Why We Killed Grammarly
Grammarly turned spell-check into a $144/year subscription. Every word you type flows through their servers. Every email, every document, every private message—analyzed, stored, and used to train their models. You’re not just paying for grammar fixes; you’re paying to be their training data.
The “freemium” trap is real: basic spelling works, but the moment you want clarity suggestions, tone detection, or plagiarism checks, you hit the paywall. And for teams? $180/seat/year. A 10-person company pays $1,800 annually for what should be a solved problem.
Our AI analyzed Grammarly’s entire feature set and rebuilt it from scratch in 38 hours. With local LLM support, your writing never leaves your machine.
