PerfectLineup is an India-based fantasy sports analysis and lineup-building service developed and managed by Viscus Infotech Ltd. It uses artificial intelligence, machine learning, and sports data to help users create fantasy cricket and soccer teams. The platform analyzes thousands of data points and offers generated lineups for different contest styles, including grand leagues and small leagues.

Its tools include player statistics, venue reports, performance-based cheatsheets, player-versus-player comparisons, and a contest simulator that estimates how a team may perform without entering a contest. Users can generate multiple teams, apply different selection logic, set player limits, and receive teams by email, depending on their plan. Paid subscriptions offer different team-generation and simulator features, while a three-day free trial is also advertised. PerfectLineup Labs showcases experimental AI and machine-learning tools for lineup generation.

The service also provides match and series information, sports content, videos, and app access. PerfectLineup describes itself as an educational analysis platform, not a host of fantasy contests, and states that access is for users aged 18 and older, subject to regional restrictions.
