ChatPolish

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

ChatPolish brings iPhone-style autocorrect to WhatsApp Web — the same instant, invisible fixes you're used to on your phone, right in your browser. WHAT IT DOES Fixes common typos and missing apostrophes the moment you finish a word — no need to notice them yourself Catches other typos too, checking against a 160,000-word dictionary (only auto-fixes when there's exactly one likely match, so it won't guess wrong) Auto-capitalizes the start of sentences and a lone "i" Turns a double space into a period, iPhone-style ("done " → "done. ") Fixes missing spaces after commas Flags repeated words, ALL CAPS, and ambiguous typos in a small on-screen banner as you type — nothing sent anywhere, purely local Learns from your own repeated corrections and adds them to your personal dictionary automatically ON-DEMAND AI REVIEW (OPTIONAL) Press Ctrl+Enter (Cmd+Enter on Mac) instead of Enter on a message that matters, and your chosen AI checks it for real grammar, tone, and clarity issues — not just typos — before you send. This is entirely opt-in: nothing is sent anywhere unless you use the shortcut, and you bring your own API key from the provider you choose (Claude, ChatGPT, or Gemini). ChatPolish never sees or stores your key or your messages — it's a direct connection from your browser to your chosen provider. PRIVACY ChatPolish runs only on web.whatsapp.com. Your messages are never sent anywhere for regular autocorrect — everything happens locally in your browser. The only exception is the optional AI review above, and only when you actively trigger it. PRICING Free for 7 days, then $3/month or about $25/year. Your license key works across every device you use ChatPolish on — no separate purchase needed per computer.
