1 raw thought, 5 platform-native formats

Post like you, without writing like it’s your job.

Paste a rough thought, bullet list, or transcript. PrimusPost applies your voice profile and writes LinkedIn, X, Threads, and Instagram posts plus a designed PDF carousel from that one paste.

Same idea. Two voices. Only one is yours.

Generic tools output predictable buzzwords and robotic phrasing. PrimusPost learns your sentence cadence and vocabulary from writing samples, then writes every post and the carousel in that voice.

PrimusPost Voice-Matched
I spent 2 hours rewriting every AI draft until it sounded like a human wrote it.

Now I drop one raw thought: LinkedIn, X, Instagram, Threads, and a designed carousel, and the copy follows my cadence and vocabulary.

The carousel comes back as designed typography slides, ready to post.

Illustrative side-by-side, written for this page. Your drafts use the voice profile you create in Studio, and your writing is not used to train AI models.

How It Works

One idea in. Five ready-to-post formats out.

Showing up as yourself online shouldn’t be a second full-time job. Three steps, from raw thought to posts you can publish.

  1. Step 01 / Input

    Paste your idea

    Drop in rough bullet notes, a raw opinion, meeting takeaways, or a transcript. No blank page and no prompt writing.

  2. Step 02 / Intelligence

    Match your voice

    Your voice profile, built from posts you already wrote, carries your tone, hooks, rhythm, and vocabulary into every draft and steers away from generic AI phrasing.

  3. Step 03 / Multi-Channel

    Review and post in 5 formats

    Get back a LinkedIn post, an X post, Instagram and Threads posts, and a designed PDF carousel, each ready to copy or download.

The real product, not a mockup

One note about a homepage headline test, followed from the composer to finished posts, a designed carousel and your dashboard.

Drop in a messy thought, a transcript or a PDF. Pick the formats you want and create them all in one pass, written as you.

What one paste makes

One raw thought in. Five platform-native formats out.

No copy-pasting between chat tabs. No formatting by hand. PrimusPost writes all 5 deliverables in your voice from one paste.

“changed our homepage headline last month. old: "AI-powered analytics for modern teams". new: "See which feature your customers actually pay for". demo requests went from 1.8% to 3.1% of visitors in 3 weeks, same traffic. what worked: used the exact words customers said on sales calls, sold the outcome not the tech, cut the page to one CTA. we'd polished features for months when the words were the problem.”

Multi-Slide Carousel Deck

Ready for LinkedIn & Instagram
1.8% to 3.1% demo requests in three weeks. The lift came from the same traffic. We had spent months polishing features when the copy was the bottleneck.
Vague claims hide value. Our old copy sounded like every other software company. It described the tool instead of what the buyer wanted.
Rewriting the homepage copy. Used exact words from sales calls. Sold the outcome instead of the tech. Cut the entire page to one CTA
Sell the outcome, not tech. Pull three phrases from your last recorded sales call and put them in your headline.

The workflow

Separate tools vs. PrimusPost

Stop juggling disconnected tools for drafting, reformatting, and carousel design. One studio, in your voice.

AreaSeparate toolsA chatbot, a design tool, and manual reformattingPrimusPostOne paste, 5 formats, in your voice
Tools and cost
A chatbot for text, a design tool for carousels, and manual reformatting: several subscriptions and a tone that is not yours.
Free to start: 15 generations to use within 30 days, then 3 a month, for all 5 formats in one studio.
Voice
The same tell-tale words ("delve", "game changer", rocket emojis) that readers learn to recognise.
Guided by a voice profile built from your own writing: your vocabulary, sentence cadence, and point of view.
Carousels
Slide layouts nudged into place by hand in a design tool, copying and pasting text slide-by-slide.
Designed 1080×1350 PDF slide decks, laid out for you, with a selectable, searchable text layer.
Repurposing
Copy-pasting across multiple browser tabs, manually editing character limits, posts, and hashtags for each network.
One paste gives you a LinkedIn post, X post, Threads post, Instagram caption, and a PDF carousel.
Time
A recurring weekly chore for drafting, reformatting, and slide layout.
One paste per idea, without the repetitive reformatting.
Privacy
Each consumer chat app sets its own retention and model-training terms, so check them before pasting anything unreleased.
Paid AI services under commercial terms: your content and voice profiles are not used to train AI models.

Simple pricing that scales with you.

Questions, answered.

That is what it is built for. PrimusPost builds a voice profile from posts you have already written (your tone, cadence, vocabulary, and hooks) and writes every draft in that voice. More samples give a closer match, and it keeps learning from the edits you make.

Your next post should sound like you.
