MarkLayer and Userback look similar but solve different problems. Userback's main mode is a feedback widget you embed on your own product so end users can submit annotated feedback to you. MarkLayer is a Chrome extension your team uses to annotate any webpage (including third-party pages, staging sites, and competitor products) and share the result.
