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

Plainpaper

Plainpaper's pitch is that campaign work should live on a persistent board instead of scrolling away in a chat thread, and the card-based layout plus direct integrations with email and ad platforms back that up. At $31-plus per month for a single workspace, it competes with both AI copy tools and full marketing platforms, so the value depends on whether a team actually wants the board format.

Pros

  • Campaign drafts persist as reviewable cards instead of disappearing in a chat log
  • Connects to MCP clients (Claude, ChatGPT, Cowork) and to Klaviyo, Shopify, Mailchimp, Meta Ads, and Canva
  • Every plan includes a seven-day free trial with no card required

Cons

  • Entry plan caps out at one workspace and one user
  • Pricing is billed in euros, so the exact USD cost moves with the exchange rate
  • No standalone public API beyond MCP client connections
