Put what you hear, see, and think each day into one app. inFin is a local-first AI notes app. It captures your voice, text, images, and webpages, then turns scattered experiences into writing you can revisit and understand. Start with a thought. A passing idea on a walk, a sentence you didn’t finish in a meeting, or a conversation that mattered can be captured before it slips away. Open inFin to record audio, write a note, take a photo, or save something you found. There’s no need to carry another recording device. The iPhone, iPad, Mac, or Apple Watch you already use can become an entry point, with every capture synced on one timeline. inFin will keep adapting to the devices people use so longer recordings stay stable. If lighter hardware arrives later, it will simply become another way into inFin. Organizing and revisiting still happen in the same app. Work conversations, lectures, and ideas from the road come back together at the end of the day. After you record, inFin takes over the follow-up. Audio can be transcribed locally. Visual notes and webpage clippings join recordings on the same timeline, so you don’t need to move material between several apps or wait for time to organize it. When you want to come back, describe what you remember or search for a keyword. The phrase, the plan, or the article you read can return to view. The original audio sits beside the text, ready to replay. At the end of the day, return to the day. inFin organizes your conversations, notes, and saved material along the timeline, creates summaries and mind maps, and surfaces moments worth remembering. Feelings and choices you couldn’t understand at the time can gain another perspective on review. You can also ask: “Could I have handled that conversation better?” “What do I really care about in this relationship?” “Which recent moments deserve another thought?” inFin answers from your own records. It helps you review and reflect, notice details you missed, and pick up the next conversation with fuller context. The more it remembers, the more it understands you. The people you care about, the things you enjoy, plans you mention in passing, and writing you have read gradually form your memory. Your next question doesn’t have to start from zero. You can view, edit, or turn off the memories AI saves. Choose your AI. inFin Pro uses models such as DeepSeek and Kimi for summaries, mind maps, deep conversation, and reflection. Text and context are encrypted and sent directly to providers, never through inFin’s servers. AI features never upload recordings; inFin never retains or misuses your context. Your life doesn’t have to live on our cloud servers. Your private data belongs on your devices. Start for free. Recording, local transcription, visual notes, webpage clipping, search, playback, and iCloud sync are free and unlimited. inFin Pro adds in-depth AI summaries and reflections. Subscription prices (U.S. App Store): inFin Pro $5.99/month or $49.99/year; inFin Max $199.99/year (annual only). Prices vary by storefront and are shown at purchase. Subscriptions renew automatically through Apple ID and can be canceled in Settings. Live fully. Let inFin remember it, help you understand it, and grow with you. Requirements: iOS 16+ and paired watchOS 11+. Recording time varies by device and battery; keep devices charged and enable Do Not Disturb for important recordings. Back up important content and obtain consent before recording others.
