Concepts

This page explains the main user-facing ideas in InfoDigest.

Content item

A content item is the basic unit in your library.

It may start from:

• a web URL
• a WeChat article
• pasted text
• Markdown

Reading states

InfoDigest uses simple reading states so your library stays sortable:

• UNREAD
• READING
• READ

Use them as workflow markers, not as strict judgments about whether you understood everything.

Summary

A summary is the short version of a saved item.

Use it to:

• decide whether to read the full item now
• recall the main ideas later
• support review without reopening the original source every time

Feed

A feed item is a saved piece of information after InfoDigest has already done the first pass of extraction and distillation.

Use feeds when you want to:

• scan what is worth deeper attention
• reopen something for reading
• choose references before moving into active work

Workspace

The workspace is the active thinking layer of the product.

It is where you:

• start from an initial idea
• pull in references from your own saved library
• get an editable draft article
• continue writing in your own words

Highlight and note

Highlights mark the exact parts you want to keep.

Notes add your own interpretation on top of the source text.

Together, they turn passive reading into active understanding.

Tag

Tags are lightweight organization labels.

Use them for:

• projects
• themes
• people
• urgency
• source buckets

Review

Review is the memory layer of the product.

It helps you revisit important content over time instead of rereading everything from the beginning.

Knowledge graph

The knowledge graph is the relationship layer of the product.

It helps you see:

• similarity
• tension
• support
• shared entities
• topic clusters
