Coupon codes ranked by whether they actually worked
Each promo code shows how many shoppers tried it, how often it worked and when it last succeeded, with listings ordered by likelihood of working rather than payout.
A free Chrome extension detects the store you are shopping at and tries the strongest available codes directly in the checkout field.
Codes and deals for a very wide range of retailers, browsable by category, by store name, or through regional views for the US, UK, Australia and Canada.
The service compares the total you would pay so you can see which code or offer actually results in the lowest price before completing an order.
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.
