The Best AI Writing Tools in 2028 (I've Tested Them All)

I've spent a lot of time with AI writing tools over the past two years. Not just playing with them — actually using them to run a content business. Blog posts, product descriptions, email sequences, social media copy. I've tested most of the major players and formed real opinions about each.

Here's my honest ranking and breakdown.

Why AI Writing Tools Matter for Digital Product Sellers

Before the rankings, a quick note on why this matters specifically for people building digital product businesses:

The more content you can produce consistently, the more traffic you attract. More traffic means more potential buyers. And AI writing tools let one person produce the volume of content that used to require a team.

But there's a catch: AI-generated content is only as useful as your editing and strategy. The tools don't replace thinking. They replace the blank-page paralysis and the grunt work of first drafts. Your job is to add judgment, first-person experience, and the things AI can't fake.

With that context, here are the tools.

1. Claude (My Daily Driver)

Claude is my go-to for long-form content. It's the one I find most natural to write with — the outputs feel more human, less formulaic. It handles nuance better than most competitors, and it's particularly good at following detailed instructions about tone and structure.

What I use it for: blog post drafts, product description rewrites, email copy, and any content where voice matters.

Strengths: Natural-sounding prose, good at following complex instructions, strong reasoning for research-heavy content

Weaknesses: Can be verbose if you don't prompt carefully; sometimes overly cautious on certain topics

Best for: Long-form blog content, thought leadership posts, anything where you need a consistent voice

2. ChatGPT (GPT-4o and above)

ChatGPT is still the most versatile tool in the stack. It's not the best at any single thing, but it's good at everything — blog posts, outlines, keyword brainstorming, product ideas, copywriting, analysis. The Plugin/GPT ecosystem also adds functionality that other tools don't have.

What I use it for: brainstorming, quick outlines, editing passes, anything where I need speed over polish

Strengths: Extremely versatile, fastest iteration cycle, great for structured tasks

Weaknesses: Can produce generic-sounding content without detailed prompting; over-relies on common phrases

Best for: Workflows, outlines, structured content, rapid ideation

3. Gemini

Google's model has improved significantly and is worth including on any serious list now. It has an edge in research-heavy content because of its integration with real-time Google search data, and it's strong for creating SEO-optimized structures.

What I use it for: competitive research, topic ideation with current data, SEO outlines

Strengths: Real-time search integration, good for fact-checking against current data

Weaknesses: Writing style is less natural than Claude; sometimes hedges excessively

Best for: Research-assisted content, SEO-focused outlines, current-events pieces

4. Jasper

Jasper was the dominant AI writing tool a few years ago and still has a loyal user base. It's specifically designed for marketing copy — headlines, ads, landing pages, email subject lines. For short-form marketing copy, it's still one of the best.

Strengths: Built-in marketing templates, team workflow features, solid for ad copy and email subject lines

Weaknesses: Expensive for solo operators; long-form content isn't as natural as Claude or GPT-4o

Best for: Marketing copy, teams, anyone who needs structured marketing templates

5. Copy.ai

Similar positioning to Jasper but with a more accessible price point and a simpler interface. Good for beginners who want AI writing assistance without a steep learning curve.

Strengths: Easy to use, affordable, good for quick social posts and short copy

Weaknesses: Long-form quality is average; outputs often need significant editing

Best for: Beginners, social media copy, quick first drafts

The Tool I Don't Use Anymore

I tried several dedicated "AI blog writer" tools that promise to write full posts automatically. I won't name them, but the pattern is the same: the output sounds robotic, lacks personal voice, and needs so much editing that you'd have saved time writing from scratch. I stopped using these entirely.

What Matters More Than the Tool

The biggest leverage in AI writing isn't the tool — it's your prompting and editing. I get dramatically better results by being specific:

• Instead of "write a blog post about Pinterest," I write: "Write a 900-word blog post in first-person, as someone who runs a digital product business, about why Pinterest works better than Instagram for driving traffic to a product store. Include a personal anecdote, 3 specific tactics, and end with a CTA to start today."

Specific inputs → specific outputs. Vague prompts produce vague content.

Turning AI Content Into Revenue

Here's what I've found works: use AI to produce more content faster, then sell that expertise as digital products. Guides, templates, prompt packs — the same skills that make you a better AI writer are things people will pay to learn.

I sell my digital products on MadeThis — it handles the checkout, delivery, and payment processing so I can focus on creating. If you're using AI to produce a lot of content, at some point you'll have enough knowledge and assets to package into something sellable. That's when the income picture changes.

The best AI writing tool is the one you'll use consistently. Start with Claude or ChatGPT, build a prompting habit, and let the content compound.
