Your expertise deserves more
than generated filler.
Plumeum works with you to craft inspiring posts, true to your values and defensible under scrutiny. Neither algorithms nor your readers will mistake them for generic AI content.
Creativity
Original ideas, unexpected angles. The system surfaces fresh perspectives, suggests topics on demand, and helps you develop them — the blank page disappears.
Authenticity
Your voice, your convictions, your expertise. Every post reflects who you truly are — not an average profile, not a generic tone.
Reliability
Different AIs analyse your text and check it for biases, shortcuts and fallacies. What you publish, you can defend.
How it works
Set up your profile
Answer questions about your expertise, convictions and style. Plumeum builds your editorial identity — yours, or the executive or brand you represent.
Generate ideas
The system suggests original angles and topics suited to your field. You choose, you steer — you never face a blank page.
Write and publish
Co-write your post with the AI. A second model verifies the coherence and soundness of your text before you publish.
* AI remains fallible — that is the flip side of its creativity. Always proofread your posts before publishing.
Why publish on LinkedIn when you sell B2B?
Because in B2B, trust is the currency of the purchase — and it is built before the first sales meeting.
of B2B marketers rank trust building as the number one factor in brand success.
of decision-makers find thought leadership more trustworthy than marketing materials for assessing a company.
decision-makers say they are more receptive to outreach from a company that regularly publishes quality content.
Visibility is not enough: it is the credibility of what you publish that triggers trust. And credibility cannot be delegated to a generic content generator — which is exactly why Plumeum co-writes original posts with you, rooted in your convictions and defensible under scrutiny.

Frequently asked questions
What is AI slop on LinkedIn?
AI slop is the generic content mass-produced by AI: interchangeable phrasing, artificial enthusiasm, consensus ideas with no real stance. On LinkedIn, it erodes the credibility of whoever publishes it. Plumeum was built to produce the opposite: posts rooted in your actual convictions, defensible under scrutiny.
How is Plumeum different from ChatGPT for writing on LinkedIn?
ChatGPT writes instead of you, in the average tone of millions of texts. Plumeum starts with an in-depth interview that captures your voice, your positions and your writing rules, then co-writes with you: Claude drafts, you decide, and a second AI checks for clichés and logical soundness before you publish.
Will the content really keep my voice?
Yes — that is the core of the product. Your strategic profile (convictions, style, audience, stances) is injected into every draft. You can add custom writing rules (refused / expected) and import your reference posts to calibrate your natural style.
How does the dual AI validation work?
Claude co-writes the text with you, then a second model (GPT) audits it: clichés, biases, logical shortcuts, fallacies. You publish with full awareness, with a text you can defend in the comments.
Can Plumeum find post ideas for me?
Yes. Emergent ideation puts Claude in dialogue with you to surface non-obvious angles, and real-time exploration grounds your posts in your industry's news.
I never know what to post on LinkedIn — how does Plumeum help?
That's the number one blocker, and it's exactly what Plumeum removes. The app continuously suggests post ideas tailored to your expertise: a personalised idea catalogue, emergent ideation in dialogue with Claude, and real-time exploration of your industry's news. You never start from a blank page: you pick an angle and co-write.
Can Plumeum write for an executive or reflect a company culture?
Yes. The strategic interview captures who you are — or who you represent: an executive, a team, a brand. Posts stay consistent with the company's personality and culture, and the Pro plan manages up to 3 distinct profiles (for example an executive and an employer brand).
Why publish on LinkedIn when you sell B2B?
Because trust decides the B2B purchase before the first sales contact: 94% of B2B marketers rank trust building as the number one factor in brand success (LinkedIn-Ipsos 2025), and 73% of decision-makers find thought leadership more trustworthy than marketing materials for assessing a company (Edelman-LinkedIn 2025). Publishing credible stances regularly builds that trust — provided the content is original and defensible, not generic.
