The complete AI voice system, built from your existing posts. Ship LinkedIn content that sounds like you, not like every other founder using ChatGPT. Ready in 3 working days. Yours forever, no subscription.
Built for you by Syxo
Three things broke this year for solopreneurs using ChatGPT on LinkedIn.
One. The LinkedIn algorithm got better at detecting AI patterns. Founders who used to post ChatGPT drafts watched their reach collapse. Some report going from 100,000 impressions a month to 5,000 once LinkedIn flagged their AI output.
Two. Your audience can smell generic. Em dashes. "Let's dive into." "It's not just X, it's Y." These patterns broadcast "I didn't write this." And your reputation is what you write.
Three. Writing every post yourself from scratch is 90 to 120 minutes. Shipping consistently means shipping less of your actual work.
Everything that makes your writing unmistakably yours is already in the posts you've shipped. Sentence rhythm. Signature phrases. Openers. What you never say. The AI voice system captures those patterns mechanically, then hands you back a prompt (and a custom GPT) that makes ChatGPT write in your voice instead of its own. You keep the 20 minutes per post to review. You get the 90 minutes back.
Everything below is included. Six main deliverables that solve the stated problem. Nine bonus assets that solve every adjacent problem you'll hit in the next 90 days of posting. No subscription, no lock-in, no recurring fee.
15 to 20-page mechanical breakdown of your last 30 to 50 posts. Sentence length distribution, signature phrases, tone shifts, banned words.
500 to 800 words. Paste into ChatGPT, Claude, or Gemini. The AI writes in your voice for that session. Delivered as .txt, yours forever.
Voice rules, tone matrix, banned words, signature moves. Single reference sheet. Hand to any future writer, VA, or agency.
Generated from the prompt. Raw output, no human polish. You see what the system produces in your voice before you commit.
Your own recent post, rewritten by generic ChatGPT, then by the voice prompt. The contrast between the three is the proof.
10 minute video walking through every deliverable. Voice samples read aloud. Custom GPT demoed live. So the artefact arrives with context.
A fully built custom GPT trained on your writing. Share with your team. Use it anywhere. No prompt pasting required. At most agencies this would be the entire deliverable.
100+ LinkedIn hooks calibrated to your voice. Ready to open any post.
One prompt outputs 30 posts across 5 themes in your voice. Runs in under 10 minutes.
Reply to other creators' posts in your voice. Turns commenting from admin into audience-building.
Turn one post into ten pieces across LinkedIn, X, Instagram, newsletter, and blog.
Step-by-step. A 2-hour session produces 30 days of content. Used by Syxo to run Syxo itself.
Headline, about, and featured section rewritten in your voice with conversion in mind.
Send us your new posts at day 60. We re-tune the prompt based on what's working. Free.
Direct line to our team for 30 days after delivery. Replies inside 24 hours.
Why so much below total value? AI handles 80% of the build time, so the marginal cost of stacking every asset is near zero. We pass the saving to you instead of pocketing the margin. Founder pricing closes once 5 buyers confirm.
| Option | Cost | What you own after | Time to output |
|---|---|---|---|
| LinkedIn ghostwriter | $2,000 to $10,000 per month, ongoing | Nothing. Stop paying, content stops | 1 to 2 weeks |
| Jasper, Copy.ai, Writer | $49 to $99 per month, subscription | Nothing. Generic templates, no voice match | Instant but generic |
| Pressmaster (DIY AI platform) | $29 to $199 per month. Pro tier $708 per year. | Subscription access to the tool. You build the voice yourself. Stop paying, access stops. | Instant platform access. Hours of setup. |
| Freelance writer for voice doc | $1,500 to $5,000 one-off | A voice doc. No system, no GPT, no assets | 2 to 4 weeks |
| Content agency retainer | $3,000 to $10,000 per month | Nothing. Retainer model | 4 to 8 weeks |
| The Voice Build (founder pricing) | $497 one-time (reg. $997) | All 15 assets. Forever. Custom GPT included | 3 working days |
The sharpest comparison: Pressmaster Pro is $708 per year and you do the work. Founder price of $497 is 8 months of Pressmaster. Unlike a subscription, the custom GPT and voice prompt stay yours forever. Cancel anyone else. You will not need to cancel this.
Opened our first conversation with "Not interested if you're trying to pitch me something." He'd switched back to writing manually after LinkedIn suppressed his ChatGPT posts.
