A: Hi. Thanks for your question. Onboarding call is primarily to walk through the user regarding full features of Paperguide in a live demo and discuss how the user can use Paperguide for their specific requirements. While some users can easily get a hang of how to use Paperguide using demo videos and help pages, onboarding call is just an add on facility. The primary differences between tier 1 and other tiers lies in the feature limits for AI generation rate limits, no. of columns that can be extracted and number of papers that can be analysed using literature review and extract data at a time and the storage capacity for reference manager files. While tier 1 is useful for occasional users, tier 2 and others are meant for frequent users who need more support and capabilities
