AI can imitate your voice.
It doesn't know what you know.
Posteko writes your LinkedIn and Facebook posts from your client stories, your numbers, your convictions. And when a detail is missing, it asks you for it instead of inventing it.
14 days, every feature, no credit card
The same subject, written with and without your material.
WITHOUT MATERIAL
Artificial intelligence is transforming business. Here are 5 trends to watch in 2026.
WITH YOUR MATERIAL
A client asked me to rebuild their app in 3 weeks. I said no. That no saved them 4 months.
Same AI. Same style. The difference is what you gave it.
An hour for one post. Then three weeks of silence.
You find the angle, you write, you reread, you doubt, you put it off. And when you ask an AI, it hands you competent text that says nothing, so you rewrite half of it, and end up not publishing at all.
Three steps. Thirty seconds for the first.
You give it material.
A story, a number, a client's words, a lesson. Thirty seconds.
Posteko writes from that.
In your language, in your style, and it shows you which material each idea comes from.
You review, you schedule, it publishes.
Through the official APIs.
Posteko also publishes to your Facebook Pages (posts, Reels and Stories) and surfaces your reactions and comments.
Why you can verify it
- The source appears on every idea, verified server-side
- "[À COMPLÉTER]" rather than an invented statistic
- 35 banned AI phrasings, checked after generation, not just requested
- Native French: the app, the writing, the support
- Official LinkedIn and Meta APIs: no extension, no bot logging in on your behalf
- Built by someone who publishes with it, every week
It doesn't sound like ChatGPT. It sounds like you.
Posteko combines your work, your goals, your audience and your style, then learns your voice as you publish. Give it your raw material (a note, a client quote, a lesson learned) and your posts start from that. With nothing to give it yet, it starts from your profile.
Your voice, not a template
Sharpens with every edit · French, English and Malagasy
Written, scheduled, published in one place.
Your LinkedIn and Facebook posts go out at the time you choose, through the official APIs. Posteko retries on its own if the platform doesn't respond, and lets you know if it can't.

Automatic retry, and an email if the failure persists
One session on Monday. Published all week.
Lay out your calendar in one go. Posteko publishes on time, and retries on its own when a platform doesn't answer.

You sell what you know.
Consultant, specialised freelancer, independent expert. Your credibility is your offer, and your posts should contain what only you have lived.
I built Posteko because I was losing entire afternoons to a single post. Existing tools knew how to write in my place. None of them knew what I had actually lived through the week before.

Frequently asked questions
What is Posteko, exactly?
A tool that writes your LinkedIn and Facebook posts from your material (your customer stories, your numbers, your convictions), then schedules and publishes them through the official APIs.
How is this different from ChatGPT?
ChatGPT starts from scratch every conversation, keeps no record of your customer cases, will write "90% of executives…" without blinking, and publishes nothing. Posteko keeps your material, refuses to invent a number you didn't give it, shows you where every idea comes from, and publishes at the time you chose.
Does the content sound like AI?
Posteko writes from what you give it (your stories, your numbers, your phrasing) and rejects the turns of phrase that give away an AI, through a list of banned phrases checked after generation. And you always review it before publishing.
What if I don't have material to give it?
It starts from your profile and your goals. But let's be direct: Posteko is built for someone who has specific things to say. If you don't, a generic generator will cost you less.
Which platforms?
LinkedIn and Facebook Pages, including Reels and Stories. More networks are coming.
Do you show LinkedIn analytics?
Facebook Page metrics (reactions, comments and shares) are pulled in automatically. LinkedIn analytics are not: LinkedIn only opens post metrics to partners approved for its Community Management API, and we don't have that access. Everything else (writing, scheduling, publishing) works identically on both networks.
Is my account at risk?
No. Posteko publishes through the official LinkedIn and Meta APIs, with the permissions you grant and can revoke at any time. No bot logs in as you, no browser extension. It's the only method the platforms allow.
What does it cost?
€29 a month, or €290 a year. The trial lasts 14 days, every feature is open, no credit card is required. The first 20 customers keep €19/month for life.
Why no free plan?
Because what makes Posteko useful (giving it your material, seeing the difference) doesn't fit in a capped plan. The trial lasts 14 days, everything is open, no card is required.
Is my data safe?
Your data is encrypted and never sold. You can export or delete it whenever you want.
