Hey Product Hunt and fellow creators on LinkedIn 🤗
My content creation went from an hour of struggle to 5minutes.
Here's my story.


😬 The old way (2024):


- Wake up at 6am.
- Stare at my Apple Notes ideas for 30 minutes
- Write something, delete it, repeat
- Rush a rough draft through Claude at 7am
- Post out of desperation at 8am, never fully satisfied.


I had ideas from client conversations and team discussions, but turning them into compelling stories? That's where I'd get stuck for hours.
Most AI writing tools promise to solve this, then make everyone sound the same.
That's exactly why we built Syndy.ai:
"It's Grammarly for LinkedIn that preserves YOUR voice."


😎 Here's my new process (2025):


- 5 minute brain dump on Syndy with my raw ideas.
- Co-write together with Syndy. It suggests angles, narrative structures, and formats.
- 2 minutes first draft, 3 minutes editing.
- Read out loud (now I have time for this!).
- Post with confidence.


Now I get content I'm actually proud of in minutes. I went from rushing through my commute to listening to podcasts in peace (all thanks to that extra hour).


Here's how Syndy works:
→ Learns your unique voice from your previous posts.
→ Transforms fractured ideas into full posts that sound like you
→ Suggests multiple angles for your stories
→ Preserves your quirks and tone (Not sounding like bot with tech bro glasses)


Smash that upvote if you're tired of the an hour long writing struggle.
Your voice is what makes you.


Let's keep it that way, but a little smarter. 🤙

@ed_choi_7 Still getting used to how the editor works, but the suggestions are better than what I’ve seen from other AI tools. Do you plan to train Syndy on my previous LinkedIn posts over time?

Thanks so much for the kind words! Yes, one of our core goals with Syndy is to continuously learn from your writing over time. In fact, the current version already learns from your past LinkedIn posts to better reflect your tone, structure, and phrasing as you continue using it. Yet, even this could be automated!

Review Syndy.ai?

Syndy.ai is praised for its ability to enhance LinkedIn content by maintaining the user's unique voice while improving clarity and engagement. Users appreciate its nuanced handling of CTAs and the standout "LinkedInize" feature. The tool's focus on user control and simplicity is highlighted, with no forced writing styles or complex onboarding. While some users express interest in multichannel capabilities, the current LinkedIn-specific design is seen as a strength. Overall, Syndy.ai is valued for its practical, user-friendly approach to content creation.

Great overall, but I did get a bit confused on how I had to use the custom prompt tool. Sometimes I wasn’t sure where to type what, especially when I wanted the AI to take the lead vs. just help. Maybe a quick tooltip could help?

Thanks so much for the thoughtful feedback!

We hear you! Our product team is already exploring how to make the custom prompt tool more intuitive including adding tooltips and clearer guidance for when the AI leads vs. supports.

Really appreciate you calling this out. This helps us improve faster. If you have any specific moments that felt confusing, we’d love to hear more!

“It didn’t just save me time” – My Honest Review of Syndy I started using Syndy to draft some LinkedIn content, expecting it to simply save me time. And yes, it did that — but it also did so much more. What truly blew me away was its ability to turn a plain opening sentence into a powerful hook. With just a few tweaks, Syndy transformed my intro from “just okay” to genuinely engaging — the kind that makes people stop scrolling. It felt like having a seasoned content editor sitting next to me, whispering, “Here’s how to make that stronger.” Sure, the overall writing time was cut down, and the tone-matching feature was impressive too. But what stood out the most was how Syndy elevated the quality of my writing in ways I didn’t expect. It didn’t just polish the surface — it reshaped the flow and made everything sharper. I can easily see this being useful not just for LinkedIn posts, but also for newsletters, blog drafts, or anywhere I need to write quickly without compromising quality. If you’re looking for a tool that goes beyond time-saving and actually helps you write better, Syndy is absolutely worth trying.

Thank you so much for this thoughtful and honest review.

We’re especially glad to hear that Syndy went beyond your expectations and didn’t just save you time, but actually helped elevate your writing.

We’re continuing to fine-tune the editor based on feedback like yours, and your point about its usefulness beyond LinkedIn (like newsletters or blog posts) is spot on. While we are not completely sure at what point we will transition to a multichannel platform, it is something we are definitely going to do.

I’ve tried many AI writing platforms before, but it was my first time using one that’s specifically tailored for LinkedIn. The hook generation feature was especially helpful, making it much easier to start a post with impact. Its context expansion capabilities allowed me to develop brief ideas into more structured and engaging content. I also appreciated the layout refinement feature, which made my posts more readable and visually balanced. The interface is clean and minimal, and the overall flow is intuitive enough for anyone to get started right away. I found the real-time preview of how the post would appear on the LinkedIn feed to be incredibly useful. It felt less like a writing tool and more like a content partner that understands how personal branding works. Syndy strikes a great balance between professional quality and ease of use—definitely worth trying.

It’s especially encouraging to know that features like hook generation, context expansion, and layout refinement stood out to you. Commonality between users is that they really like the hook feature!
