Our Verdict

SummarizePro wins for pure summarization. Its 8 modes, multi-language support, and no-signup policy make it the most versatile free summarizer available. QuillBot is a better choice if you need an all-in-one writing toolkit. TLDR This is fine for quick URL-based summaries but lacks the depth of SummarizePro.
