No account. No chat logs. No traces. Talk to the world's best AI models while your identity stays on your phone. Try it - you won't even find a sign-up screen.
Ask AI anything - your phone keeps the secret.
EnigmaAI gives you the world's most powerful AI models - ChatGPT, Claude, Gemini, Grok, and DeepSeek - with none of the surveillance. No account. No email. No phone number. Open the app and start chatting. That's it.
WHY PRIVATE AI MATTERS
You ask AI about your health, your money, your contracts, your relationships. On most AI apps, those conversations are tied to your identity and may be used to train future models. EnigmaAI was built on a different principle: what you ask is nobody's business - not even ours.
YOUR MESSAGES, SCRUBBED BEFORE THEY LEAVE YOUR PHONE
• Email addresses, phone numbers, credit card numbers, US Social Security numbers, and IPv4 addresses are automatically removed from your messages before transmission
• Photos are stripped of EXIF metadata and GPS location
• Blind routing removes your IP address before requests ever reach the AI providers
ZERO-KNOWLEDGE BY DESIGN
• No sign-up, no account, no identity - ever
• Conversations encrypted with keys protected by the Secure Enclave and stored only on your device
• No cloud sync, no backups on our servers
• No conversation logs - message content is never recorded
• Our servers process requests in memory only - nothing is written to disk
• Check our App Store privacy label: Data Not Collected
ALL THE FRONTIER MODELS, ONE APP
• ChatGPT (OpenAI), Claude (Anthropic), Gemini (Google), Grok (xAI), and DeepSeek - switch anytime, mid-conversation
• Thinking-effort controls and visible model reasoning
• Private AI image generation with GPT Image and Grok Imagine, saved to an encrypted on-device vault
DISAPPEAR ON DEMAND
• Stealth Mode: close the app and the session is gone
• Disappearing Chats: auto-delete after 24 hours
• One-tap deletion wipes everything, instantly and permanently
ONE PRIVATE AI CLIENT, EVERYWHERE
iPhone, iPad, and Mac (Apple silicon)
Built for the paranoid and the practical. Download EnigmaAI and ask what you've never dared to type.
Pro subscription unlocks premium models and gives you much higher usage limits for all frontier models and image generation. A free tier with lower limits is also available. Neither requires an account.
It was fine until I reached a limit and I can’t speak and I have to pay.. please consider removing this and it’s very annoying. I might go back toGoogle or ChatGPT
Developer Response
Sorry it cut you off mid-conversation. Free messages refill every day. You can close the paywall and chat again tomorrow without paying. Pro is there if you want a much higher allowance and don’t want to wait. If something else stopped working, email support@enigmaai.app and we’ll look.
Excellent private alternative to ChatGPT
matiku88
This app is fantastic. I use it to discuss my personal finances because I don't feel comfortable sharing that kind of sensitive information with ChatGPT, especally knowing it links conversations to my account.The app performs really well, respones are fast and high quality. My only minor complaint is that I occasionally hit the web search limit and have to wait until the next day for it to reset. It would be great if that limit were a bit more generous.Overall, it's been an excellent experience. Highly recommended.
Longest limit ever
sedonbonbon
It was great and easy to navigate right away u til i hit my message limit! And it doesn’t let you message again for like 72 hours??? That’s a bit extreme id say atleast with grok its like overnight then by the time you wake up you can use it again. Anyways i was shoot with it enough that i ignored the fact that you cant even speak to it verbally or hear any audio feedback but the theee day quota made me delete the entire . for good. Not worth it to me overall opinion” keep searching because this basically leaves you disappointed and you delete it”
Developer Response
Sorry for locking you out for days. We took your feedback and changed the free quota to a daily reset. We’re a new app and still experimenting with the setup, so this kind of note really helps. Voice replies are coming very soon.
Proper AI chat with local chat storage
Nutcase111
So far works really well. I feel more comfortable having my chats only on my own device without any cloud sync. The selection of models is decent.
• Enigma finally scales properly on iPad and Mac - readable column, sidebar, and Enter to send
• Updated UI design across the app
• Edit a sent message and send it again
• Creating a folder opens it right away
• Collapse every group in the model picker
• Waiting for an image now shows stepping Enigma rotors
