Privacy concerns are often the first thing people mention when discussing online AI tools, especially free ones. With this platform Overchat AI, the session model works in your favor because nothing is permanently tied to your identity. You can still have long, meaningful conversations, and the AI remembers context within your current session. For sensitive work or experimental prompts, you can simply close the tab when done, and no history follows you. This approach offers a different trade-off compared to logged-in services: you lose persistent memory across days, but you gain complete anonymity and zero data retention. I find that perfect for one-off research questions or trying risky prompts without consequences.
