, no API keys, no data leaving your device. Ever. Think of it as a Swiss Army Knife for on-device AI. It supports popular models like Qwen 3, Llama 3.2, Gemma 3, and Phi-4, plus any GGUF model you want to throw at it. On a decent flagship phone, you’re looking at 15-30 tokens per second for text, and the on-device Stable Diffusion image generation — which taps into NPU acceleration on Snapdragon chips — cranks out images in about 5 to 10 seconds. That’s genuinely usable.

The app clearly struck a nerve. When Chherawalla first [posted it on Hacker News](https://news.ycombinator.com/item?id=47019133), it shot to the number one spot. The [GitHub repo](https://github.com/alichherawalla/off-grid-mobile) racked up 425+ stars quickly, and a Reddit thread pulled in over 150,000 views. A [second Show HN](https://news.ycombinator.com/item?id=47142003) followed shortly after, showcasing new features like offline tool calling, web search, and a calculator — all running without connectivity. Chherawalla also wrote a great [behind-the-scenes post on DEV Community](https://dev.to/alichherawalla/from-personal-frustration-to-1-on-hacker-news-how-i-built-off-grid-and-hit-425-stars-4989) about the journey from personal frustration to viral launch.

What really resonates, though, is the feedback from users. One Hacker News commenter nailed it: “The privacy angle is the real killer feature here… people self-censor because it goes to a server somewhere.” That’s the whole point. When the privacy concern disappears, people actually use AI differently — more honestly, more creatively, more freely. Off Grid is currently available on Android (grab the APK from the GitHub releases), with iOS on the way. If you’ve ever wanted to tinker with AI on a flight, in a remote area, or just without the surveillance tax, this one’s worth a look.
