AO3 Inline Comment Companion
Highlight what moves you. Comment as you read.

This extension helps you stay connected to the stories you love on AO3. When a line stands out, something funny, emotional, or beautifully written, you just highlight the text. A small 💬 icon will appear next to it. Click it to leave a quick comment or personal note.

Your highlights and comments are saved directly in your browser. When you come back to the same fic or chapter, your notes will still be there. You’ll also see subtle markers showing which lines you’ve already commented on, so you can easily revisit your thoughts.

When you're ready to share, the extension gathers all your notes into one clean comment. You can copy and paste it into the AO3 comment box to let the author know what resonated with you.

✅ What you can use it for:
React to specific lines while reading

Save personal notes and emotional reactions

Keep track of what you want to say before commenting

Format your thoughts into a clear, organized message

Revisit your notes anytime you return to the same fic

🚫 What you can’t use it for:
Comments are not visible to the author unless you paste them into AO3 yourself

You can’t see comments from other users, and they can’t see yours

It doesn’t sync across devices or browsers

It doesn’t connect to your AO3 account

🔒 How it works:
All highlights and comments are saved locally in your browser's storage. Nothing is uploaded or shared. Only you can see your notes. You don’t need to create an account, and there’s no sign-in required.