We ran the voice system on his last 57 posts anyway, as a demo. His own voice, reverse-engineered.
"I'd love to check out the product when it's ready."
Declined a DIY guide: "I'm still refining my own voice manually." We built the voice analysis from his 13 posts anyway. His own voice, already more defined than he realised, reflected back.
Validation that the system works on small accounts. You don't need 500 posts of training data. Thirteen well-defined pieces are enough.
The opposite shape. A subject-matter expert with extensive content on his website and courses, but near-zero LinkedIn presence. We ran The Content Launch variant on his materials: an expertise audit plus 20 posts in his voice.
Included here to show what the system does when the training data is not on LinkedIn at all.
Named case studies with permissioned testimonials publish May 2026. If you want to see full sample packs from any of these builds before you buy, ask on the intake call.
Day 0. 20 minute call. You share your LinkedIn, the content types you post, three things you want amplified, three things to avoid.
Days 1 and 2. We scrape your last 30 to 50 posts. Run the voice analysis. Build the prompt and custom GPT. Produce all 15 assets.
Day 3. You get the full pack plus the loom walkthrough. 48 hours to flag anything off. We recalibrate. Final files ship. Everything's yours.
After delivery and the 48-hour revision window, if the voice still doesn't sound like you, we refund every penny and you keep every asset. The voice prompt, the custom GPT, the engagement library, the 30-day generator, the brand guide. All of it. No clawback. No clauses.
We're confident enough in the process to eat the cost of being wrong.
One-time payment. No subscription. No lock-in. You own everything.
48-hour revision included. Full refund if voice is off, and you keep everything. Delivered in 3 working days.
Fifteen assets with a total stack value of $5,355. Six main deliverables (voice analysis, voice prompt, brand guide, 10 sample posts, before/after comparison, loom walkthrough) plus 9 included bonuses (custom GPT trained on your voice worth $997 alone, 100+ engagement hooks, 30-day content generator prompt, comment reply prompt, repurposing library, batching workflow, LinkedIn profile rewrite, 60-day voice recalibration, 30 days of private email support). Standard price is $997. Founder pricing is $497 for the first 5 buyers. For comparison, Pressmaster Pro costs $708 per year for DIY platform access.
Three working days from the intake call. Day 0 is a 20-minute intake. Days 1 and 2 are build. Day 3 is delivery with a loom walkthrough and a 48-hour revision window.
The first 5 buyers are founder clients. They pay $497 instead of the $997 standard price in exchange for a written testimonial and permission to publish the build as a named case study once delivered. Once 5 slots fill, pricing returns to $997.
Pressmaster Pro is $59 per month ($708 per year). You still do the work. Jasper trains on generic templates, no voice match. One-time $497 founder price is less than 8 months of Pressmaster Pro, plus we do the build, plus you own the custom GPT and voice prompt forever. No subscription. A LinkedIn ghostwriter at $2,000 to $10,000 per month is a different category of cost entirely.
48-hour revision window is built into the price. If after revision the voice is still off, full refund AND you keep every asset. That's the guarantee. You also see 10 sample posts before you commit.
LinkedIn appears to downrank obvious-AI patterns: em dashes, formulaic structure, hedging language, generic phrasing. The voice system deliberately trains against those patterns using your existing writing. Content produced from the prompt reads like you, not like the model's default voice.
No. The Voice Build gives you the prompt and custom GPT so you (or your ChatGPT) generate content yourself. If you want us to produce content too, The Content Launch ($1,497 founder / $2,997 standard) includes 20 ready-to-post pieces.
Pressmaster Pro costs $708 per year. Jasper costs $600 per year. A LinkedIn ghostwriter costs $24,000 to $120,000 per year. If the voice prompt saves you 10 hours per month on content and your hourly value is $100, that's $1,000 per month recovered. At founder pricing of $497, payback sits around two weeks. Unlike the subscription tools or ghostwriter, you own every asset forever.
Yes. You own it. Paste it into any tool, give it to anyone who writes for you, edit it however you like. The only ask: don't resell the prompt itself as a product.
No. All pricing is USD. Deliverables are identical. Intake call times flex to your timezone.
Twenty minutes. You share your LinkedIn, the content types you post, three things about your voice you want amplified, three things to avoid. We confirm fit, answer questions, invoice sent after. No pitch.
