Before we start, I want to cover the factors that I took into consideration when evaluating these AI tools: 👇

What Factors Should Be Considered When Evaluating AI Tools For Research & Writing

#1: Customization & Trainability

The first and most important factor for me was to find suitable AI tools which are customizable and trainable to produce on-brand content with our writing guidelines.

With generative AI tools that can receive custom instructions, I could enhance my team’s effectiveness and adapt the tools to our needs.

➡️ Most of the tools I’m going to review in this article can be adjusted to your writing style, brand voice and tonality.

#2: Overall Content Quality (How Humane Is The Content)

The second essential factor for me was to find AI tools that generate good content that does not sound robotic.

With the help of humane content-generating platforms, my team could create good quality content that is clear, relevant and not as robotic.

#3: Pricing Structure

The third key factor is the pricing structure of the AI tools you are going to use, so you can be sure it is within your budget.

💡 When I was evaluating AI tools, I looked for transparent pricing structures that provide the needed features and also fit into different budget alternatives.

#4: Optional: Collaboration Capabilities

The final key factor I consider in AI tools when it comes to writing and researching is their ability to help with team collaboration.

I understand that in writing and researching, effective communication is key to getting articles up-to-date and published as soon as possible.

➡️ AI tools can help us work seamlessly with team members while increasing the team’s productivity and engagement.
