# Quillen > Quillen learns your voice from a single SOUL.md, finds the right conversations across X and LinkedIn, and drafts replies you approve before anything posts. Quillen is an outbound social growth engine for X and LinkedIn. Most social tools are publishing pipes: you write, they post on a schedule. Quillen works the other way round. It finds the conversations already happening in your market, qualifies who is worth answering, and drafts the reply or DM in your own voice, which you approve before anything goes out. 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, deduplication, engagement cooldowns, and account health pausing. - 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, which is gated to the Team plan and still requires a draft to pass lint. - Server side. No browser extension acting inside your logged in session, and no browser left open. ## Pricing Free to start, no card.
