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 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
