How to choose the right AI writing tool

The ideal AI-writing tool fits into your existing workflow, moves you toward your content creation goals faster, and feels simple to use. Think about your specific needs, who can benefit, and which writing tasks AI tools can help with as you determine what will work best for your organization.

Step 1: Define your specific use case

Take a look at how often you will be using the AI writing tool. Are you trying to scale content production and implement a solution that increases daily written output? Or is this a tool for occasional convenience?

Then consider how you will use your AI tools. Are basic answers pulled from a knowledge base sufficient? Or do you need to program your company’s voice and expertise for detailed, branded content creation that’s publish-ready? Advanced AI writing tools can be fine-tuned and taught your company’s lingo, tone, style guide, and inventory.

Step 2: Consider who on your team could use AI and how

If your business handles its creative assets in-house, has an engaged C-suite that participates in content ideation, and partners with external writers, consider adding AI tools for content creation to your tech stack. Some AI tools offer collaboration for multiple users, while others cater to individuals.

• Departments. It’s common for members of marketing, sales, internal communication, product development, and creative teams to focus on producing publish-ready writing for the company website, product packaging, emails, and more. AI-writing tools speed up the process while offering aligned generative language to get creativity flowing.
• Solo creators. Upper management professionals use AI-writing tools to polish their thoughts and produce well-constructed memos, emails, and ideas to bring to their teams.
• Contractual help. If you’re investing in company-wide AI tools, extend an invitation to your freelance creatives to use them also. The additional productivity and brand adherence these tools offer mean more efficient collaborations and fewer contract hours billed.

Step 3: Understand the writing tasks AI tools can tackle

Choose AI tools that align with your common business writing tasks. Here’s a sample of items that creative employees work on regularly and that AI writing tools can help with:

• Articles
• Blog posts
• Content briefs
• Contracts
• Emails
• Guidelines
• Landing pages
• Meeting agendas
• Meeting summaries
• Memos
• Newsletters
• Press releases
• Product packaging
• Project bids
• To-do lists
• Training materials

For example, if you’re an estimator with a home builder who generates project bids weekly, your sales team can use AI business tools to quickly search your company’s knowledge base and retrieve data about specific home models, pricing, project materials, and current service timelines to generate documents that educate potential home buyers.

How to use AI writing tools with Slack
