Local Brain vs LocalQuill

Run Large Language Models locally on your device with full offline capability. You can choose from multiple available models and create multiple chat contexts using different models. The power of AI in your pocket without hurting your privacy.

LocalQuill is a private AI that lives on your phone. Chat with it, ask it anything, and let it fix your writing, without sending a single character to a server. Add the LocalQuill keyboard and get one-tap Fix, Rewrite and Translate in any app, in your own voice, powered by the on-device model in your phone. LocalQuill learns how you write, the words you actually use, and keeps that profile inside the keyboard where nothing can read it. The chat is a real assistant: explain, summarize, draft emails, plan, brainstorm, translate, read text out of photos, dictate by voice, and keep a memory of what matters to you. The model runs on the device: no account, no cloud, no tracking, and it works in airplane mode. - One-tap Fix that keeps your voice - Rewrite with a tone dial: casual, formal, shorter - Translate to 27 languages from the keyboard - Click-to-correct spelling chips, never silent autocorrect - No Full Access needed. The keyboard never touches the internet. - Chat with memory, photo text reading, dictation and read-aloud - Everything stored on your phone. Delete it any time. AI features use Apple Intelligence (iPhone 15 Pro or newer, iOS 26 or later). Spelling correction works on every supported iPhone.
