No longer a copywriting tool: the tiers are now GTM workflow plans - Chat at the bottom, and Growth/Expansion/Scale sold on an annual commitment only. The old Starter $49 / Advanced $249 tiers are gone.
Still an SEO content pipeline, but the ladder is now Starter/Basic/Growth and the price band moved up a full step - the old Personal $16 / Standard $39 tiers are gone.
Each column came from the vendor's own pricing page: https://www.copy.ai/prices (checked 2026-09-16) and https://writesonic.com/pricing (checked 2026-09-16).
This page is rendered from a data file, so a price change lands here on the next inspection - the one thing a hand-written review cannot do.
