Writesonic uses GPT-4 and proprietary models to generate blog posts, ad copy, and marketing content faster than writing from scratch. It sits between lightweight copywriting tools and full-service agencies, automating the first draft in minutes rather than hours. The differentiator is template-driven workflows tailored to specific content types, which trades flexibility for velocity. Pricing starts free (limited generations), then $13–$67/month depending on volume. The real friction: output still requires human editing and fact-checking, and the free tier runs dry quickly for serious creators.
