What our research says

My AI Ninja

My AI Ninja covers a fairly wide span of marketing content, social posts, blog articles, carousels, and a content calendar, from a single brand profile, which suits a small team without a dedicated content person. The credit system means the different formats are not equally cheap to produce, so a heavy carousel or illustration habit burns through a plan faster than the price alone suggests.

Pros

  • Covers social posts, blog articles, carousels, and an editorial calendar from one brand profile
  • Includes a dedicated LinkedIn post generator
  • Entry paid tier is inexpensive, under $12/month
  • Free trial available before paying

Cons

  • Credit costs differ by content type, so illustrations and carousels use up an allowance twice as fast as a plain social post
  • Pricing is in euros, so US buyers see a converted, fluctuating dollar amount

Writesonic

This is not the AI copywriter the catalogs still describe — it is a GEO tracking suite priced like one, and at $79 to start you are paying enterprise-monitoring money for a three-engine view of your own brand.

Pros

  • Daily prompt and answer tracking is the core of the product, not a bolt-on dashboard
  • Site audits, content generation and publishing sit in the same tool as the monitoring
  • A genuine free tier still exists, with no card required

Cons

  • Starter watches three engines out of ten; the interesting ones are all Enterprise
  • Month-to-month costs about 25% more than the advertised annual rate
  • The old writing-tool positioning is gone, so most third-party reviews describe a different product
  • Prompt and article caps are daily and monthly, so a burst of work stalls until the counter resets

Which one fits

Choose My AI Ninja if you need

  • Small businesses or solo marketers wanting one tool for social, blog, and calendar content
  • Teams wanting brand-voice-matched output without hiring a copywriter

Choose Writesonic if you need

  • Brands that already know they are losing citations inside ChatGPT and want it measured
  • Agencies reporting AI-answer share of voice to clients month over month
  • Teams that want prompt tracking and article production billed on one invoice
