You save it for later. And later, it's gone. 4later is your personal AI assistant for everything you'll need later. It keeps it all in one place, puts it in order, and answers when you ask. Save. Forget. Ask. SAVE Articles, links, notes, PDFs, photos, videos, and voice memos. From the share sheet, with Siri, or by email. Files in your iCloud Drive and Dropbox folders are added on their own. All in one place. FORGET Create folders? Add tags? You don't have to. 4later understands what each item is about, summarizes it, and files it in the right topic. And when you need something again, 4later brings it back. Tonight. This weekend. Whenever you choose. In your calendar, too, if you like. ASK "Is my dishwasher still under warranty?" "When does my passport expire?" "What was that pasta recipe my friend sent me?" 4later reads your invoices, letters, and photos, and answers. Not with a file. With the answer. Other AIs know everything about the world. 4later knows what's in your documents. And if you want, so does your AI: connect 4later to Claude and more. SHARE Share topics with family, friends, or colleagues. The household paperwork. The vacation plans. The project ideas. You decide who can view, add, or edit. EVERYWHERE iPhone. iPad. Mac. Always in sync. With Siri, Shortcuts, and Spotlight. Just say "Ask 4later." PRIVATE Developed in Germany. Stored in the EU. The AI runs in the EU, too, and your content never trains AI models. No ads. No tracking. GDPR compliant. No templates. No databases. No learning curve. Staying organized is work. From now on, 4later does it. Start free. No subscription required. Basic and Premium add more storage, more AI questions, and email import.
