LeafLock is the AI that belongs to you. Chat, speak, generate images, and understand photos and documents with a complete AI companion that runs entirely on your iPhone. Not in the cloud. We don’t have servers. LeafLock is built on four promises: All AI processing happens on your device. Every response is generated using your iPhone’s own chip. Your prompts, conversations, photos, and documents are never sent to LeafLock servers or remote AI data centers. Your data never trains other AIs. Nothing you type, say, upload, or create is collected, harvested, or used to train anyone’s models. Your conversations are not a product, and they are not data we can access. Your chats stay on your iPhone. There is no account, no cloud storage, and no remote copy of your conversations. No sign-in, no tracking, and nothing stored on our servers. Delete a chat, and it is gone. Unlimited usage, free forever. No subscription, no credits, no daily limits, and no locked Pro tier. Your iPhone does the work, so you can use every feature as much as you want. What you can do with LeafLock: • Chat with a private AI assistant • Have natural voice conversations • Generate images directly on your iPhone • Read documents and extract text from photos • Ask questions about images and uploaded content • Ground answers with optional private web search • Track estimated energy, water, and carbon savings Cloud AI depends on remote data centers that consume electricity and water. LeafLock performs AI processing locally, giving you a more private and independent way to use AI. Your ideas. Your voice. Your creativity.

Restarting it, it stayed stuck on a black screen. After that, all further attempts to open the app immediately self-terminated. App has a feature to show how much energy you save using it, which is cool. UI otherwise seemed fine. Unfortunately I could not get it to work at all. I was looking forward to trying it out. I hope the developer can fix this issue. Using iPhone XS. ## Frequently asked questions about LeafLock ### Does LeafLock have ads? No, LeafLock does not contain advertisements.
