What our research says

SEOZilla

Sits a step above the cheapest auto-blogging tools because it names its founders, publishes a credit table you can do arithmetic on, and sells a human-editor tier for people who will not put unreviewed copy on a client site. The syndication to Reddit and Medium is unusual and also the part most likely to get an account flagged if run carelessly. Read the credit costs before the plan names - $19.99 buys about four articles, not a content programme.

Pros

  • Publishes into seven named CMS platforms plus FTP and an API for the rest
  • Credit costs are itemised - 10 to 25 per article by length, 5 per image, 15 per site analysis
  • A human-editor variant of each plan exists for reviewed output
  • Founders are named publicly, which is rare in this category
  • Syndication posts for Reddit, LinkedIn, Medium and YouTube are built in

Cons

  • The $19.99 entry plan is about four articles a month, not a content strategy, and it publishes to WordPress only
  • Extra seats cost $19.99 each on top of the plan
  • The free trial is only three days and asks for a card
  • The pricing page shows Pro at both $99 and $99.99, so the current Pro price is ambiguous

Writesonic

This is not the AI copywriter the catalogs still describe: it is a GEO tracking suite priced like one, and at $79 a month on annual billing you are paying monitoring money for a three-engine view of your own brand. The free plan that used to soften the entry is gone; what is left is a 7-day trial.

Pros

  • Daily prompt and answer tracking is the core of the product, not a bolt-on dashboard
  • Site audits, content generation and the Action Center sit in the same tool as the monitoring
  • 7-day trial with full access and no card, plus a 7-day refund window after paying

Cons

  • Self-serve plans watch three engines out of nine; Perplexity, Claude and Copilot are Enterprise-only
  • Month-to-month costs 25% more than the advertised annual rate ($99 against $79 on Starter)
  • No permanent free plan is listed any more, only a one-week trial
  • Prompt and article caps reset monthly, so a burst of work stalls until the counter resets

Which one fits

Choose SEOZilla if you need

  • Small sites that want four to ten articles a month on autopilot
  • Agencies that need a human editor pass over machine drafts
  • Teams already on WordPress, Shopify, HubSpot or Webflow

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
