I like the site (agree that it looks more Resume aaS versus Cover Letter aaS).

Could you elaborate more on the multiple narratives? If I have a long and sordid job history with multiple industries, am I picking only specific companies/positions that I worked with in my application, or am I picking bullet points within the company? I'm slightly confused why Tom Webb would be an iOS developer, Lead Front end, and Customer Service Manager. Maybe iOS, front end, and something else programming related would better illustrate the example. The example job application doesn't change going between Tom Webb and Tina Zuick to really drive this home.

If I have multiple narratives, do they each have unique URLs?
