A Chrome extension and Google Docs add-on bring scanning into Gmail, Docs, Classroom, and other surfaces you already work in.
Checks content for copied passages from outside sources so you can separate AI-generation questions from originality questions.
Sum up any webpage or video in one click, tuned to the length, tone and language you want
Read any webpage or video and get a concise summary in under a minute, right on the page you are viewing.
Set the length, tone and perspective of a summary so the output matches whether you want a quick gist or a structured brief.
Receive summaries in your preferred language, useful when you read across languages or want consistent output.
