Every AI session starts from scratch. Not anymore. Most people using AI tools today are rebuilding their context every time — switching between tools, starting new sessions, jumping between projects. Whatever the AI learned about how you work, what you've decided, what patterns you've developed — it's gone. Every time. Fathym fixes that. We're building the shared context layer that lives beneath your AI tools — capturing what you know, persisting how you work, and making that intelligence available everywhere you use AI. Session after session. Tool after tool. The AI stops asking questions it already knows the answers to. - Your decisions, patterns, and project context are stored in a portable vault — plain files, git-backed, owned by you - Every AI tool you use draws from the same shared context, so switching tools doesn't mean starting over - The longer you use it, the smarter it gets — session 50 knows your patterns, session 1 started from scratch - Works with the AI tools you already use: Claude, Cursor, Codex, Windsurf, and more Git democratized code ownership. Fathym democratizes AI context ownership. Your vault is open source, portable, and private by design. Fire us anytime — your context keeps running.
