Questions
What's trending in AI today?
The Today column is today so far (UTC), ranked again through the day; each morning the full day just ended is ranked once more and keeps its own page. The ranking is by trend score: the names that drew the most attention on Hacker News, Reddit, YouTube, GitHub, Wikipedia, Google News, Bluesky, Mastodon, Hugging Face, Product Hunt, arXiv and Google Trends compared with their own usual level. Open any term for its history and the links behind it.
How is the trend score computed?
For each source, a term's share of that day's engagement (points, comments, stars, upvotes, rank) and of its items; the shares are weighted by source and summed, then compared with the term's own average over the previous 14 days. Size and change both count, so an always-discussed company only leads on a day something happens. The full method is on the Method page.
How do I see trending AI tools this week?
The Risers page compares each term's summed score over the last seven days with the seven before, and the AI products and tools category page ranks just that category.
Is a term trending right now?
Search for it (press / or Cmd K). Its page shows the daily score line, the first day it ranked, its peak and every day it made the top 20, with the posts, repositories and papers that carried it.
Why are X and LinkedIn not sources?
Neither has a free API for reading posts or trends, and scraping them breaks their terms. Trending uses only sources that publish their data openly; posts on X reach the score when news stories, Reddit or Hacker News link to them.
A term is misnamed, split in two or not a tech term. How do I fix it?
Every term page has Suggest a correction: rename it, change its category, merge it into another term or mark it as not a term. Each suggestion is reviewed before anything changes.
