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 layout plus direct links to email and ad platforms back that up. The free plan with two boards is enough to run one real campaign end to end, and Starter at $19 a month is cheap next to full marketing suites; 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
  • A free plan with two active boards and no time limit, then paid tiers from $19 a month

Cons

  • Entry plan caps out at one workspace and one user
  • Paid tiers differ only by workspace, user and board counts, so a growing agency jumps from $19 straight to $79 a month
  • No standalone public API beyond MCP client connections
