Is Quillen an EngageAI alternative?

Yes, for people who want more than comment suggestions. EngageAI offers AI comment options in your browser that you post yourself. Quillen finds the right conversations, drafts replies in your own voice, and posts them on safe pacing after you approve.

Does Quillen suggest comments while I browse LinkedIn like EngageAI?

No. Quillen is not a browser extension on your feed. It works server side: it surfaces the right posts and drafts replies in your voice in a review queue, rather than suggesting comments as you scroll.

Does Quillen learn my voice or use preset tones?

Quillen learns your actual voice from a SOUL.md persona built on your own writing, instead of picking from a few generic tone presets.

Is Quillen safe for my LinkedIn account?

Quillen uses conservative rate limits, randomized gaps, deduplication, and a warmup gate that holds a newly connected account back from cold replies until it clears follower, connection, and account age thresholds. OAuth tokens are encrypted at rest, and by default every reply is reviewed by you before it posts.

Quillen vs EngageAI

EngageAI is a Chrome extension that reads the LinkedIn post you are viewing and suggests AI comments in a few preset tones, which you then post yourself. Quillen runs the whole loop server side: it finds the right conversations, drafts replies in your own voice, and posts them on safe pacing after you approve. Here is an honest comparison.
