What our research says

Copy.ai

Worth it if you are a go-to-market team that will actually build workflows; if you just want a writing assistant, the free plan is gone and a general chatbot costs less.

Pros

Workflows chain research, enrichment and writing instead of one-shot prompts
Chat seats are unlimited-word and cover five users at the entry price
Now backed by a larger RevOps suite rather than a standalone startup

Cons

Entry price climbed as the product moved upmarket away from individuals
Nothing exists between the $29 Chat seat and the $1,000/mo Growth tier
Workflow credits meter compute, so running cost is hard to predict up front
Roadmap now serves Fullcast's revenue-operations story, not writers

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
