Tips to Stay Safe With AI Assistants
Protecting your privacy while using AI assistants is as important as choosing the right model.
Always avoid sharing sensitive data such as personal identifiers, financial information, internal company documents, or confidential client details.
Use AI tools that offer transparent privacy policies, enable data‑control settings, and allow you to delete past interactions.
When possible, run models locally or in secure enterprise environments to minimize exposure. Smart AI usage means staying safe while doing it.
