The free model is what makes this work for adoption. Most people won't pay for a summarization tool upfront without knowing if they'll actually use it. The 30-second turnaround lets you batch-process a research queue without friction - I've been using it for educational content deep-dives. One thing that would strengthen this: integration with note-taking systems. Being able to automatically push summaries into Notion or Obsidian would make this a research pipeline essential rather than just a convenience tool.
