4.5 out of 5
Scored by a Toolio reviewer after real useOur verdict
Walles.AI puts a GPT-4-powered sidebar on every website, translating or explaining selected text, summarizing YouTube videos into quick outlines, and chatting with uploaded PDFs. It's built for students and researchers who want to process video and document content faster rather than watch or read everything in full. In-app purchases are offered, so some capability likely sits behind a paid tier, and it runs only as a Chrome extension with exports tied specifically to Notion.
