You paid for an iPhone with Apple Intelligence built in. Notetaker AI is the app that finally puts it to work. Record any conversation, meeting, interview, lecture, or voice note. In seconds, get a full transcription, then let Apple Foundation Models — running entirely on your device — correct the text, identify speakers, generate a summary, extract key points, surface action items, and organize next steps. No internet. No subscription. No account. No data leaving your phone. This is not another recorder tied to a cloud plan. Notetaker AI is built natively for iOS 26 using Apple Speech for transcription, Apple Foundation Models for analysis, and Apple ActivityKit for Live Activities. You already own the hardware. Notetaker AI is the missing piece. RECORD ANYTHING Start with one tap. Pause and resume anytime. Audio is captured in high-quality AAC 48 kHz, the same codec used by Apple Voice Memos. A Live Activity on your Lock Screen and Dynamic Island shows elapsed time and audio levels in real time. You can also start, pause, and save recordings from your Apple Watch. INSTANT TRANSCRIPTION IN 15 LANGUAGES Powered by Apple SpeechAnalyzer, Notetaker AI supports French, English, Spanish, German, Italian, Portuguese, Dutch, Japanese, Chinese, Korean, Arabic, Russian, Turkish, and Polish. Long recordings are automatically split, processed, merged, and structured with speaker detection. AI ANALYSIS WITH APPLE FOUNDATION MODELS No ChatGPT. No API key. No cloud. Your iPhone generates: • corrected transcription with punctuation • speaker identification • smart summaries • key discussion points • action items and next steps • topic tags • auto-generated titles Everything runs on the Neural Engine, offline and on-device. CHAT WITH YOUR RECORDINGS Ask questions like: “What decisions were made?”, “List all action items,” or “What did Marie say about the budget?” The AI answers using the full transcription context, entirely on-device. DESIGNED FOR PRIVACY Zero data leaves your iPhone. No account. No sign-in. No tracking. Recordings stay stored locally in your Documents folder, protected with Face ID and passcode lock. No server. No cloud. No third party. SMART ORGANIZATION Notetaker AI automatically generates useful titles instead of “New Recording.” Favorite important recordings, filter by date or duration, and quickly find what matters. Calendar integration detects upcoming meetings, sends “Record now” reminders before calls, and a home screen widget gives you instant access to quick recording. APPLE WATCH + LIVE ACTIVITY Control recordings directly from your wrist and monitor them in real time. On iPhone, recording status stays visible on your Lock Screen and Dynamic Island with timer, waveform, and pause state always in view. WHY IT’S FREE Because Apple Intelligence already runs on your iPhone. Notetaker AI simply orchestrates the native frameworks Apple built into the device you already paid for. No servers to maintain. No AI API costs. Just your iPhone, unlocked to its full potential. Requires iOS 26 and Apple Intelligence enabled on device.

About

ChatOKF

Features
Read full description

A capable AI assistant that lives on your iPhone and iPad. The model runs on your device's own chip, so nothing you type is uploaded and nothing is logged. Once a model is downloaded, ChatOKF works in airplane mode. No account. No sign-in. No subscription. No ads, no analytics, no telemetry. WHAT YOU CAN DO - Ask anything: check the math on a loan, plan a week of dinners, untangle a confusing letter. - Show it a picture: a photo of a menu, a street sign or a whiteboard, straight from your library. Some models also listen to audio and watch video, frame by frame. - Hand it a document: a PDF, a Word file or a spreadsheet. It reads the tables inside and answers from the file, and one tap opens the page to check it. - Watch it think: the stronger models reason before they answer. Read the reasoning, tap Quick Answer to cut it short, or switch thinking off for speed. - Let it look things up: Wikipedia, today's headlines, the weather and web search are tools it can use, each behind its own switch. - Keep going: it suggests a sensible next question; swipe right to ask it. - Keep what it gives you: answers are typeset, tables and mathematics included. Search and rename your chats, share one as a PDF, and bring a deleted chat back within thirty days. - Talk instead of typing: tap the microphone and speak, and have replies read aloud in one of ten voices made on your device. MEMORY YOU CAN READ Tell it to remember something and it writes a short note, and the chat says what it wrote. Later questions are checked against your notes first, whichever model is answering. Every note is listed under Memories, to read or to delete. One switch, Total Recall, turns it all off. WHERE YOUR WORDS GO Nowhere, unless it looks something up. With Wikipedia on, your question is matched to an article on your device and only that article is downloaded. With web access on, the model's search terms go to a search engine and the pages it chooses are fetched. Settings, Privacy says exactly what leaves your device for each one. PICK YOUR MODEL Several open models are offered, and the list shows only what your device can hold, so every one you see will run. - Gemma 4 E2B and E4B: they see pictures, hear sound and watch video. - Qwen3.5 2B and 4B: good with tools and longer answers. - Ternary Bonsai 1.7B: small and fast, for devices with less memory. GOOD TO KNOW - The first launch downloads a model, from about half a gigabyte to a few gigabytes. Use Wi-Fi; after that, no network is needed. - Devices with more memory are offered stronger models, and newer chips answer faster. - Answers are generated and can be wrong. Check anything that matters. ChatOKF is written in Swift on Metal, and its source is on GitHub. Models are provided by their authors under their own licenses, including the Gemma Terms of Use.
