# Quillen

> Quillen learns your voice from a single SOUL.md, finds the right conversations on X and LinkedIn, and drafts replies that wait for your approval by default.

Last updated: 29 July 2026.

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 wait for your approval by default. Autopilot can post a draft without that approval once it passes the voice lint, but it is off unless you turn it on for a campaign, and it is available only on the Team plan. Most social tools are publishing pipes: you write, they post on a schedule. Quillen works the other way round: discovery and qualification are the product, not an add on to a scheduler.

Who it is for: technical founders, solo operators, and small go to market teams who want inbound leads and an audience from X and LinkedIn, and who do not want to sound like a bot or risk their account.

**What it does.**

- Audience discovery: keyword and creator scraping across X and LinkedIn, plus watchlists of accounts worth tracking, scored against your ideal customer profile.
- Buyer intent qualification: an AI ranker scores every candidate post so you answer the people showing intent, not everyone who used the keyword.
- Voice: a SOUL.md persona learns your phrasing, rhythm, and antivocabulary from your own writing, and a lint pass blocks drafts that do not sound like you.
- Guardrails: human approval by default, conservative daily caps, randomized pacing between actions, a warmup gate on cold accounts, deduplication, and engagement cooldowns.
- Publishing: scheduled posts, threads, and a composer for planning a week at a time.
- Analytics: impressions, engagement, follower growth, and profile clicks per post and per account.

**What makes it different.**

- Outbound first. Discovery and qualification are the product, not an add on to a scheduler.
- Your voice, enforced. The persona engine is trained on your writing and every draft is linted against it.
- Human in the loop by default. Nothing posts without approval unless you explicitly turn on autopilot for a LinkedIn campaign, and even then only a draft that passes lint is eligible.
- Server side. No browser extension acting inside your logged in session, and no browser left open.

**Pricing.** Free to start, no card. Paid tiers:

- Starter: $49 per month or $470 per year. 1 connected account, 1 seat, about 20 replies a day, 1,000 AI credits a month.
- Pro: $99 per month or $950 per year. 2 connected accounts, 1 seat, about 50 replies a day, 3,000 AI credits a month.
- Team: $299 per month or $2,870 per year. 10 connected accounts, up to 5 seats, about 250 replies a day, 5,000 AI credits a month.

Yearly billing saves 20%. There is a free tier for evaluation with 100 AI credits a month, but discovery and LinkedIn are paid capabilities.

## Skills

- [Social listening](https://www.quillen.xyz/skills/social-listening): Social listening is the practice of monitoring public conversations for the specific words, people, and questions that matter to your business, so you can act on them while they are still live.
- [Keyword tracking](https://www.quillen.xyz/skills/keyword-tracking): Keyword tracking is running standing searches for specific phrases so that new posts containing them reach you continuously, rather than being found by scrolling.
- [Audience research](https://www.quillen.xyz/skills/audience-research): Audience research on social is reading what your buyers already write in public, in their own words, to learn the problems, vocabulary, and objections you should be addressing.
- [Competitor monitoring](https://www.quillen.xyz/skills/competitor-monitoring): Competitor monitoring on social is tracking what a rival ships, says, and gets told in public, in order to learn what their customers want and where they are underserved.
- [Ideal customer profile](https://www.quillen.xyz/skills/ideal-customer-profile): An ideal customer profile is a short, checkable description of the accounts you are best placed to win, written specifically so that most prospects fail it.
- [Lead scoring](https://www.quillen.xyz/skills/lead-scoring): Lead scoring is assigning a number to a prospect that predicts how likely they are to buy, so a limited amount of human attention goes to the people most likely to reward it.
- [Brand voice](https://www.quillen.xyz/skills/brand-voice): A brand voice is a documented set of concrete writing rules, examples, and forbidden words that let different people produce text that reads as one consistent author.
- [Reply writing](https://www.quillen.xyz/skills/reply-writing): Reply writing is the practice of contributing to somebody else conversation in a way that is useful to the readers of that thread, not only to the person who posted it.
- [Thread writing](https://www.quillen.xyz/skills/thread-writing): Thread writing is presenting a single argument across a sequence of connected posts, where each post is readable alone and the sequence is worth following.
- [DM outreach](https://www.quillen.xyz/skills/dm-outreach): DM outreach is contacting a prospect privately on a social platform, which works when the recipient already has a reason to recognise you and fails almost completely when they do not.
- [Content calendar](https://www.quillen.xyz/skills/content-calendar): A content calendar is a plan of what will be published, on which account, and when, kept far enough ahead to remove the daily blank page and no further.
- [Approval workflows](https://www.quillen.xyz/skills/approval-workflows): A social approval workflow is an agreed set of rules about which posts and replies need a second pair of eyes before publishing, and who provides them.
- [Account warm up](https://www.quillen.xyz/skills/account-warm-up): Account warm up is the practice of building normal activity history on a new or dormant social account before using it for outreach, so that its first outbound actions do not look like the first actions of a bot.
- [Engagement tracking](https://www.quillen.xyz/skills/engagement-tracking): Engagement tracking is keeping a durable record of every person you have interacted with on social, so that follow ups are deliberate and nobody is contacted repeatedly by accident.
- [Social media analytics](https://www.quillen.xyz/skills/social-media-analytics): Social media analytics is the practice of reading a small number of metrics that can change a decision, rather than reporting every number a platform exposes.
- [Personal branding](https://www.quillen.xyz/skills/personal-branding): Personal branding is deliberately becoming known for a specific thing among a specific group of people, so that opportunities arrive without being chased.

## Free tools

- [AI reply checker](https://www.quillen.xyz/tools/ai-reply-checker): Runs the same voice linter Quillen puts every generated draft through, against your text, in your browser. It flags the phrases that read as AI-written and tells you what to do instead.
- [Thread splitter](https://www.quillen.xyz/tools/thread-splitter): Splits a long piece of writing into posts that each fit the character limit, breaking at paragraph and sentence boundaries first and reserving room for the numbering.
