Keep the source close
References help you revisit the context and decide how an idea applies to your work.

Silent animation: save an X post, keep its ideas in your library, and connect your own AI agent to use them. A text description follows.
Read the video description
A sample X post says: “Talk to 5 users before you launch. Find the problem they all share. Build the smallest useful solution.” Its link is pasted into Save2Brain.
Save2Brain extracts three useful ideas and stores them in your library, with the original source attached: talk to 5 users, find one shared problem, and build the smallest solution.
You connect your own AI agent and choose what it can read. When you ask “Help me launch my app,” it uses those saved ideas to suggest a launch plan and points back to the source.
Illustrative example with shortened timing. Your agent only reads what you allow.
From “save this” to “use this.”

Understand your InboxSTEP 03
Make your library your own
Edit an idea in your own words. Browse by Topic, gather ideas into Collections, and search whenever you need them. Open the source references to check the details.
Organize your librarySTEP 04
Put your knowledge to work
Connect a compatible AI tool on your computer so it can find relevant ideas from your library. You choose what it can read and when access ends. It can use those ideas while leaving your library in your hands.
How to connect your AI
Your ideas. Your context. Your choice.
Keep it useful
Refine a learning as your understanding grows, or remove it when you no longer need it.
Keep control
Your library is private. You choose which learnings a connected AI can read, and can stop future access at any time.
Start with one thing worth remembering.
A useful post, a thoughtful note, a lesson you want to use again.
