Is Quillen a good Commenter.ai alternative?

Yes. It targets the same goal, better comments to grow your audience, but instead of suggesting a comment on a post you found, it finds the conversations, drafts the reply in your own voice, and posts it after you approve.

Does Quillen need a Chrome extension?

No. Quillen runs server side through a sanctioned provider, so there is no extension to install and nothing to post by hand.

Does Quillen write in a preset style or my own voice?

Your own voice. A SOUL.md persona is built from your writing and every draft is checked against it, rather than picking from a set of commenting styles.

Can Quillen find the posts to reply to?

Yes. Watchlists and topic search surface the threads worth answering, so you are not scrolling to find each one yourself.

Quillen vs Commenter.ai

Commenter.ai is a Chrome extension that generates suggested comments on the post you are already looking at, in one of a set of commenting styles, which you then edit and post yourself. Quillen runs the whole loop server side: it finds the conversations worth answering, drafts replies in your own voice, and posts them on safe pacing after you approve. Here is an honest, point-by-point comparison.
