Features
Everything you need to show up in your voice
Quillen finds the right conversations, drafts replies that sound like you, and keeps your accounts healthy. You stay in the loop the whole way.
Voice
Your real voice, not a tone toggle
A SOUL.md persona engine learns your phrasing, your antivocabulary, and your rhythm from your own writing. Replies read like you wrote them, because they are trained on you.
Targeting
Find the right people, ranked by fit
ICP search across LinkedIn and X surfaces real prospects and scores them against your audience. Build watchlists of the people and topics worth engaging.
Queue
One queue, every platform
X and LinkedIn in a single inbox. Quillen drafts replies and lines them up; you approve the ones that fit and it posts on safe pacing.
Control
Human in the loop by default
Every reply waits for your approval. No surprise posts, no offbrand takes. Turn on auto only where you trust it, never by default.
Safety
Safe, antiban pacing
Official platform APIs and third party providers, conservative rate limits, randomized gaps between actions, a warmup gate on cold accounts, and deduplication so nobody is contacted repeatedly.
Reporting
A daily report of what your voice did
Every morning, a clean digest of replies posted, conversations started, and new prospects found. No dashboard spelunking to know it is working.
Team
Run it together
On Team, invite teammates with roles, manage seats, and keep one shared workspace. Everyone shows up in their own voice under one roof.
Common questions
Does Quillen post without my approval?
No. Human in the loop is the default. Every reply Quillen drafts waits in your queue until you approve it. An opt in autopilot exists per LinkedIn campaign, off unless you switch it on yourself.
Will using Quillen get my account restricted?
Quillen posts through official platform APIs and third party providers rather than a browser extension driving your logged in session. On top of that it enforces conservative rate limits, randomized gaps between actions, deduplication and a cooldown so the same person is not replied to repeatedly, and a warmup gate that holds a newly connected account back from cold replies until it clears follower, connection, and account age thresholds.
How does Quillen learn my voice?
It builds a SOUL.md persona from your own writing: your phrasing, your rhythm, and an antivocabulary of words you would never use. It is a voice engine, not a tone dropdown, so two people using Quillen on the same thread do not come out sounding like the same intern. Every generated reply is checked against that persona before it reaches your queue.
Which platforms does Quillen support?
X and LinkedIn. Both feed a single approval queue, so you are not juggling tabs to keep up with each one.
Do I need a credit card to try it?
No. You can sign up free and start replying on X to see whether the voice actually sounds like you. LinkedIn, audience discovery, and higher volume are paid. Pay monthly or save 20% yearly, and cancel anytime.
Can my whole team use one account?
Yes. The Team plan supports multiple seats with roles in one shared workspace, and each person keeps their own persona, so everyone still shows up in their own voice.
