Probably you're using an employment website, which lets you submit your CV to job offers and keep track of its history: when and to which companies was it sent, whether they accepted it or not...
But if you use several websites, that means different histories, hard to compare ("I think I saw this offer somewhere else before..."). And let alone all CVs delivered by other ways (a friend told me, I just went to their offices... ).
CV Agenda serves to keep a personal record of all the job offers you're applying for. You can create profiles with the details of each offer, company and interview, so you'll be able to search them by different criteria (job, location, company ...).
