TypoGuard 是什么
Free AI spell check as you type — catch spelling mistakes in Gmail, Outlook, ChatGPT and every other website. TypoGuard catches misspelled words as you type — in any text field, on any website.
It runs an AI spell check on what you are actually writing, underlines real spelling mistakes with a red wavy line, and fixes them in one click. No copy- pasting into another tab, no rewriting your sentence.
WHAT IT DOES
- Spell-checks text fields, textareas and rich-text editors as you type
- Underlines misspelled words — click one to see suggestions
- One click replaces the word in place, exactly where it was
- Detects your language automatically — nothing to configure
- Optionally turns off your browser's own spell check so you don't get two
sets of red underlines on the same word
- Switch it off per site, or everywhere, from the options page
展开其余商店介绍▾
WHERE IT WORKS Any text field on any website — webmail, chat interfaces, comment sections, forms, and the everyday text boxes you already use, including popular rich-text editors.
WHAT IT DOES NOT DO — ON PURPOSE
- It never reads password fields. Password, credit card, CVV, OTP and PIN
inputs are excluded by input type, by autocomplete attribute, and by field name, before anything is read.
- It never reads the rest of the page. Only the single field you are actively
editing.
- It does not store what you type. Your text is sent over HTTPS to our
backend, passed to the AI model, and discarded as soon as the correction comes back. It is never written to disk.
- It corrects spelling — not grammar, punctuation or writing style. It will
not rewrite your sentences or change your voice.
PRICING
- Free: 100 corrections per month. The first 30 work straight after install;
after that you connect a free Google account so your remaining corrections follow you between browsers and survive a reinstall.
- Premium: $6.99/month or $49.99/year — 5,000 corrections per month.
PRIVACY No ads. No tracking pixels. Nothing sold to anyone. We keep an anonymous installation identifier so we can count your free corrections, and that is it. Full policy: https://typoguard.vip/privacy-policy/
