What is Smodin?

AI detection, humanising and plagiarism checks for writers.

Who is Smodin best for?

Smodin is best for students and content writers who check drafts for plagiarism and AI text before submitting.

  • Students checking their own work

    The plagiarism checker scans web and academic sources, and the AI detector marks sentences that read as machine-written before an essay goes in.

  • Content writers who draft with AI

    The humanizer and rewriter turn stiff AI drafts into a more natural voice, and the writer and chat help with outlines and first drafts.

  • Writing in a second language

    The tools work in 100 languages, and the translator and rewriter help tidy up drafts written outside your first language.

  • Job seekers

    The career toolkit drafts cover letters and runs practice mock interviews, and the first mock interview is free without signing up.
