ghostlio vs Kleo: two different ideas about what authentic means
Kleo builds a deep memory of how you write and what you know. ghostlio asks what you think right now. Both aim to make your posts sound like you. They just start from different places.

Pricing
What you actually pay
ghostlio
- $39/month, or $390/year (save 17%)
- 7-day free trial. $39/month after trial.
- Full AI access on every plan
Kleo
- $99/month ($79/month annual)

Kleo has no free trial. At $99/month you're committing before you've tested it. The 30-day money-back guarantee helps, but it still means putting your card down first. Users report the AI output still needs significant editing despite the voice training; a 3.3/5 Trustpilot rating reflects that gap. ghostlio offers a 7-day free trial before any charge.

The core difference
Why the approach matters
Kleo and ghostlio share a philosophy: the best LinkedIn content sounds like a specific person with specific views, not like a generic professional.
They get there differently.
Kleo builds a model of you over time. You feed it your background, your expertise, your past content. The AI learns your vocabulary, your tone, the way you structure arguments. The more you use it, the better it understands you. It's a long-game approach.
ghostlio doesn't build a model. It asks a question. Right now, about something you just read. Your answer to that specific question is the material the post is built from. There's no training period, from your first session, the output is grounded in what you actually think.
Both approaches can produce authentic content. The difference is how long it takes to get there and what you're willing to pay.
Real results
What happens when the post is actually yours
ghostlio's founder has used the tool daily since February 2026. In the first 90 days:
- LinkedIn impressions increased 1,554% compared to the previous 12 months
- Total impressions reached 209,718
- One post reached 76,051 impressions, 1,742 reactions, 138 comments, and 81 reposts, using ghostlio's Conviction Statement format
- Follower count grew by over 1,000 without any paid promotion
The highest-performing post was built from a single opinion: 17 years of experience distilled into one uncomfortable truth. ghostlio asked the right question. The answer became the post.
Testimonials
Early ghostlio users
“It worked and it worked bloody well. I've teed up a couple of weeks worth of posts, all getting back to basics on on-point messaging.”
“Your system even made me enjoy reading my own thoughts the way it collated them.”
“The interesting part is using AI as an interviewer and extractor for latent opinions people already have but never externalise.”

FAQ
Common questions
What happened to Kleo's Chrome extension?
LinkedIn asked Kleo to shut down their Chrome extension in early 2026 after it was found to be scraping LinkedIn's interface, a terms of service violation. Kleo rebuilt as a web app. The core AI features remain but the extension-based workflow is gone.
Is Kleo worth $99/month?
For serious daily LinkedIn creators who want deep AI personalisation and post on both LinkedIn and X, the single-plan simplicity and voice memory can justify the cost. For most founders and consultants posting on LinkedIn only, ghostlio delivers authentic output at less than half the price.
Does ghostlio build up voice memory over time like Kleo?
ghostlio uses Content DNA, a voice capture completed at setup, rather than a learning model that improves over time. The difference is that ghostlio starts from your current opinion rather than your accumulated history.
