The tutors behind the word-pair rescues.
Tensestutor started with a simple annoyance: the same handful of word pairs kept tripping up good writers, and most explanations online were either too technical or too thin to actually help. So we started writing the answers we wished existed.
What we cover
Affect vs. effect, adviser vs. advisor, truly vs. truely — the mix-ups people actually search for, broken down with clear rules and real examples instead of textbook jargon.
How we write
Every lesson is built the same way: state the rule, show it in a sentence, flag the exception if there is one. No filler, no fluff — just the answer, in a couple of minutes.
Always free
Every lesson on Tensestutor is free to read, with no sign-up required. We're not selling a course — we're just trying to settle the argument in your group chat.
US + UK spellings
Where American and British English disagree, we say so — so you're never guessing which version your reader is expecting.
