Second Brain

Second Brain とは？

Unlike most bookmarking tools, SecondBrain is completely free. It scrapes the actual content behind every link and converts it into vector embeddings, so you can search by meaning not just titles. Describe anything you vaguely remember and it finds it instantly. It also has a Sections feature to group your bookmarks however you like, create new ones inside a section, or move existing ones in. Free, semantic search, and real organization.
