What it is

Use AI to research and summarize anything across the internet, like a super-smart research assistant.

What you can make with it

Automations that summarize long conversations, news articles, or podcasts into a 1-2 minute summary.

How it helps

It saves time and effort by automatically condensing complex information into a brief summary.

Real use case example

"A founder, looking to summarize 10 hours of investor feedback, uses Claude's Supercharge to automatically condense it into a 2-page report. She inputs keywords, such as 'product roadmap' and 'funding,' and receives a summarized version in minutes. She then uses this report to inform her product strategy."

If you're new

Pick this up when you want to automate simple research tasks, like summarizing news articles or social media conversations.

If you're senior

Senior engineers will use this when they need a reliable AI research agent that can handle complex tasks, like synthesizing long-form content.

Common confusion cleared up

This skill is specifically designed to handle complex research tasks, not simple data entry or content generation tasks.
