You're leaving reach on the table

You spend 4 hours reformatting

Copy-pasting your newsletter into LinkedIn, then rewriting it for Twitter, then figuring out Instagram - every single week. That's 200+ hours a year on pure formatting.

Your content sounds like ChatGPT

Generic AI tools strip your personality. The nuance, the dry humor, the specific way you phrase things - it's gone. Readers can tell immediately it's not really you.

You're only reaching subscribers

The people who already subscribed see your newsletter. But LinkedIn, Twitter, and Instagram audiences never discover you - because you never had the time to show up there.

Three steps. Done.

01

Paste your newsletter URL

Drop in any Substack or Beehiiv link. We fetch the full article, headlines, bylines, and your writing style - automatically.

02

AI generates 6 content pieces in your voice

Our model reads your newsletter and drafts a LinkedIn post, Twitter thread, 3 tweets, an Instagram carousel outline, an email teaser, and a Reels hook - all sounding like you.

03

Review, schedule, publish everywhere

Tweak what you like. Schedule posts with one click. No copy-pasting. No reformatting. Your content goes live on every platform while you focus on the next issue.

6 content pieces from one newsletter

Every output is drafted in your voice, ready to post.

LinkedIn
Long-Form Post

A 800-1200 word thought-leadership post with structured paragraphs, personal anecdotes pulled from your newsletter, and a strong CTA to subscribe.

X / Twitter
Full Thread

A 10-15 tweet numbered thread that distills your newsletter's key argument, data points, and takeaways into snappy, eminently retweetable format.

X / Twitter
3 Standalone Tweets

Three punchy, individual tweets - one insight, one contrarian take, one quotable line - each designed to drive engagement on its own.

Instagram
Carousel Outline

A 6-8 slide carousel script: cover slide, main points as slides, and a closing CTA slide - ready to drop into your design tool of choice.

Email
Teaser for Non-Subscribers

A 200-word re-engagement email that teases your best insights and funnels non-subscribers to your Substack or Beehiiv page.

Reels / TikTok
Short-Form Hook Script

A 30-60 second spoken script with a scroll-stopping opening hook, three key points, and a subscribe CTA - ready to record straight to camera.

Built for writers like you

You're a solopreneur, a consultant, or a coach. You spend hours pouring your expertise into a weekly newsletter that your subscribers genuinely love. But once it's sent, it's gone.

You know you should be reaching the massive audiences on LinkedIn and X. But the thought of sitting there reformatting, rewriting, and manually scheduling 6 different posts makes you hit “close tab” every single time.

We built Postliq for the writer who doesn't have 4 hours to spare, but refuses to let their best ideas stay trapped in an inbox. It's time to show up everywhere, without the burnout.

Frequently asked questions

Which newsletter platforms does it work with?

Any platform - Substack, Beehiiv, Ghost, ConvertKit, or just paste your text directly. No integrations needed.

Will it actually sound like me?

Yes - our voice training model learns from your existing writing. Paste 5-10 of your posts and it adapts to your tone, vocabulary and style.

Which social platforms does it post to?

LinkedIn, X/Twitter, and Instagram. More platforms coming soon.

How is this different from just using ChatGPT?

ChatGPT doesn't know your voice, can't schedule posts, and requires you to manually copy-paste everything. Postliq does the whole workflow in one place.

Is my newsletter content safe?

Yes. We never store your newsletter content after processing. Your data is never used to train AI models.

Can I cancel anytime?

Yes. No contracts, no commitments. Cancel from your dashboard anytime.

A quick note from the founder
Why I built Postliq

Hey there. I built Postliq because I was exhausted. I was spending hours writing a weekly newsletter and desperately wanted to grow on LinkedIn and X, but sitting there reformatting text on a Sunday afternoon was soul‑crushing.

I tried dumping my essays into ChatGPT, but the outputs sounded like robotic, generic garbage. I tried hiring a cheap freelancer, but they completely lost my tone of voice.

So I stopped compromising and built the exact tool I wished existed. Postliq completely removes the friction of showing up where your audience is. No complex prompts, no rewriting - just your real voice, everywhere.
