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.
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.
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.
Showing up as yourself online shouldn’t be a second full-time job. Three steps, from raw thought to posts you can publish.
Drop in rough bullet notes, a raw opinion, meeting takeaways, or a transcript. No blank page and no prompt writing.
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.
Get back a LinkedIn post, an X post, Instagram and Threads posts, and a designed PDF carousel, each ready to copy or download.
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.
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.”
We spent months polishing product features when the words on the page were the real problem. Last month I changed our homepage copy. Our previous headline was generic: "AI-powered analytics for modern teams." It described the mechanism, but gave the visitor no clear reason to care. I swapped it for the concrete result buyers kept bringing up: "See which feature your customers actually pay for." We did not redesign the interface or buy more ads. We only cut the layout down to a single call to action and led with the actual job buyers wanted done. In three weeks, demo requests went from 1.8% to 3.1% of visitors on the same traffic.
We changed our homepage headline from "AI-powered analytics for modern teams" to "See which feature your customers actually pay for". Same traffic. Demo requests went from 1.8% to 3.1% in 3 weeks.
your.handle Our homepage copy sounded smart, but nobody booked a walkthrough. Last month I went through our sales calls and pulled the exact phrasing buyers kept repeating. We stripped the fluff and boiled the hero section down to one clear outcome: finding out what customers will open their wallets for. Then we deleted every competing link and kept just one CTA. Nothing in the underlying software changed. But across three weeks, demo requests climbed to 3.1% from 1.8% on identical traffic. #copywritingtips #saasgrowth #conversionrateoptimization #b2bmarketing
Founders love pitching tech over outcomes. We talked about AI analytics on our site for months while visitors ignored it. Once we marketed the end payoff instead of our tools, the headline rewrite lifted demo requests to 3.1% from 1.8% in 3 weeks.
