PPQ

PPQ gives you every leading AI model in one app — and you only pay for what you actually use. No subscription. No monthly fee. Just add credits and ask. ONE APP, EVERY TOP MODEL Switch between the latest models from OpenAI, Anthropic, Google and more, all in a single conversation. Pick the right model for the job — a quick answer, deep reasoning, or creative writing — and never juggle multiple apps or subscriptions again. PAY PER QUERY, NOT PER MONTH Most AI apps lock the best models behind a $20/month subscription whether you use them once or a thousand times. PPQ is different: top up a balance and pay only for the queries you make. Light user? Spend a few cents. Power user? You're still in control of every credit. ASK WITH YOUR VOICE Tap the mic and just talk. PPQ transcribes your voice and answers instantly — perfect for asking on the go, hands-free. ASK ABOUT ANYTHING YOU SEE Snap a photo or attach one from your library and ask about it. Translate a menu, solve a problem on the whiteboard, identify an object, or get feedback on your work. CREATE IMAGES AND VIDEO Generate images and video right inside your conversation. Describe what you want and watch it come to life. PRIVATE, ENCRYPTED CHATS For sensitive questions, choose an encrypted model. Your messages are sealed to a secure enclave so the server can't read them — end-to-end privacy verified in hardware, on your device. YOUR HISTORY, SEARCHABLE Every conversation is saved and fully searchable — find any past chat by title or by what was actually said inside it. SIGN IN WITH A PASSKEY No passwords to remember. Sign in securely with Face ID or Touch ID using a passkey. WHY PPQ • All the top AI models in one place • Pay only for what you use — no subscription • Voice, photo, and text input • Image and video generation • Private, hardware-encrypted chats • Searchable conversation history • Secure passkey login Download PPQ and get pay-per-query access to the world's best AI — on your terms.
