rewordify.com
Rewrites difficult English into simpler words, keeping the meaning.
Paste a dense passage — a legal notice, a Victorian novel, a research abstract — and it swaps hard vocabulary for plain equivalents, highlighting each change so the reader still learns the original word. It was built for teachers and English learners and comes with reading-level statistics and printable exercises. The substitutions are rule-based, so the prose comes out flat but accurate.
Questions
Works the moment the page loads. No account, no email, no trial. It substitutes vocabulary rather than restructuring, so genuinely tangled sentences stay tangled.
Yes. Rewordify sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
