Private AI Chat Offline: L3M

L3M (Local Large Language Models) runs open AI models on your iPhone or iPad, with no account and no cloud. Ask your own files and see the source page of every answer. START IN SECONDS • On devices with Apple Intelligence, Apple's on-device model answers at once, with nothing to download • Or download a model from Hugging Face: each download shows its size, resumes after a lost connection and is checked against its published fingerprint • Add your own GGUF model from Files or a Hugging Face link KNOW WHAT FITS BEFORE YOU DOWNLOAD • Every model says whether it runs well, runs with tight memory, needs a check on your phone or won't run, with the memory arithmetic behind it • Answer settings for each model: style, length, temperature and more • Ask one question to several models and compare the answers side by side ASK YOUR OWN FILES • Add PDF, Word, PowerPoint and Excel files, notebooks, web pages, text and photos of text, many at once from Files or your cloud drive • File documents and chats into sections you name • Answers show citation chips with the page and passage they came from • Search across files and chats by words or by meaning TOOLS THAT RUN ON THE PHONE • Calculator, date and time and search my files, used by the model when it needs them and shown in the answer • Agents that work through several steps, and teams of models that review each other's answers • Attach a photo and ask about it YOURS TO KEEP • Export a whole chat or one answer as Markdown or PDF • Dictate a question with the microphone • Read answers aloud with Apple's voices, or download a neural voice • Delete everything, or open your chats and files, whenever you want • Works in Airplane Mode once a model is on your phone PRIVATE BY DESIGN There is no account. The app goes online only to download the models you choose, to check your purchase through Apple and RevenueCat, to send anonymous usage events, and to send feedback through iCloud when you choose to. Your chats, files, prompts and answers never leave your phone and are never part of the usage events. ONE PRICE Try everything free for 14 days. When the trial ends, L3M asks for a one-time unlock: no subscription, nothing renews. Restore Purchases is always on the paywall. GOOD TO KNOW Small models on a phone can be wrong, so check anything important. Downloaded models carry their own licences, shown on each model's page.
