Reviewers mostly praise Streak for being easy to use inside Gmail, which makes customer tracking, project management, and other workflows feel faster and more practical than heavier CRM tools. Several mention AI and automation, especially autofill, as real time-savers, and some say it works well for small teams or solo operators. The main criticism is pricing and feature gating: multiple reviewers want more capability in lower-cost plans, while one long-term user says it does not scale well and feels expensive for growing teams.
