Yes. You can download a model and run it on your own computer, cut off from the internet, so nothing you type leaves your machine. Most laptops cannot run the newest large models, so expect less reasoning power than the big online chatbots. LM Studio is a good starting point.

What computer do I need to run a Local AI Model?
Check your RAM, or your graphics card memory, first. The model has to sit comfortably under that amount, never right at the limit. A model that fits on your disk can still be too heavy to run. LM Studio downloads models for you, but it does not test whether your computer can handle them.
Why did Mistral remove Agents?
Because AI tools are moving from agents to modular building blocks. An agent is just instructions, knowledge and tools put together, and the chatbot already has all three. In Mistral you now combine a Skill, a library and a connector yourself, which is messier than picking one ready-made agent.
Why can I not find Gems in Gemini?
Because Gems have been deprecated and the feature is no longer available in Gemini. AI tools are moving away from separate custom bots towards skills, so the idea of saved instructions now lives under a different setup. There is no point looking for the Gems menu.
