Let’s be real: trying to create great content all the time is tough. It can feel like a content treadmill you can’t get off. AI writing tools have popped up to help take some of that weight off your shoulders. This guide will walk you through the top tools for different jobs, whether you’re in marketing, SEO, or handling business communications, so you can find the one that actually fits your workflow.
What is an AI tool in writing?
At its heart, an AI tool in writing is a specialized app that uses a Large Language Model (LLM) the same tech behind chatbots like ChatGPT and Claude. But here’s the important difference: unlike those do-it-all bots, these tools are fine-tuned for specific writing jobs.
Think of it this way: ChatGPT is like a giant library with every book imaginable, while a dedicated AI writing tool is the librarian who knows exactly which book (or template) you need. Whether you’re trying to draft a blog post, come up with some catchy ad copy, or write customer support replies, these tools are built to help you get it done faster and with less hassle. They’re not meant to replace human creativity, but to work alongside it.

The 9 best options for an AI tool in writing for every need in 2025
Now, let’s get into what makes each of these tools a solid choice.
1. eesel AI: the best AI tool in writing for customer support and internal teams
Most AI writing tools are all about marketing content. eesel AI goes a different route, focusing on a really important area: business communications. It’s an AI platform made for customer support and internal teams, acting as a smart layer over the tools you already use every day.
The secret sauce for eesel AI is where it gets its information. Instead of training on the generic web, its AI Copilot and AI Email Writer learn from your company’s own private knowledge. It connects to your help desk (like Zendesk or Freshdesk), your past support chats, and your internal wikis in Confluence or Google Docs. This means it can generate draft replies that are incredibly relevant, factually accurate, and already in your brand’s voice. A general-purpose tool just can’t compete with that. The best part is that it works right inside your current software, so you don’t have to switch to a new system.
Pros:
-
Suggests drafts based on your own business data, making them super relevant.
-
Works directly inside the help desk and chat tools you already have.
-
Helps new agents get up to speed faster and makes the whole team more efficient.
-
Keeps your brand voice consistent and accurate in every customer interaction.
Cons:
-
It’s focused on support and internal teams, so it’s not for general content marketing.
-
The price is higher than beginner tools, as it’s built for business use.
Pricing: Starts at $239/month (billed annually) for the Team plan, which covers up to 1,000 AI interactions.

Pro tips: how to get the most out of your AI tool in writing
Picking the right tool is only half the battle; how you use it makes all the difference. Here are a few tips to get better results:
-
Be specific with your instructions. The more context you give the AI, the better the output will be. Don’t just ask it to "write a blog post about dogs." Instead, try: "Write a friendly, 500-word blog post for new dog owners about the top three essential items they need to buy." Mention the tone, audience, and key points you want to cover.
-
Use it as a partner, not a replacement. The best way to use AI is for getting a first draft down, brainstorming ideas, or pushing past writer’s block. You should always add your own expertise on top. You’ll need to edit, check the facts, and add your own voice to make the content feel authentic.
-
Train it on your own voice and knowledge. For business use, getting the AI to sound like you is key. The real power comes when the AI learns from your team’s existing work. This is where a platform like eesel AI really stands out for support teams. It learns from thousands of your past support tickets and internal docs to make sure every reply it suggests is accurate and captures your brand’s tone.
-
Tweak and refine your drafts. The first version the AI spits out is rarely the final one. Use the tool’s features to rewrite, expand, or shorten the text. Play around with it until the content says exactly what you want it to.
Finding the right AI tool in writing for the job
At the end of the day, the "best" AI writing tool is simply the one that fits what you need to do. General-purpose tools are great for many marketing and creative tasks, but specialized business work often requires a specialized tool. For high-stakes writing like customer support or internal documentation where accuracy, context, and brand voice are everything a platform built for that specific job is your best bet.

Frequently asked questions
Reputable tools generate original content, but it’s a best practice to run the final text through a plagiarism checker. This helps ensure your content is unique, especially for important SEO or academic work.
Yes, advanced tools can do this well. While some offer generic tones, platforms like Jasper let you create detailed voice profiles, and tools like eesel AI learn your brand voice directly from your team’s past writing for the most authentic results.
You should always edit the output. Think of the AI as a creative partner that produces a solid first draft, but your human expertise is essential for fact-checking, refining the tone, and adding the final polish that makes content great.
It depends on your goal. Free tools are great for brainstorming, but a paid, specialized tool offers workflows and features designed for specific tasks like marketing or sales. This focused design often saves time and produces higher-quality, targeted content with less effort.
Security varies, so always check the provider’s privacy policy. Enterprise-focused tools like Writer and eesel AI prioritize security, ensuring your private data isn’t used to train public models and often offer stricter data-handling protocols.
First, clearly define the specific problem you want to solve, whether it’s creating blog drafts faster or improving support ticket responses. Choosing a tool designed for that exact use case will deliver the best results and make adoption much smoother for your team.
