AI bookmark manager for research recall.
Save web pages, videos, and notes into Smart Spaces so every project keeps its sources, summaries, and next ideas together.
Saved source
SaaS pricing teardown
Video summary, transcript, and tags kept together.
Returned context
Saved clip, related notes, and customer interview found in one search.
From scattered source to answer you can trust.
Common tools help you store information. Second Mind keeps the source, meaning, and retrieval path together so useful context returns when work depends on it.
Common approach
Save first, reconstruct later.
Second Mind
Capture, connect, recall with source.
Traditional methods
Useful for capture, weak for return.
Advantages
- Fast to save
- Familiar tools
Disadvantages
- Context splits across tabs, notes, and folders
- Recall depends on exact keywords and memory
Second Mind approach
Capture becomes connected recall.
Advantages
- Source, summary, and meaning stay together
- Natural-language recall returns evidence
More
- Related sources surface without manual filing
- Search leads directly into the next useful action
Workflow replay
Watch context move from capture to recall
Common path
Bookmark it
The source is saved, but the reason you needed it disappears.
Second Mind
Capture source
Save the page, video, or note into a Smart Space with the original context attached.
Common path
Summarize later
Notes, screenshots, and transcripts drift into separate tools.
Second Mind
Understand automatically
Second Mind extracts the useful points and keeps them beside the source.
Common path
Tag by hand
Folders and manual tags age quickly when projects change.
Second Mind
Connect meaning
Related ideas are linked by topic, not by where you remembered to file them.
Common path
Search your memory
You remember the idea, but not the tab, folder, or exact keyword.
Second Mind
Recall with evidence
Ask in natural language and get the right source path back.
Returned source, saved summary, related interview, and next writing angle.
The problem
Capturing knowledge is easy. Using it later is where it breaks.
Bookmarks preserve the URL. Notes preserve fragments. Neither keeps the source, summary, meaning, and recall path together when work depends on it.
Sources split everywhere
Links, videos, notes, and project context end up in different tools with the reason you saved them missing.
Search needs exact memory
You remember the idea, but not the tab, folder, title, or keyword that gets you back to it.
Research becomes rework
Every writing, planning, or product decision starts with rebuilding context you already captured.
Why I built Second Mind
I kept saving useful research, then losing the thread when I needed it: the source in one place, the note in another, and the original reason gone.
The painful part was not collecting information. It was trusting that I could find the right source again before a decision, post, feature, or customer call.
So I built Second Mind to keep captured sources, AI summaries, semantic tags, and natural-language recall in one workspace.
What used to take another research session should take one search.
