How can I have an AI tool interact with websites or software that doesn't have an official API?

One approach discussed was using the Claude in Chrome extension, which lets Claude browse and click through websites much like a human would, just a bit slower. You install the extension, then tell Claude what you want done (e.g., 'do this in Claude and Chrome') and it can navigate between tabs, take screenshots, and complete tasks such as pulling branding elements from one site to build a template in another (e.g., copying a website's colors and fonts into a newsletter template in Beehiiv). For more advanced use, you can ask it to inspect network requests to figure out how to use a site's unofficial/undocumented API. One participant noted Claude in Chrome can be finicky — reliable for easy tasks like building a webflow item, but they'd avoid it for higher-stakes tasks like sales tax registration. Other browser automation tools mentioned as emerging alternatives were 'browser base' and 'Strawberry browser,' with a note that Bizora might eventually use these on the back end for web research.
