Capture
Save URLs, videos, notes, and browser pages with source context intact.
AI bookmark manager for research recall
Find saved research by meaning, not memory.
Save links, videos, and notes into an AI knowledge base that summarizes sources, connects related ideas, and brings back the right reference when you ask naturally.
- Capture links, videos, and notes
- Summaries stay attached to sources
- Search by idea, not exact title
Semantic recall loop
Ask by meaning. Scan saved sources. Return to the evidence.
Saved sources

Returned source
SaaS pricing teardown video

Onboarding notes
Activation interview notes
Team-limit friction and setup hesitation.
Conversion research

Pricing page patterns and objection handling.
Source-backed answer
“Segment users by budget anxiety before showing upgrade prompts.”

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.

Returned by natural-language search
Capture a source before the reason disappears.
Let AI attach summary, topics, and source context.
Ask by idea later and return to the exact reference.
Product walkthrough
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.
Source-backed by design
Second Mind returns the saved source, summary, and workspace context together.
Private workspace
Saved research stays in your account and is not exposed as public discovery content.
Browser-native capture
Capture pages from the place research starts, then reuse them inside the web app.

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.
