# Which ChatGPT alternative fits what you need?

Choose by task and data route. The directory compares hosted assistants, including [Duck.ai](https://ethicalstack.ai/products/duck-ai/), [Proton Lumo](https://ethicalstack.ai/products/proton-lumo/), [Brave Leo](https://ethicalstack.ai/products/brave-leo/), [Claude](https://ethicalstack.ai/products/claude/), and [Mistral Vibe (formerly Le Chat)](https://ethicalstack.ai/products/le-chat/), plus open models you can run yourself. If privacy is your main requirement, compare the exact product and hosting route before moving sensitive work. [See what local setup changes](https://ethicalstack.ai/guides/private-ai/#local-options) about where prompts are processed.

[Duck.ai](https://ethicalstack.ai/products/duck-ai/) and [Proton Lumo](https://ethicalstack.ai/products/proton-lumo/) have separate profiles for their hosted privacy routes: [Duck.ai privacy details ↗](https://duckduckgo.com/duckduckgo-help-pages/duckai/ai-chat-privacy) and [Lumo privacy details ↗](https://proton.me/support/lumo-privacy). Compare their retention and training protections alongside the underlying model and company findings.

Open the [chatbot alternatives with a documented local-model route](https://ethicalstack.ai/compare/chatbots/?require=local&exclude=products%2Fchatgpt) to find a setup you can run on your device. Requirements apply before the overall ranking. See [compare models](https://ethicalstack.ai/compare/models/) for model choices.

## How do I choose and switch?

Pick one ordinary task and try it with non-sensitive material. Check that the alternative supports your language, files, search, and any custom instructions you use. For local models, confirm the app is running a downloaded model rather than routing to a cloud endpoint. Export only the old chats you need, remove personal details before moving them, and check the current training and retention setting on every device.

For a task that needs no AI, use the source document, a trusted reference, or a person with the right expertise. Read [private AI chat controls](https://ethicalstack.ai/guides/private-ai/) and [training-data evidence](https://ethicalstack.ai/guides/ai-training-permission/) before deciding what to share.
