The Verdict
Mendeley is built for researchers and phd students, with a focus on reference-management and pdf-annotation. Sprig targets product managers and ux researchers and leads with in-app-surveys and session-replay.
Both tools use custom enterprise pricing — you'll need to contact sales for a quote, which makes direct cost comparison difficult.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Bottom line: Sprig has a slight overall edge — but if free matters most to you, Mendeley may still be the right call.
