Quick answer

What does Quillen actually do?

Quillen is an outbound social growth engine for X and LinkedIn. It finds the conversations already happening in your market, scores them for buyer intent, and drafts replies in your voice that you approve before anything posts.It turns “I should post more” into a daily habit you can keep, so you show up consistently without it eating your evenings or risking your account.

Learns your real voice

A SOUL.md persona from your own posts, phrasing, antivocabulary, rhythm. Not a tone toggle.

Finds the right rooms

Watchlists and topic search surface the people and threads worth replying to, ready in your queue.

You approve, it posts

Nothing goes out without you by default. Official platform APIs and third party providers, human paced, account safe by design.

Four ways Quillen gets you showing up

Everything you need to be present every day, in your voice, in one queue.

Head of Marketing

Quillen scores every prospect for relevance, so my team skips the noise and only works the ones worth it. We got our week back.

Co-Founder

Quillen drafts, schedules and runs social for Preferences AI. It's a marketing lead that never clocks out.

Co-Founder

I hate outreach. Quillen is the only reason it actually happens.

Vice President · JPMorgan Chase

I run socials for three side businesses on autopilot with Quillen, posting in my voice while I'm at the day job.

  • dry, not hyped
  • short lines

Sounds like you, not a bot

A persona engine learns your phrasing, slang and rhythm from your own posts, so replies land like something you'd actually type, not a chirpy AI “great point!”

how are you thinking about outbound in 2026?

Replies that fit the thread

Each draft reacts to the actual post and person in front of you, not a copy paste template.

Audience discovery

Surfaces the real people already engaging with you and your space, ready to reply to.

Quota emptied in one burst, then silent.

~15 replies a day, uneven gaps, spread across it.

  • Official APIs
  • Daily cap
  • Pauses at the first health warning

Engagement, not spam

Most autocommenters blast volume and quietly get accounts flagged. Quillen posts a handful of real replies a day, on server side platform access, with your approval by default and pacing that mimics you, presence that compounds without the ban risk.

One place

One queue. Every platform. Your voice.

Drafts, approvals, and posting for X and LinkedIn, in a single inbox that sounds like you, never a bot.

On X

“post every day” is survivorship bias tbh. i post like 3x a week and reply a ton, works way better for me

Approved · posted to X
On LinkedIn

we built the audience after the product for a year. do not recommend, everything is 10x harder in that order

Approved · posted to LinkedIn
Your queue

Draft ready. Approve it as is, tweak a word, or skip, nothing posts until you say so.

Waiting on you
Account safety

Won't this get my account flagged?

The honest answer: not the way we built it. No extension in your browser, no volume games, no full auto by default.

Server side, not a browser bot

X through the official X API, LinkedIn through a third party provider. No extension inside your own session.

Human paced activity

Conservative antiban pacing with randomized gaps and daily caps. Slow on purpose.

You stay in control

By default you approve every reply before it posts. Randomized pacing, and a warmup gate that holds new accounts back from cold replies until they clear follower, connection, and account age thresholds.

How it works

From cold profile to daily presence in 3 steps

Step one

Define your voice

Import your posts or paste samples. Quillen synthesizes a SOUL.md persona that captures how you actually write.

SOUL.md · voice fingerprint captured
Step two

Connect your accounts

Link X through the official API and LinkedIn through a third party provider. Build watchlists of the people and topics worth engaging.

Step three

Approve and post

Quillen drafts in your voice and queues them. Approve with a tap and it posts. By default nothing goes out without you.

FAQ

Questions, answered

What happens if a platform flags my account anyway?

Quillen paces conservatively by design: randomized gaps between actions, per account and per member daily caps, deduplication, engagement cooldowns, and a warmup gate that holds a newly connected account back from cold replies until it clears follower, connection, and account age thresholds. If a connection loses its authorization, it is flagged for reconnect rather than retried blindly, and nothing posts on it in the meantime.

Can people tell the replies are AI?

They read like you, because they are trained on you, not a generic tone setting. And you review every draft before it posts.

Is Quillen free to start?

Yes. Start free with no card and draft replies in your voice on X, with human approval on every one. Upgrade for LinkedIn, audience discovery and higher volume, or pay yearly and save 20%. Cancel anytime.

Which platforms are supported?

X and LinkedIn today, with more platforms on the way. Quillen hands off whatever a platform cannot automate as clean manual drafts.

What is a SOUL.md?

Your voice captured as a structured persona file: phrasing, antivocabulary, formatting, and intent. Quillen builds it from your posts or samples and reuses it on every reply.

Do I have to approve everything?

By default, yes. The one exception is an opt in autopilot you switch on yourself per LinkedIn campaign; Quillen never assumes it.
