Grammarly Premium costs $30/month. Discover the ultimate Grammarly alternative with full multilingual support and Lifetime Access.
Most grammar checkers hide their best AI features behind a $30/month wall. PowerInput believes that basic writing assistance should be accessible to everyone. If you only need one custom AI command (like for instant grammar and tone adjustment), PowerInput is 100% Free. Forever.
Get Started for FreeWhile Grammarly is a powerhouse for English writing, it often falls short for non-native speakers who need help across multiple languages. Many users are searching for a Grammarly equivalent in Spanish or a Grammarly alternative in French that provides the same level of contextual grammar correction. PowerInput's Bring Your Own Key (BYOK) architecture allows you to harness the world's most advanced LLMs (like DeepSeek V3 and GPT-4o) which offer native-level fluency in 30+ languages.
The biggest pain point with Grammarly is the recurring cost. At $30 per month or $144 per year for the Premium plan, you're essentially paying for a brand name and a massive marketing machine. PowerInput's lifetime deal offers a one-time purchase model. No more monthly billing cycles, just a powerful tool that stays with you forever.
When you pay for Grammarly, a large portion of your money goes toward their Super Bowl ads and YouTube sponsorships. PowerInput is built by developers for developers, writers, and learners. We focus on the core technology: giving you total control over your AI prompts.
If you're tired of the "black-box" nature of Grammarly's AI and want to choose which model handles your text (DeepSeek for logic, GPT for style, etc.), PowerInput is the only choice. Our inline assistant works exactly where you type, without the heavy sidebars or intrusive popups that slow down your browser.
