Local Chat allows you to run the latest open language models on your Mac, iPad, and iPhone. Once you've downloaded the models, you can use the chat function even when your device is offline. Your chats remain totally private, since no internet connection is required to interact with the chatbots. It's like having your very own ChatGPT right on your device. You can choose to save your chat history on your devices or delete your chats automatically after you're finished. Any chats that you choose to save in your history will be synced via your private iCloud storage to your other devices. Try leading models from the open-source community, including Llama, Gemma, Qwen, Mistral, DeepSeek, and Kimi. Choose from different sizes to find the best fit for your device. You can also customize the chatbot's personality with a system prompt, whether you prefer a helpful assistant, an encouraging coach, a witty conversationalist, or anything else you can imagine. The chat function works with the following devices: - Mac (M1 and later) - iPhone 12 and later - iPad Pro (M1 and later) - iPad Air (4th generation and later) - iPad mini (6th generation and later) - iPad (10th generation and later) On earlier devices, you can view your chat history from your other devices synced via your private iCloud storage. Local Chat is just getting started, and we're planning to continue adding new features in the coming months. If you have any feedback about the app, we'd love to hear it at feedback@localchat.co. --- Privacy policy: https://localchat.co/privacy Terms of use: https://localchat.co/terms

Read full description

【QuickScan】turns the camera in your pocket into a document workspace: capture paper into clear digital files, then find, edit and send them without switching apps. Eight Scan Modes Documents, books, ID cards, business cards, QR codes, exam papers, tables and on-camera translation each come with their own framing guide, so every capture starts out square and readable. Scan and Translate Point the camera at text in another language and read it in yours. Choose the target language, pull an image in from your photo library, or switch on the torch when the light is poor. PDF Toolkit Split, merge, compress, reorder and password-protect PDFs, turn pages into images, and add annotations, watermarks or a handwritten signature before you send anything out. Format Conversion Move a document between Word, Excel, PDF and image formats, pull selectable text out of a scan, or translate an entire file in one pass. Files That Stay Organized Sort scans into categories and folders, search by name, rename or move what you need, and bring back anything deleted in the last seven days from the Recycle Bin. Scan it once, keep it organized, send it from anywhere — download 【QScan】 and see how much paperwork it clears off your desk.
