Diff Visualization

Super Document's Diff view lets you clearly see what the Agent has modified. Every addition, deletion, and replacement is marked with colors, as intuitive as code diffs.

What is Diff View

When the Agent modifies your document, Super Document doesn't directly replace the original text. Instead, it shows a comparison between before and after in Diff (difference) format. This allows you to:

• Precisely see what content was changed
• Understand the scope and impact of modifications
• Decide item by item whether to accept

Color Coding Meanings

Diff view uses four colors to distinguish different types of changes:

Change Type	Color	Marking Method	Meaning
Deletion	Red	Red background + red vertical line on left	This content was removed
Addition	Green	Green background + green vertical line on left	This is newly added content
Replacement	Red + Green combo	Red first then green, gradient transition	Original content replaced with new content
Movement	Blue	Blue background + arrow indicator	Content position has changed

Quick Reading Tips

• Red parts are "old", green parts are "new"
• If a section has both red and green, it's a replacement—red is original text, green is modified content
• Blue arrows indicate content was moved to another location

Three View Modes

Depending on the type of modification and your reading habits, Super Document provides three view modes:

Inline Mode

Deletions and additions are displayed on the same line. Suitable for small-range wording adjustments:

The implementation cycle for this plan is [-three months-]{+six months+},
requiring a team of [-5 people-]{+8 people+}.

Mobile defaults to this mode.

Side by Side Mode

Original text is shown on the left, modified content on the right. Suitable for large-scale rewrites, convenient for paragraph-by-paragraph comparison:

Original (Left)           |  Modified (Right)
--------------------------|---------------------------
Project started last year,|  Project started in Q3 2025,
progress is smooth.       |  80% of milestones completed.

PC defaults to this mode.

Unified Mode

Only displays the final result, with changed parts highlighted. Suitable for quickly browsing overall effect:

This mode is also used for pre-export preview.

You can switch view modes at any time in the toolbar at the top of the editor.

Navigating in Diff

When the Agent makes multiple changes, you can use shortcuts to quickly jump between changes:

Action	Shortcut	Description
Jump to next change	]	Cursor moves to next change
Jump to previous change	[	Cursor moves to previous change

Change Count

The top of the editor displays the total number of pending changes (e.g., "3/12 changes"), helping you track review progress.

Reason for Change

Each change comes with a reason explanation, telling you why the Agent made this modification. A qualified reason contains three elements:

Element	Meaning	Example
Purpose	Why the change was made	"Make expression more formal,符合商务文书规范"
Basis	What decision was based on	"Reference user preference: formal tone"
Scope	What was modified	"Only affects second paragraph, doesn't change overall structure"

You can click the reason icon next to the change to view the full explanation. If the reason is insufficient, this can be your basis for rejecting the change.
