AI Language — 28 Free Online Tools
Translate, paraphrase, detect AI-written text, cite sources and build resumes with AI. Multi-model fallback keeps every tool answering.
Everything here calls a model, so treat the output as a draft and check arithmetic, citations and quoted sources before it goes anywhere public. The Translator, Sentence Rewriter and Paraphrasing Tool all show the before and after side by side, the Citation Generator formats APA, MLA and Chicago from details you supply rather than inventing a source, and the ATS Resume Checker scores a resume against the parsing rules employers actually use.
