ChatPolish

iPhone-style autocorrect for WhatsApp Web, with a live typo flag, on-demand AI grammar review, and auto-learning from your fixes.

Autocorrect for WhatsApp Web, the way your phone does it. ChatPolish brings iPhone-style autocorrect to WhatsApp Web: instant fixes as you type, help when it isn't sure, and a last check before anything is sent. New in ChatPolish 2.0 One-click AI fixes. Press Ctrl/Cmd+Enter for an AI review, then hit Replace. ChatPolish fixes your message right in the chat box, keeping your line breaks, emoji, and everything that didn't need changing. No more copy and paste. Hover suggestions. Hover over a flagged word to see 2–3 corrections and click one to swap it in. More reliable trials and licenses. Your trial status and license key now survive Chrome updates. Newer Gemini keys supported. Google's new key format works in Settings → Test my key. Your phone's keyboard fixes your typos. WhatsApp Web doesn't, so on a computer every typo goes straight to the person you're talking to. BUILT FOR PEOPLE WHO USE WHATSAPP FOR WORK If WhatsApp is where you send quotes, confirm appointments, and follow up with clients, every message is client-facing. A typo in a price or a patient reminder looks careless. ChatPolish catches it before your customer sees it. WHAT IT FIXES AS YOU TYPE - Typos and missing apostrophes, fixed the moment you finish a word - Checked against a 160,000-word dictionary, and only auto-fixed when there's one clear match, so it never guesses on your behalf - Capitalization: sentence starts and a lone "i" - Spacing: missing spaces after commas get added, and a double space becomes a period, iPhone-style - Made a correction you didn't want? Press Backspace right after it to undo - Learns from you: fixes you choose often become automatic NEW: POINT AT A WORD TO FIX IT When a typo could be more than one word, ChatPolish doesn't guess. It puts a dotted line under it. Point at the word and pick the right one from a small bubble, and it's swapped in instantly. Names and slang you use can be kept as typed with one click. NEW: RIGHT WORD, WRONG PLACE Some mistakes are spelled correctly, so a spellchecker can't see them. ChatPolish catches the common ones from the words around them: "get back yo you" → "to you", "your welcome" → "you're welcome", "better then" → "better than", "its a" → "it's a". NEW: CHECKS BEFORE YOU SEND If a dotted word is still in your message when you press Enter, ChatPolish asks first instead of sending. Fix it with a click, or press Enter again to send as is. You can turn this off in Settings. NEW: LEAVES OTHER LANGUAGES ALONE Writing in Spanish, Portuguese, French, German, or Italian? ChatPolish recognizes it and stops correcting, so your words never get "fixed" into English. Mixed messages still get help with the English parts. ON-DEMAND AI REVIEW For messages that matter, press Ctrl+Enter (Cmd+Enter on Mac) instead of Enter. AI checks grammar, tone, and clarity, not just spelling, and shows you a suggested rewrite before anything is sent. Works with Gemini (free), ChatGPT, or Claude, using your own key. A step-by-step setup guide in Settings walks you through it in about five minutes. PRIVATE BY DESIGN - Regular autocorrect runs entirely in your browser.
