Transform your device into a personal AI assistant that works completely offline. DeepThink runs entirely on your device, giving you unlimited conversations with absolute privacy – no internet required and we never transmit your messages anywhere. One purchase, unlimited access. No subscriptions, no accounts, no API keys needed. Share with up to six family members through Family Sharing. While we may transition to a subscription model in the future, anyone who purchases now will have lifetime access to the app at no additional cost. DeepThink is powered by DeepSeek R-1, a groundbreaking AI model distilled and optimized for mobile devices. R-1 represents a new generation of AI assistant that carefully performs internal self-reflection and reasoning before responding. Until recently, even leading AI services would generate answers without proper reasoning steps. This led to errors on seemingly simple questions like "Is 9.11 greater than 9.9" and "How many letter R's are in the word Strawberry". DeepThink, through R-1's methodical reasoning process, tackles these examples and much more with accuracy. Key Features: • Complete privacy – all processing happens on your device • Works offline – think with AI anywhere, anytime • Unlimited conversations – no usage limits or extra fees • Output has formatted Markdown and LaTeX rendering • Full chat history with conversation review and resume • Copy responses as rich text or Markdown • Family Sharing enabled – share with up to 6 family members • Thoughtful responses through AI self-reflection • Simple temperature controls to fine-tune responses • Advanced settings for power users While DeepThink may not beat online enterprise AI services for many uses, it excels at being your offline and private thinking partner. The rare occasions where it needs a reset are easily handled with the stop button or by adjusting temperature settings. Coming Soon to free updates: • Additional AI models • Faster performance • Editable context Like all AI systems, DeepThink may occasionally make mistakes. Users should verify important information and are responsible for how they use the AI's output. We believe in being transparent about both capabilities and limitations while delivering genuine value through private, offline AI assistance. We're passionate about making DeepThink better with each update. Your feedback and suggestions play a crucial role in shaping future versions – we read every comment and feature request. Join us in evolving DeepThink into an even more capable offline AI companion. Share your thoughts with us @3DTOPO on X (formally Twitter), through App Store reviews or support contact information.
