Run thousands of ready-made web scrapers and AI agents from one cloud platform
Over one hundred thousand ready-to-run scrapers and automation tools covering social media, maps, e-commerce, real estate, and general web crawling.
Connect Apify Actors directly to AI assistants and agents so they can search the store, run scrapers, and pull structured results as tool calls.
Managed proxy rotation and unblocking are built into the platform, so scrapers keep working when target sites add defenses.
An open-source crawling library plus Python and JavaScript SDKs for building custom Actors with Playwright, Puppeteer, Selenium, or Cheerio.

AI research platform for reading, understanding and writing scientific papers
Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.
Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.
An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.
Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.
