BrainYak: why your memory should belong to you
Every major platform is building memory to keep you inside their walls. BrainYak was built to keep your thoughts to yourself. It is a personal knowledge vault that connects to every tool you use, stores your context in one place, and lets you decide what gets shared and with whom. No lock-in. No memory mining. Your vault, your rules. We built it because the alternative was handing our working memory to companies with structural incentives to mine it. brainyak.app
