# DawnTrend > DawnTrend is a research site that measures where public attention is moving across AI companies, startups and markets. It uses monthly Google search demand for each company’s own name, from Google search estimates, and compares it with website traffic where that is available. It covers the S&P 500, the Nasdaq-100, the Fortune 100, every Y Combinator company and 80 curated AI companies and topics, grouped into sectors and industries with a fixed formula: the Search Score, from 0 to 100, blends scale, twelve-month momentum and staying power. Browsing is free. A free account adds a daily search allowance, bulk research, website lookups and an API. Search demand measures interest, not revenue, users or adoption. Every figure is an estimate shown with its source, the months it covers and the date it was collected, and none of it is investment advice. ## Key pages - [Home](https://dawntrend.com/): what is breaking out right now - [Use cases](https://dawntrend.com/use-cases): investors, analysts, marketers, founders, sales and AI builders, each with a path through the product - [Dawn Index](https://dawntrend.com/dawn-index): brand attention rankings: search demand, purchase intent and site visits in one 0 to 100 score (Markdown: https://dawntrend.com/dawn-index.md) - [Markets](https://dawntrend.com/markets): S&P 500, Nasdaq-100, Fortune 100 and Y Combinator, by sector - [Dawn Index AI industries](https://dawntrend.com/industries): eight AI industries as indexes - [How it works](https://dawntrend.com/about): mental model, formulas, limits, FAQ (Markdown: https://dawntrend.com/about.md) - [Site lookup](https://dawntrend.com/site): the keywords a website ranks for - [API documentation](https://dawntrend.com/api-docs): free API with a Bearer key - [Pricing](https://dawntrend.com/pricing.md): Guest and Free account limits - [Sitemap](https://dawntrend.com/sitemap.xml) ## Actions an agent can take - Read any company’s 12-month search demand at https://dawntrend.com/trend/{slug} (Markdown: https://dawntrend.com/trend/{slug}.md); slugs are the company name in lowercase with hyphens, for example https://dawntrend.com/trend/unitree. - Call the JSON API with a free key: GET https://dawntrend.com/api/v1/trend?keyword=claude+code. - Read machine-readable site facts: https://dawntrend.com/api/content. ## Data notes - Search demand: Google monthly search estimates; global; up to twelve months. - Website traffic: third-party visit estimates for Y Combinator sites. - Lists: Wikipedia (S&P 500, Nasdaq-100, Fortune 100), Wikidata (websites), Y Combinator directory. - Every page prints the months it covers and the collection date.
