The privacy problem with all three
ChatGPT, Claude, and Gemini all have the same fundamental privacy issue: your conversations are tied to your account. Even if you disable training data use, your messages still pass through their servers, are visible to employees under certain policies, and are subject to legal requests.
GPTAnon routes to all three of these models while stripping that data linkage. You get the same model quality — GPT-4o's reasoning, Claude's document handling, Gemini's web search — without creating accounts on any of those platforms or having your conversations logged.
