SkimIt.ai

What is SkimIt.ai?
SkimIt.ai is an email summarizer that turns any article link into a short recap delivered to your inbox. You email a URL to [email protected] with the link as the first URL in the message body, and the service replies with a summary in about 10 minutes. There is no app install or account signup on the site.
Browser extensions and reader apps keep you inside another interface. SkimIt stays in email so you can forward links from mobile share sheets and CC friends who get both your message and the generated recap. The trade-off is speed: summaries can take up to 15 minutes when servers are busy, and accuracy is presented as entertainment-grade rather than publication-ready.
Busy readers, founders sharing essays, and teams passing around long posts are the natural audience. OpenAI GPT powers the backend processing, and support questions go to [email protected] if a summary is delayed or lands in spam.
SumUp

What is SumUp?
SumUp was a summarizer web app and Chrome extension that condensed articles into short summaries plus auto-generated Q&As and comment prompts. The sumup.page domain no longer responds to requests.
When live, users pasted an article URL or browsed a Feeds page and SumUp returned a summary with discussion points. A Chrome Web Store listing still references sumup.page, but automated fetches, Exa, and Firecrawl all fail to retrieve any page content now.
Directory listings marked SumUp inactive in June 2024. The product was attributed to Cowork AI and described as freemium before the site went offline.
