About Litero AI

Litero AI is a source-based writing assistant built around a deliberate ethical stance: it positions itself as a partner rather than a substitute, and the product design follows through. Its centrepiece is a citation tool that scans over 100 million sources from legitimate libraries and suggests the most relevant ones for the passage you are writing, so research and drafting happen in the same place rather than in a browser tab you forgot to return to. Around it sit an outline builder that proposes and lets you customise a structure before you write, AI autosuggest for the next sentence when you stall, and a quality-assessment pass that reviews your text against custom criteria and instructions in one click. The integrity tooling is unusually prominent for a writing tool: a built-in AI detector highlights passages that read as machine-generated so you can revise them into your own voice, plus a plagiarism checker, paraphrasing and rewording tools, a text humanizer, and grammar and punctuation checkers. The vendor addresses three audiences directly — content creators, educators and researchers who need to verify student authorship and teach responsible practice, and business professionals streamlining routine writing — and publishes a responsible-use guide alongside the product. Paid access includes unlimited built-in ChatGPT. The free tier is genuinely usable rather than a countdown trial.
