Did You Mean? от Jonathan Goldner

Catches your personal atomic typos in Gmail — real words used in the wrong context that spell check misses. These real-word errors and word substitutions are invisible to standard spell checkers because every word is technically valid. You typed "beset" when you meant "best." You wrote "Greta" when you meant "great." Autocorrect won't save you. Did You Mean? will.

Build your own personal dictionary of up to 8 trap words. When you're composing in Gmail, the extension flags each one with a gentle "did you mean?" nudge — no auto-replacement, ever. You decide.

Works across English, Spanish, Italian, Portuguese, and other Roman alphabet languages.

Keywords: atomic typo, real-word error, word substitution error, context-aware spell check, Gmail proofreading, email typo checker, homophone error, personal spell check, typing habits, compose assistant.
