About

LocalKeep

LocalKeep is your AI text assistant that runs 100% on your device. Nothing ever leaves your iPhone, iPad, or Mac: zero servers, zero accounts, zero analytics. WHY LOCALKEEP IS DIFFERENT Most AI apps send your text to remote servers. LocalKeep uses the artificial intelligence built into your device (Apple Intelligence), so your documents, emails, and notes never leave your hardware. We couldn't receive them even if we wanted to: there is no server. • 100% on your device. Zero servers. • Summarize, extract, and rewrite without sending anything to the cloud. • Works offline, even in airplane mode. • Free. WHAT YOU CAN DO SUMMARIZE — Turn long texts into a one-sentence TL;DR, key bullet points, or a short paragraph. Multi-page texts are automatically processed in parts. EXTRACT — Pull what matters out of meeting notes, emails, and documents: key points, tasks with owner and deadline, and entities (people, dates, amounts, organizations). REWRITE — Change the tone (formal or casual), make it shorter or longer, fix spelling and grammar, or simplify the language. With a before-and-after view. BUILT INTO YOUR WORKFLOW • Share extension: select text in Safari, Notes, or Mail and summarize it instantly. • Streaming results: watch the text generate in real time. • Copy or share the result with one tap. • Multi-language: detects the language of your text and responds in kind, or pick the output language yourself. REAL PRIVACY, NOT FINE PRINT This app's privacy label says "Data Not Collected" because it is the technical truth: no network, no server, no account. You can verify it with any traffic monitor. REQUIREMENTS LocalKeep uses Apple Intelligence, available on iPhone 15 Pro or later, and iPad and Mac with M1 chip or later, with Apple Intelligence turned on.
