Useful for my travels

I travel for work. This app helps in areas where I don’t have service. I can build useful ai models. If you use chat gpt or Claude, you are a loser, in my humble opinion.

Best local AI on the market

Loci is exactly what I have been looking for - it lets me use AI offline, free, and without any limits, and it’s the only option I’ve found that actually works. For anyone else who has been disappointed by other local AI options, I highly recommend this one. Exceeded my expectations significantly.

Great App for Local AI

Great for offline use and data security. Really excited for small model improvement!

Lovely concept

For a free and offline app it has a pleasant user experience and clean interface. The tradeoff you make for having less capable models is worth it while traveling or needing offline access. Highly recommend!

Useful and sustainable

Great idea to have models locally where impact can be minimized and privacy is maximized. Looking forward to seeing where this goes
