Bookmark manager vs source library
A bookmark manager and a source library look similar at first.
Both save things from the web.
But they are solving different problems.
A bookmark manager stores links
Bookmark managers are useful when the link is the thing you need.
Examples:
- a tool homepage
- a pricing page
- a design reference
- a dashboard
- a documentation index
- a list of resources
The job is organization.
Can you find the link again?
A source library stores usable material
A source library is for content you expect to read, quote, search, summarize, export, or reuse.
Examples:
- articles
- PDFs
- newsletters
- technical tutorials
- research reports
- YouTube transcripts
- saved highlights
The job is output.
Can you use the material again?
Why the distinction matters
If you treat every source like a bookmark, you lose the inside of the source.
You save a URL, but not the useful passage. You remember the article existed, but not the argument. You know you read something, but cannot find it when writing.
That is how a clean bookmark system can still fail.
A simple rule
Use a bookmark manager when you need the link.
Use a source library when you need the content inside the link.
Sigilla is built for the second case.
That is why it focuses on reading, highlighting, retrieval, Ask AI, source packs, and Markdown export.
