Ask AI anything: your phone keeps the secret. EnigmaAI puts ChatGPT, Claude, Gemini, Grok, and DeepSeek in one private app. You don't need an account, an email, or a phone number. Open it and start typing. WHY PRIVATE AI MATTERS You ask AI about your health, your money, your contracts, your relationships. On most AI apps, every one of those questions is tied to an account in your name and may be used to train future models. On EnigmaAI, your chats stay on your device and aren't tied to an account. YOUR PERSONAL DETAILS NEVER LEAVE YOUR PHONE • Email addresses, phone numbers, credit card numbers, social security numbers, and IPv4 addresses are replaced with random stand-ins on your device before a message is sent • Photos are stripped of EXIF metadata and GPS location • Blind Routing removes your IP address before a request ever reaches an AI provider NO ACCOUNT NEEDED, NO LOGS, NO CLOUD • Use the free tier or Pro without an account • Chats are encrypted with keys protected by the Secure Enclave and stored only on your device • No cloud sync and no backups on our servers • No conversation logs: message content is never recorded • Our servers process requests in memory only, so message content is never written to disk • App Store privacy label: Data Not Collected THE TOP AI MODELS IN ONE APP • ChatGPT (OpenAI), Claude (Anthropic), Gemini (Google), Grok (xAI), and DeepSeek: switch anytime, even mid-conversation • Web search for up-to-date answers • Send a photo and ask about it • Set the thinking effort and see the model's reasoning • Private image generation with GPT Image and Grok Imagine, saved to an encrypted vault on your device LEAVE NO TRACE • Stealth Mode: the chat lives only in memory and disappears when you close the app • Disappearing Chats: gone 24 hours after the last message • App Lock with Face ID or Touch ID • One tap wipes everything, instantly and permanently BUILT FOR EVERYDAY USE • Folders with their own default instructions • Search your chats by what was said, not just by title • Edit a sent message and send it again • On-device voice dictation • iPhone, iPad, and Mac with Apple silicon FREE TO START Free messages refill every day. Pro unlocks premium models and much higher limits for every model, web search, and image generation. Neither needs an account. Pro renews automatically until you cancel in your Apple Account settings. Built for the paranoid and the practical. Download EnigmaAI and ask what you've never dared to type. EnigmaAI is an independent app and is not affiliated with OpenAI, Anthropic, Google, xAI, or DeepSeek. The AI provider you pick processes your prompts, with those personal details already replaced, to generate a reply.

EnigmaAI's advantage is ads (none vs shown) and ratings volume (10 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.
