What our research says

Frase

The brief builder is still the reason to buy it — pulling competitor headings and questions into a usable outline in a minute — but the article and audit caps are tight enough that the entry tier suits one writer, not a content team.

Pros

  • SERP extraction into a structured brief remains fast and genuinely useful
  • API and MCP access are included on every plan rather than being an upsell
  • Direct publishing to WordPress, Webflow, Sanity and Wix removes the copy-paste step
  • Now scores against AI answer engines, not just Google rankings

Cons

  • No free tier and a short 7-day trial
  • Monthly billing costs about 25% more than the advertised annual rate
  • Article, audit-page and Content Guard caps are all separate meters to track
  • Extra seats at $29/month add up quickly on a 3-seat plan

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 Frase if you need

  • Writers and small agencies who want a research-backed outline before drafting
  • Teams tracking whether published pages are decaying in both Google and AI answers
  • Anyone who wants brief, draft and publish in one tool

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
