How is TypoGrammar different from Grammarly or Duolingo?

Grammarly fixes your sentences but rarely teaches the underlying rule. Duolingo gamifies short drills. TypoGrammar focuses on understanding - every lesson explains why a structure works, with examples, mistakes to avoid, and a quick quiz to lock it in.

How long does it take to see results with TypoGrammar?

Most learners report a noticeable improvement in writing accuracy within 2-3 weeks of daily 15-minute sessions. The verb-tenses quiz gives you a personal weak-area breakdown, so you can target exactly the tenses you keep getting wrong.

Can I use TypoGrammar on my phone?

Yes - the entire site is mobile-first. Lessons, quizzes, and the grammar checker all work in any modern mobile browser. There is no app to install.

What is the difference between affect and effect?

Can effect be a verb and affect be a noun?

Yes, but rarely. 'Effect' can be a verb meaning 'to bring about' (to effect change — meaning to cause change to happen). 'Affect' can be a noun in psychology meaning an emotional state. For most everyday writing, treat affect as a verb and effect as a noun.
