Penbolt: AI Grammar Checker & Translator

Penbolt is an ultra-lightweight grammar checker, writing assistant, and translator extension that never slows you down. It does what Grammarly does, without the weight. WHY PENBOLT? Most grammar checkers and writing assistants scan your page continuously in the background, draining your battery and slowing down your browser. Penbolt does the opposite: it only activates when you select text, and leaves zero footprint otherwise — no background scanning, no resource drain. HOW IT WORKS Select any text on any webpage (Gmail, social media, forums, forms, documents). A small menu appears — choose an action: • Fix — instantly corrects spelling, punctuation, and grammar mistakes • Rewrite — makes your text more professional, fluent, and effective • Translate — instantly translates into any of 13 languages: English, Turkish, German, French, Spanish, Italian, Russian, Arabic, Chinese, Japanese, Korean, Portuguese, Dutch Review the result, and replace your original text with one click. You can also access all three actions from the right-click context menu. WHO IS IT FOR? Anyone who worries about typos in emails Professionals who want to sound polished on social media and in messages Students and academics writing essays, reports, and papers Freelancers and founders communicating in a second language Bilingual users switching between languages daily Anyone tired of Grammarly's weight, price, or constant background scanning A LIGHTER GRAMMARLY ALTERNATIVE Penbolt covers the three most-used features of Grammarly — grammar checking, rewriting, and now translation, which Grammarly doesn't offer at all — in a fraction of the footprint. The core difference: Grammarly runs constantly in the background; Penbolt only runs when you call it. PRIVACY FIRST Only the text you select is ever processed.
