Comments for OneNote

Simply add comments in OneNote—just like in Word.

Built for 64-bit OneNote on Windows.

Select text, add a comment in an embedded side pane, and keep it attached when the original text moves within the page.

Comments for OneNote is a community fork of Steven M. Cohn's OneMore. It keeps the full OneMore feature set while adding a simple, Word-inspired commenting workflow.

This is an independent community project. It is not an official Microsoft or OneMore release.

Important: This add-on is not standalone. Install the official OneMore 7.2.0 x64 first, then install Comments for OneNote.

Features

• Add a comment from the OneMore ribbon or text context menu.
• View comments in a pane embedded inside the OneNote window.
• Store comments in hidden page metadata so they travel and sync with the page.
• Anchor comments to the exact selected occurrence, even when the same text appears more than once.
• Reconnect a comment after its source text moves to another paragraph on the same page.
• Jump to, edit, resolve, reopen, and delete comments.
• Remove the comment highlight when its comment is deleted while preserving other text formatting.
• Avoid unsafe guesses when identical text occurs in ambiguous locations.

Requirements

• Windows desktop OneNote from Microsoft Office.
• OneMore 7.2.0 installed first.
• 64-bit OneNote and OneMore. The 32-bit edition is not currently supported.

One-click install

1. Install the official OneMore 7.2.0 if needed.
2. Download Comments-for-OneNote-win-x64-v*.zip from this repository's Releases page.
3. Extract the complete ZIP and close OneNote.
4. Double-click Install.cmd.

OneNote will reopen automatically when installation finishes. Keep all extracted files together while installing.

If Windows prevents the double-click installer from running, open PowerShell in the extracted folder and use:

powershell.exe -NoProfile -ExecutionPolicy Bypass -File .\install.ps1

The installer uses a per-user COM registration override. It does not overwrite the official OneMore installation in Program Files.

To remove this community build and return to official OneMore, double-click Uninstall.cmd. The equivalent manual command is:

powershell.exe -NoProfile -ExecutionPolicy Bypass -File .\uninstall.ps1

Use

1. Select text within one paragraph.
2. Choose OneMore → Add Comment or right-click and choose Add Comment.
3. Enter the comment and save it.
4. Use OneMore → Comments Pane to show or hide the embedded pane.

Cross-paragraph selections are not yet supported.

How anchoring works

Each comment records the exact text offset, quote, OneNote object ID, and surrounding prefix/suffix context. The pane periodically checks the active page. If the object ID changes after a move, it scores candidate matches using the surrounding context before reconnecting. If matches remain ambiguous, it marks the comment unattached instead of linking to the wrong text.

Build from source

The project targets .NET Framework 4.8 and follows the upstream OneMore build layout. For 64-bit OneNote:

msbuild OneMore\OneMore.csproj /t:Build /p:Configuration=Debug /p:Platform=x64

Implementation: CommentFeature.cs. Tests: CommentStoreTests.cs.
