FenPost is an AI-powered LinkedIn content creation tool built to help professionals, creators, and founders post consistently, confidently, and without stress.

Most people know they should be showing up on LinkedIn regularly, but few have the time or energy to do it well. Crafting great posts takes hours of brainstorming, editing, and second-guessing. That’s why so many give up or disappear after just a few attempts. FenPost exists to solve that exact problem.

Created by two founders who experienced the same struggle, FenPost was born out of a simple but powerful idea: posting on LinkedIn should be easier, faster, and more effective. Unlike generic AI writing tools, FenPost is built specifically for LinkedIn. Every feature is designed with platform-native content and real user challenges in mind.

FenPost helps you generate LinkedIn posts that sound like you, not like a robot. It allows you to test different hooks and rehooks, so you can find the most engaging angle without guessing. You can also create structured carousel content, write short video scripts, and generate thoughtful first comments that increase your reach and spark conversation.

What sets FenPost apart is its focus. It doesn’t try to write every kind of content or serve every platform. Instead, it does one thing exceptionally well, LinkedIn. The tool is simple, clean, and fast, with a distraction-free interface and just the right amount of smart support.

Even more important, FenPost is being built with and for the community. Feedback directly influences development, and every update is driven by real user needs. You’re not just using a tool, you’re helping shape it.

If you’ve ever stared at a blank screen or spent hours editing a single post, FenPost is here to change the way you approach LinkedIn. We believe your ideas matter, and sharing them should feel easy.

Start creating with less stress and more impact. FenPost is just getting started, and we’d love for you to be part of the journey.

It’s designed to make sharing your voice easier, faster, and more rewarding.

Which are the primary technologies used for building your product?

FenPost's answer:

ChatGPT Reviews

  1. my personal assistant at work

    I recently acquired access to ChatGPT, one of the most advanced language models out there, and I must say it has made a significant impact on my analytics work. It has definitely become an integral part of my daily use.

    Analytical support: ChatGPT does a great job of providing accurate and timely answers. It can also help me analyze large amounts of data. Efficiency: This product allows me to work more efficiently by using it to quickly find information or get recommendations.

  2. Word.Studio
    · Editor at Word.Studio ·
    The essential AI everything tool.

    OpenAI continues to lead the way among the foundation model providers. I started using ChatGPT at 3.5 much like many other people. And although it was extremely powerful, it doesn't compare to what it has become with the new reasoning models like o1 and o3. These models produce outputs that are on a new level in terms of quality.

    I've been using custom GPT's extensively and they are very valuable once you get them dialed in to your own specific workflows. they recently rolled out projects which also have the ability to add custom instructions. Many of the custom GPT's that I've made do not need anything other than custom instructions. They don't need Web hooks or documents to reference, so a project will suffice. projects also allow connecting and switching between some of the newer reasoning models as well while custom GPT's are limited to the 4o model.

    Real time voice assistant is a game changer when you are on the go. And the human-like speech synthesis is incredible. uploading photos and giving the voice assistant access to live video from your phone has so many use cases that I have yet to realize.

    Many of the tools we have on WordStudio are powered by the OpenAI family of models via API. We recently hooked some of the tools to their o1 model and the improvements in the outputs are astounding.

    I've tried Anthropic's Claude and have experimented with DeepSeek, but I keep returning to ChatGPT for critical work.

    🏁 Competitors: Claude by Anthropic, Deepseek R1, Llama
    👍 Pros:    Active development|Powerful models|Api & webhooks|Multi modal|Canvas mode for long-form content and code|Text, image + video generator
    👎 Cons:    Image generator is lacking|Organization of chats is cumbersome
  3. WOW!One love

    My journey with GPT-4 as a novice programmer has been nothing short of remarkable. I used it to write a game, and despite my limited programming knowledge, I was astonished by the results.

    It makes coding suggestions, completes my code, and even identifies bugs, which has been a game-changer for me. It feels like having a co-programmer who anticipates my needs and guides me in the right direction.
