Private. Yours. Forever.
OpenAI retains chats under its policies: "temporary" conversations are deleted within about 30 days. But there's a catch — legal holds like ongoing litigation can force OpenAI to retain your data far longer than you'd expect (many of which are going on RIGHT NOW). In practice, you can't guarantee that what you delete is truly gone.
Anthropic now retains chats for up to 5 years if you allow training. If you opt out, your data is still kept for about 30 days for operational reasons. Even deleted chats may linger during that window — the timeline is never fully under your control.
Google's Gemini keeps conversations for up to 72 hours when history is off, and other providers vary. And we all know how much Meta LOVES to collect data about you. The truth is, all these companies integrate your activity across ecosystems, and you have little visibility into how long it persists or how it's used.
Your data is not fully in your hands. Across today's AI platforms, your data is always someone else's asset. Data is their new currency, and you give up control while they keep the leverage.
With CoreLLM, it's different: your chats never leave your device. No hidden retention windows, no training without consent, no excuses. Your conversations remain yours.
At its core, CoreLLM is a Progressive Web App (PWA). You can still use it in the browser similar to ChatGPT, or you can install it on your device. However, unlike ChatGPT, you will be able to use it offline, and all your conversations will be stored on your device. Keep your existing workflows, but with true privacy.
Some more features:
CoreLLM will be free and open source. No need to explain why this is important.
All the basic functionality of ChatGPT, with some extra features like more model selection.
All chats stay on your device. Any referenced files are also stored on your device. They can be exported anytime.
Choose between DeepSeek, Qwen, Gemma, Meta Llama, and more. Switch models based on your specific needs and preferences.
Create profiles and knowledge banks with memories, which get updated as you chat with CoreLLM. Similar to ChatGPT memories, but you actually own your data.
CoreLLM is a Progressive Web App (PWA), so you can run it on your browser. You can also install it as an app on your device. Unlike Open WebUI, which requires Docker setup and technical configuration, CoreLLM is designed for ease of use and accessibility. You can use it offline, and all your data stays on your device without any complex configurations.
CoreLLM is for everyday users who value their privacy and want to keep their data secure. It's ideal for professionals, students, and privacy-conscious individuals who want to leverage AI without sacrificing control over their information.
CoreLLM keeps all your data on your device. Unlike ChatGPT, which sends your conversations to OpenAI's servers and retains them for weeks or months, CoreLLM processes everything locally. Your chats never leave your device, giving you complete control over your privacy.
CoreLLM will support multiple open-source models including DeepSeek, Qwen, Gemma, Meta Llama, and more. Note that for larger models, you'll need to download Ollama to use them. You'll be able to switch between models based on your needs, all running locally on your device. In the future, we plan to add support for API key-based models like OpenAI's GPT-5 and Anthropic's Claude, allowing you to choose between local and cloud-based processing.
Yes! Once you install CoreLLM as a PWA, it works completely offline. Your conversations, files, and AI processing all happen locally, so you don't need an internet connection to use it.
