No account. No sign-in. Just ask. MarzsAI is a chat assistant for iPhone. There is nothing to create and nothing to log into. Open it and type. WHAT IT DOES Ask a question and it answers, a word at a time as the reply is written. Your conversations are stored only on this phone, and you can search back through every one of them. Ask for somewhere nearby and it searches without leaving the chat. Coffee, a hardware store, somewhere to eat. You get what it found with the distance to each one, and you can call the place or get directions from the same card. Say no to location and you type a town or a ZIP code instead. The search works the same either way. It remembers what is worth remembering between conversations. What you do, who is in your family, the thing you are allergic to. You can read the whole list in Settings, change any line of it, and delete any of it whenever you want. It is kept on this phone and in your own iCloud if you have iCloud turned on. It keeps a few other things for you. Vehicles, with what each one cost and what you have spent on it since. Trips, which can pull in the photos you already took over the days you pick and show where and when each was taken. Reminders, which arrive as notifications. When the assistant spots a vehicle, a trip or a reminder in what you said, it offers to add it, and nothing is added until you tap it. Two models to answer with. Considered takes longer and reasons further. Quick answers sooner and is better for short questions. You choose in Settings and you can change it whenever. Scan a page with the camera, or attach a PDF or a text file, and ask about it. Before a document's words are sent, you see exactly what will go, and a scan's picture never leaves this phone. Your files live in Digital Files, where pictures, PDFs and text open right inside the app. WHAT LEAVES THIS PHONE To write a reply, the app sends your message text to OpenRouter, which passes it to a model provider. Anything you save to memory is sent with it. Those are your words, handled by a company that is not us, and there is no version of this app that answers without it. Seven things leave this phone: your messages, the photos you attach to them, the area around you when you ask for somewhere nearby, which subscription you pick if you buy one, the record of that subscription, a number that stands for this copy of the app so your messages can be counted, and the internet address your phone connects from. Nothing else does. No advertising, no tracking, and nothing about what you tap. Asking for somewhere nearby goes to Apple's map service to run the search, and never to the model provider. Buying a subscription goes through the App Store, so your name, your address and your card never reach us. All of this is written out on first launch, before you agree to anything, and in full in the privacy policy. WHAT IT COSTS 25 messages a month, free. 500 a month with a subscription, and the first month is free if you have not had a trial before. Everything else in the app stays free.

Save any post from any app, and keep it after the original is gone. Kept saves a private snapshot, the text and the picture, of whatever you share to it. That restaurant from Threads, that workout from Instagram, that article for later: still there in six months, even if the author deletes it. • Works with Threads, X, Instagram, YouTube, TikTok, Reddit, Facebook, Telegram, WhatsApp, RED and Safari • Sorts itself into 16 topics, on your phone • Your notes, your collections, and search that finds what you only half remember • No account, no server, no tracking • Free for your first 30 saves HOW IT WORKS Tap Share in any app and choose Kept. That's it. Kept saves a snapshot — the text and the picture — onto your phone. Not a link that rots. When the author deletes the post six months later, or makes their account private, your copy is still there. IT SORTS ITSELF Everything lands in one timeline, newest first, the way you already read. Kept also reads what you saved and files it under sixteen topics — food, travel, fitness, tech, money, design, home, pets and more. That happens on your phone, by looking at the words. Nothing is uploaded to do it, and you can change any topic by hand. Add your own note to anything. Why you kept it, what it reminded you of. Your notes are searchable with everything else, and they sit with the thing they belong to. Group related things into collections. Places to eat. Ideas for the flat. Things to buy. COMPLETELY PRIVATE There is no account. There is no server. There are no analytics and no crash reports. Nothing you do in Kept is sent anywhere, because there is nowhere to send it. The only time Kept touches the network is when it fetches a snapshot, and then your phone asks that website for the link directly — exactly as if you had opened it yourself. Nobody sits in between. That also means nothing to sign up for, nothing to cancel, and nothing to leak. FREE, OR KEPT PRO The first 30 things you save are free, with snapshots, topics, notes, collections, search and export. Kept Pro adds iCloud sync between your iPhone and iPad, an iCloud backup in case you lose your phone, unlimited saving, and the web version at keptsave.com. Pay once for good, or subscribe yearly. Either way it's the same Pro. If you decide not to pay, nothing is taken away. Everything you already saved stays readable, searchable and exportable, forever. THIRTEEN LANGUAGES English, Spanish, French, German, Italian, Portuguese, Japanese, Korean, Vietnamese, Thai, Indonesian, Traditional Chinese and Simplified Chinese. Kept follows your phone unless you pick a different one. ABOUT VIDEO A video file you share straight to Kept is stored whole on your phone. A video behind a link is only downloaded where that platform's terms allow it — public Telegram channels and ordinary web pages. YouTube, TikTok, Instagram, Threads, Facebook, X, RED and Reddit do not allow offline copies, so for those Kept keeps the title, the thumbnail and the link. WHEN A SNAPSHOT FAILS Some pages need a login. When Kept cannot reach the original, it keeps the link and the text you shared anyway, marks the item, and you can try again later. Nothing is ever lost because a fetch failed. YOUR COPY, YOUR FILES Export everything to a zip whenever you like — items, notes, tags, collections and every picture and video, in one file you keep yourself. Import reads it back and only fills in what is missing, so an old backup never undoes today's work.
