Your second mind, ready before you forget.

Save links, videos, notes, and ideas. Second Mind organizes them, remembers the context, and helps you find answers by meaning — not just exact words.

  • Capture links, videos, and notes
  • Summaries stay attached to sources
  • Search by idea, not exact title

The retrieval gap

You captured the source. The hard part is using it later.

High-output people lose time digging through tabs, bookmarks, notes, and old chats for research they already captured. Second Mind keeps the source, summary, topics, and workspace context together so future search starts from meaning, not folder memory.

From saved source to useful answer.

The core loop is simple: capture once, let AI attach context, organize by project, then ask naturally when work depends on the source.

Built for research recall

I built Second Mind for the moment when you know you saved the right source, but cannot remember where it is, what it was called, or why it mattered.

The first version focuses on the core loop: save useful sources, understand them quickly, and retrieve the right reference when work depends on it.

What credits mean

Searching your saved resources does not spend credits. Credits are used when Second Mind processes a new source with AI, such as generating summaries, topics, or study notes. Free credits are granted once at signup; Master credits reset each billing period.

FAQ

Short answers before you start.

What can I use today?

You can start with URL/video/note capture, AI summaries, semantic search, Smart Spaces, and the Chrome extension.

Is Second Mind only for bookmarks?

No. Bookmarks are the entry point; source-backed recall is the outcome. Second Mind keeps summaries, topics, Smart Spaces, and retrieval context attached.

How is it different from Notion, Obsidian, Pocket, or Raindrop?

Those tools are strong at storage. Second Mind is built around retrieval: capture a source, enrich it with AI context, then search by meaning later.

Do searches spend credits?

No. Searching your saved resources does not spend credits. Credits are used when Second Mind processes a new source with AI, such as generating summaries, topics, or study notes.

Can I save from the browser?

Yes. The Chrome extension can save pages, keep sticky notes on URLs, and create Smart Spaces from browser tab groups.

Can I add PDF resources?

Direct PDF import is coming soon. Today, use web links, videos, notes, Smart Spaces, Study Notes, and semantic search.
