Last updated: 15 June 2026 · Grompalytics is an independent, non-commercial prototype / proof of concept.
By using Grompalytics (“the Service”) you agree to these terms. The Service is provided free of charge as an unofficial tool for evaluation purposes and is not affiliated with or endorsed by Riot Games.
Grompalytics reads public League of Legends match data via the official Riot Games API and produces a computer-generated, move-by-move review intended to help you reflect on and improve your own play. The analysis is generated with the assistance of a third-party large language model (DeepSeek). The Service is post-game and reflective only: it provides no real-time, in-game assistance, overlays, cooldown or objective timers, or any other in-match advantage.
Grompalytics is an unofficial, third-party application built on the Riot Games API. It operates in accordance with Riot's Developer Terms and General Policies: it does not create an alternative to Riot's official ranking systems (no MMR/ELO calculators), does not de-anonymise players or expose historic Riot IDs, does not provide any in-game advantage, and keeps its Riot API key server-side. Your use of League of Legends remains governed by Riot Games' own Terms of Service.
Computer-generated analysis may be incomplete or incorrect and is offered for guidance only, with no guarantee of results. The Service is provided “as is”, without warranties of any kind, and is under active development.
League of Legends and all related game assets (champion images, items, runes, summoner spells, and profile icons) are the property of Riot Games, Inc. and are served via Riot's Data Dragon for use by third-party developers. Grompalytics claims no ownership of Riot's intellectual property and does not use the Riot Games logo or trademarks as its brand.
To the maximum extent permitted by law, the operator is not liable for any damages arising from use of this prototype.
These terms may change as the prototype evolves; continued use after changes constitutes acceptance. For questions, contact the operator at the email associated with the project.
