Offlex FAQs
Is Offlex really free?
Yes. Offlex has no subscriptions and no paywalls, and it uses open-source models that you choose and download yourself.
Does Offlex work without internet?
Yes. You only need a connection to download a model. After that, all AI processing happens on your phone, so you can chat with no internet at all.
Are my chats private?
Yes. Conversations are stored only on your device. Offlex has no backend servers, accounts, analytics or trackers, so we never see what you write.
Where do the AI models come from?
Offlex downloads open-source language models from public repositories such as Hugging Face. You pick which ones to install and can delete them at any time.
Can Offlex analyse images?
Yes, with vision-capable models. Images you select are processed entirely on your device and are never uploaded.
How do I delete my data?
You can delete individual chats and downloaded models inside the app. Uninstalling Offlex removes all chat history, settings and models from your phone.
