# Collect memories instead of bookmarks Every web browser has a sophisticated system to manage bookmarks. You can put them into folders and subfolders, and after that, you will probably never use them again. That's because directories structure is how computers work, but it isn't how your brain works. Our mind has a more efficient way of collecting information. When you need info back, think about it, and that's it - memory is back on the top of your hand. This app simulates biological function, allowing you to retrieve information instantly using words connected with seeking items. That saves your time and makes searching more intuitive. Brain3k does that with bookmarks (more data types to come) called memories. You put them into the app and then type any related words to find them. # Search with text instead of managing When adding new memory to Brain3k, the server analyzes the item's content and prepares a beautiful screenshot. Next time you want to find it, type a text related to it. Internal tags, description, title, summary, and URL are used to find it. The same as your brain works; just think about it. # Own tags and notes Sometimes automatic tags and page metadata aren't enough. What if you are collecting ideas for a specific project? In Brain3k, you can add your tags and notes. Of course, they are used when you are searching for memories. Why is this better than folders, you may ask? You can put a bookmark in one directory at a time, but you can add multiple tags to memory. # iOS, iPadOS and macOS sync Log in using Sign in with Apple or email and password on your iPhone, iPad, or MacBook. All your data are synchronized, and you will see new items on each platform without a single click. Of course, you will need only one subscription, no matter which version you are using. # Beautiful design and platform adaptation Each platform is different. Brain3k looks similar on iOS, iPadOS, and macOS, but it's tailored for each one individually. Additionally, it supports dark mode on each platform and portrait and landscape mode on iOS and iPadOS. # You are not a product No user tracking. No selling users' data. Brain3k is a paid application, so you are a client, not a product. We limited your personal data collection to a needed minimum, and we only use your email for account purposes. And that's it. Every data you upload stays private for you. All stability and crash tracking is made without linking this data to your device or account. # Unlimited test period and simple subscription When you create an account, your account capacity is limited to 100 memories. There is no time limit, and you can use your account as long as you want. If you need more memories, a Pro subscription is for you. $19.99 yearly will increase a memories limit to 5000 memories. # Legal Price may vary by location. Subscriptions will be charged to your credit card through your iTunes account. Your subscription will automatically renew unless canceled at least 24 hours before the end of the current period. You will not be able to cancel the subscription once activated. Manage your subscriptions in Account Settings after purchase.
