The free 9-part video course, Explore The Coin Daily Research, walks through setup and the full workflow — charts, comparisons, news and using the tools in ChatGPT or Claude: https://www.youtube.com/playlist?list=PLKY7CRxbV8Fc Ask your assistant for a chart and it arrives in the conversation — scrub Bitcoin's week, set an A-to-B range, and see the move in numbers. Pull funding, open interest, liquidations and order-book depth. Catch hourly regime shifts. Compare whole sectors, like DeFi against AI tokens. Follow source-linked news and ticker video coverage, or read the latest published Market Update with its chapters.

TweakThis hands your coding agent the feedback left on your website. You or your client point at an element with the Chrome or Firefox extension and write a note; TweakThis captures the page, the element's selectors, HTML and styles, and a screenshot.
