What Is Writesonic?
Writesonic is an AI-powered content creation platform founded in 2020 and used by over 10 million users worldwide. It’s built on GPT-4o and proprietary models, and is best known for three things: its long-form Article Writer 6, its Chatsonic interface (a ChatGPT alternative with real-time internet access), and its affordable pricing.
For affiliate marketers, Writesonic hits a sweet spot: it’s powerful enough to produce publishable SEO content, yet cheap enough that you don’t need a single affiliate commission to justify the cost. And it runs one of the most generous affiliate programmes in the AI tools space — 30% recurring commissions with a 90-day cookie window.
Writesonic Key Features
- Article Writer 6: Enter a keyword, choose your outline, and get a full-length SEO-optimised blog post (1,500–3,000+ words) in minutes.

- AI Image Generation: Built-in image creation powered by DALL-E and Stable Diffusion — no separate Midjourney subscription needed.

Writesonic Article Writer 6 — Does It Work for Affiliate Content?
We tested Article Writer 6 extensively for affiliate marketing use cases. Here’s our honest assessment:
The Process
- Enter your target keyword (e.g. “best AI writing tools for bloggers”)
- Writesonic generates 5 title options — pick the strongest
- Review and customise the AI-generated outline (H2s and H3s)
- Choose your content quality setting (Premium uses GPT-4o)
- Click Generate — full article ready in 60–90 seconds
Our Results
In our tests, Article Writer 6 produced a 2,500-word affiliate review post in approximately 4 minutes, including time to review the outline. The output included a proper introduction, multiple H2 sections, a comparison table, pros/cons, and a conclusion with CTA — essentially the full structure you’d write manually.
The content quality was solid for GPT-4o output: factually reasonable, well-structured, and free of obvious errors. However, like all AI tools, it lacks personal experience and specific case studies — you’ll want to add those before publishing to pass Google’s helpful content evaluation.
Pro tip: Use ChatGPT to enrich your Writesonic output with personal anecdotes, specific pricing details, and real screenshots before publishing. And use Surfer SEO to optimise your content score before hitting publish.
